JPetstore in cluster
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.

Hardware is higher performance and is usually easier too. If your
requirements and budget are minimal to start, then you can try the Apache
software method to begin with.
Cheers,

This approach you just gave me will be much more convenient. Sorry about being a little Off-Topic. Do you think a hardware load-balancer will be much better than Apache load balancing with affinity? Would you configure it to balance by CPU load?
Clinton, thank you very much for your reply. This is the magic of open source, real support, from the very inventor himself.

A better alternative is to not cluster.
Buy a hardware load balancer, enable server affinity and deploy as many copies of JPetStore to as many computers as you like...without all of the hassle above.
Cheers, ;-)

Yes, and yes. You'll need to make POJOs serializable.
You'll need to eliminate the use of PaginatedList and possibly turn off lazy
loading as well. Then you need to use a distributed cache such as OSCache.
A better alternative is to not cluster.
Buy a hardware load balancer, enable server affinity and deploy as many
copies of JPetStore to as many computers as you like...without all of the
hassle above.
Cheers, ;-)
