Setting JAVA_HOME ?

[fishy]

i've installed jboss-3.2.2RC4 and when i call http://localhost:8080/jmx-console/index.jsp i get the error:
org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: -1 in the jsp file: null
...
...
...etc

that i've read so much about here. it appears the solution is setting JAVA_HOME to the jdk1.4.x.

would someone inform if this is correct & where to set this variable ?

thanks in advance.

sorted it out. for what it's worth:

in the command line on windows machine -
cd c:\<jboss location>\bin
set JAVA_HOME=c:\<jdk1.4.x> location
run
