The External Java Library Node

Use the External Java Library node () to import compiled Java libraries that you want to include in a method. The Java libraries (JAR files) can be created with any third-party Java development tool. To add a new External Java Library node, right-click the Libraries node () and choose External Java Library or click the External Java Library button on the ribbon toolbar. Enter a label to display in the Label field.

The Settings window for an External Java Library node contains the following section:

Import Library

In the Filename field, enter the name of the Java library file that you want to import, or click Browse to locate and choose a Java library file (JAR file). Then click Import to import the library into the application. During the import, the following happens:

•	The JAR file is copied into the application. When you save the application, it contains a copy of the entire JAR file.

•	Import statements for packages declared in the JAR file are added to the source code of all existing and future methods and utility classes in the application.

•	All Java code in the application is recompiled, with the added JAR file on the class path.

•	When compiling code in the future, the JAR file is on the class path.

To use an updated version of the library, click the Import button again. Because the application contains a copy of the library, it is not sufficient to just update the original JAR file.

If you delete the External Java Library node, the program updates all Java source code to exclude imports defined by the JAR file and recompiles all Java code in the application.
