Re: [ jEdit-devel ] JarClassLoader for Plugins

[<Ste...@lr...>]

This is not a jEdit problem, just normal classloader operation.

jEdit plugins are loaded via a custom classloader
(org.gjt.sp.jedit.JARClassLoader). The JVM requires that if an object requests
that a class be loaded, that it be done using the same classloader that loaded
the referencing object. Therefore, the JVM  expects the plugin classloader to
load those classes, not the system classloader. The plugin classloader was not
designed to load classes off the CLASSPATH.

I'll echo Dirk's suggestion: all resources required by a plugin which are not
already in jEdit should be in the plugin's JAR, or at least should all be in jar
files in jEdit's "jars" directory.

I'm developing a Plugin which supports an RMI FileSystem.  The Plugin references
classes in a separate JAR file.  When JEdit loads the Plugins, my plugin doesn't
load because it can't find the separate JAR, although it is within the CLASSPATH
directive.

To remedy the problem short-term, I included all of the files in the separate
JAR file into my Plugin JAR file.  However, this doesn's seem to be very
scalable.

Am I missing something?  or is this a limitation of JEdit's Plugin capability?

Thanks,
Kyley
