# Adding Web library projects

Web library projects allow you to associate Java™ projects with "virtual" JAR files in a Web project's WEB-INF/lib directory. You can reference JAR files that exist elsewhere in the Enterprise Application project that contains your Web project, if they are in the Web project's build path, and avoid the need to explicitly copy these JAR files into the project's lib folder before you publish the Web application to a server.

To set up these associations:

1. Right click on a Web project and select Properties from the pop-up menu.
2. Click on Java EE Module Dependencies
3. Set up your associations in the Java EE Module Dependencies window
4. Click OK when you are done.
