Setting a Project Classpath 

Use

The project classpath is crucial for any J2EE component in a project. It must point to the JAR or folder where the packages of the components and the classes that they use are located. You can set more than one classpath in a list. The position of a folder or a Java class in the classpath list is important because a classpath is searched for in the classpath list from top to the bottom and the first suitable classpath is used.

Procedure

       1.      Choose Project → Options. The Project Options dialog window appears.

       2.      Choose the Classpath tab. It lists the available classpaths. You can add, remove and rearrange them.

       3.      Manage a classpath or a classpath variable.

       4.      To rearrange the position of an available classpath, use the Move Up and Move Down buttons.

       5.      To delete a classpath directory from the list, choose it and click the Delete button.

       6.      Click the OK button to confirm your changes.
