Correct Weblogic client libraries for Tomcat 4.1?

Hello everbody,
In my Tomcat 4.1 application who is client of a Weblogic 8.1 sp2,
I�m getting the following error:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:

This is because there are conflicts between the Tomcat core jars and the Weblogic client jars (weblogic.jar or wlclient.jar), so,
the Tomcat cannont correctly serialize to send requests to weblobic.

The question is the folowing:
What is the correct client library for weblogic that I must use
in the Tomcat, which does not cause conclicts?

Someone already gets this error?

Since now thanks for the attention.

I'm having the same problem, and from what I've found thus far is that if your tomcat server is on the same box as the weblogic server, you can use the wlclient.jar and the t3 protocol to communicate.
However, if (as in my case) the weblogic server is remote to the tomcat server it looks that you must use iiop and wlclient.jar to communicate. I've been unable to confirm this, and I haven't successfully communicated in this method either.
I agree. Here's the link:

It's not a secret anymore!
