I am building a GWT application that queries SQL Server. While working in Eclipse everything is fine and dandy, but when I try to deploy a .war file and stick it into a JBoss deployments directory, I get this error:

Failed to load the sqljdbc_auth.dll cause : Native Library JBossServerPath\bin\sqljdbc_auth.dll already loaded in another classloader com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication. ClientConnectionId:450886fa-8bde-4f52-b213-7af1f4948913

If I remove the sqljdbc4.jar from my project directory and have the sqljdbc_auth.dll in the JBossPath\bin directory as suggested here, I get the following error.

java.sql.SQLException: No suitable driver found for jdbc:sqlserver://localhost:1433;databaseName=DataBase;integratedSecurity=true;

Also, I can't find the lib directory referenced in the above answer.

I have the sqljdbc4.jar in my project's WEB-INF\lib directory and I'm building the project with ant.

I tried asking this question earlier, but it got marked as a duplicate of this question, which did not solve my problem.

The issue was I didn't have the line Dependencies: com.microsoft.sqlserver in my Manifest.MF file.
