I have a Java Web application which stops to give response to the production environment after some interval of time in which I have used Spring framework and hibernate,
the below properties file in my project but after the deployment of project in tomcat the application runs fine for 2 to 4 days in the production but it stops giving response for the request generated by the users and me have to reload the application from tomcat and it works fine for 1 to 2 days and these tasks are done, again and again, kindly give me some suggestion that how can I resolve these issues. I have not faced these issues when I was using JDBC because the application which is developed using JDBC is running fine from last 2 yrs.
