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

[Greg H. <gre...@gm...>]

Sorry, been quite busy lately.

If I remember correctly, MX4J at some point stopped including their  
proprietary adaptor in their release. I think they only ship with the  
standard JSR160 compatible connector. I don't know what version that  
was, you'd have to ask on the MX4J project list or check its  
archives, but I know people have worked this out.
