If the Software AG Runtime is running on a UNIX or Linux platform and you want to use the print feature, you must set Java AWT to be set to headless mode. You must set headless mode, for example, if you want to perform instance printing or preview BIRT reports.

To set Java AWT to headless mode, add the following Java system property to the custom_wrapper.conf file in <SuiteInstallDir>/profiles/CTP/ folder on the machine where the Software AG Runtime is installed. For information about setting Java system properties in custom_wrapper.conf, see the webMethods cross-product document Working with the webMethods Product Suite and the Java Service Wrapper .
