IBM WebFacing and HATS Tools
What is WebFacing?
▪ A Re-Facing tool and runtime for iSeries 5250 applications
▪ Development-time conversion
– Of 5250 display file DDS source into Web page source (JavaServer Pages
or JSPs)
▪ Run-time intercept
– Of workstation data manager I/O to pass application data to generated Web
application, prior to creation of 5250 data stream
– Enables existing applications to run without change, indeed without even
knowing they have been WebFaced

WebFacing Scenario
1. Create new WebFacing project
–
Specify members to convert, look-and-feel style, how to call/invoke the
application
2. Convert the project
–
Creates Web stuff from the DDS and UIM source
3. Run it!
–
Select “Run on Server” to run in built-in WebSphere
4. Refine it
–
Using Web Settings in CODE Designer (launched from WebFacing)
–
Using project’s Properties dialog
5. Repeat
6. Export as EAR file, import into WebSphere Application Server on
iSeries
–
IBM
Or use built-in server-tools support to publish to WebSphere Application Server
on iSeries

Conversion
▪ Creates Java Server Page and XML descriptions per record format:
– XML describes data,view,and feedback for record format
– JSP displays output and prompts for input
▪ Creates an "invocation page" per conversion project: (index.jsp)
– Web page with links
– Each link results in starting a job, running a user-supplied CL command which starts the
application

3 Ways to Customize WebFaced Applications
1. By Properties
–
Much can be affected in the conversion and runtime, including overall style, by use
of properties and style wizard
2. By Web Settings
–
These are DDS comments for affecting the conversion results. Easy to set with the
CODE Designer tool
3. By Editing the Output
IBM
–
Because of the built-in Java and JSP editors, you can always edit what WebFacing
generates
–
But be careful….

Deploying to Remote WebSphere
▪ Use File->Export to export EAR file
– Export to a mapped IFS drive
– Use WebSphere Administrator Console to import EAR file
– Bring up Browser, enter URL to start application
▪ Or, configure a server in Server Tools for iSeries WebSphere
Application Server and use Publish to push to it, and then Run On
Server to run it
▪ Tip: look at Change Management tools like SoftLanding’s to automate
delta deployments
