Use JMX to dynamically configure it for WebLogic (source code)

Configuring WebLogic is generally configured by the Console console, but sometimes you need to make dynamic configurations in the program, such as adding queues, display queues, or configuring data sources; rewrote writing config.xml, is The effect of dynamic configuration can be reached, but the BEA does not recommend this, and doing so need to restart the server. How is it dynamic configuration, don't restart the server? The author queries WebLogic website and learned that there are two ways to dynamically configure (1) can use the weblogic.admin command (document address: http://e-docs.bea.com/wls/docs81/pdf/adminguide.pdf ), (2) Use WebLogic to be programmed with JMX, and dynamically configure the components in WebLogic by JMX. JMX document address: http://e-docs.bea.com/wls/docs81/pdf/jmx.pdf, if you use this method, you should configure WebLogic.jar into the ClassPath environment variable (because WebLogic JMX class Is put in WebLogic.jar)

I wrote a code, manage Queue, including JMSQueue, delete, and display, my config.xml file is as follows:???

??????? Targets = "myserver" TempoRyTemplate = "MyjmsTemplate">

???????

??????????? name = "centerqueue" template = "myjmstemplate" />

???????

??????????? name = "que00001" template = "myjmstemplate" />

???????

??????????? name = "que00002" Template = "myjmstemplate" />

???????

???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

The code is as follows: package messagecenter;
