Using P13N Caching Service in Cluster (J2EE Apps)-Not portals

Question

Problem Statement: We are using the BEA Weblogic 8.1 app server for developing J2EE application in clustred environiment. We are running four managed servers and one admin server. (two managed servers for each hardware Dell 2250). For application performance we are caching some the data (Database Lookup tables and some dynamic data in appication scope). The problem exists with the dynamic data. When we clear the cache for dynamic data it is refreshing only in one instance of managed server. To resolve this problem, implemented the servlet 2.3 feature(HttpAttributeListner). I came to know that very quickly it won't solve the problem. I found interesting paper on BEA edocs. Here is the solution in BEA Portal world.

Since we are not using the portal, is there any workaround to the solution?
Thanks,

Hi,
One thing that can be helpful is to add the references of the JAR files that you are adding as Used DC in the EAR.
This can be done by adding Library type References in the application-j2ee-engine.xml Deployment descriptor in the EAR project.
