Tomcat 3.2.1 and Weblogic 6.0 SP1

[newsgroups.bea.com]

Hi,
We are trying to migrate from WL5.1 to WL6.0 . We are using Tomcat 3.2.1
as our servlet engine. We were using JDK 1.2.2 for our previous release and
now we are trying to deploy the application as is with the same version of
Tomcat and WL6.0.

We are running into problems like weblogic.rmi.extension.stub class not
found.
We were not able to find that class file in any of the jars shipped with
WL6.0

We are still using JDK1.2.2 with Tomcat

Any ideas/suggestions regarding this would be very helpful.

Thanks,
Gopi

Hi,

the only officially supported JDK is 1.3.0. This might be a cause for
your problem (http://www.weblogic.com/platforms/index.htm). As client VM
1.2.2 is supported. If you need to run 1.2.2 on the TomCat side, maybe
you can just run 1.2.2 there and 1.3.0 on the server. If this is not the
problem could you post some more details (start scripts, stack trace,
does the exception occur in WebLogic or in TomCat, what's your OS, etc).

Daniel

Thanks for the response.

That is exactly what we are trying to do and what we are getting is an
exception
that says
weblogic.rmi.extensions.stub not found
We dont see it anywhere in the jar files on wl6.0 server.

We have not tried to compile our classes on the tomcat side with JDK 1.3.0
and we want
to avoid that since tomcat 3.2.1 needs jdk1.2.2

Let me know if you need more information than I have provided here.

Thanks,
Gopi

Gopi,

show me your WL startup script, the Tomcat one and the complete
stacktrace, maybe that gives us a hint on what's going on.

I am working with Gopi on this problem. We are running Tomcat 3.2.1, JDK
1.2.2 on Windows NT 3.51.
We have deployed our EJB's on WLS6.0 sp2. When trying to connect to WL6.0
from Tomcat we get the following exception:

javax.naming.CommunicationException. Root exception is

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

you should remove the old WebLogic 5.1 libs from your TomCat classpath.
Replace them by the new ones shipping
with WL6.0.

Cheers,

Daniel

[Erik Stockton]

Thanks for the response. When I replace the old WL5.1 libs (i.e.
c:\weblogic\classes and c:\weblogic\lib\weblogicaux.jar) with WL6.0 libs
(i.e. c:\bea\wlserver6.0\lib\weblogic.jar) I get the exception listed below.
In WL5.1 the missing class "weblogic.rmi.extensions.Stub" is located in the
c:\weblogic\classes directory. There doesn't seem to be a corresponding
class for this in WL6.0. As always, any help is greatly appreciated.
Thanks, //Erik

Hi Eric,

in Wl6.0 the class seems to have moved
(weblogic/rmi/extensions/server/Stub). Are you sure that there are *no*
old classes in your classpath anymore? A mixture between WL6 and WL5.1
classes might produce such a behaviour where some old classes are
referenced. Can you post your classpath?

Daniel
