Details

You can include classes from other compiled JAR files in your application. To include these files, save the JAR file in a new project in the same workspace as your application. Make this new project a library application and make your application dependent on this library. You can then import all of its classes. The following steps make up this procedure.

To create a new project

  1. Open the workspace that contains your application's project.
  2. Create a new project.

To add a compiled JAR file to the project

  1. In the navigation pane, select the project.
  2. On the Build menu, select Project > Add File to Project.
  3. Select the appropriate JAR file and click Open.

To make the project a library

  1. In the navigation pane, select the project.
  2. Right-click and select Properties. The <Project name> Class Properties window appears.
  3. Click the Application tab.
  4. From the Project Type drop-down list, select Library.

To compile the project

  1. In the navigation pane, select the project.
  2. Right-click and click Build Project.

To make the project dependent on the new library

  1. In the navigation pane, select the project.
  2. Right-click and click Project Dependencies. The Class depends on <Project name:> window appears.
  3. Select the <Project name> check box.

Your application can now import the classes in this JAR file with the import “xxx.yyy.*” command.
