Getting a threadlocal error while deploying to tomcat

I have problem in deploying a grails project to the tomcat webapp directory.

Looking into the catalina.out log file I can see the following error:

SEVERE: The web application [/test-0.1] 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.
Dec 24, 2012 10:41:52 AM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
SEVERE: The web application [/test-0.1] created a ThreadLocal with key of type [org.codehaus.groovy.grails.commons.spring.ReloadAwareAutowireCapableBeanFactory$2] (value [org.codehaus.groovy.grails.commons.spring.ReloadAwareAutowireCapableBeanFactory$2@57390ad3]) and a value of type [java.lang.Boolean] (value [false]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.

I'm very new to Tomcat and not sure what these errors mean. Kindly help me out.

Thanks in advance.

Did the JDBC Driver exist on your classpath ?

To fix that, create a folder lib on your jquery plugin

e.g ~/.grails/2.1.0/projects/YourProject/plugins/jquery-1.x.x/lib

and copy the JDBC Driver jar on this folder.

Hope this help.

Copy the JDBC driver jar file to tomcat/lib directory would solve this issue.
