Re: Integrating XMLBeans into an Eclipse plugin

[David Jencks]

TCCL == thread context class loader

So, set up your classloaders so cl has the xmlbeans jar and any other 
xmlbeans generated classes you need to reference.
Thread thread = Thread.currentThread();
ClassLoader oldCl = thread.getContextClassLoader();
thread.setContextClassLoader(cl);
try {
    //call xmlbeans compiler methods here
} finally {
   thread.setContextClassLoader(oldCl);
}
Rather than running the ant task inside maven I recommend using the 
maven xmlbeans2 task :-)
Here's a maven dependency for it:

        <dependency>
            <groupId>xmlbeans</groupId>
            <artifactId>xmlbeans-maven-plugin</artifactId>
            <version>2.0.0-beta1</version>
            <type>plugin</type>
        </dependency>

I'm still a little confused about where xmlbeans likes to put the 
source schemas, so suggestions for improvements and clarifications are 
definitely welcome.

thanks

Hi David J,
  I'm a little unfamilair with the terminology here (TCCL ?) but would 
it be possible for you to explain what you did in a bit more detail ?. 
We have the same problem in the Eclipse plugin and in the ant task  
(when run inside maven). One of the guys here is making an Idea plugin 
and it seems to have the same problem !

generated classes I expected to use.  This cl also included xmlbeans
itself.
