User's Guide
The MQSeries Internet Gateway accepts an HTML file from a Web browser and extracts the MQ specific information. This information is then
repackaged into a form that can be interpreted by specially written MQ applications. The MQ application sends the reply back
to the gateway in a special format which the gateway repackages into an HTML file and passes it to the browser for display.
The MQ applications that can interact with the MQSeries Internet Gateway are described as being
'Web-aware'.
Web-aware MQ applications do not use any new or specific MQ calls, but they need to be
written in a particular style.
Data is received from the gateway in a particular format, and the return message to the gateway has a specific format.
Both these formats are included in the sample programs which can be found in
the '\samples' subdirectory of your installation.
- dmqsamp1
- shows how to code a simple two step conversation. Browser form data is received,
formatted, and sent back to the browser in a table.
- dmqsamp2
- demonstrates multiple users having multiple state
conversations with MQ through the MQSeries Internet Gateway.
The session is provided as a series of forms, and all the data
that is entered on the browser is kept in a session control block.
You should be aware that this
sample does not cater for all error conditions. In particular, it does not clean up the
held session information if you close a browser without using the 'exit' button to
terminate a session. These conditions would need to be handled in any user written
multi-session applications applications
