Hi All,

        I am using the Maven2-JAXB plugin and am facing a problem. When I
try to generate the sources from the XSD. I get the following error.
[FATAL ERROR] com.sun.tools.xjc.maven2.XJCMojo#execute() caused a linkage
error (java.lang.NoClassDefFoundError) and may be out-of-date. Check the
realms:

I'm not sure why this error happens and how it is corrected. Any help in
this regard would be much appreciated.!
