The action Handlers for the jBpm version:
| package test.jpdl.test;
|
| import org.jbpm.graph.def.ActionHandler;
| import org.jbpm.graph.exe.ExecutionContext;
|
| public class MyActionHandler implements ActionHandler {
|
| private String mensaje = null;
|
| public void setMensaje(String mensaje) {
| this.mensaje = mensaje;
| }
|
| public void execute(ExecutionContext executionContext) throws Exception {
| executionContext.leaveNode();
| }
|
| }
|
And needed imports.
You should see that this is a fairly easy example, as those posted in Tom`s blog, where it stated "awesome performance"

[JBossWS] - Problem in passing/returning objects over dynamic web servic
by rashmi_yes
Hi Friends,
I am beginner in java web service.
Here is the problem I am facing when I pass/return user defined objects to remote web service method using dynamic we service call.
The client can call the remote web service method in 2 ways.
1. By generating client stubs using WSDL file
- In this case, I am able to pass/return the user defined objects to remote method without any issue only when the server side web services are deployed in any server(jboss)
- But in java 1.6 & above, the web services can be deployed without server using endpoint. In this case, I am not able to pass/return objects over web service calls.
2. Without generating client stubs (dynamic web service call)
- This will establish a connection at run time using the given WSDL file (I have attached the document). I have to form an XML(This will contain API name, arguments) string as input at run time
- In this case, it allows only string as argument while passing & returning.
Please let me know if you can help me on this.
Regards,
pani
