Eclipse WAR with 2 projects?

Question

I am trying to export a WAR file from Eclipse. I have a "Dynamic Web Project". But I need classes created for two other projects, one a plain Java project, the other another web project. So in the Build Config I told it to add the other projects and on the "Order and Export" page I clicked the boxes to export the second and third projects. In runs fine within Eclipse, apparently finds the files from the other projects with no problem. But when I export, only the files from the first project are included in the WAR file.

How do I get Eclipse to include the other projects' files in the WAR? Apparently just adding them to the Build Config and marking for export isn't enough. Is there a problem because one of the other projects is also a web project? Does Eclipse balk at that?

I presume I could make this work by copying the files I need from the other projects to the first. But then any time they are updated, I would have to know that this had happened and copy the new versions. That would be a pain, and I thought that's what Eclipse projects were for, so I could share files between applications.

Edit

Let me clarify that I don't want to deploy 2 WARs. I have a web app written for one project that includes some classes that I want to re-use on another project. What I was trying to do was just pick up those couple of classes in the "real" WAR. I definately don't want to deploy 2 WARs because this might go on the same server as the original project, and I don't want to overwrite the existing WAR of the original project.

Thanks for any help!

You need to add your other project as a Java EE module to your web project. Right click on your web project -> properties -> Java EE module Dependencies. Add the 'other' project to it. Eclipse will include this project in the export.
