I m using Jdev 126.96.36.199.0 . I did Help -> check for Updates -> checked Open source and Partners Extension ->next->Checked Jheadstart evaluation version 188.8.131.52.15 -> next -> downloaded->restarted Jdev.
After doing this when I am right clicking on View Controller application , I am unable to see option of "Enable JHeadstart on this project" . Neither i am seeing Jheadstart runtime library in project preferences-> libraries.
Ah, OK, yes that was the wrong JHeadstart version.
I checked internally and there was indeed something wrong with the config files for the update center.
It has been fixed now, JHeadstart 184.108.40.206.28 now shows up correctly using the JDeveloper Check for Updates function.
