How to return UIMA Ruta's output from a server?

Question

I want to run Ruta scripts on a separate server and return the output for further processing (in Java).

The only way that I know to trigger a Ruta script is by calling the engine.process(cas) method from a Java maven project. But it doesn't generate an xmi file which could be sent back to the client (i.e., Java server) for further processing. Neither can I return the CAS object to the client (if I'm right).

How can I achieve it?

• How to return CAS from server to client? (OR)
• How to generate xmi file while running Ruta from Java code ?

Tell me a better way if any.

Answer 1

Just a comment to the second bullit point in your question:

In the java code when running engine.process(), you could simply use the CasIOUtils to write the CAS to some (file/byte) outputstream in the XMI format or in some other format.
