Hi Angel,
What version of Jersey are you using?
I think this might be a class loading issue from within the OpenOffice
environment. Jersey loads classes declared in META-INF/services files.
From the log output it certainly finds those services files but it
cannot find the classes declared in those files because
ClassNotFoundException is thrown.
Jersey uses the thread context class loader to load such classes.
Perhaps you can do the following:
Thread
.currentThread
().setContextClassLoader(this.getClass().getClassLoader());
Paul.
