Title: SPAGIC

1
SPAGIC
The complete Free/Open Source SOA BPM Solution

By
Nawaz Khurshid
LEGO- Lab(SOA Group) Fondazione Bruno Kessler

2
Objective

. Integrate process in Enterprise Service Bus.
. Implement the Integration architecture that
support the routing,
mediation and translation of these three basic
layers.

3
SOA Reference Model

Key points
SOA/BPM Governance
Full Open Source Model
Product Independent

Capabilities
Efficiency of involved actors
Reduce the gap between business analyst and
technology specialist
Business Process Monitoring and Management

4

6
Standard

BPMN Business Process Modeling Notation ( BPMN
)
STP IM Eclipse STP Intermediate Model
ESB
JBI Java Business Integration
BPEL

7
BPMN

Graphic Notation to design business processes
Defined by OMG ( February 2006 )
Actually there is no a standard for
representing BPMN by XML
It does not provide technological statements
It must be enriched to be executed
http//www.bpmn.org/

8
BPMN- Pool Lanes

Pool Container of orchestration processes
Lane Partitioning of a pool that represents
a role, or a boundary of an organization unit

9
BPMN- Events
10
BPMN- Activities
11
BPMN- Flow Elements
12
BPMN- Gateway
13
BPMN- Artifact
14
STP- Intermediate model

Eclipse Official Project
Made collaborating with Eclipse
Goals
Define a generic model for processes and
services
Separate the design tools and the code
generators
Share the information between the different SOA
technologies
Interoperability between editors
Conceptual transport between different
development spaces.
Capture common SOA design information.
Possible incorporation of new editors.

15
Enterprise Service Bus

There is no standard definition of ESB
Sometimes its used as synonym of SOA
Usually redefined by vendors according to the
needs
Architectural Model with enabling features
Distributed Architecture
Open Standard ( vs. Closed Standard )
Transparent to the protocol
Heavily based on XML and the standards WS-

16
JBI- Java Business Integration

Decouples the applicative services from the
connectivity management
Binding Components (connectivity to external
service)
Service Engine (business logic and
transformation services)
Architectural model based on message exchange
through a router
Normalized Message Router

17
JBI- Binding Components/ Service Engines

Binding Components ( Protocol Adapters )
Responsible of protocol/trasport interactions
Normalize and Denormalize the messages to and
from different protocols formats ( Marshalling
Unmarshalling )
Examples HTTP/SOAP, Directory Poller, JMS
Service Engine
They implement the business logic
They manage as input/output objects only the
Normalized Message
Examples XSLT Transformer, Query JDBC, Script

18
SPAGIC- Binding Components

HTTP/SOAP
CXF-BC (Celtix Xfire)
File
JMS
Quartz Timer
JDBC Poller
TCP/IP
Mail

19
SPAGIC- Service Engines

XSLT Transformer
Syntax Validator ( XSD Validator )
validates payload against XSD schema.
Drools Validator
Rule, when and then construct.
Drool file is provided to drool validator.
Router
construct for modeling gateways.
select destination based on some rules on
message content.
Split Aggregator
Parallel Join

20
Sample Drool File
21
SPAGIC- Service Engines

Scripting
groovy language
JDBC Simple
JDBC Advanced
possibility to run stored procedures

22
Modeling Techniques
23

Demo 1

Syntax and Semantic Validation

24
Process 1
1.Receive a message 2.Perform Syntax
Validation. 3.If validation is OK 3.1. Perform
Semantic Validation 4. If validation is OK 4.1
Transform message. 5.End
25
BPMN
26

Demo 2

Invoking Supplier Web Service

27
Process 2

1.Receive a message
2.Make Script
3.Prepare input for Supplier Call.
4.Call Supplier Web Service
5.End

28
BPMN
29

Demo 3

Order Process
Store Process

30
Order Process

1. Receive input.
2. Check Credit
2.1. Generate Invoice
2.1.1 End
2.2. Notify CRM System
2.2.2 End
2.3. Generate Input for Store Process
2.3.1 End

31
Store Process

Receive Input from Order Process.
Prepare Store Order
Prepare data
3.1. Prepare data for Logistic
3.1.1 Invoke logistic service
3.2. Prepare data for supplier
3.2.1 Invoke supplier service
4. Display the combined output to console.

32
Order- Store Process store Process

Receive Input from Order Process.
Prepare Store Order
Prepare data
3.1. Prepare data for Logistic
3.1.1 Invoke logistic service
3.2. Prepare data for supplier
3.2.1 Invoke supplier service
4. Display the combined output to console.
