Secure transport gateway for message queuing and transport over an open network
A system provides for the secure exchanging files with a remote transfer server over an open network such as the Internet. The system comprises a database storing file transfer parameters in association with identification of a remote file transfer client. The file transfer parameters include object destination parameters defining a processing call to a transfer server message queuing manager operating in conjunction with the transfer server. The processing call provides for delivery of the binary object to the transfer server message queuing manager in conjunction with a destination queue definition which provides for queuing the binary object within the defined queue for retrieval by a destination application. A transfer application coupled to the database comprises a plurality of file transfer methods available to remote file transfer clients making method calls thereto. The plurality of transfer methods comprise: i) an event definition method for providing to the remote transfer client the file transfer event parameters that are associated with the remote transfer client in response to receiving a method call from the remote transfer client; ii) an upload method for storing a binary object in a binary storage in response to receiving a method call from the remote transfer client that includes the binary object; and iii) a destination method for executing a processing call to the transfer server message queuing manager in response to receiving a method call from the remote transfer client that includes the object destination parameters, the processing call delivering the binary object from the binary storage to the transfer server method queuing manager in conjunction with the destination queue definition.

obtaining, the identification of the remote transfer client associated with the session ID included in the method call;
obtaining, from the event key table, the event key value associated with the identification of the remote transfer client; and
providing a response message to the transfer client, the response message including the event key value associated with identification of the remote transfer client;
a read event method executed in response to receiving a read event method call from the remote transfer client, the read event method call comprising the session ID and the event key value; the read event method comprising:
retrieving the event parameters associated with the event key value included in the method call from the event parameter table, and
returning a response message to the transfer client, the response message comprising the MQ Get Parameter and the MQ Put Parameter;
an upload method operated in response to receiving an upload method call from the remote file transfer client, the upload method call comprising the session ID, a file name, and the binary object, the upload method comprising;
generating an object ID to associated with the binary object;
returning a response to the remote transfer client, the response comprising the object ID; and
storing the binary object in a binary storage; and
a destination method operated in response to receiving a destination method call from the transfer client, the destination method call comprising the session ID, the object ID, and the MQPUT parameter, the destination ID method comprises executing the MQ Put processing call to the transfer server message queuing manager, the processing call delivering the binary object associated with the object ID from the binary storage to the transfer server method queuing manager in conjunction with the destination queue definition.
2. A method of operating a system for secure automated transfer of a binary object between a transfer client message queuing manager and a transfer server message queuing manager over the Internet, the transfer client message queuing manager operating in conjunction with a remote file transfer client the method comprising:
storing file transfer parameters in association with identification of the remote file transfer client, by;
storing, in an event key table, a plurality of records, each record associating an event with identification of the remote transfer client, each event being identified by an event key value stored in an event key field; and
storing, in an event parameter table, a plurality of records, each record associating a event parameter with the event key value, the event parameters comprising upload even parameters, the upload event parameters comprising:
an MQ get parameter comprising data necessary for the transfer client to initiate an MQGET processing call to the transfer client message gueuing mangers and obtain a message in a queue identified in the processing call;
an MQ Put parameter comprising all data necessary for the system to initiate the MQ Put processing call to the transfer server including a destination queue definition which provides for queuing of the binary object with in the defined queue of the transfer server for retrieval by a destination application;
in response to a log on method call from the remote transfer client, the log on method call comprising identification of the remote transfer client, executing a log on method, the log on method comprising:
assigning a session ID to a web services session with the remote transfer client, and
returning a response message to the transfer client, the response method comprising a session ID;
in response to receiving a retrieve active event keys method call from the transfer client, the retrieve active event keys method call including the session ID, executed, a retrieve active event keys method, the retrieve active event keys method comprising:
obtaining, the identification of the remote transfer client associated with the session ID included in the method call;
