Compiling a Java Service

When you save a Java service, Designer automatically compiles the Java service in the Service Development Project and on Integration Server.

Before a Java service can be compiled, keep the following requirements and points in mind:

You must add any additional Java classes that the Java service requires to both the Service Development Project and to Integration Server. For more information, see Adding Classes to the Service Development Project. For more information about adding classes to Integration Server, see information about managing IS packages and how Integration Server stores IS package information in webMethods Integration Server Administrator’s Guide.

Integration Server must have a Java compiler that is the same version as the Java compiler used in the Designer local workspace.

When compiling the Java service locally, Designer uses the default Java compiler settings. You can update these settings by updating the Service Development Project’s Java Compiler properties.

By default, the Service Development Project uses the default JRE that is configured for Designer. You can configure a different JRE using the Service Development Project’s Java Build Path properties and setting a new JRE on the Libraries tab.

Important: You do not need to use the jcode utility to compile and transfer the Java service to Integration Server. The jcode utility is only necessary when you are using an IDE other than Designer. For more information about building Java services using your own IDE, see Building Java Services in Your Own IDE.

1. If the service is not open in the Java service editor, open it by double clicking the Java service in the Package Navigator view.

Problems view for compilation errors from locally compiling the service

If Problems view is not already open, you can open it by selecting Window > Show View > Problems.

To view the line of code that caused the error, double click on the error in the Problems view and Designer shifts focus to the Java service editor, with the cursor positioned at the line of code that caused the error.

Popup window for compilation errors from Integration Server

Designer writes the error messages from the server to the Designer log file, making them visible within the Error Log View.

If you receive errors because the Java compiler cannot be found in Integration Server, ensure you have a Java compiler installed on the same machine as Integration Server and that you have added the location of the Java compiler to the system path.
