exception processing/trapping

I am wondering if there is any way with the API to trap certain errors. Right now it seems I can run regexp on the log snippets, but there is no strongly typed error/exception information available via the API.

For example, I start a job using the Java API and the username/password for a Table input step is incorrect. Is there some way for me to get a reference to the SqlException object that is thrown or some Kettle error code?

Thanks.
