javax.rmi.ssl.SslRMIServerSocketFactory

All Implemented Interfaces:

RMIServerSocketFactory

public class SslRMIServerSocketFactory
extends Object
implements RMIServerSocketFactory

An SslRMIServerSocketFactory instance is used by the RMI runtime in order to obtain server sockets for RMI calls via SSL.

This class implements RMIServerSocketFactory over the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocols.

This class creates SSL sockets using the default SSLSocketFactory (see SSLSocketFactory.getDefault()) or the default SSLServerSocketFactory (see SSLServerSocketFactory.getDefault()) unless the constructor taking an SSLContext is used in which case the SSL sockets are created using the SSLSocketFactory returned by SSLContext.getSocketFactory() or the SSLServerSocketFactory returned by SSLContext.getServerSocketFactory(). When an SSLContext is not supplied all the instances of this class share the same keystore, and the same truststore (when client authentication is required by the server). This behavior can be modified by supplying an already initialized SSLContext instance.

Constructor Details

SslRMIServerSocketFactory

public SslRMIServerSocketFactory()

Creates a new SslRMIServerSocketFactory with the default SSL socket configuration.

SSL connections accepted by server sockets created by this factory have the default cipher suites and protocol versions enabled and do not require client authentication.

SslRMIServerSocketFactory

public SslRMIServerSocketFactory(String[] enabledCipherSuites,
 String[] enabledProtocols,
 boolean needClientAuth)
                          throws IllegalArgumentException

Creates a new SslRMIServerSocketFactory with the specified SSL socket configuration.

Parameters:

enabledCipherSuites - names of all the cipher suites to enable on SSL connections accepted by server sockets created by this factory, or null to use the cipher suites that are enabled by default

enabledProtocols - names of all the protocol versions to enable on SSL connections accepted by server sockets created by this factory, or null to use the protocol versions that are enabled by default

needClientAuth - true to require client authentication on SSL connections accepted by server sockets created by this factory; false to not require client authentication

Throws:

IllegalArgumentException - when one or more of the cipher suites named by the enabledCipherSuites parameter is not supported, when one or more of the protocols named by the enabledProtocols parameter is not supported or when a problem is encountered while trying to check if the supplied cipher suites and protocols to be enabled are supported.

• SSLSocket.setEnabledCipherSuites(java.lang.String[])
• SSLSocket.setEnabledProtocols(java.lang.String[])
• SSLSocket.setNeedClientAuth(boolean)

SslRMIServerSocketFactory

public SslRMIServerSocketFactory(SSLContext context,
 String[] enabledCipherSuites,
 String[] enabledProtocols,
 boolean needClientAuth)
                          throws IllegalArgumentException

Creates a new SslRMIServerSocketFactory with the specified SSLContext and SSL socket configuration.

Parameters:

context - the SSL context to be used for creating SSL sockets. If context is null the default SSLSocketFactory or the default SSLServerSocketFactory will be used to create SSL sockets. Otherwise, the socket factory returned by SSLContext.getSocketFactory() or SSLContext.getServerSocketFactory() will be used instead.

enabledCipherSuites - names of all the cipher suites to enable on SSL connections accepted by server sockets created by this factory, or null to use the cipher suites that are enabled by default

enabledProtocols - names of all the protocol versions to enable on SSL connections accepted by server sockets created by this factory, or null to use the protocol versions that are enabled by default

needClientAuth - true to require client authentication on SSL connections accepted by server sockets created by this factory; false to not require client authentication

Throws:

IllegalArgumentException - when one or more of the cipher suites named by the enabledCipherSuites parameter is not supported, when one or more of the protocols named by the enabledProtocols parameter is not supported or when a problem is encountered while trying to check if the supplied cipher suites and protocols to be enabled are supported.

Method Details

getEnabledCipherSuites

public final String[] getEnabledCipherSuites()

Returns the names of the cipher suites enabled on SSL connections accepted by server sockets created by this factory, or null if this factory uses the cipher suites that are enabled by default.

Returns:

an array of cipher suites enabled, or null

See Also:

• SSLSocket.setEnabledCipherSuites(java.lang.String[])

getEnabledProtocols

public final String[] getEnabledProtocols()

Returns the names of the protocol versions enabled on SSL connections accepted by server sockets created by this factory, or null if this factory uses the protocol versions that are enabled by default.

Returns:

an array of protocol versions enabled, or null

See Also:

• SSLSocket.setEnabledProtocols(java.lang.String[])

getNeedClientAuth

public final boolean getNeedClientAuth()

Returns true if client authentication is required on SSL connections accepted by server sockets created by this factory.

Returns:

true if client authentication is required

See Also:

• SSLSocket.setNeedClientAuth(boolean)

createServerSocket

public ServerSocket createServerSocket(int port)
                                throws IOException

Creates a server socket that accepts SSL connections configured according to this factory's SSL socket configuration parameters.

Specified by:

createServerSocket in interface RMIServerSocketFactory

Parameters:

port - the port number

Returns:

the server socket on the specified port

Throws:

IOException - if an I/O error occurs during server socket creation

equals

public boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

Two SslRMIServerSocketFactory objects are equal if they have been constructed with the same SSL context and SSL socket configuration parameters.

A subclass should override this method (as well as hashCode()) if it adds instance state that affects equality.

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

• Object.hashCode()
• HashMap

hashCode

public int hashCode()

Returns a hash code value for this SslRMIServerSocketFactory.

Overrides:

hashCode in class Object

Returns:

a hash code value for this SslRMIServerSocketFactory.
