Both Oracle SOA Suite and Oracle Unified Business Process Management Suite make it possible to embed Java code as a Service Component Architecture (SCA) first-class citizen through the Spring component implementation type. Thereby the coarse-grained components of Oracle SOA Suite are extended by the much-finer-grained Spring beans wrapped inside the Spring component. This session presents five cool use cases for the Spring component. It shows how and why you would want to use the Spring component and will hopefully inspire attendees to use it for their own projects.

6. Spring Service Component
The Spring Framework is a lightweight container using “plain old Java
objects” (POJOs)
WebLogic SCA enables the usage of the Spring Framework and to expose
components as SCA services and references
SCA extends Spring framework capabilities
• Publish spring beans as SCA component services
• Provide references to Spring beans wired to services of other components
Following types of component integrations are supported
• Java components to WSDL components
• WSDL components to Java components
• Java components to Java components

9. <sca:service> Element
Declares a Spring bean that SCA exposes as a service
Takes the following attributes:
• Name
 the name of the service (required)
• Type
 The fully qualified Java type of the Java class to be exposed as an SCA service
(required)
• Target
 The bean to be exposed as a service (required)

10. <sca:reference> Element
Declares a Spring bean representing an SCA service external to the Spring
application context
Takes the following attributes:
• Name
 The name of the reference (required)
• Type
 The fully-qualified Java type of the interface or class representing the remote service
(required)
• Default
 The target bean for the reference if none is specified (optional)

11. Using the Predefined Beans
The following spring beans are predefined in SOA Suite:
• headerHelperBean – for getting an setting header properties
• instanceHelperBean – for getting Instance ID of composite and component,
name of the Spring service component
• loggerBean – for providing context-aware logging message
You can also define your own Spring beans globally => see use case 3

13. Case 1 – Configuration: Within SOA Suite
Use Case: Need configuration properties which are changeable at runtime
With SOA Suite preferences can be added to the SCA composite
• Has to start with bpel.preference
Use ora:getPreference('greetingMessage')from within BPEL
Restriction: Only scalar values are supported!

25. Case 3 – NoSQL: What is NoSQL?
NoSQL is a new class of databases
Common characteristics of NoSQL databases
• They don„t use the relational data model and thus don„t use SQL
• Tend to be designed to run on cluster
• Tend to be Open Source
• Schema-Less - Don„t have a fixed
schema, allowing to store any RDBMS NoSQL
data in any record Presentation
Tier
User Interface User Interface
• Different APIs Key Value Stores
Services
Caching Search
Middle Tier Object-Relational Relational-Object Lucene
Transactions Batch
MapReduce
Search Blobs
Database Tier Transactions Batch Data
Caching Triggers

31. Case 3a – NoSQL: MongoDB Logging Bean
Define bean in the global spring context (custom predefined bean) so that
logging is globally available
1. Add the bean definition here
 SOA_HOME/soa/modules/oracle.soa.ext_11.1.1/classes/
springse-extension-global-beans.xml
2. Add the corresponding classes in either the lib or classes directory
3. Run the ant script and restart server (more information in
readme.txt)

42. Summary
The Spring component is a nice way to extend the functionality of the SOA
Suite and the other service engines
Use cases for it are endless ….
Only use the Spring component if no out-of-the-box feature in the SOA
Suite exists
Make sure that you test the Java and Spring stuff externally first
Only Spring Framework 2.5 …
