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.
