Jibx actually modifies classes to create new class files with Jibx code in
them. As far as I know, there is no way to pull in dependencies from something
like an artifact repository because those dependencies are a reference, and the
files don't actually reside in the project. Though this is a bit of a hack,
we've been able to get around this by running an Ant script (which it appears
you are using) that copies *.class files from a jar to target/classes using the
Ant unzip command:
<unzip src="<your repo jar>" dest="<your classes folder>">
<patternset>
<include name="**/*.class"/>
<exclude name="**/*.java"/>
</patternset>
</unzip>
I don't think that's your problem though. Jibx would have thrown a
ClassNotFoundException, not a NPE. Did you debug through the stack trace?
Thanks,
Drew

Subject: [jibx-users] NullPointerException when running binding compiler
Hi -
I'm trying to compile my object which has a superclass that implements
interfaces. I've tried running both the command as well as Ant options but the
error remains the same. Here is the stack trace

Since I'm new to JIBX I don't have an idea what exactly is going wrong. Another
thing is that JIBX fails to find classes that are included as dependent
projects when I run the compile option.
