Re: [cobalt-developers] How to Install Tomcat 4x on a Linux machine

[Mike Wes <m_wes@xxxxxxxxx>]

Hello,

Thank you all for the replies. Is it possible to make a
more step-by step manual?

For example in my case, when I tried to download Tomcat, I
found a couple of bibaries, rpm´s etc . Which one is the
good one? When I tried to install a rpm (I hope it is the
good one), the location was different then the below
refered "/opt".

And what is a symlic? A symbolic link?

The problem (of us all) in my case that the server is used
for hosting a couple of websites, what this type of server
is doing perfect! Fot that reason nobody likes up to screw
his server so everybody/some has to reïnstall their Raq
server again.

Is it possible to introduce a real step by step manual,
including the JDK and Tomcat download-links (for Tomcat I
found a jungle of packages)?

Other thing: What is Tomcat doing, what does JDK and what
is the relation between Tomcat/Apache (and what is the
worst-case scenario).

I had a programming course and want to extend it in
free-time, but my background is at this moment nhil.

Regards,

Mike Wes
