Subject RE: MSSQL + Cayenne -> connection problem
Date Thu, 29 May 2008 13:30:57 GMT
I would first try to connect with a graphical JDBC client.
I recommend Squirrel SQL Client. It's released under the GNU Lesser General Public License.
http://www.squirrelsql.org/

Once you get it working with your SQL Server, I am sure it will with your Cayenne client code.

Cheers,

Asunto: Re: MSSQL + Cayenne -> connection problem


Hello Bill,

Thank you for response. I've done what you've said but it didn't help at
all. It's still the same. The delay is huge and usually ends with timeout
exception :(

any other ideas?

Regards,
Mike
