1 ADF EMG XML Data Control Powerful and Easy ADF Data Control for XML data

2 About Us Richard Olrichs MN Wilfred van der Deijl The Future Group

3 Agenda Short introduction Brief history Alternatives Live product demo Theoretical summary of the demo

4 Short Introduction Goal: An easy way to handle XML in ADF Any XML element can be runtime data XML payload in SOA/BPM Human Task SOAP Web Service response RESTful XML API XML column in database Static file and more

5 Short Introduction ADF abstraction through Data Controls

6 Short Introduction XML Schema is the key XML DataControl gets its structure from XSD Runtime XML document can come from anywhere Human task payload, Static resource, Web service, or wherever you like

7 XML DataControl History Development started at MN in August 2012 Adopted by Spir-it since March 2014 Open to the public ADF EMG sub project Available through Help > Check For Updates

8 Alternatives Calling WebService from ADF 1. ADF WebService DataControl 2. JAX-WS Proxy with Bean DataControl 3. Programmatic Business Components

9 ADF WebService DataControl Alternatives Not customizable, for simple web services Dates and enumerations not supported Only for simple web services like stock info or weather info

10 JAX-WS Proxy with Bean DC Alternatives Lots of work: Generate JAX-WS Proxy classes Domain POJO s Mapper classes (and back). Labor intensive when services change JAX-WS Proxy cannot be used directly as bean DataControl Dates and enumerations not supported JAXBElement getters/setters not supported

11 Programmatic ADF BC Alternatives Lot of work: JAX-WS Proxy ViewObjects EntityObjects Mappers (and back) BC is very database (SQL) centric Commit, Rollback, Fault-In selects, locking, connection pooling, etcetera Requires extensive coding in ADF BC base classes

14 Powerful Providers Data Provider - Fetch XML Element Customization - Supplies customization classes Type Mapper - Map XML to Java types Structure Provider - Builds DC structure from XSD

15 DataProvider Nesting Plain DataProviders WSDataProvider - Web Service ELDataProvider - Expression Language ResourceDataProvider - XML file from classpath Nesting DataProviders Can manipulate dynamic parameters going into the nested dataprovider Get XML from nested provider and can manipulate it before returning it to the caller
