Please check this file: jasper-jdt.jar. If it doesn't exist in your /lib directory, than you should get one.

Probably means exactly what it says, you don't have a Java compiler. You need to install a SDK so that it can compile JSPs . Check for Java SDK and don't forget to set JAVA_HOME .

See this discussion for troubleshooting your problem.
