Agenda

• Business Processes and Sonic ESB
• OpenEdge Adapter for Sonic ESB
• Native Invocation Methodology

3
Business Processes

• How do you create business processes that execute
  ABL components?
• With Sonic ESB!
• Flexibly assemble
  components
• Heterogeneous
• Distributed
• Scalable

OpenEdge Adapter for Sonic ESB

• ABL components participate in business processes
  controlled by Sonic ESB
• Prior to OpenEdge 10.1C
• ABL is disguised as Web services
• Developer needs detailed knowledge of Web service
  technologies
• The setup in OpenEdge and Sonic is complex
• Starting with OpenEdge 10.1C
• Native Invocation Methodology Added!

ABL Native Invocation Methodology

• Sonic ESB calls ABL procedures, functions and
  external procedures directly/natively
• AppServer call information is collected at
  development time
• Source code annotation preferred
• AppServer run-time properties service
  initialization info stored in invocation files
• Input/output parameters of ABL procedure mapped
  to Sonic message content
• Sonic ESB Process Editor

Supported AppServer Session Models

• Session-free (recommended)
• No session between client AppServer is
  maintained
• AppServer runs in a state-free operating mode
• Session-managed
• Client to AppServer persistent connection
  maintained
• AppServer runs in State-reset, State-aware or
  Stateless operation modes

10
Unified Development Environment

• OpenEdge Architect and Sonic Workbench are both
  based on Eclipse
• Easy to configure a combined development
  environment in a single Eclipse instance
• OpenEdge 10.1C and either Sonic 7.5 or 7.6
• No switching between OpenEdge and Sonic
• Single unified view of project resources

Native Invocation Development Process
New in OpenEdge 10.1C
STEP 1 Create .esboe file for each ABL procedure STEP 1 Create .esboe file for each ABL procedure STEP 1 Create .esboe file for each ABL procedure
Annotate Source Code Annotate Source Code Dont Annotate ProxyGen builds .esboe from r-code
OE Architect Annotation Wizard .esboe built on-compile or on-demand Manually Command line utility to build .esboe Dont Annotate ProxyGen builds .esboe from r-code
STEP 1 Create .esboe file for ABL procedure
OE Architect Annotation Wizard .esboe built on-compile or on-demand
STEP 2 .esboe file in Sonic project (automatic or import)
STEP 3 Drop .esboe onto Sonic Workbench Process Editor
STEP 4 Map ABL parameters to message parts
OpenEdge Architect must be installed
13
Code Annotation Example
_at_openapi.openedge.export(typeESB,ESBOEFilename
PROCNAME)
DEFINE INPUT PARAMETER ItemNumIn AS INTEGER
NO-UNDO. DEFINE OUTPUT PARAMETER DATASET FOR
dsItemLocations. FIND Sports2000.Item WHERE
Sports2000.Item.Itemnum ItemNumIn. IF
AVAILABLE(Item) THEN DO CREATE ttItem.
ASSIGN ttItem.Itemnum Sports2000.Item.Itemnu
m ttItem.ItemName Sports2000.Item.ItemName.
FOR EACH Sports2000.Bin WHERE
Sports2000.Bin.Itemnum ItemNumIn
14
Supplying Invocation Information to Sonic
Yes (Declarative)
Add Annotations
Compile Source Code
Add ABL Call to Itinerary in Sonic Workbench

STEP 4 Map ABL parameters to message parts
Graphical mapping available Use XPath to extract/insert simple types Use message parts for TempTables/DataSets
STEP 2 .esboe files in Sonic project (automatic or import)
STEP 3 Drop .esboe onto Sonic Workbench Process Editor
STEP 4 Map ABL parameters to message parts
OpenEdge Architect must be installed

Debugging and Deployment

• Use scenarios in Sonic Workbench Process Editor
  to debug the business process
• Deploy the business process, .esboe file and
  r-code
• ABL is automatically executed when the business
  process runs

Native Invocation Methodology Benefits

• Unified OpenEdge and Sonic development
  environment
• Easy to expose ABL code as a service
• Minimal technical knowledge needed
• Basic use case is automated
• Faster development
• Optimized run-time performance (no SOAP)
