Hello,
I've got a "little" Problem in how using the struts select - tag correctly.
I'm new to Struts and have read the mails correspondig to the select-tag in
this mailing-list, but i'm not able to run my select tag.
Scenario:
In my action class a list of planningperiods is generated. the select - tag
in the following jsp should be filled with the ids of these periods. I wrote
an helper class containing only three attributes (planninperiodid,
begindate, enddate), with the correct getter-/setter-Methods.....
here is the code of the helper class, action class, the jsp containing the
select tag and the error code:
<-------------- helper class code --------------------->
package actions.helper;
....
public class PlanningPeriodHelper extends PlanningPeriod {
private String planningperiodid;
private String begindate;
private String enddate;
public PlanningPeriodHelper() {
}
public PlanningPeriodHelper(String ppid, String begindate, String enddate)
{
this.planningperiodid = ppid;
this.begindate = begindate;
this.enddate = enddate;
}
public void setPlanningperiodid(String ppid)
{
this.planningperiodid = ppid;
}
public void setBegindate(String bd)
{
this.begindate = bd;
}
public void setEeginddate(String ed)
{
this.enddate = ed;
}
public String getPlanningperiodid()
{
return super.getPlanningPeriodID();
}
public String getBegindate()
{
return begindate;
}
public String getEnddate()
{
return enddate;
}
public static List getAllPlanningperiods()
{
Iterator _pps = PlanningPeriod.getPlanningPeriods().iterator();
List _pplist = new ArrayList();
while (_pps.hasNext())
{
PlanningPeriod next = (PlanningPeriod)_pps.next();
_pplist.add(new PlanningPeriodHelper(next.getPlanningPeriodID(),
new
Long(next.getBeginDate()).toString(),
new
Long(next.getEndDate()).toString()));
}
return _pplist;
}
}
<-------------- end ---------------------------------->
<-------------- action class ------------------------->
public class InitSelectAction extends Action {
public ActionForward perform (ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws
IOException, ServletException
{
List _pplist = PlanningPeriodHelper.getAllPlanningperiods();
request.setAttribute("pplist",_pplist);
request.setAttribute("begindate", new Long(1234).toString());
request.setAttribute("enddate", new Long(1235).toString());
return mapping.findForward("init");
}
}
<-------------- end ---------------------------------->
<-------------- jsp ---------------------------------->
<body bgcolor="#FFFFFF" text="#000000">
<html:form action="selectPP.do">
<table width="400" border="1">
