[Mc4j-development] mc4j and mx4j in Linux

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Hello all!

I am quite new to JMX and I am trying to install
MC4J using MX4J.

I am having some problems that I do not know hoe to
resolve, that is why I am writing to this list for help.

I have installed MC4JBeta 1.2 Beta 3 and MX4J 1.1.1
over Sun JDK 1.4.2 on Debian Linux.

I have put mx4j libraries into jre/lib/ext and I
have run the console.

When I try to create an MX4J connection I receive
this exeception:

I have look into MX4J 1.1.1 libraries
(mx4j-tools.jar and mx4j-jmx.jar) but I did not
found the class
mx4j.tools.adaptor.rmi.RMIAdaptor_Stub. Instead
there is a class called
mx4j.adaptor.rmi.RMIAdaptor_Stub. So I suppose that
is why it throws that exception.

I have then download mx4j 2.0 Beta 1, but that class
did not appear in any of its libraries. Instead, it
appears in the sources. So I have downloaded and
recompile mx4j 2.0 Beta 2 src and I have generate
the libraries.

I have put the libraries again in the jre/lib/ext
and I have launch the console again. I try to create
the connection again but now I receive this exception:

So do you know which version of MX4J and which one
of MC4J to make it works? Can you pass that versions
to me? Is there any document explaining how to
configure this? Can anybody help me?

I am not register in the list, so please answer with
copy to me.

Thank you very much in advance
