Passing parameters from 1 jsp to another

Question

1. Passing String parameter P2 from Filter.jsp to POLGENMA106.jsp thro'
<instance of NavigatorBar>.setTargetUrl
("POLGENMA106.jsp?P2=<%=strTitle%>")
2. Problem faced :
Value is not passed properly.
3. Reason :
When I press Next record in the NavigatorBar,
the string "POLGENMA106.jsp?P2<%=strTitle%>" gets appended with
"?<View name>_NAVIGATE=NEXT" internally instead of "&<View name>_NAVIGATE=NEXT" assuming that we r not passing any paramters.
Is there any method by which we can pass paramters explicitly after instantiating NavigatorBar bean.
4. Code in Filter.jsp:-
<% strTitle = request.getParameter("P2"); %>
<center><h2><%=strTitle%></h2></center>
<jsp:useBean id="RowQuery" class="oracle.jbo.html.databeans.RowsetNavigator" scope="request">
<%
Object[] params = new Object[1]; params[0] = strVSCode;
RowQuery.initialize(application, session , request, response, out, "pol_PMode_Pol_PModeModule.
ComVsStaticValueView1"); RowQuery.setReleaseApplicationResources
(true);
RowQuery.getRowSet().getViewObject().setWhereClauseParams(params);
RowQuery.getRowSet().getViewObject().executeQuery();
RowQuery.getRowSet().first();
%>
</jsp:useBean>
<jsp:useBean class="oracle.jbo.html.databeans.NavigatorBar" id="tb" scope="request" />
<%
tb.setTargetUrl("POLGENMA106.jsp?P2=<%=strTitle%>");
tb.initialize(application,session, request,response,out,"pol_PMode_Pol_PModeModule.ComVsStaticValueView1");
String sImageBase = (String)session.getValue("ImageBase");
tb.getContainer().setImageBase(sImageBase);
tb.getContainer().addSeparator(sImageBase + "/FNDIWDVD.gif");
tb.getContainer().addButton(sImageBase + "/query.gif" , "ComVsStaticValueView1_Query.jsp", "Go to Query Form");
tb.getContainer().addButton(sImageBase + "/browse.gif" , "ComVsStaticValueView1_Browse.jsp", "Go to Browse Form");
tb.getContainer().addButton(sImageBase + "/addnew.gif" , "ComVsStaticValueView1_Insert.jsp", "Insert a New Record");
tb.getContainer().addButton(sImageBase + "/editrec.gif" , "ComVsStaticValueView1_Edit.jsp", "Edit Current Record");
tb.render();
%>
<br>
One way of doing this is to put P2 in the session so that it can be accessed by POLGENMA106.jsp but this method is not preferable.
Please Clarify.

Answer 1

John Jdev :Are you using JDeveloper 3.0 or 3.1?
... I assume 3.0.
Archana : Yes.
Jdev : Are you trying to test this within JDeveloper 3.0?
... I assume so, but if not...please let me know.
Archana : No, Iam not testing it within Jdev 3.0. I've deployed it in Java Web server 2.0 and Iam getting these parameters from the request.
Jdev : You should note that JDeveloper 3.0
supports running and debugging ONE JSP, not
chained JSP/Servlets.
Archana : Okay. But I din't test it using Jdev. Actually the NavigatorBar bean appends the implicit parameters "<view name>_NAVIGATE" to the JSP name specified in the setTargetUrl(), without checking if the string supplied to setTargetUrl() has a paramter already, that is the problem. So instead of appending "&<view name>_NAVIGATE", it goes as "?<view name>_NAVIGATE".
Kindly provide a solution for this.
Thank U !
