Interface MLetMBean

All Known Implementing Classes:
MLet, PrivateMLet
@Deprecated(since="20", forRemoval=true) public interface MLetMBean
Deprecated, for removal: This API element is subject to removal in a future version.
This API is part of Management Applets (m-lets), which is a legacy feature that allows loading of remote MBeans. This feature is not usable without a Security Manager, which is deprecated and subject to removal in a future release. Consequently, this API is also deprecated and subject to removal. There is no replacement.
Exposes the remote management interface of the MLet MBean.
Since:

    • getMBeansFromURL

      Set<Object> getMBeansFromURL(String url) throws ServiceNotFoundException
      Deprecated, for removal: This API element is subject to removal in a future version.
      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.
      Parameters:
      url - The URL of the text file to be loaded as String object.
      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.
      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.

    • getMBeansFromURL

      Set<Object> getMBeansFromURL(URL url) throws ServiceNotFoundException
      Deprecated, for removal: This API element is subject to removal in a future version.
      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.
      Parameters:
      url - The URL of the text file to be loaded as URL object.
      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.
      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 null.

      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.
      Parameters:
      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.

    • getResourceAsStream

      InputStream getResourceAsStream(String name)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Returns an input stream for reading the specified resource. The search order is described in the documentation for getResource(String).
      Parameters:
      name - The resource name
      Returns:
      An input stream for reading the resource, or null if the resource could not be found

    • getResources

      Enumeration<URL> getResources(String name) throws IOException
      Deprecated, for removal: This API element is subject to removal in a future version.
      Finds all the resources 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.
      Parameters:
      name - The resource name.
      Returns:
      An enumeration of URL to the resource. If no resources could be found, the enumeration will be empty. Resources that cannot be accessed will not be in the enumeration.
      Throws:
      IOException - if an I/O exception occurs when searching for resources.

    • getLibraryDirectory

      String getLibraryDirectory()

      Gets the current directory used by the library loader for storing native libraries before they are loaded into memory.
      Returns:
      The current directory used by the library loader.
      Throws:
      UnsupportedOperationException - if this implementation does not support storing native libraries in this way.
