public class RMIConnectorServer
extends JMXConnectorServer
```
A JMX API connector server that creates RMI-based connections from remote clients. Usually, such connector servers are made using JMXConnectorServerFactory. However, specialized applications can use this class directly, for example with an RMIServerImpl object.

  - SERIAL_FILTER_PATTERN
```
public static final String SERIAL_FILTER_PATTERN
```
    This attribute defines a pattern from which to create a ObjectInputFilter that will be used when deserializing objects sent to the JMXConnectorServer by any client.
    The filter will be called for any class found in the serialized stream sent to server by client, including all JMX defined classes (such as ObjectName), all method parameters, and, if present in the stream, all classes transitively referred by the serial form of any deserialized object. The pattern must be in same format as used in ObjectInputFilter.Config.createFilter(java.lang.String). It may define a white list of permitted classes, a black list of rejected classes, a maximum depth for the deserialized objects, etc.
    To be functional, the filter should allow at least all the concrete types in the transitive closure of all objects that might get serialized when serializing all JMX classes referred as parameters in the RMIConnection interface, plus all classes that a client might need to transmit wrapped in marshalled objects in order to interoperate with the MBeans registered in the MBeanServer. That would potentially include all the concrete JMX OpenTypes and the classes they use in their serial form.
    Care must be taken when defining such a filter, as defining a white list too restrictive or a too wide a black list may prevent legitimate clients from interoperating with the JMXConnectorServer.

                   throws IOException
```
    Makes an RMIConnectorServer. This is equivalent to calling RMIConnectorServer(directoryURL,environment,null,null)
    
    Parameters:
    
    url - the URL defining how to create the connector server. Cannot be null.

    rmiServerImpl - An implementation of the RMIServer interface, consistent with the protocol type specified in url. If this parameter is non null, the protocol type specified by url is not constrained, and is assumed to be valid. Otherwise, only "rmi" will be recognized.
    
    mbeanServer - the MBean server to which the new connector server is attached, or null if it will be attached by being registered as an MBean in the MBean server.
    
    Throws:
    
    IllegalArgumentException - if url is null.
    
    MalformedURLException - if url does not conform to the syntax for an RMI connector, or if its protocol is not recognized by this implementation. Only "rmi" is recognized when rmiServerImpl is null.

public JMXConnector toJMXConnector(Map<String,?> env)
                            throws IOException
```
    Returns a client stub for this connector server. A client stub is a serializable object whose connect method can be used to make one new connection to this connector server.
    
    Specified by:
    
    toJMXConnector in interface JMXConnectorServerMBean
    
    Overrides:
    
    toJMXConnector in class JMXConnectorServer
    
    Parameters:
    
    env - client connection parameters of the same sort that could be provided to JMXConnector.connect(Map). Can be null, which is equivalent to an empty map.
    
    Returns:
    
    a client stub that can be used to make a new connection to this connector server.
    
    Throws:
    
    UnsupportedOperationException - if this connector server does not support the generation of client stubs.
    
    IllegalStateException - if the JMXConnectorServer is not started (see JMXConnectorServerMBean.isActive()).
    
    IOException - if a communications problem means that a stub cannot be created.
  - start
```
public void start()
           throws IOException
```
    Activates the connector server, that is starts listening for client connections. Calling this method when the connector server is already active has no effect. Calling this method when the connector server has been stopped will generate an IOException.
    
    The behavior of this method when called for the first time depends on the parameters that were supplied at construction, as described below.
    
    First, an object of a subclass of RMIServerImpl is required, to export the connector server through RMI:
    
    If an RMIServerImpl was supplied to the constructor, it is used.
    Otherwise, if the JMXServiceURL was null, or its protocol part was rmi, an object of type RMIJRMPServerImpl is created.
    Otherwise, the implementation can create an implementation-specific RMIServerImpl or it can throw MalformedURLException.
    
    If the given address includes a JNDI directory URL as specified in the package documentation for javax.management.remote.rmi, then this RMIConnectorServer will bootstrap by binding the RMIServerImpl to the given address.
    
    If the URL path part of the JMXServiceURL was empty or a single slash (/), then the RMI object will not be bound to a directory. Instead, a reference to it will be encoded in the URL path of the RMIConnectorServer address (returned by JMXConnectorServerMBean.getAddress()). The encodings for rmi are described in the package documentation for javax.management.remote.rmi.
    
    The behavior when the URL path is neither empty nor a JNDI directory URL, or when the protocol is not rmi, is implementation defined, and may include throwing MalformedURLException when the connector server is created or when it is started.
    Throws:
    
    IllegalStateException - if the connector server has not been attached to an MBean server.
    
    IOException - if the connector server cannot be started.
  - stop
```
public void stop()
          throws IOException
```
    Deactivates the connector server, that is, stops listening for client connections. Calling this method will also close all client connections that were made by this server. After this method returns, whether normally or with an exception, the connector server will not create any new client connections.
    
    Once a connector server has been stopped, it cannot be started again.
    
    Calling this method when the connector server has already been stopped has no effect. Calling this method when the connector server has not yet been started will disable the connector server object permanently.
    
    If closing a client connection produces an exception, that exception is not thrown from this method. A JMXConnectionNotification is emitted from this MBean with the connection ID of the connection that could not be closed.
    
    Closing a connector server is a potentially slow operation. For example, if a client machine with an open connection has crashed, the close operation might have to wait for a network protocol timeout. Callers that do not want to block in a close operation should do it in a separate thread.
    
    This method calls the method close on the connector server's RMIServerImpl object.
    
    If the RMIServerImpl was bound to a JNDI directory by the start method, it is unbound from the directory by this method.
    
    Throws:
    
    IOException - if the server cannot be closed cleanly, or if the RMIServerImpl cannot be unbound from the directory. When this exception is thrown, the server has already attempted to close all client connections, if appropriate; to call RMIServerImpl.close(); and to unbind the RMIServerImpl from its directory, if appropriate. All client connections are closed except possibly those that generated exceptions when the server attempted to close them.
