Hi Steve,
I shall attempt to answer this question, but I may leave out something
important.
In my limited experience of linux I have noticed that there are some
subtle differences in the mechanisms used for handling the storage of
environment variables in configuration files from distribution to
distribution.
e.g. Knowing you are using using SuSe, I refered to /etc/profile.local -
it would be different in a vanilla Redhat / FC4.
As rpms are used for many different distributions, it may be argued that
it is too difficult to be comletely compatible with every possible
permutation of configuration - or indeed with every user's specific
requirements - so those configurations are left to the user.
I think java is a special case, because it can be put anywhere you like,
unlike many other applications. Previously you just decompressed it to
a directory and set up the environmet variables accordingly.
Perhaps having a java rpm is unnecessary...
best,
Danny

Thanks Danny,
I've now got Java working correctly and can compile away...
Another conceptual question:
Is it usual 'the Linux way' to have to manually add/edit env vars like
this? Should an RPM do it for you? If so, then should I stop
considering RPMs as being the equivalent of Windows MSI files and more
as a glorified UNZIP/Put-things-in-the-right-folders kind of thing?
A YaST question:
Is installing via YaST EXACTLY the same as doing it yourself from the
RPMs?

Hi Steve,
Once you have done the rpm installation, you can manually check that
java has been installed to /usr/java/j2sdk[version]/
(please ignore your jre for now as it is not needed by tomcat)
Now set up the environment variables like so;
JAVA_HOME=/usr/java/j2sdk[version]
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH
(You can place these in /etc/profile.local on SuSe when you know it
works.)
You can test java and javac at the command line.
If you install tomcat you will also probably need ANT - both Tomcat
and ANT have their own environment variables that need set (see
install docs).
You will also need to set a CLASSPATH environment variable if you put
any java classes in non-standard places.
I hope this helps...
best,
Danny

rpm -Uvh jre-1_5_0_05-linux-i586.rpm
Did this for both the JRE and JDK. Should this set the
$JAVA_<whatever> environment vars or do I need to set them manually?
I'm still confused as to why nothing appeared to happen when I tried
to install with YaST??
