If you're using Tomcat, you'll need to install a JTA-compliant Transaction Manager. I wrote some instructions on installing JOTM a while back, but commenters recommended I don't use JOTM.

Fadi, thanks for your super quick response! I am using Tomcat 5.0.28. Just a couple of followup questions: -What exactly is the userTransactionName you are setting in the JtaTransactionManager? -How does the transactionManager know that each save method from each session factory needs to be executed before a commit? (is it becuase of the configuration in txProxyTemplate?) -When I actually implement this, will I be placing 3 dao "saves" within one manager method?
