How to expose a jbpm workflow as web service.

[justuser]

Hi,

I have created a sample workflow in jbpm 3.2.6 & using jbpm-console over tomcat 6 & mysql db.

Now as per use case, i need to expose it as a web service so that any third party can invoke it.

I googled a lot but of little help.

Does jbpm support this feature in 3.2 version?

If yes, How can i do it?

Any help will be highly appreciated.

Hi All,

You can use the following code to trigger a workflow in java.

/**
     * Method to trigger workflow dynamically.
     */
    public void exposeWorkflowAsWebService(){
        JbpmContext jbpmContext = null;
        try{
            System.out.println("Invoking a workflow");
            jbpmContext = JbpmConfiguration.getInstance().createJbpmContext();
            ProcessInstance processInstance = jbpmContext.newProcessInstance("NotificationWorkflow");
            while (!processInstance.isTerminatedImplicitly()) {
                processInstance.signal();           
            }
        }catch (Exception e) {
            System.out.println("Error while invoking workflow : "+e.getMessage());
            e.printStackTrace();
        }finally {       
            System.out.println("Finally closing jbpmContext.");
            jbpmContext.close();   
            }
    } 

This java code can be exposed as web service & used as needed.
