I had a report which connects to an Oracle Database through JDBC to get data. Since I reinstalled eclipse and BIRT, my JDBC configuration was lost. Therefore when I tried to preview my report the following error was thrown:
An exception occurred during processing. Please see the following message for details:
Cannot open the connection for the driver: org.eclipse.birt.report.data.oda.jdbc.
org.eclipse.birt.report.data.oda.jdbc.JDBCException: Cannot load JDBC Driver class: oracle.jdbc.OracleDriver
The only way I’ve found to manage your JDBC drivers is to open the new datasource dialog and select “JDBC Datasource”, put whatever name you like and press next. You should see a button with the label “Manage Drivers…”. Then you could add the ojdbc6.jar or whatever JDBC driver you need.
