On our production server (Suse Linux) we run a Tomcat server. From
time to time, our users tell us, that our web application is running

Starting the command "top" I see that one Tomcat-Process is running

I would be really thankful if somebody could decipher the below
statements for me. I have started to work on web services using Axis

I already installed the newest versions of java, which in my case

is there anyone who can help with this problem.  I have a piece of
java software that is sitting on my webserver.  I can run the jar

I am thinking about learning to programme in Java. I have heard lots
of good stuff about it, but really all I get to read is what people
