[Mc4j-development] Error while connecting using MC4J with Tomcat 4.1.24

[Alex R. M. <ale...@ap...>]

Hello, 
    I am having problem making MC4J 1.2 beta 9, work with tomcat 4.1.24 (yes
its old, but we are in process of upgrading). Here are the issues:

1. In the documentation that I was able to gather, its mentioned to modify
the jk2.properties with the following line of code:
mx.port=9000
But when I make this change and restart tomcat, even my normal http request
are picked up by the mx4j adaptor, as seen in the log below. What could I be
doing wrong for this to happen?

Exception during http request
mx4j.adaptor.http.HttpException: HTTP/1.1
        at 
mx4j.adaptor.http.HttpInputStream.parseMethod(HttpInputStream.java:633)
        at 
mx4j.adaptor.http.HttpInputStream.readRequest(HttpInputStream.java:277)
        at 
mx4j.adaptor.http.HttpAdaptor$HttpClient.run(HttpAdaptor.java:965)

2. In the forums, I read that just the line mx.port=9000 is not all that
needs to be added, but
mx.enabled=true
mx.jrmpPort=90007
mx.jrmpHost=localhost

Also needs to be added. Is this all, or something else is needed too.

3. While I try to connect to the tomcat server from the MC4J application, I
get the following error:

java.io.IOException: Failed to retrieve RMIServer stub:
