JPetstore in cluster

[Javier Urbaneja Fan]

Are there any necessary configuration (or modification) steps to install the JPetsore 5 application in a session replication cluster (Tomcat)? I'm talking about configuring caches, make POJOs serializable, etc. This wonderful design, based in beanaction.jar (I wasn't able to find the sources in any branches of Struts repositories), can be considered SOA? I think it make easy to publish some funcionality as web services. Thank you very much.
