Hi guys, am new to jsp so hope you can help me out.
Am trying to link up a simple database with a bean, but am not too sure how to do this.

I keep getting the following error:

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 2 in the jsp file: /jsp/email_address.jsp

I've placed email_address.jsp in C:\CARTAPP\jsp and the customer.class file in C:\CARTAPP\jsp\WEB-INF\classes\cust. When i run email_address.jsp on the server i get the above error.

Heres the email_address.jsp file for your convenience:
------------------------------------------------------------------
<%@page import="cust.*"%>

<jsp:useBean id = "newcust" class="cust.Customer" scope ="request"/>
<jsp:setProperty name = "newcust" property = "*"/>

<%newcust.createCustomer();%>

<html>

<head>
<meta http-equiv="Content-Language" content="en-gb">
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<meta name="GENERATOR" content="Microsoft FrontPage 4.0">
<meta name="ProgId" content="FrontPage.Editor.Document">
<title>Email Address</title>
</head>

<body>

<form method = post action = "email_address.jsp">

<table border="0" width="61%">
<tr>
<td width="20%">Email Address</td>
<td width="80%"><input type="text" name="email_address" size="20"></td>
</tr>
<tr>
<td width="20%">Password</td>
<td width="80%"><input type="text" name="password" size="20"></td>
</tr>
<tr>
<td width="20%"></td>
<td width="80%"><input type="reset" value="Reset" name="B2"><input type="submit" value="Submit" name="B1"></td>
</tr>
</table>
<p><br>
</p>

</body>

</html>

--------------------------------------------------------------------

And heres the customer.java file:

import java.sql.*;

public class Customer{
private String email_address;
private String password;

public String getCustomerEmail(){
return email_address;
}

public void setCustomerEmail(String e){

email_address = e;
}


public String getCustomerPass(){
return password;
}

public void setCustomerPass(String p){

password = p;
}

public void createCustomer(){

Connection conn = null;
Statement st = null;
PreparedStatement pst;
//Resultset rs = null;

try{
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
conn=
DriverManager.getConnection("jdbc:mysql://localhost/cartapp");

st = conn.createStatement();
pst=conn.prepareStatement("insert into customer (Customer_ID,Email_Address,Password) "+" values (?,?,?)");
pst.setString(1,"NULL");
pst.setString(2,getCustomerEmail());
pst.setString(3,getCustomerPass());
pst.executeUpdate();
pst.close();
}

catch (Exception ex){
ex.printStackTrace();}

}

}
---------------------------------------------------------------------

Your help is very much appreciated,
Jitesh

I don't see "package cust;" at the top of the Customer.java file. You need to add it and recompile for the Customer.class to be in package cust.

Hey, I just tried doing that, but it still comes out with the same error.
Have I got the files in the right places?
As far as I know, all class files go in the "WEB-INF" folder, and the jsp file has to be outside it.
E.g.
"C:\CARTAPP\jsp" is where email_address.jsp is.
"C:\CARTAPP\jsp\WEB-INF\classes\cust" is where the Customer.class file is.

It all looks fine to me. If you recompiled and replaced the old Customer.class in the cust subdirectory then maybe you need to restart the app server or clear out the work area.

Maybe it's the fact that you're importing cust.* in your JSP and then trying to use a bean called cust.Customer. I've seen instances where doing both together doesn't work well.

tomasz brymora,

This is a pretty old thread and neither of it's participants have posted in a while.
Why don't you start a new one with a description of your problem and the relevent section of the stack trace?

Yes, most people will ignore "zombies" (old threads resurrected).

To make sure that conversations don't occur in two places I'm going to close this thread so tomasz can open a new one in which he can post the details of the problem that he is having.
