<div align="Left"><font color="#000000">Microsoft and others have advocated
|
|
|
|
|
SOAP as a way to encode and exchange public data structures between
|
|
|
|
|
agents on the web, which is now becoming a web standard at W3C (see
|
|
|
|
|
the multiple submissions and working documents related to SOAP in the list
|
|
|
|
|
of <a href="http://www.w3.org/TR"> W3C current drafts</a>
|
|
|
|
|
). <br>
|
|
|
|
|
<br>
|
|
|
|
|
The browser client is the most universal web agent in existence,
|
|
|
|
|
and Javascript is the standard, interoperable way of scripting browsers.
|
|
|
|
|
Scriptable SOAP in browsers gives clients and servers more to say to
|
|
|
|
|
each other through existing http-xml request services, providing scripts
|
|
|
|
|
with persistence, database, and access to other web services not tied to
|
|
|
|
|
the request and response cycles of the HTML-based user interface.
|
|
|
|
|
Web data structures, exchanged in a platform-neutral way, should become
|
|
|
|
|
as fundamental to web agents as web content is today. The key to this
|
|
|
|
|
is a very natural binding to the data of Javascript so that the script can
|
|
|
|
|
simply use the data instead of tediously encoding and extracting the data
|
2002-02-18 21:44:16 +03:00
|
|
|
from the XML.</font><br>

1 SOAP Services</h2>
|
|
|
|
|
There are a number of sources for services available on the
|
|
|
|
|
web being set up, such as the <a href="http://www.xmethods.com">XMethods
|
|
|
|
|
website</a>
|
|
|
|
|
which the Mozilla implementation has used for some tests and use
|
|
|
|
|
cases. Apache also provides modules for SOAP that have been used to
|
|
|
|
|
author services for purposes of testing the Mozilla implementation (and
|
|
|
|
|
entertainment). Once it is set up, it is as simple as writing
|
|
|
|
|
a service function in Javascript, Java, or any other of a number of supported
|
|
|
|
|
languages and then writing a service description in XML to deploy the service.
|
|
|
|
|
There are toolkits available from Microsoft and other webserver providers
|
|
|
|
|
for authoring such services as well.<br>

2.1 Parameters<br>

</h3>
|
|
|
|
|
SOAP-based services exchange message envelopes which contain
|
|
|
|
|
blocks of XML data roughly corresponding to the parameters of a service
|
|
|
|
|
call. When an rpc-style message is exchanged, blocks representing
|
|
|
|
|
the regular parameter blocks are placed inside an element which identifies
|
|
|
|
|
the object and method being invoked, which is placed inside the body.
|
|
|
|
|
In a non-RPC message, the blocks are placed directly inside the
|
|
|
|
|
body instead of under the method element. <br>
|
|

2.2 Header Blocks<br>
|
|
|
|
|
</h3>
|
|
|
|
|
If there are blocks which are optional or independently added
|
|
|
|
|
or processed, these are carried in the header with an assigned role
|
|
|
|
|
and marked if the recipient is required to understand them before trying
|
|
|
|
|
to process the message.<br>

2.3 Encodings<br>
|
|
|
|
|
</h3>
|
|
|
|
|
Interpretation of each block depends upon the encoding that
|
|
|
|
|
was used, which is clearly specified in the message. If the standard
|
|
|
|
|
SOAP encoding is used, then XML Schema types control the interpretation
|
|
|
|
|
of the data within each block.<br>

|
|
|
3 Using the Mozilla Low-Level SOAP API</h2>
|
|
|
|
|
To use the low-level API, the user creates a SOAPCall object,
|
|
|
|
|
encodes the function call with a list of headers and regular parameters,
|
|
|
|
|
and invokes the call, which returns a response which contains the results
|
|
|
|
|
of the service call including a fault generated by the service which processed
|
|
|
|
|
the message if it failed, output parameters, and/or header blocks.
|
|
|
|
|
If the call is invoked asynchronously, then a function is supplied by
|
|
|
|
|
the caller which receives the response when it arrives from the remote
|
|
|
|
|
service.<br>
|
|
|
|
|
<br>
|
|
|
|
|
Besides Javascript, the below-described operations should also
|
|
|
|
|
generally work for other xpconnect-supported languages in Mozilla
|
|
|
|
|
such as C++/XPCOM and Python, because language-independent cross-platform
|
|
|
|
|
interfaces and architectures were used.<br>
|
|
|

3.1 Conventions Used Below in Descriptions of Operations<br>
|
|
|
|
|
</h3>
|
|
|
|
|
Names or descriptions in angle brackets represent values or
|
|
|
|
|
objects matching the name or description. These may be literal,
|
|
|
|
|
constructed via "new", or variables. Occasionally the same syntax
|
|
|
|
|
may represent script performing an operation. Quoted angle brackets
|
|
|
|
|
indicate a character string of the described type.<br>
|
|
|
|
|
<br>
|
|
|
|
|
So the following sample operation:<br>

2002-02-18 21:44:16 +03:00

|
|
<ul>

|
|
<li><font color="#993300"><i><Foo></i></font> = new

|
|
|
<li><font color="#993300"><i><Foo></i></font>.bar =

<font color="#993300"><i> <any value or object></i></font>
|
|
|
|
|
;</li>
|
|
|
|
|
<li><font color="#993300"><i><Baz></i></font> = <font color="#993300"><i>

|
|
|
</ul>
|
2002-03-19 03:08:15 +03:00
|
|
|
might be replaced in a real Javascript program:<br>
|
|
|
|
|
<br>
|
|
|
|
|
<code>var myFoo = new Foo(new FooFact("always","Great","Baz"));<br>
|
|
|
|
|
myFoo.bar = 3.14159265;<br>
|
|
|
|
|
var myGreatBaz = myFoo.find("Great");<br>
|
|
|
|
|
if (checkBaz(myGreatBaz)) {<br>
|
|
|
|
|
alert(myGreatBaz.description);<br>
|
|
|
|
|
}<br>
|
|
|
|
|
</code><br>
|
|
|
|
|
where "myFoo" is a variable holding an object of type Foo and
|
|
|
|
|
myGreatBaz is a variable holding an object of type Baz.<br>

3.3 Beyond Basic Operations<br>
|
|
|
|
|
</h3>
|
|
|
|
|
The above operations are what every user of the lowlevel SOAP toolkit
|
|
|
|
|
needs to invoke service requests and interpret the responses, as is easily
|
|
|
|
|
seen by looking at some of the samples (see <a href="#5_Samples_and_Testing">
|
|
|
|
|
section 5</a>
|
|
|
|
|
). The bulk of the operations that follow will be used less frequently,
|
|
|
|
|
but they need to be there for certain cases. The casual reader may
|
|
|
|
|
wish to skip the remaining tables of operations in this section, or scan
|

|
3.4 Header Operations</h3>
|
|
|
|
|
The user can send or receive header blocks for information not carried
|
|
|
|
|
in the body of the message. Sending and receiving header blocks
|
|
|
|
|
is not very different from sending and receiving parameters as described
|
|
|
|
|
above.<br>

3.5 Non-RPC Operations</h3>

For messages that are not intended to model RPC calls, there

|
|
|
|
is no method name or target object URI, and the parameters generally
|
|
|
|
|
have namespaceURIs. Otherwise, the basic operations are the same.<br>

|
3.8 Using Schema Types</h3>
|
|
|
|
|
The default SOAP encodings implement most XML built-in types,
|
|
|
|
|
as well as the basic SOAP types. In the absence of a specified
|
|
|
|
|
type, native values and objects will typically be correctly identified
|
|
|
|
|
and mapped to a corresponding schema type. There may be no perfect
|
|
|
|
|
correspondence between Javascript and XML Schema types, so they will be mapped
|
|
|
|
|
to a close corresponding type.<br>
|
|
|
|
|
<br>
|
|
|
|
|
Providing specific schema types can help the encoding produce the desired
|
|
|
|
|
results. For example, multidimensional arrays must be decoded
|
|
|
|
|
as nested arrays because Javascript only supports single-dimensional
|
|
|
|
|
arrays. If no schema type is given that identifies the array as
|
|
|
|
|
multidimensional, then a multidimensional array will be encoded as a
|
|
|
|
|
nested array. An accurate schema type can also help when encoding
|
|
|
|
|
or decoding of other complex objects such as SOAP structs.<br>
|
|
|
|
|
<br>
|
|
|
|
|
Schema types may be attached to blocks before encoding or before
|
|
|
|
|
accessing the value of a returned object to better control the encoding
|
|
|
|
|
and decoding. All schema types which are used to control the encoding
|
|
|
|
|
and decoding should come from the schema collection available through
|
|
|
|
|
the encoding (associated encodings share the same collection).<br>

3.9 Customization of Encodings</h3>
|
|
|
|
|
A specific encoding must have encoders and decoders to function.
|
|
|
|
|
Encoding or decoding of data always begins with a default encoder
|
|
|
|
|
or decoder, which then may lookup additional encoders or decoders by
|
|
|
|
|
a string key as required. For either the 1.1 or 1.2 version of
|
|
|
|
|
the default SOAP encoding, the default encoder and decoder use the schema
|
2003-03-24 07:15:34 +03:00
|
|
|
type's namespaceURI and name, separated by "#" to look up additional decoders
|
2002-03-19 03:08:15 +03:00
|
|
|
for specific schema types. Additional encoders and decoders registered
|
|
|
|
|
within the default encodings will automatically be invoked as an object
|
|
|
|
|
identified as the corresponding type is processed. Other encodings
|
|
|
|
|
can use any scheme for looking up additional encoders and decoders, or
|
|
|
|
|
none at all if all the work is done by the default encoder and decoder for
|
|
|
|
|
that encoding. Encodings which are registered with the system, such
|
|
|
|
|
as the default SOAP 1.1 or 1.2 encodings, automatically come with encoders
|
|
|
|
|
and decoders built-in, whereas new encodings have none. Custom encodings
|
|
|
|
|
may also reuse existing encoders and decoders, but there is no guarantee
|
|
|
|
|
which are present, since the mapping may vary when handling an infinite
|
|
|
|
|
set of types with a finite set of encoders and decoders.<br>
|
|
|
|
|
<br>
|
|
|
|
|
Also, there has been a proliferation of different schema
|
|
|
|
|
URIs to describe the same types, which may often even be intermixed in
|
|
|
|
|
usage, but expected to function properly. Most notably, the SOAP
|
|
|
|
|
1.1 specification used unofficial XML Schema URIs and SOAP encoding
|
|
|
|
|
schema URIs not compatible with those which are in the W3C XML Schema
|
|

|
and drafts for SOAP 1.2 specifications. It is not uncommon to
|
|
|
|
|
send and receive messages using the URIs specified in the SOAP 1.1 specification,
|
|
|
|
|
but described by WSDL using XML Schema that uses the official, correct
|
|
|
|
|
URIs. To solve these problems, the encoding permits schema URIs
|
|
|
|
|
to be aliased, both on input and on output, so that only the SOAP 1.2
|
|
|
|
|
and official XMLSchema types are used internally, while supporting the
|
|
|
|
|
other URIs. Mappings of this type are built-in for encodings which
|
|
|
|
|
are registered with the system, such as the default encodings of SOAP
|
|
|
|
|
1.1 and 1.2. The default URI mappings may be manipulated, for example,
|
|
|
|
|
to output SOAP 1.1 but with the official XML Schema URIs, without having
|
|
|
|
|
to rewrite any encoders or decoders.<br>

3.10 Security Operations</h3>
|
|
|
|
|
In browsers, the risk of allowing an externally-loaded untrusted
|
|
|
|
|
script to request information within a firewall and send it elsewhere
|
|
|
|
|
has lead to very tight sandbox restrictions, permitting external browser
|
|
|
|
|
scripts to only request xml data and services on the same domain from
|
|
|
|
|
which the script was loaded. This same restriction applies by default
|
|
|
|
|
to SOAP requests executed within the browser. This means that an
|
|
|
|
|
externally-loaded script cannot, for example, call other external services
|
|
|
|
|
unless they are in the same domain from which the page was loaded. Even
|
|
|
|
|
if the page was loaded from the user's own hard disk, the script must ask
|
|
|
|
|
for permission to make SOAP calls. A browser enhancement is planned
|
|
|
|
|
to permit more-precise control of trust between scripts and specific available
|
2002-02-18 21:44:16 +03:00
|
|
|
services.<br>
|
2002-03-19 03:08:15 +03:00
|
|
|
<br>
|
|
|
|
|
Since SOAP permits headers to be added to messages that require
|
|
|
|
|
interpretation by the recipient, this API can request a header to warn
|
|
|
|
|
the recipient that it was sent by an untrusted script loaded from a
|
|
|
|
|
specific sourceURI, and no good SOAP service will unintentionally disregard
|
|
|
|
|
the warning. If the envelope is verified and the header is added,
|
|
|
|
|
then the browser can allow the script less-restricted access to services
|
|
|
|
|
outside of its source domain. Accepting this header permits SOAP
|
|
|
|
|
services that really do want to be universally available to allow access
|
|
|
|
|
without forcing the user to risk breach of the firewall protections and/or
|
|
|
|
|
request user permission.<br>

4.1 Access to SOAP as Proxies</h3>
|
|
|
|
|
Although a SOAP call can generally be accomplished using this
|
|
|
|
|
low-level API in a few dozen lines, WSDL is a standard that contains
|
|
|
|
|
enough information to enable this to occur with no manual argument and
|
|
|
|
|
type setup required. An implementation is under development that
|
|
|
|
|
instantiates web service proxies complete with appropriate xpconnect interfaces
|
|
|
|
|
by simply loading and using information out of a WSDL file that describes
|
|
|
|
|
the service. The proxy's interface has dynamically-generated methods
|
|
|
|
|
named appropriately to match the services described in the WSDL file
|
|
|
|
|
which accept arguments of the appropriate data types and calls the appropriate
|
|
|
|
|
low-level SOAP functions with the appropriate type information, making
|
|
|
|
|
it even simpler not only to invoke services from Javascript code, but
|
|
|
|
|
to associate appropriate schema types loaded from the WSDL file with the
|
|
|
|
|
arguments. This higher level is not available in the first release.
|
|
|
|
|
When it is available, invoking WSDL-described features gets even easier
|
|
|
|
|
and more reliable.<br>

|
|
|

4.2 Arbitrary Graphs of Data</h3>
|
|
|
|
|
The SOAP specification allows objects to be passed as arguments
|
|
|
|
|
which may have originally referenced other objects that are not owned
|
|
|
|
|
in a pure hierarchy. This is represented by using an href attribute.
|
|
|
|
|
Due to the problems with leaking reference counts in COM objects
|
|
|
|
|
with cyclic references, this has not been implemented yet. Also,
|
|
|
|
|
the output of a cyclic-referencing set of objects has not been implemented.
|
|
|
|
|
Outputting of objects that do not have cyclic references currently
|
|
|
|
|
creates separate copies for each reference to an object, and with cycles
|
|
|
|
|
output may never complete. On input, hrefs are currently ignored.
|
|
|
|
|
In the future it may be possible to solve this and transmit and
|
|
|
|
|
receive arbitrarily-referencing objects, but the solution is more complex
|
|
|
|
|
than just using weak references.<br>

4.3 SOAP With Attachments</h3>
|
|
|
|
|
Many clients and servers now support automatically transmitting
|
|
|
|
|
large Mime with a SOAP message by encapsulating it in MIME, DIME, or
|
|
|
|
|
other enveloping formats. This has been anticipated in the APIs,
|
|
|
|
|
but the SOAPAttachments API is currently a place holder for this future
|
|
|
|
|
feature which is not yet implemented.<br>

4.4 New Transports and Local Services</h3>
|
|
|
|
|
Obvious new transports that would be useful include e-mail --
|
|
|
|
|
permitting a SOAP exchange to occur as an email exchange --, instant
|
|
|
|
|
messenger for peer to peer, and a local manager with a controlled security
|
|
|
|
|
model but without the size limitations, enabling SOAP to save and restore
|
|
|
|
|
arbitrary Javascript application data on the client. These services
|
|
|
|
|
require a framework, already being planned, for permitting the browser
|
|
|
|
|
to host services as well as being a good client. There are obviously
|
|
|
|
|
security issues to be solved to make these successful.<br>

4.5 Standards</h3>
|
|
|
|
|
The interfaces to the objects of this API were designed to be as
|
|
|
|
|
simple and universal as possible. We believe that we should submit
|
|
|
|
|
a note describing them and sponsor a W3C proposal to standardize an API
|
|
|
|
|
for invoking this type of service from web clients. In such an effort,
|
|
|
|
|
changes would be inevitable and welcomed as the price for interoperability
|
|
|
|
|
within web clients. Part of this API are incomplete, specifically
|
|
|
|
|
the SOAPAttachments object, which will be defined to allow encoders and
|
|
|
|
|
decoders to control uniqueness and referencing, both for resolving arbitrary
|
|
|
|
|
graphs of data (as described above in "Arbitrary Graphs of Data") as well
|
|
|
|
|
as for automatically resolving references to attached objects carried with
|
|
|
|
|
the message in an external encapsulation (as described above in "SOAP With
|
|
|
|
|
Attachments").<br>

2002-03-20 03:23:00 +03:00
|
|
|
contribution of tests and samples by other parties. Please note that
|
|
|
|
|
these files do not work in the linked location due to js files being shown
|
|
|
|
|
as HTML cross-referenced files, so they must be copied from the current
|
|
|
|
|
mozilla tree to the client's local harddrive or some web server before
|
|
|
|
|
testing them.<br>

To test the services, it is interesting to turn on MOZ_DEBUG=1,
|
|
|
|
|
because even if you do not debug the program, this causes the exchanged
|
|
|
|
|
SOAP messages to be displayed on the standard output if you run from a command
|
|
|
|
|
shell where this is visible.<br>
|
|

<br>
|
|
|
|
|
A SOAP service server has been set up at ray.dsl.xmission.com where
|
|
|
|
|
additional services may be deployed to help test and demo the features
|
|
|
|
|
for scripting SOAP in Mozilla. No home page describes the Apache
|
|
|
|
|
Jakarta server on port 8080 which is the test facility, but this is currently
|
|
|
|
|
used in two tests in the previously-mentioned directory: soapisprimenumber.html
|
|
|
|
|
and soapunscramble.html. Adding services is as easy as writing functions
|
|
|
|
|
in Javascript, Java, or other supported languages and describing the deployment
|
|
|
|
|
in XML. Disclaimer: as this is merely an end-subscriber DSL service,
|
|
|
|
|
if the server becomes too widely published, it may have to be shut down.<br>
