org.eclipse.birt.report.data.oda.jdbc.JDBCException: Cannot load JDBC Driver class: org.sqlite.JDBC.
Only later I found a section in the online help where it says that the driver must be copied to a certain plugin directory first (/eclipse/plugins/org.eclipse.birt.report.data.oda.jdbc_2.0.0/drivers).
I've created an enhancement request for the installation instructions.
Update 2008-01-17: Obviously, it's not a bug but the effect of installing Eclipse in
/opt with root ownership, and then starting Eclipse as a normal user.
