Ooh, that's a toughie. I see you've already done your research and figured out all the problems except this one -- that's good. Unfortunately my only answer to getting jasper to like packageless classes is to hack jasper. This is referenced in the tomcat faq: http://jakarta.apache.org/tomcat/faq/classnotfound.html >So, now that I've spoke my novel, here's my question: Is there a way I >can simply allow Tomcat to import *.class from Simply, no. It'd be a difficult matter if at all possible (I don't know jasper well enough to conclusively say it's possible). >make it work will cost us less time/money than rebuilding all of the >serialized objects in our customers' databases (which I haven't thought >of a good way to do that yet, either). I would seriously start investigating that reconstruction option. What about the following idea: - Add an XML or text saving functionality to your previous (packageless) classes, run them in tomcat 3 to deserialize your current objects and save them as XML or text temporarily. - Now use your new classes on tomcat 5 to read the XML/text and serialize into the database. It might be a lot of work, but it'll also be nice result that's worth your time.
