My Extra uses smart connectors, which are intelligent APIs, allowing the applications to be accessed as a Web service without the need to change the legacy code. This means that undocumented but reliable applications can be left unaltered.
The package uses a drag-and-drop screen to create the connectors. The developer selects the input and output variables and draws them over to create an Enterprise Java Bean. This object can be used as a Web service to create new applications, user interfaces or used in messaging systems such as Microsoft MSMQ. It also makes it possible to map the output to XML-based services.
Michael Jensen, area director for Attachmate, said, The IT department can put the mainframe back in the glasshouse without excluding the resources it contains from the Web services world."
My Extra is available for IBM mainframes, zSeries and iSeries. The company is planning products for HP Tandem and for Unix systems.
