WTX Overview
Agenda
•
Goal today is to provide the very basics
•
The fundamentals course for WTX is a 5 day class
•
Overview
•
WTX Tools, Components, Development Environment.
•
Demo building a WTX interface start to finish.
What is WTX?
IBM WebSphere Transformation Extender
WTX is…
•
A fully mature tool

It’s been around since 1992.

IBM bought in 2006 and version 8.2 was the first in Eclipse.
•
An any-to-any mapper
•
Multiple inputs and outputs in any format

•
Adapters:

•
Flat files, XML, Database, X12, SWIFT
File, Database, MQ, HTTP, FTP, SOAP, Shell/Batch
Very good at:

Parsing and validating flat files

Complex transformations
What Sets WTX Apart? It’s Fast.
• Very Fast Development
•
Full library available on your desktop for fast and easy testing
•
No deployment to a server necessary to unit test code
• Very Fast Runtime Execution
•
Compiled C
•
Parse and validate 500 meg flat files
in 20-30 seconds
WTX Components
Type Tree Designer
•
Trees are similar to XML schemas
•
They represent the structure of the input and output data
•
Just like XML you have simple and complex objects to build representations of
your data

Simple Objects are called Items

Complex Objects are called Groups
Map Designer
•
Defines Transformations and Business Rules
Other Tools

Database Interface Designer

Importers

Resource Registry
WTX Development Methodology
WTX in Four Steps
1. Develop Trees
•
Create or import Input Trees to parse and validate data
•
Create or import Output Trees to build your output structure
2. Develop Maps
•
Functional Maps (Looping), Drag and Drop Groups and Items
•
Unit test locally on your desktop
3. Deploy to Runtime
•
Deploy compiled maps to be executed by WESB
4. Troubleshooting
•
Trace, Audit logs, Debugger, Profiler
DEMO
WTX Importers
Importing Trees
•
Provides automated creation of
Type Trees saving you hours of
development work
•
Formats Include:
 XSD (XML)
 Fixed length Flat Files (copybook)
 WSDL
 Type Tree Maker (advanced)

WTX Perspective
• Design Studio
•
Has it’s own version of Eclipse
• WebSphere Integration Developer
•
We can use this version of Eclipse to develop WESB flows and
open maps/trees using the WTX perspective
WTX at Runtime Execution
WTX Runtime Mapping Steps
1. Read all input cards sequentially into memory

Read Input card 1, 2, 3, etc.

All Inputs are available for use in any output
2. Executes output cards sequentially

Output card 1 completes, 2 completes, etc.

Output card 3 card may use data from output card 1 & 2
