My cluster has 2 servers A, B. when I deploy an WebCenter Custom Portal application to weblogic cluster, application on server A work well and application on server B is failed. Log on failed server is “what do i do: seems an odd quirk of the EJB spec. The exception is:java.lang.NoClassDefFoundError: Oracle/jdeveloper/db/adapter/DatabaseProvider”
When I reconfig cluster and then deploy, application on server B work well but application on server A is failed.
Please advise what should I do in this situation?
It seems your Application is running with non-seralizable objects where non-searlizable are not supported on cluster environment.
Please check server logs whether you have such warning messages are not.
Let me know if you need any further help on this issue.
