I seem to have issues with resolving a data source. I am using NetBeans 7.2 and am in the New Connection Wizard dialog box. I enter the password and the necesaary values for the JDBC URL and than click on 'Test Connection'. I get a 'Connection Succeeded' message. I click on 'next' and land up in the 'Choose Database Schema'. In the 'Select Schema' drop down list option it says 'No Schema' and it's greyed out, meaning I can't get the list to drop down. I than click on the 'finish' button. I than get a 'Unable to add a connection. Connection already exists.' error message.
To verify the 'Connection already exists' part of the message, I click on the 'Services' tab. Under the Databases option I see connection to the said database exists. However back under the 'Projects' tab, I see that I still have a Data source problem. Hope someone can advise me. The RDBMS I am using is MySQL 5.5. Thank you.
