我知道这是非常基本的，但我很沮丧。我用谷歌搜索并尝试了我能做的一切。但我无法执行此实用程序。
java utils.MulticastTest
我在 Linux open SUSE 上使用 weblogic 11g。需要在生产中复制时，我必须尽快找到它：
我也猜想（不确定）这个实用程序存在于我正在执行的 weblogic.jar 中
**linux-0m8r:/bea/Oracle/Middleware/wlserver_10.3/server/bin # ./setWLSEnv.sh**

即使在那之后当我跑步时
$ java utils.MulticastTest -N server100 -A 237.155.155.1
它给出以下错误：
linux-0m8r:/bea/Oracle/Middleware/jdk160_14_R27.6.5-32/bin # ./java utils.MulticastTest -N server100 -A 237.155.155.1

另外，我首先安装了两个 jdk，一个是操作系统，一个是与 weblogic 捆绑在一起的。尝试了两者但无法运行它..这纯粹是我可以看到的类路径问题，但我无法弄清楚如何解决它..任何帮助将不胜感激..我可以在接下来的 12 小时内使用任何问题 ..
