JDK not found....?

[wittgenstein]

Hello,

i'm trying to deploy JBoss Portal RC1 from the sources.
versions:
MySQL 4.1
jboss AS 4.0.1sp1
jdk1.5.0_03

the error message i get when running build.bat is:
"BUILD FAILED

file:C:/Programme/jboss-portal-2.0-RC-src/common/../tools/etc/buildfragments/targets.ent:95: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK"

my JAVA_HOME does point to the correct directory...i even checked for spelling...

any ideas? THX in advance...

can you print your JAVA_HOME value...

also if that is set correctly, you might want to add the rt.jar to your CLASSPATH env variable. I'd also double check the reference to the JAVA_HOME inside of the ant build file to make sure it's pointing to what you think it should be pointing to...
