java.lang.NoClassDefFoundError: sun/tools/javac/Main

I am using Tomcat 4.1.30 standalone and am repeatedly facing this issue of

java.lang.NoClassDefFoundError: sun/tools/javac/Main

whenever I try to serve up a jsp from a specific folder within webapps.

I know that this is a classpath issue - but i have checked my
JAVA_HOME and it is pointing correctly to my jdk.
I mean I have lots of other applications working fine in the webapps
folder so JAVA_HOME has never been the issue. (the other jsp files
from other folders in webapps are served just fine)

Also from a google search someone pointed out that TOMCAT_HOME or
CATALINA_HOME needs to be set. I tried setting this too in startup.bat
and catalina.bat (even setclasspath.bat) but in vain.

I know that tomcat 4.1.30 completely ignores the system classpath - so
I have not tried to change that.

Another point is that I compiled using JDK1.5_01 but the tomcat4.1.30
I am using points to jdk1.4.2.

On Tomcat5.5 (pointing to jdk1.5) this worked like a charm - I just
dropped the war in webapps and the jsp was displayed.

Can anybody give me some pointers as to how I can automatically fix
this in 4.1.30?

Thanks in advance,
Anoop

Different versions of JDK should be the problem. I had similar issues
with 1.3 and 1.4. I built Tomcat from source using one jdk and run
Tomcat using another jdk and I got similar errors.
Also post the full stack trace. Perhaps copying tools.jar(of 1.4) to
CATALINA_HOME\common\lib may solve the problem.

Yes - I am sure - This is a line in the setclasspath.bat

set CLASSPATH=%JAVA_HOME%\lib\tools.jar

And my other webapps which have jsp work.
But for some reason this jsp which is in the struts-blank.war gives
this exception.

Are you sure you have the %JAVA_HOME%\lib\tools.jar?...this jar contains the
java compiler that tomcats needs in order to compile jsps pages.

Hope this helps.
