(3) jbpm websale code learning: Home. jsp (Startup Process)

1) use the following method to get the latest Process Definition

Jbpmcontext. getcurrentjbpmcontext (). getgraphsession (). findlatestprocessdefinitions ();

2) the above method returns a list of process definitions, which are displayed on the page.

For example, the method to display the name of the startup node is:

Processdefinition. gettaskmgmtdefinition (). getstarttask (). getname ();

3) The process definition ID is passed on JSP. In servlet, processdefinition is obtained using the following method:

Processdefinition = graphsession. loadprocessdefinition (processdefinitionid );
4) Complete the Start Node:

Processinstance = new processinstance (processdefinition );

// Create a new taskinstance for the start task
Taskinstance = processinstance. gettaskmgmtinstance (). createstarttaskinstance ();

// Save the process instance along with the task instance
Jbpmcontext. Save (processinstance );
