I have a question in reference to Apache Tomcat. I thought I knew what the issue was, but I will ask anyone who knows as a reference.
I am working on a web application that makes numerous database calls for information manipulation. The application is connected to a MySQL server via straight jdbc.
I have checked and may have possibly missed, but all of my resultSets, statements, and connections are closed when the methods are completed as far as I can tell. Yet, I get this recurring and troubling message from tomcat every time. The message is as follows:
SEVERE: The web application [/myApplication] registered the JDBC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered. Sep 11, 2013 12:33:40 PM org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
SEVERE: The web application [/myApplication] appears to have started a thread named [Abandoned connection cleanup thread] but has failed to stop it. This is very likely to create a memory leak. Sep 11, 2013 12:33:40 PM org.apache.catalina.core.StandardContext reload.
If anyone has any insight into exactly what this this issue is, it would be most appreciated. If it helps, I have connections to 4 different databases within the MySQL database, I don't known whether or not that makes a difference, but just throwing it out there.
Thanks all.
