In case this helps anyone else desperately searching the archives one day
hence:
The jsp *works* under Tomcat (NT), Caucho Resin 1.1.5 (NT), WebLogic (NT),
and Orion 1.3.8/JDK 1.3 on linux.
The exception occurs under Orion 1.3.8 *and* Orion 1.4.0 on NT under jdk
1.2.2 *and* jdk 1.3.
Once again, I'd appreciate if anyone had any clues; I suspect possibly a
bug, possibly a classpath conflict; I had to put a lot of weblogic classes
in the classpath, and the weblogicaux.jar has a lot of com.sun.* classes in
it, such as com.sun.java.util.collections.*, etc.

Hi there.
We're using WebLogic on our core platform for now, alas, but I'm hoping to
go with Orion in our web farm, using it as a JSP/Servlet environment
initially, and then expanding its duties to erode on WebLogic.
I've run into a little snag in my initial test. I've got some test EJBs
deployed on weblogic, and I'm trying to use them in a simple JSP I deployed
in the orion default-web-app directory. I'm using the following JSP snippet:
<%@ page contentType="text/html"
import="java.io.*,java.lang.Integer,javax.naming.*,javax.ejb.*,weblogic.comm
on.*,test.*,java.util.Hashtable" %>
<%
PingHome home = null;
Hashtable env = new Hashtable(5);
env.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL, "t3://cjacobs:7001");
Context ctx = new InitialContext(env);
try {
home = (PingHome) ctx.lookup("PingHome");
} catch(Exception e) {
// ...
}
%>
The line "home = (PingHome) ctx.lookup("PingHome");" generates the following
exception, (full stack trace below).
javax.naming.CommunicationException [Root exception is
weblogic.rjvm.PeerGoneException:
- with nested exception:
[java.lang.NoClassDefFoundError: weblogic/service/BasicServiceStub]]
I'm kind of mystified - the class weblogic.service.BasicServiceStub *is* in
the classpath (Class.forName() doesn't generate an error).
weblogic/service/... looks like a path, not a class. WebLogic itself has
complained "Exception on send : weblogic.rmi.ConnectException: Attempt to
sendMsg using a closed connection" several times during these tests.
I only get the exception if the lookup succeeds, i.e.
ctx.lookup("SpoddySpodSpod") throws a javax.naming.NameNotFoundException as
expected.
I tried this code in Tomcat, and it worked perfectly. Any ideas?
Thanks,
Colin
