I can connect the remote/local jboss sever by using %JBOSS_HOME%/bin/jconsole.bat. In jconsole , I can do dumpAllThreads operation and get the right result.
However , when I use java code with the MBeanServerConnection interface to dumpAllThreads(boolean,boolean) or getThreadInfo(long[], boolean, boolean), I got Exception:
The java code is :
MBeanServerConnection scon = con.getMBeanServerConnection();
ObjectName oname = new ObjectName(ManagementFactory.THREAD_MXBEAN_NAME);
Object obj = scon.invoke(oname, "dumpAllThreads", new Object[]{true,false}, new String[]{"java.lang.String","java.lang.String"});
or
ThreadMXBean mx = ManagementFactory.newPlatformMXBeanProxy(scon,ManagementFactory.THREAD_MXBEAN_NAME, ThreadMXBean.class);
ThreadInfo[] txx = mx.dumpAllThreads(true, false);
Exception:
Exception in thread "main" java.lang.RuntimeException: Operation failed with status WAITING
at org.jboss.remoting3.jmx.RemotingConnector.connect(RemotingConnector.java:155)
at javax.management.remote.JMXConnectorFactory.connect(JMXConnectorFactory.java:267)
Environment
jboss as7,jdk7
NOTE
ThreadInfo t = mx.getThreadInfo(l,200) and any other mxbean such as MemoryPoolMXBean will be ok.
Do you have this kind of situation？
If any other configurations should be done before jmx in jboss as7?
Thanks you in advance.
