So I gather that the solution was : quote The solution was to copy sqljdbc.jar to apache’s common\lib, deleting it from both web applications’ WEB-INF\lib. unquote Now maybe someone smarter than me can hasard a guess as to /why/ this would be, for the benefit of all ? Such as : Windows not liking when one establishes two separate connections to the same DB host, using the same Windows credentials ? And giving a misleading error message when one tries that ? ----- Original Message ---- My guess is that a component of the sqljdbc.jar file loads a DLL via JNI. Putting the jar file in WEB-INF/lib means that you would get multiple copies of the DLL in memory (oops). So either the code in sqljdbc.jar needs to be changed to check if the DLL is already loaded (might be a bit tricky with multiple classsloaders), or you can put sqljdbc.jar where it's only loaded once ($CATALINA_HOME/common/lib in this case). At least that's my guess . . . . . . just my two cents. /mde/ --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
