这是放置外部罐子的正确路径吗?

is this the correct path to put the external jars??

推荐答案

这要视情况而定.谁在实际创建连接?如果您的应用程序代码是直接的，则JAR属于WEB-INF/lib.如果您的容器通过JNDI资源管理连接，则JAR必须位于 Glassfish 类路径中，而不是WEB-INF/lib中.

It depends. Who is actually creating the connection? If your application code is directly, then the JAR belongs in WEB-INF/lib. If your container is managing the connections through a JNDI resource, then the JAR needs to be in the Glassfish classpath, not WEB-INF/lib.

在Glassfish 3.x中，我将JAR放在domain/lib/ext或类似的东西中.

In Glassfish 3.x I put the JARs in domain/lib/ext or something like that.
