java.lang.RuntimeException+ Axis

when I execute webservice using Axis an error appears:

"java.lang.RuntimeException: No compiler found in your
classpath! (you may need to add 'tools.jar')"

I got the problem that java.home property in the Happy Axis page is pointing to the JRE, so tools.jar is missing in that directory which is actually present in JDK

How do I change this property of Axis to point to JDK directory?

I tried creating a new JAVA_HOME variable and restarted tomcat, but in vain.

Please help me

copy the file tools.jar from your jsdk\lib\ into the folder common\lib\
from your tomcat server.
