Hello Lakshmi,

I do somthing like that and for me it works good:

Start the process with a own handler:
+GuiProcessHandler handler = new GuiProcessHandler();+
+Map<String, Object> params = new HashMap<String, Object>();+
+params.put("handler", handler);+

+// start a new process instance+
+ksession.startProcess(processName, params);+

+...handler.getOutputs();+

A workitem for imageoutput:
+public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {    + 
+   BufferedImage image ...+
+   GuiProcessHandler handler = (GuiProcessHandler) workItem.getParameter("handler");+
+   handler.addImage(image);+
+}+

Please note BufferedImage is not serializable, so you must convert it to a byte array.

Good luck!
