Hi Claudia,
according to the error message there is a NullPointerException in your
JSP code.
Take a look at the java file which is generated from the jsp by jboss
(should be found somewhere in your jboss server, search for
"testz_jsp.java"). At line 59 of this file you should find the erranous
line. Please post this file here.
Best regards

Hi,
I tried same thing and it seems like TigerHome (generated by XDoclet
when TigerBean is created) can't find "Tiger" bean, it actually throws a
Naming Exception. You can confirm that if you replace JSP code by some
thing like this
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<%
com.zoo.Tiger tiger = null;
try{
com.zoo.TigerHome home = com.zoo.TigerUtil.getHome();
tiger = home.create();
}catch(Exception e)
{
//it is never good to ignore exceptions
e.printStackTrace();
}
%>
<b><%= tiger.roar() %></b>
</body>
</html>

I might be mistaken, but I think only JBoss 3.2.3 is supported by WTP...

After many days thought I have found the problem. I think...
AS i said, i am following the WTP Tutorial - Building a Simple EJB
Application.
I had an error when i run the JSP page in the server. Using the code shown
in tutorial:
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<%
com.zoo.Tiger tiger = null;
try{
com.zoo.TigerHome home = com.zoo.TigerUtil.getHome();
tiger = home.create();
}catch(Exception exception)
{
}
%>
<b><%= tiger.roar() %></b>
</body>
I get an Exception:
16:36:56,046 ERROR [[jsp]] Servlet.service() for servlet jsp threw
exception
java.lang.NullPointerException
So i went step by step. My JSP page:
<html>
<head>
<title>Insert title here</title>
</head>
<body>
<%
com.zoo.Tiger tiger = null;
System.out.println("Step1");
%>
<%
com.zoo.TigerHome home = com.zoo.TigerUtil.getHome();
System.out.println("Step2");
%>
</body>
I find that Step1 is done perfectly but Step 2 NO!! Because in
TigerUtil.getHome() there is the problem in the line:
javax.rmi.PortableRemoteObject.narrow(objRef, narrowTo);
The exception generated is:
java.lang.ClassCastException
After search in all forums and the all www :) I find:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4730878
"javax.rmi.PortableRemoteObject.narrow(...) casts the returned result to
the java.rmi.Remote interface...This behavior is contradiciting the spec
of javax.rmi.PortableRemoteObject.narrow(...): "Checks to ensure that an
object of a remote or abstract interface type can be cast to a desired
type"
Since the abstract interfaces do not implement Remote, this code will
break for customers using abstract interfaces in their application. This
code results in ClassCastException..." from Sun
What you find? I am correct?
If yes, as to exceed the problem?
Please, send me feedback
Thnkxx

Hi Claudia,
what's your Java version ? I used this Util class with 1.4.2_09 and it
worked fine. Is there a chance the the JNDI names for local/remote
interfaces got mixed up ?
Post your complete ear project to make it easier to find the problem
(use "export to EAR file" with option "export source files").
Best regards

You mean how to attach the file to the newsgroup post ? This depends on
your newsreader.
