Get Started with Oracle 12c - Hello World Example

Prerequisites:

• Install Oracle SOA 12c
• Configure default domain and start the server

Let’s get started with the example. First create a new SOA application,If you are not able to see SOA Application then first you need to install Extension SDK in Jdeveloper

Name your SOA application and BPEL process. We choose standard composite as we are not creating this composite from any template.

Once you create the composite, Drag BPEL process to it.

Add synchronous BPEL to the empty composite.

Add assign activity which simple assign request to response.

Now deploy your composite to integrated server.

Once you deploy it go to Application Servers and go to IntegratedWebLogicServer -> SOA -> Default Server -> {Partiiton_Name} -> {Composite}

Right click on the composite to test it. You may face below error when you try to test it.

Error: Error occurred while opening service WSFL URL

To avoid this error we need to disable SSL listen port for server. To do that goes to admin console (http://host:port/console)

Click on Home -> Servers ->Deafultserver -> Configuration ->General

Un-check “SSL Listen Port Enable” and restart the server.

Now test again your composite.

You see it will open HTTP Analyzer and we can test the composite from here only. We need not to open EM console and test it from there.

Provide input value and you see response.

Oracle SOA 12c Features

Oracle has released SOA Suite 12c and lots of new features are introduced in this release. Below is list of some of the new features.

Single Installer: Oracle Suite 12c comes as single installer for developers that means you only need to install only one setup (SOA Suite 12c), DB/Weblogic/SOA will get installed, you need to install it separately. Oracle SOA 12c use Java Derby database, which is file based and that makes it really fast.

Single IDE: In Oracle SOA 12c Jdeveloper is used as IDE for all designs. For OSB development we need not to use different IDE (Eclipse) anymore, we can develop OSB application in Jdeveloper itself.

Debugger: This is new feature in Oracle SOA 12c, debugger is introduced to debug SOA and OSB applications. With the help of debugger we can debug our code before deploying it; this saves lot of development efforts. We can also change message text while debugging it.

Graphical MDS: In Oracle SOA 12c graphical tool is provided to publish, search and consume filed from MDS and OER.

SOA Templates: With the introduction of templates sharing of code between teams become earlier and development efforts reduced. There are three types of templates introduced.

• Project Template
• Component Template
• Custom Activity Template

BPEL Sub-process: Sub-process is introduced in this launch which helps to reduce redundancy. Suppose we need to update database table 3 times in one flow so instead of add 3 different invoke to same BPEL, create sub-process which update the database table and use that sub-process 3 times in that BPEL. There are two types of sub-processes.

• Standalone sub-process
• Inline sub-process

Re-sequencing in OSB: In 11g this feature was available in Mediator, in Oracle SOA 12c this features added to service bus also, with the help of this feature we able to process the request message in proper sequence.

Adapter: Coherence, LDAP and cloud adapter are introduced in this release.

Xquery Mapper: In this release Xquery mapper is introduced which provide XQuery support.

Enterprise Service Scheduler: ESS is out of box scheduler. By using this we can schedule the services.

Translate Activity: Translate activity is also introduced which is used for Native to XML and XML to Native transformation.

MDS support for OSB: In 11g version MDS support was not there for OSB but in 12c MDS support is provided for OSB.
