Systems and methods for messaging in a multi-frame Web application

A computer program product embodied in a machine-readable storage medium for handling messages in a Web application, the program product comprising programming instructions for performing the steps of:

• inserting a message handler in a top level document of the Web application;
• inserting a writeable block in a window in a first page of the Web application, the writeable block for receiving a message generated by the Web application;
• and
• inserting a message script in a second page of the Web application, if a message is generated by the Web application for display in response to an execution of the second page, wherein the message handler is invoked in response to the message script.

A data processing system for handling messages in a Web application comprising:

• circuitry operable for inserting a message handler in a top level document of the Web application;
• circuitry operable for inserting a writeable block in a window in a first page of the Web application, the writeable block for receiving a message generated by the Web application;
• and
• circuitry operable for inserting a message script in a second page of the Web application, if a message is generated by the Web application for display in response to an execution of the second page, wherein the message handler is invoked in response to the message script.

A method of handling messages in a Web application comprising:

• inserting a message handler in a top level document of the Web application;
• inserting a writeable block in a window in a first page of the Web application, the writeable block for receiving a message generated by the Web application;
• and
• inserting a message script in a second page of the Web application, if a message is generated by the Web application for display in response to an execution of the second page, wherein the message handler is invoked in response to the message script, wherein the message handler targets a preselected window in the second page of the Web application, the message handler being operable for writing a message string representing the message generated by the Web application in the writeable block, and wherein the writeable block is contained in the preselected window in the second page of the Web application.
