EJB Module Deployment warning

Hi to all,

I have implemented with success a custom EJB Module, but when I deploy it, I receive a warning message of this type:

...Reason: it has hard reference to resource library_xyz with type service, which is not active on the server.

In this module, I reference to a custom java library "library_xyz" that, there isn't on the XI Integration Server. is this the problem? If Yes, how can I solve it?

Can anyone help me?

Thanks to all.
