Hi I have deployed an application in Apache tomcat 7.59.
When I copy the war to webapps folder and start tomcat. Tomcat hangs and I coudln't see the admin screen as well for the first 30 minutes. Without this war, tomcat starts fine shows the admin screen immediately. Through google, I check a posts, which asked me to take a thread dump. I use Sprint, Hibernate and Mysql. From the thread dump, I could see that and could also see that the problem with the connectivity to MySQL. But I am not sure where exactly the problem lies and what needs to be fixed. Any help is appreciated!!
