/**
 * <p>Socket factory for SSL jndi links that returns an SSL socket.
 * It incorporates a keystore, which must contain the certs used
 * to authenticate the client.</p>
 *
 * <p>This code is based on sample code made freely available by author
 * Spencer W. Thomas on his web site http://hubris.engin.umich.edu/java/
 * On Wed 24 May, 2000.</p>
 *
 * <p><b>Warning</b></p>
 *
 * <p>This class relies heavily on an internal, single, static SSLSocketFactory.
 * multiple objects of this type in fact will use the same internal SSLSocketFactory.
 * (This is why a single static init() method sets up everything for the entire
 * class.)  The reason for this structure is that JndiSocketFactory is dynmaically
 * invoked by the jndi connection, and we have no other chance to initialise the
 * object.</p>
