我认为 weblogic 上启用了 jmx。我有日志
<Jun 3, 2015 12:14:08 PM CEST> <Info> <Management> <BEA-141187> <Java system properties are defined as follows:

我还看到

但不可能与 Visual VM 建立连接。
在add jmx connection我尝试过
1.2.3.4:7001
1.2.3.4:8888
有或没有凭证。但结果总是相同的：cannot connect to ...
编辑
也尝试过jmap。
在本地服务器上使用 pid 可以正常工作。使用 则localhost:8888无法正常工作。
远程，jmap -permstat 1.2.3.4:888给我
