AdminClient invoke on Mbean error
kame...@yahoo.com
i am trying to invoke getChildren() method in Discovery MBean
in was
----------------------------------------------------------------------------
String query = "WebSphere:*,type=Discovery";
ObjectName queryName = new ObjectName(query);
Set s = _soapClient.queryNames(queryName, null);
if (!s.isEmpty()){
discoverybean= (ObjectName)s.iterator().next();
System.out.println("DiscoveryBean found" +discoverybean.toString());
}
else{
System.out.println("DiscoveryBean not found" );
}
------------------------------------------------------------------------------
try{
childprocesslist =(java.util.List)_soapClient.invoke (discoverybean,"getChildren", new Object[] {}, new String[] {});
}
catch (Exception e)
{
System.out.println("Exception invoking launchProcess: " + e);
}
------------------------------------------------------------------------------
error
DiscoveryBean found WebSphere:platform=common,cell=195al-purifyNetwork,version=5.0,name=Discovery,mbeanIdentifier=Discovery,type=Discovery,node=195al-purify,process=nodeagent
Exception invoking launchProcess: com.ibm.websphere.management.exception.ConnectorException: ADMC0009E: Failed to make the SOAP RPC call: invoke
-------------------------------------------------------------------------------------------
if i pass empty string in params and signature as fallows :
childprocesslist =(java.util.List)_soapClient.invoke (discoverybean,"getChildren", new Object[] {""}, new String[] {""});
its throwing fallowing error :
Exception invoking launchProcess: javax.management.RuntimeOperationsException: JMXmd0011E Operation getChildren not found
can any one help me out
thanks in advance
Ken Hygh
try this syntax if your operation doesn't take parameters:
try{
childprocesslist =(java.util.List)_soapClient.invoke (discoverybean,"getChildren",null, null);
}
catch (Exception e)
{
System.out.println("Exception invoking launchProcess: " + e);
}

It is _very_ unusual to connect to a node agent - your changes will be
overwritten by the next synch from the Deployment Manager. You typically
want to connect to the DM.

Exception invoking Discovery: javax.management.RuntimeOperationsException: JMXmd0011E Operation getChildren not found
sorry for not being clear in my presentation;-
error at AppManagement i am not getting may be port address u need to give appropriate one the one i have given may not be valid!
regarding looking at nodeagent comment in the debugging statement i mentioned by mistake as nodeagent actually i am looking at DM level only
thanks
Ken Hygh
There is no standard MBean with type=Discovery in version 6. What
version are you using?
Ken
kame...@yahoo.com
2) as well i am curious about the error u got(AppManager not found exception ) while running my code ,when i tried on my friends system i faced about the same problem if i run on my machine no problems and the version of WAS on both of our systems same ?
Ken Hygh
>1) i am using version 5.1 i could see the MBean in MBean inspector is it the same as i seen in MBean inspector ?

Sorry, I don't have a 5.1 system I can easily play with.
Check the port numbers between your system and your friend's - you may
be connecting to app servers vs. node agents vs. DM's.
