Hi,

if I try to connect to a local (running) db instance of OrientDB 2.1 via DBVisualizer 9.2.8 I get the following exception/error messages:

An error occurred while establishing the connection:

Notes:

* I use the latest official JDBC driver from the OrientDB website "orientdb-jdbc-2.1.0-all.jar" and have configured the driver in DBVisualizer using Tool "Driver Manager" where I used the Database URL jdbc:orient:remote:localhost/<database_name>

* I can connect to the database using OrientDB Studio on localhost:2480, though


Thanks a lot for your help, much appreciated!

Best regards, Christian

The error shows you're using CORBA? Could you please post here all the JDBC params you're using?

Hi again - I do not use CORBA (at least not on purpose!). However, I just added the JDBC driver's file path (the directory where the JAR file is located) to DBVisualizers Driver Search Path, restarted DBVisualizer and... it works! So, looks like this is a bug with DBVisualizer rather than a configuration problem.

Thanks anyway!

Best, Christian
