Dennis Sosnoski resolved JIBX-289.
----------------------------------
Assignee: Dennis Sosnoski
Resolution: Fixed
Fix Version/s: JiBX 1.2.2
So if I understand this correctly, the problem occurs when trying to compile a
binding using precompiled bindings with maven. The code which loads the
precompiled binding information uses the ClassFile classloader, which only
works off URLs and ignores the maven Classworks classloader.
The code has been changed for the 1.2.2 release to have the ClassFile
classloader use ClassFile.class.getClassLoader() as the parent classloader, so
based on your tests this should take care of the problem.

> Key: JIBX-289
> URL: http://jira.codehaus.org/browse/JIBX-289
> Project: JiBX
> Issue Type: Bug
> Components: core
> Affects Versions: JiBX 1.2.1
> Reporter: Karel A Sague
> Assignee: Dennis Sosnoski
> Fix For: JiBX 1.2.2
>
>
> I'm working with maven 2.0.9 and JiBX 1.2.1.
> I've reported on the error previously at
> http://www.mail-archive.com/jibx-users%40lists.sourceforge.net/msg03932.html
> It's being generated at BindingDirectory.getFactory(String bname,
> String pack, ClassLoader loader), line 273
> "if (result instanceof IBindingFactory) {"
> "result" is loaded via a class loader initialized in
> "org.jibx.binding.classes.ClassFile.setPaths(String[] paths)", line
> 2048:
> s_directLoader = new URLClassLoader(urls);
> This classloader's parent classloader is the system class loader.
> However IBindingFactory is loaded by RealmClassLoader which is part of
> the Classworks clsas loading framework used by Maven.
> There are two fixes that in both cases should be considered according
> to the use of the binding compiler. Both set the parent class loader to
> the UrlClassLoader that loads the bindings:
> s_directLoader = new
> URLClassLoader(urls,ClassFile.getClass().getClassLoader());
> or
> s_directLoader = new URLClassLoader(urls,
> Thread.currentThread().getContextClassLoader());
> In both cases "result" which is the binding factory generated for the
> precompiled project, is loaded via the parent class loaders which
> s_directLoader will delegate to, thus, the "result instanceof
> IBindingFactory" succeeds.
> I tested both solutions using the Maven JiBX plugin 1.2.1, Maven Antrun
> plugin and invoking directly the compiler via the command line
> successfully.
