<h2>
<a NAME="Introduction"></a>Introduction</h2>
<span CLASS=LXRLONGDESC> <span CLASS=LXRSHORTDESC>LiveConnect is a library that
permits JavaScript and Java virtual machines to interoperate.</span> Specifically,
it enables JavaScript to access Java fields, invoke Java methods and enables Java
to access JavaScript object properties and evaluate arbitrary JavaScript.</span>
LiveConnect was originally an integrated feature of both the Netscape Navigator
browser and Netscape's server-side JavaScript. Now, it is a standalone library
that can be embedded within other projects, such as the Mozilla browser. More
information on LiveConnect can be found by <a href="http://developer.netscape.com/find/find.cgi?scope=LiveConnect&browse-category=&ui=sr&chunk-size=&page=1&taxonomy=DevEdge+Online">searching
the index on Netscape's DevEdge site</a>.&nbsp; This README assumes basic familiarity
with <a href="http://lxr.mozilla.org/mozilla/source/js/src/README.html">JSRef</a>,
the reference implementation of JavaScript, and with the LiveConnect technology.
<p>The JSRef project/makefiles (located in another directory) build a library
or DLL containing the JavaScript runtime (compiler, interpreter, decompiler,
garbage collector, atom manager, standard classes).&nbsp; The LiveConnect project/makefiles
build a library that links with both JSRef and any Java Virtual Machine (JVM)
that implements the Java Native Interface (JNI), as specified by JavaSoft.&nbsp;
It then compiles a small "shell" example program and links that with the library
to make an interpreter that can be used interactively and with test scripts.&nbsp;
See the <a href="#sample_shell_interaction">sample shell interactions</a>.

<h2>
<a NAME="New_Features"></a>New features</h2>
The following features were not available in the versions of LiveConnect that
were integrated with Netscape Navigator versions 4.x and earlier.&nbsp; For information
on LiveConnect version 1, which was used in Navigator versions 3 and 4, and Enterprise
Server 3, see <a href="http://developer.netscape.com/find/find.cgi?scope=LiveConnect&browse-category=&ui=sr&chunk-size=&page=1&taxonomy=DevEdge+Online">Netscape's
DevEdge site</a> or any number of 3rd-party publications.)
<h4> LiveConnect version 3 (8/31/99)</h4>
<ul>
<li> In previous versions of LiveConnect, when more than one overloaded Java
method was compatible with the types of arguments in an invocation from JS,
the choice of Java method was made arbitrarily, by using the first one enumerated
by the Java reflection APIs.&nbsp; Unfortunately, the ordering of methods
when enumerating is not governed by any specification, so differences between
JVM vendors could lead to inconsistencies in LiveConnect behavior.&nbsp; Now,
a <a href="http://www.mozilla.org/js/liveconnect/lc3_method_overloading.html">JVM-independent
set of rules</a> is used to choose among a set of overloaded methods.&nbsp;&nbsp;
Informally, the method with Java parameter types that most&nbsp; closely match
the JavaScript types is chosen.<BR>
<BR>
</li>
<li> The weak correspondence between the JS language typing system and Java's
may result in ambiguity and/or shadowing when resolving among overloaded Java
methods, even when using LC3's improved method overload resolution algorithm
(see above).&nbsp; For example, JS's number type can map to a Java method
argument that has any floating-point or integral types: byte, char, short,
int, long, float, double.&nbsp;&nbsp; If necessary, it is now possible to
bypass the method overload resolution process and explicitly specify the method
to be invoked:</li>
<BR>
<br>
&nbsp;
<ul>
<tt>myPrintMethod = java.io.PrintStream["print(double)"];</tt> <br>
<tt>myPrintMethod(13);</tt>
</ul>
<br>
<li> Static methods can now be invoked using either the class name or a reference
to an instance of the class.&nbsp; (Older versions of LiveConnect allow only
the former.)<BR>
<BR>
</li>
<li> It is no longer necessary to convert Java Strings to JS strings before
using them as the receivers of JS string methods, which is typically done
by appending an empty string to the Java string, e.g.
<BLOCKQUOTE>
<P> <tt>&nbsp;&nbsp;&nbsp; s = new java.lang.String("foo")</tt> // s contains
a Java string<br>
<tt>&nbsp;&nbsp;&nbsp; s = s + "";&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
</tt>// s is now a JS string <br>
<tt>&nbsp;&nbsp;&nbsp; m = s.match(/o?/)</tt> </P>
</BLOCKQUOTE>
</li>
<p>The explicit conversion to a JS string is no longer required because <i>java.lang.String</i>
objects are treated as a special case that "inherit" all the methods of JS
strings, i.e. so that the second statement in the example above is now superfluous.<BR>
<BR>
<li> Similarly, JavaArray objects "inherit" the methods of JS's <tt>Array.prototype</tt>,
so it is possible to apply many, though not all, of the JS array utility methods
such as <tt>reverse()</tt> and <tt>join()</tt> to JavaArray objects.<BR>
<BR>
</li>
<li> There is now support for the <tt>instanceof</tt> and <tt>in</tt> operators.&nbsp;
These operators are currently proposed for inclusion in the ECMA-2 standard.<BR>
<BR>
</li>
<li> LiveConnect has been extended to take advantage of JavaScript exceptions,
a language feature that debuted in JavaScript 1.4.&nbsp; Now, when JavaScript
calls into Java, any Java exceptions are converted to JS exceptions which
can be caught using JS try-catch statements.&nbsp; Similarly, JS exceptions
are propagated to Java wrapped in an instance of <i>netscape.javascript.JSException</i>.<BR>
<BR>
</li>
<li>JavaScript Array objects can now be passed to Java methods that expect a
Java array as an argument. <BR>
LiveConnect will create a new Java array of the appropriate type with a length
equal to that of the JS Array object. Each element of the Java array is filled
in by converting the corresponding element of the JS array, including undefined
elements, to an equivalent Java value. Note: Since the contents of the JS
array are copied, side-effects made by the invoked Java method to the Java
array will not be reflected in the JS array argument. </li>
</ul>
<h4>
LiveConnect version 2 (7/31/98)</h4>
<blockquote>
<li> The Java methods of <i>java.lang.Object</i> are now invokeable methods
of <tt><font size=+1>JavaArray</font></tt> objects, matching the behavior
of arrays when accessed from Java<i>.</i>&nbsp; (Java arrays are a subclass
of <i>java.lang.Object</i>.) For example, Java's <tt>getClass()</tt> and <tt>hashCode()</tt>
methods can now be called on <tt>JavaArray</tt> objects.&nbsp; (In prior versions
of LiveConnect, the methods of <i>java.lang.Object</i> were only inherited
by non-array Java objects.)</li>
<p>Note that this change has caused the string representation of JavaArray objects
to change.&nbsp; Previously, the JavaArray toString() method always printed
"<tt><font size=+1>[object JavaArray]"</font></tt> for all <tt>JavaArray</tt>'s.&nbsp;
Now, the Java <tt>java.lang.Object.toString()</tt> method is called to convert
JavaArray objects to strings, just as with other, non-array Java objects that
are accessible via LiveConnect. <tt>java.lang.Object.toString()</tt>is defined
in the <i>Java Language Specification</i> to return the value of the following
expression:
<p><tt><font size=-1>getClass().getName() + '@' + Integer.toHexString(hashCode())</font></tt><BR>
<br>
&nbsp;
<li> A one-character string is now an acceptable match for an argument to a
Java method of type <tt>char</tt>.&nbsp; (In earlier versions of LiveConnect,
the only acceptable match for a <tt>char</tt> had to be a JavaScript value
that was convertible to a number.)&nbsp; For example, the following is now
possible:</li>
<p><tt><font size=-1>c = new java.lang.Character("F")</font></tt><BR>
<br>
&nbsp;
<li>
A JavaClass object is now an acceptable match for an argument to a Java
method of type <i>java.lang.Class</i>.&nbsp; For example, you can now write:</li>
<p><tt><font size=-1>java.lang.reflect.Array.newInstance(java.lang.String,
3)</font></tt>
<p>instead of the more verbose:
<p><tt><font size=-1>jls = java.lang.Class.forName("java.lang.String")</font></tt>
<br>
<tt><font size=-1>java.lang.reflect.Array.newInstance(jls, 3)</font></tt>
<p><br>
&nbsp;
</blockquote>
<h2>
<a NAME="Compatibility"></a>Compatibility</h2>
Unlike this standalone/component release, all previous versions of LiveConnect
appeared only as an integrated feature of Netscape Navigator or the Enterprise
Server.&nbsp; The variants of LiveConnect that appeared in Navigator versions
3.x and 4.x all behave much the same, modulo bugs.&nbsp; For brevity we refer
to this classic version of LiveConnect as "LC1" (LiveConnect version 1) and this
most recent release as "LC3".&nbsp; With a few exceptions LC3 provides a superset
of LC1 features. (There was an intermediate LiveConnect release known as "LC2"
in 7/98, but it was not used in any products.)
<ul>
<li> As in LC1, JavaScript objects appear to Java as instances of <i>netscape.javascript.JSObject</i>.&nbsp;
In LC1, two <i>JSObject</i>'s could be tested for equality, i.e. to see if
they refer to the same instance, by using the `==' operator.&nbsp; Instead,
developers must now use the <tt>equals()</tt>method of <i>netscape.javascript.JSObject</i>
for comparison, a method that overrides <tt>java.lang.Object.equals()</tt>.&nbsp;
Note that using <tt>equals()</tt> instead of `==' will work the same in all
versions of LiveConnect, including LC3</li>
<p>[It is not possible to replicate the identity behavior of the `==' operator
that LC1 provides without the use of "weak" references, i.e. references that
do not contribute to making a Java object reachable for purposes of garbage
collection, but which nonetheless allow reference to an object as long as
it is reachable by other means.&nbsp; The use of weak references is not portable,
however.&nbsp; It is not part of the JNI or JDK 1.1 and it is not provided
on all JVMs.&nbsp; The JDK1.2 release includes standard support for weak references.]<BR>
<br>
&nbsp;
<li> It's possible that, in a set of overloaded Java methods, more than one
method is compatible with the types of the actual arguments in a call from
JavaScript to Java via LiveConnect.&nbsp; LC1 and LC2 resolved these ambiguities
in a simplistic manner, by simply invoking whatever method was enumerated
first by the JVM.&nbsp; The enumeration order of reflected methods using <i>java.lang.reflect</i>&nbsp;
is not specified by Sun and may differ among vendor's JVMs, i.e. enumeration
could be in order of classfile appearance, hashtable order, etc.&nbsp; Hence,
the Java method chosen when there is more than one compatible method may vary
depending on the JVM.&nbsp; With the Netscape and Sun JVMs, it is possible
to change the behavior of an LC1/LC2 program by changing the order that Java
methods appear in a source file, thus changing the method enumeration order.</li>
<p>In LC3, a new method overload resolution algorithm is used.&nbsp; Informally,
the method with Java parameter types that most&nbsp; closely match the JavaScript
types is chosen.&nbsp; You can read all the gorey details in the <a href="http://www.mozilla.org/js/liveconnect/lc3_method_overloading.html">spec</a>.<BR>
<br>
&nbsp;
<li> There are several minor changes in error handling to make LiveConnect more
conformant to ECMAScript.&nbsp; These include, for example, making any attempt
to delete JavaObject, JavaClass or JavaPackage properties fail silently, rather
than causing an error.&nbsp; Also, some error messages have been changed to
be more informative.&nbsp; These changes should generally be backward-compatible
with LC1 because few programs that use LiveConnect will depend on the exact
behavior of LiveConnect when handling errors.</li>
</ul>
<h2> <a NAME="Limitations"></a>Limitations/Bugs/To-Do<BR>
</h2>
<ul>
<li> The efficiency of calling Java methods leaves something to be desired,
due to the convoluted nature of implementing native methods for JS.&nbsp;
JS_CloneFunctionObject() is called for every Java method invocation and the
inability to store private data in a JSFunction object requires that the method
table be searched twice instead of once for every invocation.<BR>
<BR>
</li>
<li> When Java objects are referenced from JS, they are entered into a hash
table, so as to ensure that the same JS Object wrapper is used every time
a particular Java object is reflected into JS.&nbsp; In this way, the behavior
of the JS '==' and '===' operators are preserved.&nbsp; Unfortunately, the
hash table may grow quite large (objects are only removed from the hash table
when finalized).&nbsp; In thread-safe systems, the hash table must be locked
when accessed, leading to slow performance. One alternate solution would be
to make it possible to overload JS's equality-test operators, so that the
hash table would no longer be required.<BR>
<BR>
</li>
<li> Initially, JavaClassDescriptor objectswere reference-counted to permit
free'ing of unused descriptors.&nbsp; However, it's relatively common to develop
cycles in the graph of JavaClassDescriptors, which leads to unused JavaClassDescriptors
that have non-zero reference counts. For that reason, JavaClassDescriptors
are not free'ed until JSJ_Shutdown().&nbsp; Luckily, the amount of memory
used by JavaClassDescriptors tends to be relatively small.<BR>
<BR>
</li>
<li> The LiveConnect API is designed to allow multiple JVMs to be used simultaneously
in the same executable (although each JSContext is limited to interaction
with at most one JVM).&nbsp; However, the API is not fully implemented.&nbsp;
For example, many global variables will need to become members of the JSJavaVM
struct so that they are stored on a per-JVM basis.<BR>
<BR>
</li>
<li> Java and JavaScript use independent garbage collection systems. A reference
between the two worlds must, therefore, take the form of a GC root. It's possible
to create uncollectable objects when cyclic graphs cross the boundary between
JS and Java, e.g. a JS object that refers to a Java object that refers back
to the original JS object. There is no simple solution to this dual-GC problem.
Luckily, such cyclic object graphs are extremely rare. </li>
</ul>
<h2>
<a NAME="Build_conventions"></a>Build conventions</h2>
<P>The following directions are for building the standalone version of LiveConnect.
To build the version that's used in the Mozilla browser, see the <A HREF="http://www.mozilla.org/docs/">Mozilla
build documentation</A>.</P>
<P>On all platforms, you must update your JVM's <tt>CLASSPATH</tt> to point to
the <tt>js/src/liveconnect/classes</tt> subdirectory.&nbsp; If you do not, LiveConnect
will still operate but with the limitation that JS objects may not be passed
as arguments of Java methods and it will not be possible to call from Java into
JavaScript, i.e. the <i>netscape.javascript.JSObject</i> class will be inaccessible.&nbsp;
Another downside of operating without these classes is that Java error messages
will not include a Java stack trace, when one is available.&nbsp; If your <tt>CLASSPATH</tt>
is set improperly, you will see a message like, "<tt>initialization error: Can't
load class netscape/javascript/JSObject</tt>" when starting a LiveConnect debug
build. </P>
<p>By default, all platforms build a version of LiveConnect that is <i>not</i>
threadsafe.&nbsp; If you require thread-safety, you must also populate the <tt>mozilla/dist</tt>
directory with <a href="http://www.mozilla.org/docs/tplist/catCode/nsprdesc.htm">NSPR</a>
headers and libraries.&nbsp; (NSPR implements a portable threading library,
among other things.&nbsp; The source is downloadable via <a href="http://www.mozilla.org/cvs.html">CVS</a>
from <tt><a href="http://lxr.mozilla.org/mozilla/source/nsprpub">mozilla/nsprpub</a></tt>.)&nbsp;
Next, you must define <tt>JS_THREADSAFE</tt> when building LiveConnect, either
on the command-line (gmake/nmake) or in a universal header file.&nbsp; Note
that JSRef must also be built with <tt>JS_THREADSAFE</tt>.
<p>One important note about building on Windows: There are two independent build
systems (in addition to the Mozilla browser build system). One of them uses
the IDE project files and the other uses gmake and makefiles. The former will
be preferred by most for debugging and the latter is more complete, since it
builds the necessary Java classes in addition to compiling the LiveConnect C
code.
<ul><b>Windows</b>
<ul>
<li>
Build the JS runtime and interpreter, <tt>js32.dll</tt>, by using the
<a href="http://lxr.mozilla.org/mozilla/source/js/src/README.html#Build">normal
JSRef build procedure</a>.</li> <li> Set the <tt>JDK</tt> environment variable to point to the top-level JDK directory,
e.g. <tt>D:\jdk1.1.5</tt>.&nbsp; This is used to establish paths for header
file inclusion, linking and execution.&nbsp; If you are not using Sun's
JVM, the project files may require manual tweaking to set these paths correctly.</li>
<li> Use MSVC 5 or MSVC 6 with the <tt>LiveConnectShell.dsw</tt> project file.&nbsp;
<font color="#993300">NOTE: makefile.win is an nmake file used only for
building the JS-engine in the Mozilla browser.&nbsp; Don't attempt to use
it to build the standalone JS-engine.</font></li>
<li>
The output files (DLLs and executables) are placed in either the <tt>js\src\liveconnect\Debug</tt>
or the <tt>js\src\liveconnect\Release</tt> directory.</li>
<li>
The LiveConnect-enabled shell is named <tt>lcshell.exe</tt> and appears
in the output directory.</li>
<li>
You must have the JVM DLL in your <tt><font size=+1>PATH</font></tt> environment
variable in order to run.&nbsp; If you are using the Sun JDK, the DLL appears
in the JDK's bin directory, e.g. <tt>D:\jdk1.1.5\bin\javai_g.dll</tt>.</li>
<li>
Use any Java compiler to compile the java source files in the <tt>js\src\liveconnect\classes\netscape\javascript</tt>
directory.</li>
<li> Update your JVM's <tt>CLASSPATH</tt> to point to the <tt>js\src\liveconnect\classes</tt>
subdirectory.&nbsp; (See above)<br>
<BR></li>
</ul>
<b>Mac OS</b>
<ul>
<li>
Using CodeWarrior Pro 3 is recommended, though the project files will probably
also work with CodeWarrior Pro 4.</li>
<li>
Install Apple's JVM, MRJ 2.0 (or later), and the <a href="ftp://dev.apple.com/devworld/Java/MRJSDK2.0.1EarlyAccess4.hqx">MRJ
SDK v2.0.1ea4</a>.&nbsp; Note: You do not need to install MRJ if you are
running a recent version of MacOS 8, since it is shipped with the OS.</li>
<li>
Copy the folders <tt>CIncludes</tt> &amp; <tt>Libraries</tt> from the SDK's
<tt>Interfaces&amp;Libraries</tt> directory to <tt>js:src:liveconnect:macbuild:JavaSession</tt>.</li>
<li>
Build the LiveConnect test application, <tt>LiveConnectShell</tt>, with
<tt>js:src:liveconnect:macbuild:LiveConnectShell.mcp</tt>.</li>
<li>
Build <tt>liveconnect.jar</tt> with <tt>js:src:liveconnect:macbuild:LiveConnect.mcp</tt>.</li>
<li>
Make an alias to <tt>liveconnect.jar</tt> and place it in "<tt>{SystemFolder}Extensions:MRJ
Libraries:MRJClasses</tt>".<br>
<BR></li>
</ul>
<b>Unix</b> (also works on Windows)
<ul>
<li> <font color="#000000">Use '<tt>gmake -f Makefile.ref</tt>' to build.
To compile optimized code, pass <tt>BUILD_OPT=1</tt> on the gmake command
line or preset it in the environment or <tt>Makefile.ref</tt>.&nbsp; </font><font color="#990000">NOTE:
Do not attempt to use <tt>Makefile</tt> to build.&nbsp; This file is used
only for building LiveConnect in the Mozilla browser.</font></li>
<li> <font color="#000000">Each platform on which LiveConnect is built must
have a *.mk configuration file in the <tt>js/src/liveconnect/config</tt>
directory.&nbsp; The configuration file specifies the JVM headers/libraries
used and allows for customization of command-line options.&nbsp; To date,
the build system has been tested on Solaris, AIX, HP/UX, OSF, IRIX, x86
Linux and Windows NT. Most platforms will work with either the vendor compiler
or gcc.</font></li>
<li>Update your JVM's <tt><font size=+1>CLASSPATH</font></tt> to point to
the <tt>js/src/liveconnect/classes</tt> subdirectory.&nbsp; (See above)</li>
</ul>
</ul>
<h2>
<a NAME="coding_conventions"></a>Naming and coding conventions:</h2>
<ul>
<li>
Public function names begin with JSJ_ followed by capitalized "intercaps",&nbsp;
e.g. JSJ_ConnectToJavaVM.</li>
<li>
Extern but library-private function names use a jsj_ prefix and mixed case,
e.g. jsj_LookupSymbol.</li>
<li>
Most static function names have unprefixed, underscore-separated names:
get_char.</li>
<li>
But static native methods of JS objects have intercaps names, e.g., JavaObject_getProperty().</li>
<li>
And library-private and static data use underscores, not intercaps (but
library-private data do use a js_ prefix).</li>
<li>
Scalar type names are lowercase and js-prefixed: jsdouble.</li>
<li>
Aggregate type names are JS-prefixed and mixed-case: JSObject.</li>
<li>
Macros are generally ALL_CAPS and underscored, to call out potential side
effects, multiple uses of a formal argument, etc.</li>
<li>
Four spaces of indentation per statement nesting level.&nbsp; The files
are space-filled, so adjusting of your tab setting should be unnecessary.</li>
<li>
I don't bow down to the ancient "80 columns per line" gods, since most
of us are not using vt100's to read source code.&nbsp; My rule of thumb
is to use no more than 95 columns per line, but exceptions are made to
format tables or table-like code.</li>
<li>
DLL entry points have their return type expanded within a JS_EXPORT_API()&nbsp;
macro call, to get the right Windows secret type qualifiers in the right
places for both 16- and 32-bit builds.</li>
<h2>
<a NAME="API"></a>The LiveConnect API</h2>
All public LiveConnect entry points and callbacks are documented in
<A HREF=http://lxr.mozilla.org/mozilla/source/js/src/liveconnect/jsjava.h>jsjava.h</A>,
the header file that exports those functions.

* <li>JSObject is converted to the original JavaScript object
* <li>Any other Java object is converted to a JavaScript wrapper,
* which can be used to access methods and fields of the java object.
* Converting this wrapper to a string will call the toString method
* on the original object, converting to a number will call the
* doubleValue method if possible and fail otherwise. Converting
* to a boolean will try to call the booleanValue method in the
* same way.
* <li>Java arrays are wrapped with a JavaScript object that understands
* array.length and array[index]
* <li>A Java boolean is converted to a JavaScript boolean
* <li>Java byte, char, short, int, long, float, and double are converted
* to JavaScript numbers
* </ul>
* Values passed from JavaScript to Java are converted as follows:<ul>
* <li>objects which are wrappers around java objects are unwrapped
* <li>other objects are wrapped with a JSObject
* <li>strings, numbers and booleans are converted to String, Double,
* and Boolean objects respectively

* JavaMember's are a strange beast required only to handle the special case
* of a public field and a public method that appear in the same class and
* have the same name. When such a field/method is used in Java, the compiler
* can statically determine from context whether the field or the method is
* being referenced, but that is not possible with JavaScript. For example:
*
* ambiguousVal = javaObj.fieldOrMethod; // ambiguousVal is a JavaMember object
* a = ambiguousVal(); // ambiguousVal used as a method value
* b = ambiguousVal + 4; // ambiguousVal used as a field value
*
* A JavaMember instance carries both the captured value of the Java field and
* the method value until the context that the value is to be used in is known,
* at which point conversion forces the use of one or the other.

Unfortunately, Java provides no way to find out whether a particular
name is a package or not. The only way to tell is to try to load the
name as a class file and, if that fails, assume it's a package. This
makes things work as expected for the most part, but it has three
noticeable problems that keep coming up:
- You can refer to a package like java.lang.i.buried.paul without
generating a complaint. Of course, you'll never be able to refer to
any classes through it.
- An annoying consequence of the above is that misspelling a class name
results in a cryptic error about packages.
- In a browser context, i.e. where applets are involved, figuring out
whether something is a class may require looking for it over the net
using the current classloader. This means that the first time you
refer to java.lang.System in a js context, there will be an attempt
to search for [[DOCBASE]]/java.class on the server.
A solution is to explicitly tell jsjava the names of all the (local)
packages on the CLASSPATH. (Not implemented yet.)

Description:
When accessing a Java field whose value is a java.lang.Array,
or if a java method returns a java.lang.Array, JavaScript should
read the value as the JavaScript JavaArray, an object whose class
is JavaArray.
To test this:
1. Call a java method that returns a java.lang.Array
2. Check the value of the returned object, which should be the value
of the array. Iterate through the array indices.
3. Check the type of the returned object, which should be "object"
4. Check the class of the object, using Object.prototype.toString,
which should be "[object JavaArray]"
5. Check the class of the JavaArray, using getClass, and compare
it to java.lang.Class.forName("java.lang.Array");
