[news.eclipse.technology.jsr220-orm] Re: Can't create connection

["Robert Greene" <rgreene@xxxxxxxxxxx>]

Hi Guys,

There is a note on this known issue on the download pages notes on Hibernate
support.   The Database explorer must be open when creating the connection
otherwise you get this error.  So, if you are in the Java Perspective, you
need to explicitly open the Database explorer ...  Window>>Show
View>>Other>>Data>>Database Explorer.   If you are in the Persistence
perspective, then we automatically open this view so you would not get the
problem.

Hope this helps.....
-Robert
