Larry,
I have actually filed a bug for this. See [1]. Vote for it please. I
don't know if there is any better way to solve it, but I faced it for
one of my GlassFish extension bundles and I worked around it like this:
import org.glassfish.internal.api.Globals;
import org.glassfish.internal.api.ClassLoaderHierarchy;
...
private JAXBContext getJAXBContext() throws JAXBException {
// We need to set context class loader to be CommonClassLoader,
otherwise our stupid JAXB implementation
// won't be able to locate the default JAXB context factory class.
final Thread thread = Thread.currentThread();
ClassLoader oldCL = thread.getContextClassLoader();
try {
ClassLoader ccl =
Globals.get(ClassLoaderHierarchy.class).getCommonClassLoader();
thread.setContextClassLoader(ccl);
JAXBContext jc = JAXBContext.newInstance(ObjectFactory.class);
return jc;
} finally {
thread.setContextClassLoader(oldCL);
}
}
You will have to add the following dependency to compile though:
<dependency>
<groupId>org.glassfish.common</groupId>
<artifactId>internal-api</artifactId>
<version>${project.version}</version>
</dependency>
I don't think you can apply this work around in your code - it has too
much dependency on glassfish internals.
Thanks,
Sahoo
