我正在使用下面的 java 程序连接到这个队列。

在这里提问...
一个。 JNDI_FACTORY、JMS_FACTORY、QUEUE、url 中的值应该是什么，它们表示什么？
b. url 中的 't3://' 是什么意思？这是协议吗？如果可以，主动MQ应该给什么？

当我使用下面的代码时，出现以下错误。我附上了我的 activeMQ 队列详细信息的图像。我知道我使用的 URL 是错误的。你能帮我找到合适的吗？

希望这对您有所帮助..
我已将 JMS 服务器名称作为参数传递。并且应该导入 WLS 库 jar

TopicPublisher sender = session.createPublisher(topic);
JNDI_FACTORY 更像是您要用于连接的驱动程序，它们通常特定于供应商，在您的情况下是 weblogic 并且是预定义的。
JMS_FACTORY 是您已经在 Web 逻辑中为此类集成预定义的连接工厂。它负责管理与队列的连接。
QUEUE 也是您需要在 weblogic 管理控制台上预定义/设置的东西。它是对驻留在您事先设置的 weblogic 上的队列的引用。
t3 是您正在使用的连接类型，另一种选择可能是 iiop。 t3 它是一种更轻量级的连接类型。
