Exposes the remote management interface of the MLet MBean.

/** * Exposes the remote management interface of the MLet * MBean. * * @since 1.5 */
public interface MLetMBean {
Loads a text file containing MLET tags that define the MBeans to be added to the MBean server. The location of the text file is specified by a URL. The text file is read using the UTF-8 encoding. The MBeans specified in the MLET file will be instantiated and registered in the MBean server.
Params:
  • url – The URL of the text file to be loaded as String object.
Throws:
  • ServiceNotFoundException – One of the following errors has occurred: The m-let text file does not contain an MLET tag, the m-let text file is not found, a mandatory attribute of the MLET tag is not specified, the value of url is malformed.
Returns:A set containing one entry per MLET tag in the m-let text file loaded. Each entry specifies either the ObjectInstance for the created MBean, or a throwable object (that is, an error or an exception) if the MBean could not be created.

Finds the resource with the given name. A resource is some data (images, audio, text, etc) that can be accessed by class code in a way that is independent of the location of the code. The name of a resource is a "/"-separated path name that identifies the resource.
Params:
  • name – The resource name
Returns: An URL for reading the resource, or null if the resource could not be found or the caller doesn't have adequate privileges to get the resource.
