New OSB project in SOA 12C by using JDeveloper

Maha Technology is a leading Oracle SOA Suite 11g and BPEL 12c, Oracle Service Bus 11g and 12c training and consulting company from Hyderabad by a group of highly experienced professionals from Oracle and having more than 10+ years of real time project and training experience. We also provide the training for other Fusion Middleware technologies like Oracle BPM 11g, Oracle ADF, Oracle IDM and SAP ( All modules) technologies.

From Oracle SOA 12c Jdeveloper is the single GUI which can be used tio build both SOA and OSB projects. If you have already worked in OSB you will not find it much difficult as the look and fields are very much similar in Jdeveloper, There are lot of changes also but you should not be facing many issues to start up. In this exercise we will try to create a simple Service in OSB.It will have following things.

A Schema for the output format. A business Service to write file to a directory and a proxy service which will accept input from the user.So if the idea is clear we will go ahead and create a new OSB project.

Open your Jdeveloper and create a new Service Bus Application



Let the default application name be there



Now within the application Create a new service bus project



Let the default project name be there and finish the project



Now once project is created, right click on the project and create a new Schema document

<?xml version="1.0" encoding="UTF-8"?>
<schema attributeFormDefault="unqualified"
elementFormDefault="qualified"
targetNamespace="http://xmlns.oracle.com/testing/ArpitSchema"
xmlns="http://www.w3.org/2001/XMLSchema">
<element name="process">
<complexType>
<sequence>
<element name="input" type="string"/>
</sequence>
</complexType>
</element>
<element name="processResponse">
<complexType>
<sequence>
<element name="result" type="string"/>
</sequence>
</complexType>
</element>
</schema>


Now Drag and drop a File technology adapter in the External Service Swimlane






Let the default jndi be there



Select write operation



Select path and file name



Select the process type in the schema



Complete and finish the wizard



Now once project is finished you will find following artifacts in the project.



YOu can see a .bix file which is nothing but the business service. Just right click on the Business service and say run.
This will give you an option to test the Business service that you have created just now.

HTTP analyzer will open up in JDveloper itself and you will be able to test it.



Test and validate whether the file is create at back end or not.

Now we will further enhance this project and add a proxy service to it.

Drag and drop a pipeline activity in the pipeline swimmlane



Create a messaging service and select the input and output from the schema



Finish the project and link your osb project with the file adapter.



NOw double click on the proxy service and drop a publish activity in the request pipeline




Publish activity is used to call a service in one way.

After putting the publish activity point it to the business service you have created earlier and save the changes.



Since the body and the file adapter input is based on same schema there is no mapping required just click on the proxy service and say run.



Validate the output



Now if you wanted to test your same service from em console just log in to em console

http://host:port/em

Click on your project and then go to operations tab as shown

Once you reach in the operations tab click on your proxy service



Click on the test tab



And test it from the console
