Create a new ejb or j2ee project and in the 
project explorer, the nodes called
Web Services or Source Packages dont come from
bundle file.

These words are in some bundle files, but in this
case, the value is either not in the bundle file,
or the code does not have the localized strings
to be shown.

Also, please check this module's other strings
to make sure all that should be in bundle file
are in these files and that, once in the files,
they are shown as per locale.
