I am having the same issue as Ganesh.
We use synonyms frequently in our group and when I try to look at our synonyms in the Database Explorer, all I can see is the name of the synonyms, not the columns in each of the synonyms. And since I can’t see the columns, I can’t generate hibernate mappings for those synonyms.
We are using:
Eclipse: 3.1.0
MyEclipse: 4.0 M2
Oracle DB: 9i
Could this be a problem specific to Oracle?
