The displayAllAttributes() method demonstrates how to access and display the attributes of an AMX MBean.
[...] displayAllAttributes( final AMX item ) { println( "\n--- Attributes for " + item.getJ2EEType() + "=" + item.getName() + " ---" ); final Extra extra = Util.getExtra( item ); final Map attrs = extra.getAllAttributes(); final Iterator iter = attrs.keySet().iterator(); while ( iter.hasNext() ) { final String name = (String)iter.next(); final Object value = attrs.get( name ); println( name + "=" + toString( value ) ); } } public void displayAllAttributes( final String j2eeType ) { final Set items = queryForJ2EEType( j2eeType ); if ( items.size() == 0 ) { println( "No {@link AMX} of j2eeType " + SampleUtil.quote( j2eeType ) + " found" ); } else { final Iterator iter= items.iterator(); while ( iter.hasNext() ) { final AMX amx = (AMX)iter.next(); displayAllAttributes( amx ); println( "" ); } } } [...]
The displayAllAttributes() method calls the AMX.getName() and AMX.getJ2EEType() methods for an AMX MBean and prints the results onscreen. It then gets all the attributes for that MBean by calling com.sun.appserv.management.base.Extra.getAllAttributes() on the Extra instance returned by com.sun.appserv.management.base.Util.getExtra(). This is repeated for every MBean.
The attributes of AMX MBeans of a certain J2EE type can be displayed by specifying the J2EE type when the command is run. In this case, displayAllAttributes() calls queryForJ2EEType(). The queryForJ2EEType() method calls the com.sun.appserv.management.base.QueryManager.queryPropSet() method on the specified J2EE type to identify all elements of that type in the domain.
