unable to compile class to JSP!

[josepco]

Hi,
Since my 1st thread, I could find how to have access to my web-app's index.htm.
But, this page point to jsp pages through Spring controler.
My problem is :
----------------

But, I've:
servlet.jar and tools.jar in tomcat/common/lib
ant.jar in $JAVA_HOME/jre/lib/ext
my CLASSPTH is empty
my PATH = /usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/ant/bin:/usr/local/mysql/bin:/usr/local/java/bin:/usr/local/firefox:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin

I'm using tomcat 4, Spring, mysql 5, jdk 5.

I've been stuck with these configuration error since last week, and google bring me the same 'already-tried' information.
Please, help me.

Thanks.

Does the file :

$JAVA_HOME/bin/javac

exist ?
