I just installed j2sdk1.4.0 and tomcat4.0.1 on my linux machine. I am new for java .So please tell me how can I checked that Tomcat is running in proper way on my machine and how can I run a java program on my machine.Is there any demo program for it.
I want to say thanks in advance for your innovative help.

Thank you.

Have you configured httpd.conf to hand jsp requests over to tomcat? This is a common mistake. Also by default tomcat runs on port 8080 so just send your browser at that port to make sure you are getting something.

j2sdk1.4 is out already? I wish they'd email me when they release new versions.

I would recommend reading the docs. The sdk is pretty simple if you are installing an RPM on linux. To test it out, just compile a java program and execute it.

You shouldn't need to touch the httpd.conf file for apache unless you're wanting to integrate Tomcat as a JSP container with Apache.

I'm pretty sure that the docs for Tomcat actually covers accessing the default test files to test your installation. Read the RUNNING.txt file.

j2sdk1.4 is out already?
I believe JDK 1.4 is in RC state.
