Attributes and Operations
When you click the View link, the View JMX Attributes and Operations window appears. You can view all readable attributes exposed by the selected MBean. You can also alter writable attributes. If an attribute is read-only then you cannot alter an attribute's value. To alter an attribute's value, just double-click the current value and enter the new value. If the Edit button is enabled, then you can click it to open an advanced editor. If the attribute type is a JMX object name, clicking this button displays the JMX attributes and operations for the object. Click the Refresh button to refresh the attribute values. If an exception occurs while retrieving the value of an attribute, the exception is displayed in place of the attribute's value. You can also invoke operations upon an MBean. A list of operations exposed by an MBean is displayed below the attributes list. To invoke an operation, select it from the list and click the Invoke button. If the operation requires parameters, a window will be displayed, prompting you for the values. You specify parameter values in the same way as you specify JMX attribute values. After you have specified a value for each of the parameters, click the Invoke button to perform the invocation. After the method invocation is complete, its return value is displayed.
