Java Cloud Service Integration to REST Service By Jani Rautiainen
September 14, 2014 Leave a comment
Service (JCS) provides a platform to develop and deploy business applications in the cloud. In Fusion Applications Cloud deployments customers do not have the option to deploy custom applications developed with JDeveloper to ensure the integrity and supportability of the hosted application service. Instead the custom applications can be deployed to the JCS and integrated to the Fusion Application Cloud instance. 
This series of articles will go through the features of JCS, provide end-to-end examples on how to develop and deploy applications on JCS and how to integrate them with the Fusion Applications instance.
In this article a custom application integrating with REST service will be implemented. We will use REST services provided by Taleo as an example; however the same approach will work with any REST service. In this example the data from the REST service is used to populate a dynamic table.
Pre-requisites
Access to Cloud instance
In order to deploy the application access to a JCS instance is needed, a free trial JCS instance can be obtained from Oracle Cloud site. To register you will need a credit card even if the credit card will not be charged. To register simply click "Try it" and choose the "Java" option. The confirmation email will contain the connection details. See this video for example of the registration.
Once the request is processed you will be assigned 2 service instances; Java and Database. Applications deployed to the JCS must use Oracle Database Cloud Service as their underlying database. So when JCS instance is created a database instance is associated with it using a JDBC data source.
The cloud services can be monitored and managed through the web UI. For details refer to Getting Started with Oracle Cloud.
JDeveloper
JDeveloper contains Cloud specific features related to e.g. connection and deployment. To use these features download the JDeveloper from JDeveloper download site by clicking the "Download JDeveloper 11.1.1.7.1 for ADF deployment on Oracle Cloud" link, this version of JDeveloper will have the JCS integration features that will be used in this article. For versions that do not include the Cloud integration features the Oracle Java Cloud Service SDK or the JCS Java Console can be used for deployment.
For details on installing and configuring the JDeveloper refer to the installation guide
For details on SDK refer to Using the Command-Line Interface to Monitor Oracle Java Cloud Service and Using the Command-Line Interface to Manage Oracle Java Cloud Service.

As cloud computing becomes an essential aspect of business operations for many companies, there is a pressing need to integrate cloud applications with on-premises applications. According to a recent study, however, companies frequently have significant cloud integration challenges, with 53 percent of respondents saying lack of integration with cloud applications is their main hindrance to innovation.1 The middleware solutions in the Oracle AppAdvantage program eliminate this hindrance by sharing standards and components among all enterprise applications. This high level of consistency between Oracle Applications and Oracle integration solutions are key enablers for innovation and competitive advantage.
