I want to start new instance of a process from workItemHandler of a customize service
task.
To achive this I created Service task in Process 1 and call Process 2 from workItemHandler
class of service using RestFul link
"/gwt-console-server/rs/process/definition/{id}/new_instance".but when I start
Process 1 I am getting Exception
* URL: '
http://localhost:8080/gwt-console-server/rs/process/definition/hello/new_...
http://localhost:8080/gwt-console-server/rs/process/definition/hello/new_...
* Action: 'org.jboss.bpm.console.client.process.StartNewInstanceAction'
* Exception: 'class java.io.IOException'
Request timeout
Please any one can help me to do this intercommunication between two Processes using
Restful link.

change the process id in this code and use the following jars
https://community.jboss.org/servlet/JiveServlet/showImage/2-799005-20364/...
https://community.jboss.org/servlet/JiveServlet/downloadImage/2-799005-20...
Your process should have the process form.
I hope so it will helpfull for you.
Sorry for my english

not working if both process on same machine.
And one more query I have .After starting 2nd process I want my customized respone(i.e
2nd processes data) back in 1st process.By default I am getting json object .How can I get
2nd Process data in response.
Thanks n Regards
