Download the latest MRJ
SDK (MRJSDK 2.1 or later). Run the installer, which will
create a folder at the root of your system volume, called "MRJ SDK
2.1." Copy the CIncludes and Libraries folders to the "MRJSDK"
folder in mozilla/plugin/oji/MRJ.
Open the project mozilla/plugin/oji/MRJ/plugin/MRJInABox.mcp.
To build the plugin for 4.X browsers, build the "MRJInABox (4.X)"
target. To build for 5.X, build the "MRJInABox" target.
Build the project mozilla/js/macbuild/LiveConnectClasses.mcp,
and make an alias to the file liveconnect.jar in
mozilla/plugin/oji/MRJ/plugin.
Build the project
mozilla/plugin/oji/MRJ/testing/ConsoleApplet.mcp.
Finally, build the "MRJPlugin.jar" target in
MRJInABox.mcp.
Well that's it. You should now have a working build of the
MRJ plugin.
