I'm running into a serious problem with classes that can't be serialized and is a requirement for my app to marshall code across jvm's and over the wire (via a distributed framework).
Any reason why serializable is implemented? Can this possibly be addressed?
Thank you in advance

Hi,
Can we see a stack trace? What objects are you trying to serialize?
Thank you,
Teodor
Hi there and thank you for the reply, and sorry for mine being so late.
I managed to get around the 2 issues I was encountering with serialization and jasper reports;
1.
I had a private static member of the virtualizer being initialized and that would fail. I now initialize it to null and use/dispose in a private method.
2. I ran to a serialization issue with one of the date formatter classes in a jasper report. In my requirement, the report runs in another jvm and does not require any data to be marshalled in return. So releasing all resources before the remote call is complete resolves my issue.
I hope this is clear, and thank you again.
I also see this issue, but only since I started using JRSwapFileVirtualizer and only for large reports.
