Outputting xHTML using JSP backend

[reeba]

I want to fetch a set of data from the database and display in the form of a table in the mobile console with frontend as xhtml and backend as servlet.

I tried using the list but got some null pointer exception. I guess its because i cannot use the jsp tags in my xhtml file.

I also wanted an idea as how to go about with xhtml parsing?

Could we see how you tried to get the list?
So your output should just be like a typical xhtml table? eg:
<table>
<tr><th>....</th></tr>
....
etc.

This is my servlet side code:

String sql = "select c_user_id,c_password from t_gb_user_master";
      Statement s = connection.createStatement();
      s.executeQuery (sql);
      rs = s.getResultSet();
      while (rs.next ()){
        //Add records into data list
        dataList.add(rs.getString("c_user_id"));
        dataList.add(rs.getString("c_password"));
      }
      rs.close ();
      s.close ();
      }catch(Exception e){
      System.out.println("Exception is ;"+e);
      }
    System.out.println("dataList SIze : "+dataList.size());
      request.setAttribute("data",dataList);
      //Disptching request
      RequestDispatcher dispatcher = request.getRequestDispatcher(page);
      if (dispatcher != null){
        dispatcher.forward(request, response);

and this is xhtml file:

<form action="Test1Servlet" method="Post">
<table border="1" width="303">
<tr>
<td>username</td>
<td>password</td>
</tr>
<%Iterator itr;%>
<% List data= (List)request.getAttribute("data");
System.out.println("Data Size : "+data.size());
for (itr=data.iterator(); itr.hasNext(); )
{
%>
<tr>
<td><%=itr.next()%></td>
<td ><%=itr.next()%></td>
</tr>
<%}%>
</table>
    </form>
 

the problem is, the jsp tags are getting displayed as it is in the mobile browser... for example (<%=itr.next()%> is displayed as it is in the output table, in the mobile brower)....
Everything is getting displayed properly in the normal browser...

[jkmyoung]

Sounds like the file isn't getting processed as a .jsp file. Have you saved it with a .jsp extension? Further, is jsp supported on the browser you're using?

[reeba]

Yes ... I have saved my file as a .jsp file and my browser also supports it.
I am working on a mobile application.
I jus wanted to fetch the data from the database and put it into an xml file dynamically, and display it in the mobile browser....
and later if i need to fetch the data I should be able to fetch it from the xml file rather than the database....
can u help me as to how i can go about with it

[jkmyoung]

Can you get even simple statements like this to work?

<% 
System.out.println("JSP is working");
java.util.Date date = new java.util.Date();
%>
The time is now <%= date %>

Forgive me for asking: but when you say " I have saved my file as a .jsp file" do you mean:
1. It was always saved as a .jsp file but wasn't working?
2. You just now saved your file to a .jsp file and the .jsp started working but failing?
