I have an issue after migrating spring application from 6.1 o 6.4. My project structure is One Ear file contains 4 war files and the persistence.xml is there at the EAR level along with all jars in the lib. The issue is whenever the server is getting started i am able to send the request and getting the response from only war file but when i try to send the request to other war then i am not getting the response back. So at one time only one war only getting the request and sending the response. Any one please help. i defined all four datasource in standalone.xml correctly the same was working in 6.1 but its not working in 6.4. Please help
