Can't usebean in JSP in Java 2 sdk ee1.3 server

Question

I have created a jsp page which used a bean but everytime I accessed the bean from the J2ee server ..it will always displayed the error that the bean class is not found..
I have try to deploy the jsp as a web component using the deploytool but got the same error ...
I am using jdk1.3 and java 2 sdk ee 1.3 in windows 98se
Where do I have to put the class file?
Is there something wrong with my classpath
Do I need the change some of the properties file? if not what other solution is there....
I am completely lost...I have double check the jsp code and the bean code..they are fine...Just couldn't figure out the solution..
Pls help me come up with a solution

Answer 1

Maybe it would be easier if I include the error message that I got and also the files.
I use J2EE server 1.3 so there is only a public_html folder, I can't find any webapp folder...public_html folder contain the context of the application...where do I put the class file there or the package
Here is the error that I got while executing the jsp page
org.apache.jasper.JasperException: Unable to compile class for JSPc:\j2sdkee1.3\repository\default\web\_0002fusebean_jsp.java:61: Class org.apache.jsp.BankAccount not found.

here is the bean code:
import java.io.*;
import java.sql.*;
public class BankAccount
     private String sAccountID=" ";
     private String sPin=" ";
     Connection connect=null;
     Statement state=null;
     ResultSet result=null;
     public void setSAccountID(String sAccountID)
          this.sAccountID=sAccountID;
     public String getSAccountID()
          return sAccountID;
     public void setSPin(String sPin)
          this.sPin=sPin;
     public String getSPin()
          return sPin;
     public BankAccount() throws ClassNotFoundException
          Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
     public boolean AccountValidate()
          boolean validate=false;
          String sPinno="";
          try
               sAccountID=getSAccountID();
               sPin=getSPin();
               connect=DriverManager.getConnection("jdbc:odbc:Bank","","");
               String strquery="select cPin_no from Login where cAccount_id='"+sAccountID+"'";
               state=connect.createStatement();
               result=state.executeQuery(strquery);
               while (result.next())
                    sPinno=result.getString(1);
               sPinno=sPinno.trim();
               sPin=sPin.trim();
               if (sPinno.equals(sPin))
                    validate=true;
          catch(Exception e){}
          return validate;
here is the jsp :
<%@ page language="java" %>
<jsp:useBean id="BA" scope="application" class="BankAccount" >
<jsp:setProperty name="BA" property="sAccountID" param="accid"/>
<jsp:setProperty name="BA" property="sPin" param="pin"/>
</jsp:useBean>
<html>
<head><title>result page</title></head>
<body>
<%
     String accid=request.getParameter("i1");
     String pin=request.getParameter("i2");
     out.println("welcome "+accid);
     boolean validate=BA.AccountValidate();
     if (validate==true)
          out.println("the user is validated");
     else
          out.println("the user is not valid");
%>
</body>
</html>
here is the simple html file
<html>
<head><title>user validation</title></head>
<body>
<form method="post" action="usebean.jsp">
<table border="0" cellspacing="1" cellpadding="5">
<tr>
     <td width="100"> </td>
     <td align="right"><h1><font color="red">Welcome to Bank</font></h1></td>

     <td width="100"><b><font color="blue">Account ID:</font></b></td>
     <td align="left"><input type="text" name="sAccountID" size="30"></td>

     <td width=100 align=right><b><font color=blue>Pin Number:</font></b></td>
     <td align=left><input type="password" name="sPin" size="30"></td>
</tr>
<tr>
     <td width=100> </td>
     <td align=left><input type=submit value=submit></td>

</table>
</form>
</body>
</html>
what changes do you suggest?
I try testing and creating a simple package just to ensure I can create package and it is accessible but I can't access the package
Here is what I did...
I created a file displayclass.java which contains the package declaration as follows
package mypackage;
public class displayclass
     public String displaytext()
          return "displaying text";
I compile it using javac -d . displayclass.java
I check and the package named mypackage is created under the current directory which is c:\java\jsp
then I created the usepackage.java which use the mypackage package
here it is
import jsp.*;
public class usepackage
     public static void main(String args[])
          displayclass dc=new displayclass();
          String string=dc.displaytext();
          System.out.println(string);
Then I set the classpath as "set classpath=%classpath%;c:\java\jsp\mypackage" without the quotation marks ofcourse
I found to my dismay that when I compile usepackage.java.. the compiler generated the following error message
usepackage.java:7 cannot displayclass
bad class file: c:\java\jsp\mypackage\displayclass.class
class file contain wrong class: jsp.displayclass
Please remove and make sure it appears in the correctsubdirectory of the classpath
My brains are already over the limit...the level of frustration at not be being able to make a simple package thing work after facing hurdles after hurdles in JSP...
What solutions do you suggest for the above 2 problems --the one with the jsp and the one with the package..
I use jdk1.3 and j2sdkee1.3, windows 98se
they are all working fine
I really can't comprehend that the people at sun if they admit that j2sdkee1.3 can work in windows 98 with minor tweakings and instead of leading us to a forum with suggested solutions..why can't they simply support the damn thing in windows98 if it can work on windows98...so much for platform independence..or do they prefer us to upgrade to windows NT or windows 2000 :-)
I feel that it would be way too simple for them to make the batch file to work properly...I am indeed surprised as it wouldn't take much of a time for them. Don't you all think so?
As regards the stuff not working without package...it just is too much...I am close to boiling point...why can't they spare a thought for that? I have seen many of my classmates simply throwing up their hands in desperation :-) it is making life a living hell for us---as we are not genius..it depends upon the genius, if at all they are, to make something more userfriendly
anyway pls help me!....I have to finish my assignments on my home computer...
