Chapter 42. Recommendations for Transformations Developers
Add external libraries to app-server classpath
Connections (JDBC/JMS) may require third-party libraries. We strongly recommend adding these libraries to the app-server classpath.
CloverDX allows you to specify these libraries directly in a graph definition
so that CloverDX can load these libraries dynamically.
However, external libraries may cause memory leak,
java.lang.OutOfMemoryError: PermGen space, in this case.
In addition, app-servers should have the JMS API on their classpath – and the third-party libraries often bundle this API as well. So it may result in class loading conflicts if these libraries are not loaded by the same classloader.
Another graphs executed by RunGraph component may be executed only in the same JVM instance
In the Server environment, all graphs are executed in the same VM instance. The attribute same instance of the RunGraph component cannot be set to false.
