WebFacing Before and After



Table of contents



▪ HATS



▪ Summary



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



Goals of WebFacing

▪ Quick conversionUsing existing skills

▪ Unlimited refinementUsing existing SDA skills, or using Web skills

▪ Cost effectiveTool part of ubiquitous tool set Runtime part of operating systemOnly pre-req is WebSphere Application Server Express or higher

▪ Summary



WebFacing Scenario

1. Create new WebFacing project– Specify members to convert, look-and-feel style, how to call/invoke the

application2. Convert the project

– Creates Web stuff from the DDS and UIM source3. Run it!

– Select “Run on Server” to run in built-in WebSphere4. Refine it

– Using Web Settings in CODE Designer (launched from WebFacing)– Using project’s Properties dialog

5. Repeat6. Export as EAR file, import into WebSphere Application Server on

iSeries– Or use built-in server-tools support to publish to WebSphere Application Server

on iSeries



Create a New WebFacing Project1a

Use File->New->Other



Tip: create new EAR file per project



Select DSPF and MNUDDS members to convert

Advanced option only

Enable Single Sign on support

System screen support now supported by default



Select DSPF and MNUDDS members to convert



Select UIM panel groups (help) to convert



Specify how to invoke application

Specify how to signon

Can specify multiple invocation commands- Each becomes a button in index.html



Selected style is previewed here

Select a style for the look and feel



That’s it! Press Finish to create project



Right-click and select Convert to do conversion

Usually 1 – 5 minutes per member

Can also selectively

convert individual

display files



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



Conversion gives detailed log of all keywords encountered

Not all keywords supported yet…. Log tells you if there’s a problem

See product help for list of unsupported keywordsRun WebFacing Survey tool to check your DDS



Run On Server runs Web app in built-in WebSphere Test Environment

Time to run it!

Starts index.jsp

Assumption: you will replace index.jsp with your own Web page for invoking the app(s)

– you can define your own

FKeys become buttons or links,

▪ Summary



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– Because of the built-in Java and JSP editors, you can always edit what WebFacing

generates– But be careful….



1. Customizing By Properties

These affect conversion

These affect runtime

These affect style



Example of properties

you can change



Styles

You can also significantly change the

look and feel of the whole

by editing the .css and .jspfiles of the

style

Tip: Use Save As

from style’s popup menu



2. Customizing By Web Settings CODE Designer =

1. Select field

2. Customizing By Web Settings V6.0 In workbench

3. Customizing By Editing Output

Use built-in or external editors to

edit output of

conversion



3. Customizing By Editing OutputWhat happens on subsequent

conversion?

The file is replaced with

new file!

Either replace or manually

merge

However, the edited version is

Summary

▪ Summary



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
