问题 What is the MBeanServerFactory.findMBeanServer(null); exactly doing? Returns a list of all registered MBeanServers? Registered where? I am asking because I have the following problem. I have a java web app deployed in Tomcat using a service wrapper. I have custom connector implementations in my server.xml that use ManagedBeans (spring enabled). If I start the app via the service wrapper all is ok. If I start the web app through Tomcat directly it seems that the deployment breaks. All I see in

问题 Is it possible to restart tomcat via JMX? Does tomcat has any mbean that supports restart of all its apps and services? 回答1: So far as I know, there is no specific functionality to do this. However, you can install a custom MBean which will call : public static final int RESTART_EXIT_CODE = -999; .... java.lang.System.exit(RESTART_EXIT_CODE); Then modify the command file that starts the Tomcat service to check the exit code of the JVM process, and if it is equal to the RESTART_EXIT_CODE, then

问题 I have a dc/os cluster deployed to azure. I have deployed to the cluster a container with my java application. But I can't access it via jmx. Let's take the example of deploying a standart tomcat image: 1) I opened a port 8081 according the next instruction: https://docs.microsoft.com/en-us/azure/container-service/container-service-enable-public-access#open-a-port-portal. 2) I deployed service using the next json: { "id": "/tomcat", "instances": 1, "cpus": 1, "mem": 512, "container": { "type"

问题 We're using Adobe CQ (5.5) as CMS. Now, our CQ environment consists of one author server, where users can create content, and 2 publish servers which serve the content to the internet. Now there's a replication agent which pushs content from the author server to both publish server. Unfortunately some articles block the queue of the replication agents, so no more new content is beeing published. This is not much of a problem, as it is easy to fix. The real problem is that we don't notice this

问题 It was supposed to be released with Java 7, but the status is Dormant. On the other hand, the same page says Use generics in the JMX API, for example have MBeanServer.queryNames return Set<ObjectName> rather than just Set . and this did happen in Java 6.

Looking at Javadocs, I didn't notice any, but this only covers the API. 回答1: I asked this question also to the current

问题 I currently export my JMX beans using Spring and am quite happy with it.

Is there a simpler way of accessing JMX beans on an application running on WebSphere Application Server 7.0 ? 回答1: Not sure if you cannot connect to WebSphere7 JMX, or you can
