mbeans

问题 Suppose we have a MBean that has the following attributes and operations. Attributes: name size Operations: getName() getSize() Is there a way to programmatically check for the attributes and operations? I've been working with the IBM WebSphere MBeans and their documentation isn't very good. For example, if you go to IBMs Infocenter and navigate to Network Deployment -> Reference -> Programming interfaces -> Mbean interfaces -> ThreadPool. They only have attributes listed and no operations.

问题 Basically I'm trying to modify the code from this tutorial here: http://docs.oracle.com/javase/tutorial/jmx/remote/custom.html so that I can access the MBeans from tomcat that are described here: http://wiki.apache.org/tomcat/FAQ/Monitoring there is no problem accessing the JMX Bean java.lang:type=Memory from code since it's interface is defined in java.lang. Here's the code example of that: ObjectName mbeanName = new ObjectName("java.lang:type=Memory"); MemoryMXBean mxbeanProxy2 = JMX

问题 I want to move a startup MBEAN file (startup-client-service.xml) from my EJB > META-INF , to EAR > META-INF folder. I tried with the maven-resources-plugin plugin but it just copy the file from EJB > META-INF to Target in ear folder. But in built ear the startup-client-service.xml file is not available in META-INF How can I move my startup file to META-INF into ear > META-INF ? This is the pom file of ear. <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0

问题 I have implemented JMXAuthenticator for JMX authentication over RMI, however I am not sure how to create roles to allow for readonly/readwrite access levels. For example, in JMXAuthenticator.authenticate I have my custom authentication logic and want this to determine the access role. I have tried the following but it makes no difference when performing operations in JConsole: @Override public Subject authenticate(Object credentials) { Subject subject = new Subject(); JMXPrincipal p; //...my

问题 From the documentation of oracle : Domain Runtime MBean Server : This MBean server also acts as a single point of access for MBeans that reside on Managed Servers. what i want to do is to use this fact to access all my custom mBeans scattered in several managed servers. for example assume that i have two nodes server-1 server-2 . how can i access all of the custom mBeans on both server-1 server-2 by connecting to the administrator node ? i dont want to remotly access each node to return the

问题 At startup we need to get the server address and the http port of the running application. Until now we made it like this: MBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer(); ObjectName socketBindingMBean = new ObjectName("jboss.as:socket-binding-group=standard-sockets,socket-binding=http"); String host = (String) mBeanServer.getAttribute(socketBindingMBean, "boundAddress"), Integer port = (Integer) mBeanServer.getAttribute(socketBindingMBean, "boundPort")); Everything was

问题 I am running a client/server application using JBoss. How can I connect to the server JVM's MBeanServer? I want to use the MemoryMX MBean to track the memory consumption. I can connect to the JBoss MBeanServer using JNDI lookup but the java.lang.MemoryMX MBean is not registered with the JBoss MBeanServer. EDIT: The requirement is for programmatic access to the memory usage from the client. 回答1: Unlike the JBoss server's MBeanServer, the JVM's MBean server doesn't allow remote monitoring by

问题 I am migrating a legacy code to java 8 and after changing the Spring version to 3.2.10.RELEASE and deploying it on jboss 4.2.3 I am getting: 2014-09-02 05:57:57,396 ERROR [org.jboss.deployment.MainDeployer] Could not create deployment: file:/project/SA/opt/jboss-4.2.3.GA/server/sa/deploy/sa/sa-pmt-service-1.0.4-SNAPSHOT-dev.sar org.jboss.deployment.DeploymentException: MBean attribute 'name' must be given. at org.jboss.system.ServiceConfigurator.parseObjectName(ServiceConfigurator.java:783)

问题 My app runs well on Worklight Development Server, but not on WebSphere Application Server V8.5 Liberty Profile. I tried both Oracle JDK and IBM JDK, there was no difference. There was no problem connecting to the server with jconsole, although I had to connect without ssl.

问题 I'm trying to access the JBoss v4.2 MBean registered as jboss.web:type=Manager,path=/,host=localhost using the following code: ObjectName name = new ObjectName("jboss.web:type=Manager,path=/,host=localhost"); ManagementFactory.getPlatformMBeanServer().getAttribute(name, "activeSessions"); But this code keeps throwing the following exception: javax.management.InstanceNotFoundException : jboss.web:type=Manager,path=/,host=localhost is not registered. On the other hand I'm able to see and use
