Tomcat Startup

Posted on 2004-08-17

We have itools installed and we run Apache and Tomcat. Recently we upgraded all servers, and after upgrade the Tomcat wouldn't start.
After the install we get a file with no name in the root directory, the file's content is very similar to web.xml file's content, but I cannot be sure since the file has no name. When trying to start the tomcat, it complains that JAVA_HOME is not set,
I tried
setenv JAVA_HOME /usr
Server still doesn't start, but I also realized that JAVA_HOME gets unset once the terminal is shut down.

We tried contacting customer support, all they told us is to wait few minutes for tomcat to start - which, of course is no help.

I did everything following the instructions, still JAVA_HOME is not remaining set.
I'm working on Mac OS10
if I try to
export JAVA_HOME
it gives me 'export command not found' error.

setenv JAVA_HOME /usr/JAVADIRECTORY   >>Are you pointing the java directory ??
at above it seem like you are pointing to /usr directory not java. the java directory might be under /usr but you still need to show which directory it is
and to keep the settings you OS needs to load the JAVA_HOME each time the OS reboots so you will need to add
the code to startup file. in linux bash.rc ??

it doesnt like export since you are not using bash shell or any other that supports export command.
hope thimight help

You need to set JAVA_HOME in one of the Tomcat startup scripts.

Typically you start up Tomcat from a script (startup.sh).
It calls otjher scripts.
One of them sets the value of JAVA_HOME.
These scripts are in the 'bin' subdirectory of Tomcat.
Search these scripts to find where JAVA_HOME is defined, and set it properly for your system.

Then restart Tomcat
(it might be a good idea to reboot the whole machine first, just to have a clean environment).

What is happening is that Tomcat starts in a new process, that does not have the JAVA_HOME variable set, even if you set it by hand before starting Tomcat.

--------------------------------------------
just copy and paste the code in to a .sh file and it will take care of the rest
(Code From Cpanel changed for csh

I actually already fixed the problem,
I needed to add code to the script files, like CajunBill and magicMush sugested, I wish you guys replied earlier, you would save me days of struggle.

I did have to set JAVA_HOME to /usr, the problem wasnt' the path, it was that JAVA_HOME would just disappear once the terminal is shut down, so I didn't know what to do to make it reamin.
