Service Composition with Activiti

engr_arko

Hello Everyone,
I am a newbie in BPMN with Java knowledge. In order to learn service composition using Activiti, I want to test following task:

There is a webservice that takes string in request and responses a string parameter as well. Now I want to create a webservice using Activiti that invoke this webservice but enable a new interface.

Please suggest me with any kind of tutorial or instruction link.

Thank You

Could you explain what you mean by this?

There is no tutorial with web services on itself, you will have to read the Userguide and applu what is written there to webservices.

Hello,
Thank you for your reply!
Explanation about this: "Now I want to create a webservice using Activiti that invoke this webservice but enable a new interface."
I thought like BPEL engines it is also possible to create a WSDL interface for service composition in BPMN. But I figured out that with activiti maybe it is not possible without java code.

Yes tried to understand user guide, but it seems not straight forward for newbies like me

Indeed, in BPEL a process definition is a webservice on itself.
This is not the case for Activiti and BPMN 2.0. However, there is generic REST api (http://activiti.org/userguide/index.html#N12F85) you can use to interact with all processes in a similar way.
