13.4. Using the JMX Browser

Clicking the View link displays the View JMX Attributes and Operations window. Use this window to view all readable attributes exposed by the selected MBean, and alter writeable attributes. To alter an attribute's value, double-click the current value and enter the new value. If the ... button is enabled, click it to enable an advanced editor. If the attribute is a JMX object name, clicking this button displays the JMX attributes and operations for that object.

At any point, you can 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 attributes value.

You can also invoke operations upon an MBean, by selecting them from the list of operations, which is displayed below the attributes list, and clicking the Invoke button. If the operation requires parameters a further window will be displayed, from this window you must specify values for each of the parameters required. You specify parameter values in the same way as you specify JMX attribute values. Once you have specified a value for each of the parameters click the Invoke button to perform the invocation. After the invocation has completed, its return value is displayed.
