How to delete JDBC drivers in a JAR file
1 Right-click an existing JDBC data source, then choose Edit from the context menu. Edit Data Source appears.
2 Choose Manage Drivers to open the JDBC driver manager.
3 Select the JAR file that contains the driver, then choose Delete.
BIRT Report Designer removes the JAR file and any drivers that it contains from the JDBC drivers directory.
Restoring a JDBC driver
When you install a new version of ­BIRT Report Designer, the process replaces all the files in the eclipse directory and all the drivers installed in the JDBC drivers directory are lost. Reports that use a JDBC driver to access a data source display an error when you run them. Figure 4‑30 shows an example of such an error. To solve this problem, use the JDBC driver manager to restore the drivers.
