Do you have JDK installed too? Make sure you let tomcat know where your java compiler is located.

This problem occurs when at the time of installation of Tomcat you make it point to JRE instead of JDK. Reinstall Tomcat and when it asks for Java path, provide it the path to your JDK instead of the default JRE which appears there.

Hi, You first make sure that all the paths are set correctly. most important all the jar files for Jsp and servlet should be at right place that will make you JSP compiler to work.
