I am trying to compile the JAXB 2.0 sample provided with XFire 1.0 and am running into a problem that I can't seem to resolve. I have tried compiling with maven 2.0.1 and 2.0.2, then fell back to 1.0.2 just to make sure. But in any case, I keep encountering the following error that I have not been able to resolve; I have included the jaxb-xjc-2.0-ea3.jar into the ant classpath in every manner that i can think of, including modifying the maven.xml ant jaxb.classpath definition but to no avail. I am ready to tear my hair out over this. Any idea how to resolve this issue? If this is not the appropriate place to seek help for this, my apologies in advance.
