JSP displaying a Javabean

[Gerald Spica]

I created a javabean that takes the input from a checkbox for 6 different cabs, Cab 1, Cab2, Cab3 etc. I have private variables cab1Counter++ etc., in my bean with associated get and set methods for each cabCounter. I created the below JSP to give me a summary of my inputs.

MY PROBLEM: If I select an item it gets incremented, but on a second pass if the item is not selected it's counter goes back to 0. I cannot come up with a good way to iterate over my string of cab's entered. Anyone have any ideas?

 
<%@ page import="beans.*" %>
<%@ page import="java.util.Enumeration" %>
<%@ page import="java.util.Hashtable" %>
 

<h3>Summary of your Charge Records</h3>
 
<%
  Hashtable h = (Hashtable) session.getAttribute("charges");
  if (h != null) {
%>
    <ul>
 
<%
      Enumeration charges = h.keys();
      while (charges.hasMoreElements()) {
      String msg = (String) charges.nextElement();
      Dispatcher ch = (Dispatcher) h.get(msg);
%>
 

<%
 
  String[] faveMusic = ch.getFaveMusic();
  
  for (int i=0; i<faveMusic.length; i++)
  if (faveMusic[i].equals("Cab 1")) 
  {
    
    out.println("<ul>");
    ch.setCab1Counter();
    out.println("<li>"+faveMusic[i]);
    out.println("</ul>");
  } 
  
  else if (faveMusic[i].equals("Cab 2"))
  
    {
      
      out.println("<ul>");
      ch.setCab2Counter();
      out.println("<li>"+faveMusic[i]);
      out.println("</ul>");
    } 
  
  else if (faveMusic[i].equals("Cab 3"))
    
      {
        
        out.println("<ul>");
        ch.setCab3Counter();
        out.println("<li>"+faveMusic[i]);
        out.println("</ul>");
      } 
      
    else if (faveMusic[i].equals("Cab 4"))
      
        {
          
          out.println("<ul>");
          ch.setCab4Counter();
          out.println("<li>"+faveMusic[i]);
          out.println("</ul>");
      } 
      
     else if (faveMusic[i].equals("Cab 5"))
       
         {
           
           out.println("<ul>");
           ch.setCab5Counter();
           out.println("<li>"+faveMusic[i]);
           out.println("</ul>");
         } 
     else if (faveMusic[i].equals("Cab 6"))
       
         {
           out.println("<ul>");
           ch.setCab6Counter();
           out.println("<li>"+faveMusic[i]);
           out.println("</ul>");
         }  
      
  else out.println("Nothing was selected");

Hi Gerald,

As state is held in your bean, your bean needs to be persistent between requests. Are you asking how to implement this?

[Gerald Spica]

Yes, I have gotten lost in the realm of state, I want this bean to persist between requests, without EJB.

[Bear Bibeault]

Attach it to the session as an attribute. Be sure not to recreate it on each page.

[Gerald Spica]

It being the bean? I am not sure what you mean. I have a count variable, also private with a get method that increments the count variable ++, and also returns the incremented variable. This works fine. So I am not sure that the state is correct.
