[wildfly-dev] Internal Server error

Hello and Merry Christmas I have a maven web application, which contains only REST services. This is a very basic application. The whole app created with Netbeans auto generate tools. I have a Debian Wheezy server and when I deploy my war everything is good, but some hours later REST service is not respond, and I only got Internal Server Error. I had to disable my application , after I have to disable Datasource, re enable datasource, and after that re deploy my program. Log: 33m08:57:20,799 WARN [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-3) SQL Error: 0, SQLState: 08S01 08:57:20,800 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-3) The last packet successfully received from the server was 58,901,043 milliseconds ago. The last packet sent successfully to the server was 58,901,043 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. 08:57:20,805 ERROR [org.jboss.as.ejb3.invocation] (default task-3) JBAS014134: EJB Invocation failed on component PartnerFacadeREST for method public java.util.List com.joco.nyomtserv2.service.PartnerFacadeREST.findAll(): javax.ejb.EJBException: javax.persistence.PersistenceException: org.hibernate.exception.JDBCConnectionException: could not extract ResultSet How can I set the timeout or the autoReconnect? Thank you. Joe
