You open this dialog box by right-clicking any and choosing Properties. The Libraries page lets you set up the libraries that the project contains on its classpath.
Java Platform. You can use the Java Platform drop-down list to set the specific JDK installation that the IDE uses to compile and run your project. The IDE adds the selected platform's libraries to the classpath and uses the platform's executables (such as javac and java) to run and build the project. The default platform for all projects is the platform on which the IDE is running. You can register additional platforms and attach Javadoc and source files to a platform by clicking Manage Platforms.
Libraries Folder. To make it easier to share libraries among different users and projects, you can set a folder to hold those libraries (or references to those libraries). You can create a new folder or specify an existing folder that already contains copies of the libraries on which your project depends.
To specify the folder, click Browse. If there is already a libraries folder, a file chooser opens. If there is not a libraries folder, the New Libraries wizard opens. In the New Libraries wizard, you set a libraries folder and then specify how to reference each library. The simplest case is to have the libraries copied to that folder. You can also refer to the libraries in their existing location (with a relative path or an absolute path). If you have specified an existing folder, you also have the option of using copies of libraries that are already in that folder instead of the copies that are contained in the IDE's Library Manager.
Each standard EJB module project maintains a separate classpath for compilation, compiling tests, and running tests. Use the buttons on the right of the dialog box to add, remove, and change the order of classpath elements. You can add any of the following:
