we use an web application (FLO) which runs on an web server (windows 2003). A mysql database is connected to that application. The database runs on a database server.The application should move to a new server (windows 2008). The database will stay on its database server. The tests produced this problem: when the client uses Java 7, the application has NO access to the database. But when the client uses Java 8 everything works fine and the application has access to the databse. The application which is used at present on the windows 2003 server makes no problems, whatever which java version is used by the clients. The current server uses Tomcat 6, the new one Tomcat 7.
Here the log file of Tomcat7-stderr:
