Jboss 4.0.5多个jdbc驱动程序

Question

我可以将多个Jdbc驱动程序（例如mysql postgres等）加载到应用程序服务器并使用适合每个数据库的程序吗？ 我有jboss 4.0.5GA，我把postgress jdbc驱动程序放在/ server / lib里，那里也有oracle jdbc。事情是，只有我删除jdbc3（oracle）驱动程序postgres工作但是如果我不删除它jboss使用PostgreSQL Native Driver。有什么想法？ 这是我的postgres-ds.xml

事情就是jboss说：JDBC驱动程序：PostgreSQL Native Driver，版本：PostgreSQL 7.3.4 JDBC3 jdbc驱动程序构建113但是调用displayClassInfo（）显示/C:/jboss-4.0.5.GA/server/remedy/ lib / postgresql-9.3-1102.jdbc3.jar。我如何强制使用加载的驱动程序??????
