What is MBeanInspector for WebSphere Application Server?
MBeanInspector for WebSphere® Application Server is a Java™ Management Extensions (JMX)-based administration program for WebSphere 5. MBeanInspector can connect to WebSphere servers and inspect the JMX Management Beans (MBeans) that are registered with that server.
MBeanInspector is particularly useful to the WebSphere development community as a testing tool. In this same capacity, it is useful to customers deploying custom MBeans on their WebSphere 5 servers.
MBeanInspector allows users to examine MBean attributes, invoke MBean operations, and listen for MBean notifications. If connected to a Deployment Manager, MBeanInspector will present MBeans using the topology of the host cell.
How does it work? WebSphere 5 servers (Deployment Manager, Node Agent, Application Server) all contain a JMX MBean server. MBeanInspector uses WebSphere's AdminClient API to connect to these MBean servers and inspect the three types of data that MBeans expose: attributes, operations, and notifications.
MBean attributes are analogous to public members on a regular Java bean: They can be gotten and set directly without using an accessor method. MBeanInspector supports getting MBean attributes from attribute detail panels. Setting attributes is not currently supported.
MBean operations are analogous to public methods on a regular Java bean: They can take a list of parameters and return a result. MBeanInspector currently supports the invoking of MBean operations that accept a commonly used set of parameter types, including all Java primitives, primitive wrappers, typed arrays, java.lang.String, java.util.Properties, and com.ibm.websphere.management.filetransfer.client.FileTransferOptions.
MBean notifications are analogous to events broadcast by a regular Java bean. MBeanInspector can listen for any type of notification, including custom types used by WebSphere.
