As there were several questions about how I solved the classloader issue
attached you will find the specialized classloaderfactory. If you use
this workaround don't forget to set the property "urlClassLoaderFactory".

/**
* Custom <code>ClassLoaderFactory</code> for xmlBlaster. This implementation
* takes care of ClassCastExceptions in the default
* <code>StandaloneClassLoaderFactory</code>. It assumes that the current
* classloader is an instance of <code>URLClassLoader</code> but it can be an
* <code>EclipseClassLoader</code> or something else. If the default implemenation fails a new
* delegating <code>URLCLassLoader</code> will be returned to the callers. To use this implementation set
* xmlBlaster property <i>urlClassLoaderFactory</i>.
