Hello everyone,

I have installed tomcat but I can't navigate to its manager and I need some help figuring out the parts that I am missing please.

I work on a windows xp machine, but this installation is taking place in a linux server using a SecureCRT session.

The default port for tomcat 8080 is already in use by apache so I had to modify the server.xml  to use port 8081


<Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
               
I did set up the JAVA_HOME and CATALINA_HOME variables.

I was able to do until the $CATALINA_HOME/bin/startup.sh (I believe so..)

and when I try to navigate to URL: http://itzi.jakeros.com:8081/

I get message "Unable to connect" Firefox can't estabish a connection to the server.....

I am not sure what I'm missing, I was not sure if I need to specify the domain such as http://itzi.jakeros.com

on the server.xml file instead that using localhost?

can someone please be able to offer some help?

Thank you,
server.xml.txt

What happens if you try to conenct to it from the same machine and by using

 http://127.0.0.1:8081/

Or what happens if you try to connect by using the machine's IP?

I still get the same error.

I need to indicate that when I run the ./startup.sh

I then open the catalina.out file

and its contents are pasted below.

it seems there is a conflict with the versions but I am not sure if that could be one of the problems, and how to fix it.

would you be able to give me a hand?

thank you.

The cause of this error is a class and virtual machine mismatch. It means that a class that was compiled with Java 1.5 is trying to run on a 1.4 environment. In other words you are using Java version 1.4 to run a 1.5 version class. That is, Tomcat 6.0 needs Java 1.5 and above ot run.

for example, from this page which is the right download?

http://java.sun.com/javase/downloads/index_jdk5.jsp

is it this one: Java Runtime Environment (JRE) 5.0 Update 15

or this one:  JDK 5.0 Update 15
