I keep getting these weird tomcat errors on shutdown on a newly built system using tomcat 7.0.57 on a windows 2012 server with jdk 1.7 that I can't figure out. This is the catalina log: Feb 12, 2015 8:54:31 AM org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc SEVERE: The web application [/identityiq] registered the JDBC driver [com.microsoft.sqlserver.jdbc.SQLServerDriver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered. Feb 12, 2015 8:54:31 AM org.apache.catalina.loader.WebappClassLoader clearReferencesThreads SEVERE: The web application [/identityiq] appears to have started a thread named [Thread-3] but has failed to stop it. This is very likely to create a memory leak.
I ran into this a while back, and it means exactly what it says: the db driver is being registered (loaded), but not being unloaded. I fixed it by putting the db driver unload commands in a contextDestroyed method.
The jdbc driver I am using is in the folder identityiq under the webapps directory in tomcat. It is the sqljdbc4.jar driver. This driver is not in the tomcat\lib directory. Please help because I am getting no help from the vender. Thank you.
