Examples of org.ietf.jgss.GSSManager.createName()

org.ietf.jgss.GSSManager.createName()
Factory method to convert a string name from the specified namespace to a GSSName object. In general, the GSSName object created will contain multiple representations of the name, one for each mechanism that is supported; two examples that are exceptions to this are when the namespace type parameter indicates NT_EXPORT_NAME or when the GSS-API implementation is not multi-mechanism. It is not recommended to use this method with a NT_EXPORT_NAME type because representing a previously exported name consisting of abitrary bytes as a String might cause problems with character encoding schemes. In such cases it is recommended that the bytes be passed in directly to the overloaded form of this method {@link #createName(byte[],Oid) createName}. @param nameStr the string representing a printable form of the name tocreate. @param nameType the Oid specifying the namespace of the printable namesupplied. null can be used to specify that a mechanism specific default printable syntax should be assumed by each mechanism that examines nameStr. It is not advisable to use the nametype NT_EXPORT_NAME with this method. @return a GSSName representing the indicated principal @see GSSName @see GSSName#NT_EXPORT_NAME @throws GSSException containing the following major error codes: {@link GSSException#BAD_NAMETYPE GSSException.BAD_NAMETYPE}, {@link GSSException#BAD_NAME GSSException.BAD_NAME}, {@link GSSException#BAD_MECH GSSException.BAD_MECH}, {@link GSSException#FAILURE GSSException.FAILURE}
