I am investigating the use of embedded Tomcat in one of my projects. During my testing, I ran into an error message:

No Java compiler available

I was unable to find significant information about this message via Google so I downloaded the Tomcat source and poked around. To make a short story shorter, include the following jar files to fix this issue:

TOMCAT_HOME\common\lib\jasper-compiler.jar
TOMCAT_HOME\common\lib\jasper-compiler-jdt.jar
