Launch Workflow from OAF Page

Using class oracle.apps.fnd.framework.webui.OANavigation provided by Oracle for Workflow API, you can launch workflow directly from OAF Page.  There are two ways to launch workflow :

1.  Oracle PL/SQL API (wf_engine)
2.  Java Wrappers

we shall launch a workflow from OAF page.

1.  Create a submit button and name the partial event as "launchWF"
2.  Write below java procedure to invoke workflow

import oracle.apps.fnd.framework.webui.OANavigation;

    public void launchWF(OAPageContext pageContext)
    {
        String PItemType = "XXTEST";
        String PProcess = "XXTEST_PROCESS";
        String PItemKey = "SEQUENCE VALUE";  // This can be a random item key generated
   
        OANavigation wf = new OANavigation();
   
        // Now create Workflow Process
        wf.createProcess(pageContext, PItemType, PProcess, PItemKey);
   
        // Set Employee number
        wf.setItemAttrText(pageContext, PItemType, PItemKey,"EMPLOYEE_ID", "101");
   
        // Start Workflow Process
        wf.startProcess(pageContext, PItemType, PProcess, PItemKey);
    }


3.  Call the above procedure in ProcessFormRequest Method

    public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
    {
    super.processFormRequest(pageContext, webBean);
    if ("launchWF".equals(pageContext.getParameter(EVENT_PARAM)))
      {
        launchWF(pageContext);
      }
    }
