Hi Tim (et al.),
ok, I understand the necessity for using different JDKs. I thought that
adjusting the JAVA_HOME environment variable for certain situations
might be the same effort as adjusting the PATH environment variable.
Maybe an option would be to use the JAVA_HOME/JRE_HOME variables if they
are present and to rely on the path if they are absent?
What about tools.jar? Is it needed?
Grettings,

PS: I have to write a setup for an application that uses Tomcat. Tomcat
is running for end users on their local machines and not on an
administrated server. I think the average end user should not be forced
to set an environment variable.

What about multiple JREs or JDKs on your system? Unlike Microsoft products,
you can actually have multiple versions of Java on your system coexisting
peacefully. Try installing the public beta of IE 7--and you are now running
beta software in the core of your OS (assuming of course you have a Windows
desktop ;-)
Also, for security reasons, daemon processes and/or services should not
require or rely on PATH variables.

Subject: JAVA_HOME / JRE_HOME still necessary?
Hi all,
wouldn't it be nice if Tomcat does not need the JAVA_HOME or JRE_HOME
environment variable? After installation of the SUN-JDK these
environment variables are not set. Java is in the "path" and that's it.
While starting Tomcat the script "setclasspath.bat" checks if one of the
environment variables JAVA_HOME or JRE_HOME is set. Then one of these
variables is used to construct the execution commands and to set the
CLASSPATH environment variable such that is contains tools.jar.
As far as the execution command is concerned using one of the
HOME-variables is not necessary as long as Java is in the path.
I wonder why the classpath must contain tools.jar. Tomcat 5.5 uses the
Eclipse Java compiler for compiling JSPs. Therefore I think that
tools.jar is no more needed.
Patching "setclasspath.bat" such that it no more relies on one of the
HOME variables I started Tomcat. It seems to work as usual.
Thanks for your attention,
--Stefan
