Summary: sessioncontext not set when calling
Initial Comment:
I have written a simple session bean which echos a
string. I access this bean via the web.
I can secure this bean using when i access it from a
servlet.
When I access it from a JSP the session context is not
set. I tried this with the JBOSS catalina bundle:
JBoss-2.4.4_Tomcat-4.0.1
JSP file
--------
<html>
<head>
<title>
echo
</title>
</head>
<jsp:useBean id="bean1" scope="session"
class="echo.EchoBean" />
<jsp:setProperty name="bean1" property="echo" value
= "Hello Erik" />
<body>
<h1>
JBuilder Generated JSP
</h1>
</body>
<%= bean1.getEcho() %>
</html>
Bean
----
package echo;
import java.rmi.*;
import javax.ejb.*;

The cookies flag belongs in the tomcat4-service.xml
descriptor, not your web.xml descriptor. See the latest
2.4.5RC3 release.

I added the following to web.xml:
<context-param>
<param-name>cookies</param-name>
<param-value>true</param-value>
</context-param>
Still the sessioncontext of the EJB is null when called from
the JSP. When calling from a Servlet it works.
I get the following exception
java.lang.NullPointerException

Set the DefaultContext cookies attribute to true to enable
sessions based on cookies. This is now the default.
