Summary: ClassCastException in NamingContext
Initial Comment:
Hi.
I get a ClassCastException in NamingContext when I
deploy the EAR file from Bug#809152 -- maybe this is a
feature feature -- I would like to know why I get the
exception:
22:11:53,243 WARN [NamingContext] Failed to connect
to localhost:1099
javax.naming.CommunicationException: Failed to connect
to server localhost:1099 [Root exception is

I have tried with JBoss-3.2.2 and Branch_3_2; both
have the same problem.
When I do: "telnet localhost 1099" I get:
Trying ::1...

The IP address is my machine address.
If I replace all references from localhost to my
machine name I get the same problems.
nmap shows that the JBoss ports are open.
I must be doing something wrong...
Thanks in advance!

I still thinks it is a regression between the RC4 and the
current Branch_3_2.
It used to be possible to distribute an application (EAR)
which contained the jbossall-client.jar file inside the WAR
such that I could use the WAR file outside a JBoss
environment.
The remote object doesn't have a classloader and codebase
registered with it -- so it may be a classloader issue.
I get a lot of "New jmx UCL with url null" around the
initialization of the bug.ear file -- I don't if this is
the problem (maybe Scott has an idea).
I havn't changed the default settings in JBoss other than
added the two login-config.xml entries.
The result is that my build.xml scripts has changed between
the RC4 build and the Branch_3_2 build -- my code hasn't.
Hope this gives an idea of my thoughts.

As it seems to work, I close the issue.

I tried to remove the
bug.ear/bug.war/WEB-INF/lib/jbossall-client.jar
file from the archive, since it was a JBoss class that
failed.
And success -- the EAR file works perfectly now ! :)

I read the ClassLoading.pdf when I saw that the classloader
for org.jnp.interfaces.Naming and the stub object was
different (getClass().getClassLoader()). A good read btw.
Below is the output from the displayClassInfo operation:

I think that the
ClassLoader: null
Null CodeSource
lines looks strange.
I can generate the ucl.log if needed.

I spend the weekend looking into this issue, but didn't
find a solution; the returned object is a
org.jnp.server.NamingServer_Stub which implements
org.jnp.interfaces.Naming.
This should be correct, but the type cast still fails -- no
idea why.
I tried switching JDK to jdk-1.4.1_05 but that didn't help
either.
Finally I looked through my harddisk and found my old build
[3.2.2RC4 (build: CVSTag=JBoss_3_2_2_RC4
date=200309172341)] -- which I used to create bug#809152.
This build still works on the tested machines (no
ClassCadtException).
So it must be a regression between this build and
JBoss-3.2.2 and current Branch_3_2.
Hope someone has an idea how to solve it.

A small update:
1) The IP address in the telnet should be 127.0.0.1 -- I
got two cases mixed
2) Current output is on Linux with Sun 1.4.2_02
3) Same problem with Win2000SP4 and Sun 1.4.2_02
4) Linux machine is connected to Internet behind firewalls
5) Win2000 is not connected to Internet
Hopes this give you a better idea.
