Q

The life cycle of WebFacing applications

I have installed IBM's WebSphere Development Studio Client for iSeries. Now I have to convert DDS files to JSP, Java files. If I change the DDS display file source member after I WebFace an application, will this change reflect on the other side?
You seem to understand the "life cycle" of WebFacing applications clearly. If you change the DDS display file source member AFTER you've WebFaced an application, you need to:

1. Reconvert only that specific DDS source file in your WebFacing application.

2. Export your WebFacing application to a .war file again.

3. Redeploy the .war file to your application server.

The communication between the WebFacing Java code and the host 5250 RPG application is based on the DATA BUFFERS for input and output for each record format. Any changes to the buffers in your DDS display file or their contents require you to reconvert that specific display file.
