I'm not sure what's wrong with the wsimport, does not tell much about
the problem. As I can tell from the POMs, jaxws-maven-plugin uses XJC
2.1.7 (not 100% sure) which is quite old. Plugins may simply have
compatibility problems. Try running with
-Dcom.sun.tools.xjc.Options.findServices to see how/if plugins are
loaded.
