Easiest way to add a Library to the Java-Classpath ? [message #73991]

Hi,

I would like to make a few classes of a plugin available for the Java-VM.

Explanation:

I have an Eclipse-Plugin. This library I want to make available during
Eclipse startup has to be in that plugin - there is no other way to
deploy it!

The classes in the library should be basically available directly to the
Java VM. It contains a Swing-LookAndFeel and I set a eclipse.ini system
property which tells the Java-VM to set this as the default
Swing-LookAndFeel!!!

But for that this Swing-LookAndFeel has to be available the moment the
JavaVM starts up!

How is this possible ?

Cheers,
ex.

Put it as an option in the eclipse.ini to pass it in as -D argument to set the look and feel, rather than programatically at run-time.

The OSGi R4 standard defines the notion of bootclasspath extensions.
Basically you can supply a fragment to the system and it will put your
classes on the bootclasspath of the VM as it is started. This part of
the spec is optional and is in fact the only part of the framework spec
that we do NOT implement (no one does as far as I know). The spec is
more to standardize the markup than the mechanism.

Failing that built in support, you can control what happens to the VM by
messing with the -vmargs passed to eclipse.exe (either on the command
line or in eclispe.ini)
