Hi Mark,

Thanks a lot for your response.
I will certaily start using the parallel deployment immediately, that seems
to be easy and will solve the issue about deploying new WARs frequently.
Then I will implement a load balancer, in order to have two separate Tomcat
instances, that will solve more critical situations.
