where does wildfly store jdbc driver jar file?

I'm using wildfly 8.2. I registered the sqlite driver and created a datasource for it already. It's connected fine and I can see it in the standalone.xml.

But when I search under the "wildfly-8.2.0.Final" directory, I can't find the "sqlite-jdbc-3.8.7.jar" file.

Do you know where wildfly store the physical jar file?

Thanks
