JAVA_HOME is not found but tomcat is running. possible?
Hi all ,
I have a tomcat 4.x version (Perhaps it is a old version ,it is in
production and we cant upgrade as of now).
It is running as a window service in Windows2000 server.
in the service icon i can find the path to executable:
C:\Products\Apache Tomcat 4.1\bin\tomcat.exe
My doubt is ,does tomcat.exe needs JAVA_HOME or JRE_HOME defined to run
tomcat in this case as we are not starting tomcat using Startup.bat or
Catalina.bat.
If so,In my system i couldn't find any environmental varible set for
JAVA_HOME or JRE_HOME... i can find only CATALINA_OPTS in it.
It is also not defined in any of the .bat file as well...please help me on
this.thanks
Regards,
Thangavel Sankaranarayanan

Hi Martin,
This is my startup.bat. Here it is doing the job of setting the
CATALINA_HOME if it is not defined and calling CATALINA.bat..
I can find JAVA_HOME ENV variable found in many places in CATALINA.bat. But
i can find any JAVA_HOME variable in the list of environment variables or
in any of the scripts .( which is assigning a value for it)
rem Guess CATALINA_HOME if not defined
if not "%CATALINA_HOME%" == "" goto gotHome
set CATALINA_HOME=.
if exist "%CATALINA_HOME%\bin\catalina.bat" goto okHome
set CATALINA_HOME=..
:gotHome
if exist "%CATALINA_HOME%\bin\catalina.bat" goto okHome
echo The CATALINA_HOME environment variable is not defined correctly
echo This environment variable is needed to run this program
goto end
:okHome
set EXECUTABLE=%CATALINA_HOME%\bin\catalina.bat
rem Check that target executable exists
if exist "%EXECUTABLE%" goto okExec
echo Cannot find %EXECUTABLE%
echo This file is needed to run this program
goto end
:okExec
rem Get remaining unshifted command line arguments and save them in the
set CMD_LINE_ARGS=
:setArgs
if ""%1""=="""" goto doneSetArgs
set CMD_LINE_ARGS=%CMD_LINE_ARGS% %1
shift
goto setArgs
:doneSetArgs
call "%EXECUTABLE%" start %CMD_LINE_ARGS%
:end

As you can clearly see you will need to have either JRE_HOME or JAVA_HOME
environment vars set before executing
Since all of this is conjecture and speculation..do you have the source for
tomcat.exe so we can find out whats going on?

Chuck,
That must be it (Even though the build instructions for Tomcat 6 say 1.5.x or later). Thanks again for the heads up.

Re: JAVA_HOME is not found but tomcat is running. possible?
Posted by Len Popp <le...@gmail.com>.
When it's running as a service, Tomcat gets the location of Java from
the registry, not from JAVA_HOME.
You can change this and other settings using tomcat4w.exe.

Check if you also have a tomcatw.exe in the same directory.
If yes, then it is probably an instance of this :
http://commons.apache.org/daemon
read, then click on the "procrun" link at the bottom of the page.
It sounds a bit obscure, so roughly :
The Java JVM, per se, does not run very nicely as a Windows Service,
because it lacks the interfaces that a Windows Service needs to properly
respond to Windows messages like "shut down service".
So procrun.exe is a program that "wraps" the JVM into a shell that does
have these interfaces.
tomcatw.exe is just the GUI program prunmgr.exe, renamed to tomcatw.exe.
It is the GUI setup tool for procrun.exe, allowing you to tell it where
to get its JVM, what parameters to start it with, etc..
Much like the startup.sh and catalina.sh do under Unix/Linux.
Double-click on tomcatw.exe, then select the Java panel, and you'll see
what I am talking about.
So basically, under Windows, if you want to run Tomcat as a service, you
do as follows :
- configure your JVM environment using tomcatw.exe (prunmgr)
- use tomcat.exe (procrun) as the executable for the Service that
Windows will run
This tomcat.exe will start the JVM, and in the JVM Tomcat (bootstrap.jar)
This tomcat.exe will also catch the signal Windows is sending when it's
time to shut down, and properly stop Tomcat and the JVM.
Now you see why you don't find an environment variable JAVA_HOME ?
tomcat.exe (in reality procrun) does not need it, because it finds the
same information somewhere else (where tomcatw.exe (prunmgr) put it).
(And I am not quite sure where it puts it, probably the Registry).
