No JAVA_HOME error

After installing T+ (with all pre-requisites) via YAST, downloaded fron SuSE site, I hve defined the MySQL db with the given scripts, and defined in .../trackplus/WEB-INF/Torque.prerties:
- MySQL
- the ip address of the web server instead of localhost.
After rebooting...
The file /srv/www/tomcat5/base/logs/start.log
gives the error:
No JAVA_HOME specified in @@@TCCONF@@@/tomcat5.conf and no java found, exiting...

This looks like Tomcat cannot find a suitable Java installation.

I guess we will have to check the SuSE procedure ourselves; it was not developed and tested by us. In the meantime, I can only guide you blindly. I suppose you do have a JRE or JDK installed. So I either modify the Tomcat startup script in /etc/rc.d (on my SuSE 9.0 server this is called /etc/rc.d/tomcat) and check the script that starts Tomcat (on my SuSE 9.0 server this is located under /opt/jakarta/tomcat/bin/startup.sh). I would then manually set JAVA_HOME in the first script.

Could you try this? Come back then and let me know how far you got, I will try to help you further.

<I suppose you do have a JRE or JDK installed>
In YAST I look for JRE ans after JDK, but nothing is found.

There are:
java-1_5_0-sun
java-1_5_0-sun-devel
listed whith preceeding i (for installed)

And there are a lot of java-1_4... and other java-1_5_0... listed, without their (i) and that cannot be selected for deletion of the package.

I have a /etc/rc.d/tomcat5.

I do not have a /opt/jakarta/tomcat/bin/startup.sh
But /usr/share/tomcat5/bin/startup.sh, with no reference to JAVA_HOME

Before changing anything, I wit for your help.
One question, if this can help.
It seems to me that there is a lot of unused stuff, like java-1_4...
And that I am not able to clean.
Useful to delete something, make some cleanup, and reinstall?
Thank you.

Well, it looks like you do have a Java 1.5 installation. You may have to find out where it is, typically in /usr/java/...

Then you have to look in /usr/share/tomcat5/bin/*.sh for a reference to JAVA_HOME. There may be a file called setclasspath.sh or similar. This might be a good place to look.

There you have to set JAVA_HOME to the place where you found the Java installation (must be Java 1.5 with Tomcat 5.x, x > 0).

You may have to find out where it is, typically in /usr/java/...

Yes. it seems to be in /usr/java (/ant, /javamail, /mx4j, and files are in this dir)

/usr/share/tomcat5/bin/*.sh for a reference to JAVA_HOME. There may be a file called setclasspath.sh

Yes, there is a /usr/share/tomcat5/bin/setclasspath.sh, and also other *.sh files, like catalina.sh, catalina.50.sh, ...
Unfortunately I have not yet enough expertise, and need some help to check.
It sems to me that in this file there are checks if JAVA_HOME is set. On the contrary they echoes messages.
I cannot find a place /file where JAVA_HOME is set to /usr/java (what I would expect) or anything else.
Could you help me to check this? which is the exact command to set this environment variable? and/or where can I find a log?
Thank you.

do not have any news to investigate?
thank you.

I have installed a SuSE 9.2 as a VmWare image (I suppose it is not much different here than 10.0). From Yast I have installed Tomcat. It ends up as you mentioned above under /usr/share/tomcat5. My JAVA_HOME points to "/usr/lib/jvm/java".

When starting Tomcat 5 via "/etc/rc.d/tomcat5 start" two log files are created under /var/log/tomcat5/base. Could you please post these logfiles here?

If indeed no JDK/JRE ist found (I can believe it since I also had quite a bit of trouble with getting the SuSE/Tomcat to work) you could set it like this in catalina.sh at the very top:

The path is the path to the top level directory of the JDK. Underneath you typically find a bin, an include and a lib directory. In the bin directory there should be a "java" executable.

To check if your path is okay you could test it by typing:

I hope this gets you close to a working installation. This is probably not the clean SuSE compatible solution, but I didn't want to wade through all the SuSE specific configuration files.

Here, they are:

hera, they are:

Okay, so maybe you follow my advice. Maybe there is a file tomcat5.conf where you can set JAVA_HOME so that you do not have to patch catalina.sh.

No, I am not able to find this tomcat5.conf or something similar in all the file system!
