Method Detail

acceptSecContext	back to summary
public byte[] acceptSecContext(InputStream is, int mechTokenLen) throws GSSException Implements sun.security.jgss.spi.GSSContextSpi.acceptSecContext. Doc from sun.security.jgss.spi.GSSContextSpi.acceptSecContext. Acceptor's context establishment call. This method may be required to be called several times. A CONTINUE_NEEDED return call indicates that more calls are needed after the next token is received from the peer. This method is called by the GSS-Framework when the application calls the acceptSecContext method on the GSSContext implementation that it has a reference to. All overloaded forms of GSSContext.acceptSecContext() can be handled with this mechanism level acceptSecContext. Since the output token from this method is a fixed size, not exceedingly large, and a one time deal, an overloaded form that takes an OutputStream has not been defined. The GSS-Framework can write the returned byte[] to any application provided OutputStream. Similarly, any application input in the form of byte arrays will be wrapped in an input stream by the GSS-Framework and then passed here. The GSS-Framework will strip off the leading mechanism independent GSS-API header. In other words, only the mechanism specific inner-context token of RFC 2743 section 3.1 will be available on the InputStream. Exceptions GSSException: may be thrown
