Spring SCA Component

Spring is a lightweight container using “plain old Java objects” (POJOs)

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

<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)


2013 © Trivadis

<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)


2013 © Trivadis

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

Agenda

1.  Introduction


3.  The use cases §  Case 1 - Configuration

4.  Summary


2013 © Trivadis

Case 1 – Configuration: Within SOA Suite

Use Case: Need configuration properties which are changeable at runtime

Within a SCA Composite preferences can be declared

•  Has to start with bpel.preference

Use ora:getPreference('greetingMessage')from within BPEL

Restriction: Only scalar values are supported! Can only be accessed from a BPEL component.


2013 © Trivadis

Case 1 – Configuration: Within SOA Suite

Values can be changed through System MBean Browser in EM §  oracle.soa.config > Server : soa_server1 > SCAComposite > your_project >

SCAComposite.SCAComponent > your bpel_process

3.  The use cases §  Case 4 – NoSQL

4.  Summary


2013 © Trivadis

Case 4 – NoSQL: What is NoSQL?

NoSQL is a new class of databases

They don‘t use the relational data model and thus don‘t use SQL

Tend to be designed to run on cluster

Schema-Less - Don‘t have a fixed schema, allowing to store any data in any record

Different types of NoSQL databases

•  Key/value

•  Column Family

•  Document

•  Graph

Case 4a – NoSQL: MongoDB Logging Bean


2013 © Trivadis


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)

Case 6: so many more ideas …. And not enough time

•  Invoking Spring Batch

•  Invoking Hadoop Processing

•  Groovy Script integration (i.e. XML ó JSON)

•  Read/Write Excel

•  Create PDF

•  Submit to Evernote

•  Message Enrichment (Mediator cannot do that)

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!

Bring your Java people „on board“ …..

Make sure to first test the Java and Spring stuff externally!
