> Key: COCOON-1552
> URL: http://issues.apache.org/jira/browse/COCOON-1552
> Project: Cocoon
> Type: Bug
> Components: Blocks: Databases
> Versions: 2.1.7
> Environment: Operating System: Windows NT
> Platform: PC
> Reporter: Andrew Stevens
> Assignee: Cocoon Developers Team
> Fix For: 2.2-dev (Current SVN), 2.1.10-dev (current SVN)
>
> I have a pipeline which consists of a file generator, the SQL transformer, and
> an XML serializer. Unfortunately, I forgot to add the database driver to the
> load-classes init param, so the DriverManager was unable to find anything to
> handle my serverURL and hence the SQL transformer was unable to get a
> connection.
> I expected to get an error, however, I didn't expect it to be a
> NullPointerException (stack trace below). Looks like the transformer needs to
> be more careful about what it passes into Xalan? At least in the Xalan 2.6.0
> sources, ensurePrefixIsDeclared method has a check for null namespaces, but
> not
> for a null rawName...?
