Hello,
this is Jersey related, please use users_at_jersey.java.net.
and btw, looks like Jersey is unable to scan you package "com.wgf.ui",
you might want to try set resource class names explicitly, something like:
<init-param>
<param-name>com.sun.jersey.config.property.classnames</param-name>
<param-value>com.wgf.ui.MyResource;com.wgf.ui.AnotherResource</param-value>
</init-param>
Regards,
Pavel
