Unable to compile class for JSP

Hi
iam using J2EETM 1.4 Application Server for dploying and compiling my JSP with beans. Any boduy can help me solve this probelm.
its given error::::
exception
org.apache.jasper.JasperException: Unable to compile class for JSP
No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK
to the common/lib directory of the Tomcat server, followed by a Tomcat restart.
If using an alternate Java compiler, please check its installation and access path.
