JAX-WS webservice that uses Custom POJO as parameter and return value from a separate project

I am attempting to implement a Web Service that uses a POJO as a return value and a parameter as well. Whenver I do that though, I get the following Exception... 

Exception while deploying the app [EnterpriseLoggingPoCEAR] : Invalid ejb jar [EnterpriseLoggingPoC.jar]: it contains zero ejb.

Is there something I should be annotating my POJO with? The POJO was included in the Build path... I know in .net you have to annotate your class with [DataContract]... Do I have to do the same for JAX-WS pojo's?

One thing that I neglected to mention was that the POJO was in a package and a project that was not part of the Web Service project. Once I moved the package into my project the error cleared up and I was able to deploy the project locally. Now I thought I added my project to the build path of the other web service project. But it would still throw that exception. Any ideas?

eclipse can help with references between projects for to reuse classes and libraries. For example, if you have an EAR project that contains a Web module and a EJB module, you can share between them domain classes (e.g. with @Entity annotation) or interfaces (with @Remote o @Local annotation).

If you check the project properties of EnterpriseLoggingPoCEAR, you could see something similar to:

enter image description here

In the images, the project ExampleModel is a typical Java project. This project has a additional facet: Utility Module. This facet is add automatically when you using the Add... button in the EAR properties.

enter image description here

The error that you mention is because you add a EJB module without any EJB.

Also instead of reference to another project, you can add a jar in the lib folder of EAR.

By the way, if you reference the project, this is also done automatically.
