I'm using hibernate Tools 3.4 with Eclipse (springsource) 3.6 link up with MSSQL2005.

My problem is I can pass the ping test but I cannot get the db schema in "Hibernate Configuration" -> "Database".

When I right click the "Database" and select "Refresh", following error is thrown.

Code:
java.lang.IllegalStateException: zip file closed

Seems like plugins can't load one of the necessary classes because the referenced jar is locked.
Do you have all necessary jar in your project?(other applications don't use them)
