Re: [Springframework-developer] JasperReports Support

[Patrick B. <pbu...@gm...>]

Juergen,

Well, it turns out, that is what I decided to do. My reporting service
will throw a "ReportingException" that will basically wrap the
JapserReports exception as a runtime exception.

Thanks for the insight into why it was designed that way in Spring. It
does make sense to do it that way.
