How do you change the port Tomcat listens to

Hi,

I thought this subject might at least get some response. Has anyone ever had
or know anything about the following error I have started getting from
Tomcat? It cause Tomcat to crash and I then need to restart Tomcat.

Re: How do you change the port Tomcat listens to

Posted by Adam Fowler <ao...@aber.ac.uk>.
Hello,

Sounds like you've got a version of Log4J that Tomcat doesn't like. 
You've probably upgraded one of them without upgrading the other. It 
sounds like a Java error where the version of Log that Log4J implements 
is not the one Tomcat is using.

I'd reccommend making sure you have two versions that work together. The 
two latest stable ones should work. (Disclaimer: I haven't tried it, so 
don't sure me if it doesn't!)

Hope that helps,

Adam.
