SQL JDBC Tomcat "Native Library sqljdbc_auth.dll already loaded in another classloader"

Using Microsoft's JDBC drivers to connect to a MS SQL database from Java running under Tomcat 6 with Windows Integration Authentication.

It works once, but from then until Tomcat is restarted I get a exception with the following root cause:



where "******" indicates tomcats install directory.

Both sqljdbc_auth.dll and the driver Java library sqljdbc4.jar are in Tomcat's lib directory and neither are packaged with the web applications in question.

I am making no explicit calls to load or loadLibrary, it is all being handled by sqljdbc4.jar classes.

I understand that the native library (DLL) can only be loaded into the JVM once, hence the error, but I after looking around the net I still have no solution.



Any advice would be great. Thanks.
