    call jbpm workflow from jboss portal

    pedro costa Apprentice

      It's possible to create a jbpm object from a portlet?

      In the method doView from my file, i've created an jbpm object. Although, i get an exception when i run the code. Here is the file and the exception:

      import java.io.*;
      import javax.portlet.*;
      //import com.sample.WorkFlow;
      
      public class Registo extends GenericPortlet {
      
       public WorkFlow workflow;
       String filename = "simple.par/processdefinition.xml";
      
       public static final boolean DEBUG = true;
      
       public void doView(RenderRequest request, RenderResponse response)
       throws PortletException, IOException
       {
       response.setContentType("text/html");
      
       String jspName = getPortletConfig().getInitParameter("jspView");
       PortletRequestDispatcher rd = getPortletContext().getRequestDispatcher("/WEB-INF/jsp/RegistoOcorrencia.jsp");
       rd.include(request, response);
      
       if(DEBUG)
       {
       System.out.println("xxxxxxxxxxxxxxxxxxxxxxxxx");
       System.out.println("JANELA 1");
       System.out.println(jspName);
       System.out.println("xxxxxxxxxxxxxxxxxxxxxxxxx");
       }
      
       workflow = new WorkFlow(filename);
       // Realiza o primeiro estado
       //workflow.RegistoOcorrenciaTask(workflow.getTaskInstance());
       }
      }
