I used it for years if it can help:
public static void main(String[] a) throws Exception {
if (a.length != 2) {
System.out.println("put the objectname name as parameter:
<program> <host> <port>");
return;
}
JMXServiceURL url = new
JMXServiceURL("service:jmx:rmi:///jndi/rmi://" + a[0] + ":" + a[1] +
"/jmxrmi");
JMXConnector jmxc = JMXConnectorFactory.connect(url);
MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();
Set<ObjectName> names = mbsc.queryNames(null, null);
for (ObjectName on : names) {
MBeanInfo infos = mbsc.getMBeanInfo(on);
System.out.println(on.getCanonicalName());
System.out.println("====================");
for (MBeanAttributeInfo info : infos.getAttributes()) {
String name = info.getName();
Object value;
try {
value = mbsc.getAttribute(on, name);
System.out.println("\t" + name + " = " + getValue(value));
} catch (Exception e) {
System.out.println("\t" + name + " = [unable to
get this attribute: " + e.getMessage() + "]");
}
}
System.out.println();
System.out.println();
}
}
private static String getValue(Object value) {
if (value instanceof Object[]) {
return getArrayValue((Object[]) value);
}
if (value.getClass().getName().startsWith("java.lang")) {
return value.toString();
}
if (value instanceof CompositeData) {
CompositeData datas = (CompositeData) value;
return datas.values().toString();
}
if (!(value instanceof String)) {
return new ToStringBuilder(value).toString();
}
return (String) value;
}
private static String getArrayValue(Object[] value) {
String[] strs = new String[value.length];
for (int i = 0; i < strs.length; i++) {
strs[i] = getValue(value[i]);
}
return Arrays.asList(strs).toString();
}
