I am getting:

javax.servlet.ServletException: Cannot find bean DateRange in any scope


My Action Class (ShowKalendarList.java) is:
---------------------------------------------------

public ActionForward execute( ActionMapping mapping,
                                                    ActionForm form,
                                                  HttpServletRequest request,
                                                  HttpServletResponse response) throws Exception {
            
            
            try {
                  Context context = new InitialContext();
                  ListSessionHome home = (ListSessionHome)context.lookup(ListSessionHome.JNDI_NAME);
                  ListSession local = home.create();
                  
                  PeriodeSessionHome periodeSessionHome = (PeriodeSessionHome)context.lookup(PeriodeSessionHome.JNDI_NAME);
                  PeriodeSession periodeSession = periodeSessionHome.create();
                                          
                  System.out.println("------------------");
                  
                  GregorianCalendar from = new GregorianCalendar();
                  from.set(2003,9,20,0,0,0);
                  GregorianCalendar to = new GregorianCalendar();
                  to.set(2003,9,23,0,0,0);
                  
                  System.out.println(from.getTime());
                  System.out.println(to.getTime());
                  
                  /* set it in the request */
                  request.setAttribute("DateRange", periodeSession.getPeriodeByDateRange(from.getTime(), to.getTime()));
                  
            }
            catch (NamingException e) {
                  e.printStackTrace();
            }
            catch (CreateException e) {
                  e.printStackTrace();
            }      
            
            
            return mapping.findForward("Default");
      }


and In my show_kalendar_list.jsp, I have:
--------------------------------------------------

      <logic:iterate name="DateRange" id="Date">
                              <td> <bean:write name="Date" property="label" /> </td>
                        </logic:iterate>


In my Struts-config.xml, I have:
--------------------------------------

 <action path="/ShowKalendarList" type="de.grassgmbh.kalendartool.action.ShowKalendarList">
         <forward name="Default" path="/jsp/manage_list/show_kalendar_list.jsp" />
      </action>

Thanks.

What happens if you add the DateRange in the session? Can you still not retrieve it in the next page?

I assume it does print out your debug (so the action is running)?

With session? Try this:

/* set it in the session */
HttpSession session = request.getSession(false);
session.setAttrigute("DateRange", periodeSession.getPeriodeByDateRange(from.getTime(), to.getTime()));

and in your show_kalendar_list.jsp, do:

Object o = session.getAttribute("DateRange");
System.out.println(o);

Tell us if "o" is null.

sorry...'ListView' is another bean. I actually get:

13:02:47,210 ERROR [Engine] StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception
javax.servlet.jsp.JspException: Cannot find bean DateRange in any scope

and so on.

If action is not running you cannot pass the beans around unless you do it from somewhere else.

You are going to "ShowKalendarList.do" aren't you?  Not straight to the jsp?

javax.servlet.ServletException: No getter method for property  of bean DateRange

            while(calendar.getTime().before(to) || calendar.getTime().equals(to)){
                  
                  PeriodeView periodeView = new PeriodeView();
                  
                  /* WS 26.08.2004
                   * Fill the periode object
                   */
                  calendarTemp.setTime(calendar.getTime());
                  calendarTemp.add(Calendar.MINUTE, 1440);
                  periodeView.setDateFrom(calendar.getTime());
                  periodeView.setDateTo(calendarTemp.getTime());
                  periodeView.setLabel(df.format(calendar.getTime()));
                  
                  arrayList.add(periodeView);
                                    
                  calendar.add(Calendar.DATE, 1);
            }
            
            return (PeriodeView[])arrayList.toArray(new PeriodeView[0]);
      }
      
 ...............................

and my PeriodeView contains all the getter, setter for the variables.

But, i think the problem might be different, as it worked yesterday!

>> What have you changed since yesterday?

yes, i got it. I have seperate 'Struts' and EJB projects. The mistake was: I didnt made Project-References for them.

I dont know when i will stop wasting time for these silly errors.

Anyhow, i learnt something from you in this Q. Thanks for your patience.
