Integration Perspective - JMX

Introduction

The JMX screen is a part of the ISB Integration perspective that is integrated in the Stardust portal. It helps the user to monitor his application by checking the attributes of each managed bean and executing the operations related to them. The JMX screen offers similar functionalities as the java JConsole tool.

User Interface

Introduction

The JMX User Interface is based on JSF framework, IceFaces. It is also using an Java api to generate the attribute form. In this section we'll show some snapshots from the perspective and we'll detail every screen

Connection Forms

Once the user is logged in to the Stardust portal, he can access JMX screen by clicking on the Integration Perspective

Attribute Form

To display the attributes/operations of each managed bean, the user has to expand the corresponding nodes. Note that only the last child is a link.

When the user clicks on a link, a tabset containing the attributes and the operations related to the selected mbean is displayed.

The Attributes tab contains all the attribute names and values of the selected MBean. The attributes are displayed in a hierarchical way. This means that when the MBean contains a complex object attributes, it will be displayed as a subsection (eg: Heap Memory Usage)

Operation Form

To display the operations related to every MBean, user has only to click on the Operations tab. Then a table containing all the MBean's operations will be displayed.

To invoke an operation, the user has to clicks on it's name. Different behaviors can be noticed:

• If the operation's return type is void and the operation doesn't have parameters, a pop-up with 'Operation Invoked Successfully' is displayed.

• If the operation's parameters are not null, a pop-up is displayed in order to set the parameters values.

• If the operation's return type is different from void, a pop-up containing the result values is displayed
