Input parameters from process

Question

Hi,
I have a scenario where the user enters the process id as the input and once he submits it
I have to retrieve the input parameters of that process
Is it possible to get the input parameters using the GP API
Please give me a lead on how to achieve this
Thanks

Hi
You can achieve this using wd api, you need to create the webdynpro application
IGPProcess process = null;
     String message = "";
     String processName = "Cab Booking Process";
     try {
           IWDClientUser wdUser = WDClientUser.getCurrentUser();
           IUser user = wdUser.getSAPUser();
          // wdComponentAPI.getMessageManager().reportSuccess("current user is : " + user.getFirstName());
           IGPUserContext userContext = GPContextFactory.getContextManager().createUserContext(user);//, user.getLocale());
           process =GPProcessFactory.getDesigntimeManager().getActiveTemplate("7031AF6B877511DCBBB60016353AC84F",userContext);
           IGPRuntimeManager rtm = GPProcessFactory.getRuntimeManager();
           IGPProcessRoleInstanceList roles = rtm.createProcessRoleInstanceList();
           int rolenum = process.getRoleInfoCount();
           //wdComponentAPI.getMessageManager().reportSuccess("dyn user is : " + user.getFirstName());
           IGPProcessRoleInstance roleInstance=null;
           IGPStructure params = null;
          // wdComponentAPI.getMessageManager().reportSuccess("Title is "+ process.getTitle());
//           if (process.getTitle().equals("Cab Booking Process"))
//               wdComponentAPI.getMessageManager().reportSuccess("get process instance "user.getFirstName()"  "user.getLastName()rtm.getRunningInstances(0, new Date(2007,1,1), new Date(System.currentTimeMillis()), user));
           try {
                params = GPStructureFactory.getStructure(process.getInputParameters());
                     if (process.getTitle().equals("Cab Booking Process")) {
                         params.setAttributeValue("RequestId.4",wdContext.currentContextElement().getRequestId());
                         params.setAttributeValue("EmployeeId.4",wdContext.currentContextElement().getEmployeeId());
                         params.setAttributeValue("ApproverId.4",wdContext.nodeZhr_Emp_Sup_Info_Input().nodeOutput_Approver().node_Output().current_OutputElement().getUser_Id());
                         params.setAttributeValue("ApproverName.4",wdContext.nodeZhr_Emp_Sup_Info_Input().nodeOutput_Approver().node_Output().current_OutputElement().getName());
                         params.setAttributeValue("Name.4",wdContext.currentOrg_AssignmentElement().getName());
                         params.setAttributeValue("Grade.4",wdContext.currentOrg_AssignmentElement().getEsubgroup());
                         params.setAttributeValue("Department.4",wdContext.currentOrg_AssignmentElement().getOrgtxt());
                         params.setAttributeValue("PersonalArea.4",wdContext.currentContextElement().getPersonalSubAreaText());
                         params.setAttributeValue("CostCenter.4",wdContext.currentContextElement().getCostCenter_GuestText());
                         //params.setAttributeValue("ActionName.4","Test Cab Request From Reddy");
                         if(wdContext.currentContextElement().getResultState().equalsIgnoreCase("Submit")){
                              //setting the Action name dynamically(UWL Task Name)
                              wdContext.currentContextElement().setActionName("Approve Cab Request Of " + wdContext.currentOrg_AssignmentElement().getName());
                              params.setAttributeValue("ActionName.4", wdContext.currentContextElement().getActionName());
                              wdComponentAPI.getMessageManager().reportSuccess("Your Request Form has been sumbited for the Approval.");
                              message = "Your Request has been sumbited for the Approval.\n\tRequest ID : " + wdContext.currentContextElement().getRequestId();
                         } else {
                              //setting the Action name dynamically(UWL Task Name)
                              wdContext.currentContextElement().setActionName("Cab Booking Request from " + wdContext.currentOrg_AssignmentElement().getName());
                              params.setAttributeValue("ActionName.4", wdContext.currentContextElement().getActionName());
                              params.setAttributeValue("Extra.4",getTravelDeskPortalId());//Travel Desk Id
                              wdComponentAPI.getMessageManager().reportSuccess("Your Request has been sent to Travel Desk.");
                              message = "Your Request has been sumbited to the Travel Desk.\n\tRequest ID : " + wdContext.currentContextElement().getRequestId();
                }catch(Exception e){
                     wdComponentAPI.getMessageManager().reportSuccess("Exception in Parameter Set "+e);
           IGPProcessInstance prInstance = rtm.startProcess(process,processName,"This process has been started using the GP public API",user,roles,params,user);
           catch(Exception e){
                wdComponentAPI.getMessageManager().reportSuccess("Exception Main Try Block "+e);
           try{
           catch (Exception e){
               wdComponentAPI.getMessageManager().reportSuccess("Error in Calling Complete" +e.getMessage());
