Hi All,

I am getting the below error when i am trying to run my app.
I am sun one app server.I have deployed my classes and jsp using the deply tool.


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.

I will bet that currently, you have a JRE_HOME defined in your Tomcat configuration, but not a JAVA_HOME. Define JAVA_HOME in your Tomcat configuration and the problem should go away.
