JMX access WEBLOGIC9.2

JMX access WEBLOGIC9.2

Development environment as well as the reference packet
weblogic9.0 running on JDK5.0 or higher than the 5.0 version.
JAR package reference:
Only need to introduce weblogic .jar can be had, weblogic9.2's JAR size is about 51.4 MB.
Do not need the introduction of JMX packages , such as mx4j.jar

Open Pre-development process:
A good programming practice is conducive to this end, we will be some commonly used parameters extracted, placed in a separate class, are as follows:

Maybe you have discovered, and 9.2 parameters have been many more than the 7.0, so many parameters does it mean that 9.2 of the access method as opposed to 7.0 of the access methods and sampling method is different from that seen it.
9.2 The access methods are mainly based MbeanServerConnection this class there were also some MbeanHome of methods, such as queryMBeans (parameter 1, parameter 2), as MbeanHome, 9.2 inside, has been marked as obsolete.
Here we will JMX way to access weblogic9.2.

The same is by visiting queryMBeans method, we can also get Set encapsulated data, but these Set the type of data encapsulation and 7.0 but not the same, who are interested can track what the data type of all ObjectInstance, so we value also can not use the previous approach to value, and needs the Attribute class to value, is obtained from the ObjectInstance, you can get through the following ways
ExecuteThread [] executeThreads = (ExecuteThread []) mscon.getAttribute (objectIns.getObjectName (), Constant.ExecuteThreads)
You can also enter a series of attributes to return to the AttributeList, and then an iterative way, one by one to obtain the name and the value of each Attribute
AttributeList aList = mscon.getAttributes (objectIns.getObjectName (), Constant.THREAD_ATTRIBUTES);
