EclipseClassLoader info [message #173493]

Does anyone know anything about the "EclipseClassLoader" class. A plugin
I am developing dies in the various release candidates, apparently because
the class loader returned by Plugin.class.getClassLoader() is now an
EclipseClassLoader instead of a URLClassLoader.

For whatever the reasons my getResource() calls are returning zilch and my
attempts to cast the returned ClassLoader to an EclipseClassLoader die
from some ambiguous red event message.

Organize imports finds the EclipseClassLoader import but things die in the
debug/runtime workbench.

Any thoughts???

Why do you need to cast it? That is an internal class and can change at
any time.

Hi Michael,

we recently switched from JDT to PDE (Eclipse RCP) and faced some issues,
which might be similar to yours. We highly recommend pp.54 and 55 of
"Contributing to Eclipse" which explain very clearly how Eclipse finds
classes at runtime.

The problem actually is not with the type of class loader but with the
class loader class paths and with the hierarchy of the class loaders. One
possible reason for your problem is that you might be searching classes or
resources located on the system class path. As the system class loader is
not part of the Eclipse hierarchy of class loaders, you'll never find them.

Hope this might be pointing you in the right direction.

Cheers
Thorsten
