I'm running JBoss as a server started from within Eclipse. I have a strange problem where turning on automatic publishing (so the ability to hot deploy a class while debugging, etc.) causes the war to redeploy. When it redeploys it's over 3 times the size of what it was originally. Has anyone seen this? I'd like some method to update Jav...
Hi, As part of all the development of some use cases, I've used a properties file approach to handle almost all the configuration parameters in the project.

Preface: Most of J2EE applications are using container managed datasources through JNDI. This is fine as it gives one place for configuring these connections. The problem arises when we want to use ORM framework (like hibernate) or something that have to know the default schema (mostly for Oracle, may be others too), which can be differe...

My application is deployed as an EAR file. The application has traditionally required that some post installation configuration changes be made. This was easy with the Oracle 10G OAS as the EAR was exploded into a directory thus allowing easy access to configuration files. With 11G, the EAR is not exploded resulting in additional d...
Let's say I'm running a cluster with two Weblogic server nodes on two servers (Solaris, 4 CPUs, 64 GB RAM each). The heap size is maxed out on these nodes and so each server runs with 40+ GB of free memory most of the time and each server usually has on average 30% CPU utilization. Assuming that the application scales horizontally prope...
