                                      throws PluginException

  Override to discover servers for the server type of the plugin instance. In most cases plugins will override discoverServices rather than this method. The general use of this method is where a plugin FileServerDetector or AutoServerDetector finds the Admin server and this method discovers the managed server nodes. Such plugins include WebLogic, WebSphere and iPlanet.

  Parameters:
    `config` - Configuration of the parent server resource.
  Returns:
    List of type ServerResource
  Throws:
    `PluginException` - If an error occured during discovery.
  Since:
    1.7
  See Also:
    `discoverServices(net.hyperic.util.config.ConfigResponse)`, `ServerResource`

### discoverServices

    protected java.util.List discoverServices(ConfigResponse config)
                                       throws PluginException

  Override to discover services for the server type of the plugin instance.

  Parameters:
    `config` - Configuration of the parent server resource.
  Returns:
    List of type ServiceResource.
  Throws:
    `PluginException` - If an error occured during discovery.

### init

    public void init(PluginManager manager)
              throws PluginException

  Description copied from class: `GenericPlugin`
  Called when the plugin is loaded on the server and on the agent side.

  Overrides:
    `init` in class `GenericPlugin`
  Parameters:
    `manager` - The plugin manager for this plugin type.
  Throws:
    `PluginException`

### getManager

    protected AutoinventoryPluginManager getManager()

  Returns:
    The plugin manager for this plugin.

    public java.util.List getRegistryScanKeys()

  Helper for RegistryServerDetector implementors. Gets the scan keys from hq-plugin.xml

### getServerSignature

    public net.hyperic.hq.autoinventory.ServerSignature getServerSignature()

  The server signature is defined by plugins in etc/hq-plugin.xml if the plugin implements FileServerDetector or RegistryServerDetector.

### createServerResource

    protected ServerResource createServerResource(java.lang.String installpath)

  Initialize an ServerResource with default values. Defaults are set for:
  - Type - Using getTypeInfo().getName()
  - Name - Using getPlatformName() + " " + Type
  - InstallPath - The installpath param passed to getCanonicalPath.
  - Identifier - The installpath param.

  Parameters:
    `installpath` - Used to set InstallPath and Identifier

### createServiceResource
