[jboss-user] [Beginners Corner] - problem caused by distributable tag

[ddai]

Hi folks,

My session replication just doesn't work. Once I add distributable tag into the web.xml, an exception was thrown. After I delete it, things look fine. So I guess maybe  is the trouble maker. Then what is the problem and what should I do to fix it?

Here is the outline of that error. Please help me. It is very important to me. Thanks a lot!!
