  • I'm using Mango 1.9.0, Eclipse Helios, and j2ee 5.


  • With a fresh install of Helios it works for me. (Was still using Galileo.) I have J2SE6 though. Have you tried a different Java version?


  • Could you point me to where I can download J2SE6. The only thing I can find is packaged under glassfish, and it doesn't seem right that I should be using an api that is glassfish specific.
