GlassFish 3 Tip of the Day: Using JDK 7 with JSP Code

A question came up on the NetBeans J2EE Mailing List about using JDK 7 with GlassFish 3.1.2. Specifically, they were getting the error:
org.apache.jasper.JasperException: PWC6033: Error in Javac compilation for JSP
PWC6197: An error occurred at line: 4 in the jsp file: /index.jspPWC6199: Generated servlet error:strings in switch are not supported in -source 1.5  (use -source 7 or higher to enable strings in switch)

The fix is quite simple. You must include a glassfish-web.xml file in your project, and set a couple of properties. compilerSourceVM and compilerTargetVM.

Please see the example below for a complete configuration.
The project will now compile and use JDK7.

That's a really neat fix John. This is one of the most common errors I have come across while trying to use JDK7 with JSP code. Thanks a lot.
