当weblogic 发生错误自动关闭后，后台日志显示错误是这样：
<2004-12-4 下午15时47分13秒 CST> <Warning> <JDBC> <BEA-001074> <A JDBC pool connection leak was detected. A connection leak occurs when a connection obtained from the pool was not closed explicitly by calling close() and then was disposed by the garbage collector and returned to the connection pool. The following stack trace at create shows where the leaked connection was created.  [Null exception passed, creating stack trace for offending caller]

怎么解决这个问题呢？在线等候...

从数据库连接池中获得的数据库连接在使用完之后得用close方法关闭，不然达到数据库连接池的连接数上限后，就会发生异常，可能也会导致服务器崩溃。
