Running tomcat with JRE + tools.jar
Hello All,
I know you're supposed to run tomcat using the SDK but I want to avoid
that if possible. Instead, I am trying to run tomcat 4.1 using the
JRE...and I still want the ability to compile servlets. I read
somewhere that you can accomplish this by copying tools.jar to the
$jre_home/lib directory. I tried this and I get:
> ./startup.sh
The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
My JAVA_HOME is set to the base of my JRE (/usr/java/j2re1.4.2_01/).
That path is valid. Tomcat starts if I set JAVA_HOME to the base of my SDK.
What do I have to do to get Tomcat to run with the JRE? Is there a doc
for this?

redistribute the JRE. Perhaps Sun's policy has changed?

It is possible. You are on the right track.
You also need to modify the startup scripts a bit. See below:
> > ./startup.sh
> The JAVA_HOME environment variable is not defined correctly
> This environment variable is needed to run this program
If you search on this error message, you will see that it comes from
setclasspath.sh :
% grep "The JAVA_HOME environment variable is not defined correctly" *
setclasspath.sh: echo "The JAVA_HOME environment variable is not defined
correctly"
setclasspath.sh: echo "The JAVA_HOME environment variable is not defined
correctly"
setclasspath.sh contains the following code:
if [ ! -r "$JAVA_HOME"/bin/java -o ! -r "$JAVA_HOME"/bin/jdb -o ! -r
"$JAVA_HO
ME"/bin/javac ]; then
echo "The JAVA_HOME environment variable is not defined correctly"
Neither javac or jdb are included with the JRE. You need to modify this
expression so that it only looks for lib/tools.jar . I don't think the jdb
is mandatory unless you need to run in debug mode.
And then, you need to make sure the CLASSPATH includes the path to tools.jar
. I forget exactly how to do that.

That's because Tomcat can find the jdb & the javac, because they are under
your SDK.

Read the license included with the JDK. It will specifically state which
files can be redistributed.
