Why do I get an "Unable to compile class for JSP" error?

The following error:

HTTP ERROR: 500
Unable to compile class for JSP
RequestURI=/reEnter.do
Powered by Jetty://

Is displayed when the start-flux-webapp.bat/sh script is calling Java using a JRE, not a SDK. This can be resolved by editing the PATH environment variable and putting the SDK's bin directory before the JRE's bin directory entry.
