I run job , i got error message

here is my code

                         IDfWorkflowBuilder workflowBuilder = session.newWorkflowBuilder(new DfId(workflowId));
                        IDfId newWorkflowId = workflowBuilder.initWorkflow();
                       
                        IDfUser objuser = (IDfUser)session.getObject(new DfId(supervisor));
                        //workflowBuilder.getWorkflow().updateSupervisorName(objuser.getUserName());
                        IDfId runId = workflowBuilder.runWorkflow();
                       
                       
                        IDfList startActNames = workflowBuilder.getStartActivityNames();
                        String actName = (String)startActNames.get(0);
                       
                       
                        IDfList startActId = workflowBuilder.getStartActivityIds();
                        IDfId stActId = (IDfId)startActId.get(0);
                       
                        IDfActivity stactivity = (IDfActivity)session.getObject(stActId);
                        int count = stactivity.getPortCount();
                       
                        String inputPortName = "";
                        for(int i=0;i<count;i++){
                            if(stactivity.getPortType(i).equals("INPUT")){
                                inputPortName = stactivity.getPortName(i);
                            }
                           
                        }
                       
                        IDfClient client = DfClient.getLocalClient();
                        IDctmFormService formService = (IDctmFormService)client.newService((com.documentum.xforms.docbase.IDctmFormService.class).getName(), session.getSessionManager());
                       
                        templateId = session.getIdByQualification("dm_xfm_form where definition_state = 2 and object_name = '"+formTemplateName+"'");
                        IDfId formId = formService.createInstance(templateId,outputFormName,outputFolderName,session.getDocbaseName());
                       
                        DfList list = new DfList();
                        list.append(formId);
                       
                        IDfSysObject o = (IDfSysObject)session.getObjectByQualification("dm_xfm_schema WHERE FOLDER('"+formTemplateFolder+"')");
                        IDfId packageId = workflowBuilder.addPackage(actName,inputPortName,"LegalExpire",o.getString("storage_type"),"",false,list);

And here is method to create SessionManager

protected static IDfSessionManager login(String username, String password, String docbase) throws DfException
    {
        // now login
        IDfClient dfClient = DfClient.getLocalClient();
       
        if (dfClient != null)
        {
            IDfLoginInfo li = new DfLoginInfo();
            li.setUser(username);
            li.setPassword(password);
            li.setDomain(null);
           
            IDfSessionManager sessionMgr = dfClient.newSessionManager();
            sessionMgr.setIdentity(docbase, li);
            return sessionMgr;
        }
       
        return null;
    }

Please help me to solve this problem?
