On a Suse 10.1 I am trying to install Tomcat.

After several trials, now I have a fresh installation of Tomcat5.5, after uninstalling java, jakarta, tomcat, and deleting dirs and conf files.
The installation comes from openSUSE download repositories, java included.
I install all packages via YAST.

Enabling tomcat in YAST fails with error 7

Log files
start.log
(empty)

catalina.out
/usr/share/tomcat55/bin/catalina.sh: line 321: /usr/share/java/bin/java:
No such file or directory

java seems to be in /usr/share/java

Make sure that /usr/share/java/bin/java exists and is executable. If it doesn't exist runto find out where the java executable is located and create a symlink in the required place:

JAVA_HOME is now set to blank (as it was from installation), and I start Tomcat55 from Yast.

start.log
No JAVA_HOME specified in @@@TCCONF@@@/tomcat55.conf and no java found

If I exec
cichis:/usr/share # which java
/usr/bin/java
cichis:/usr/share # ln -s /usr/bin/java /usr/share/java/bin/java
ln: creating symbolic link `/usr/share/java/bin/java' to `/usr/bin/java': No such file or directory

In /usr/bin/ there if already a file java

That means that the path /usr/share/java/bin/ does not exist.
I think that the best thing you can do is to install jdk, or jre using yast, so it creates the paths and sets symlinks and env. variables accordingly.

Installed (in the order, and tried to start T55):
- jre
- jvm (by error)
- jdk

Always the same error, and really /usr/share/java/bin/ does not exist.
Under /usr/share/java I have:
/ant
/axis
/mx4j
/tomcat55
... and files

I've never been too fond of the tomcat packages supplied by Suse or Fedora, they seem to bring more trouble than convenience. Instead I download tomcat from apache.org and unzip the files to wherever I prefer (usually /usr/local). To get it running, I need to make sure that JAVA_HOME exists, which I do like this from the command line:
echo JAVA_HOME=/path/to/jdk-directory >> /etc/profile (if you installed jre instead of jdk, you'd need jre-directory)
echo export JAVA_HOME >> /etc/profile

Then I can simply cd into tomcat/bin and start Tomcat by doing:
sh startup.sh

To shut it down:
sh shutdown.sh

Where are your java tools? like java, javac, javah....
