1 Introducing Oracle Java Cloud Service

Oracle Java Cloud Service provides a platform to develop and deploy business applications in the cloud. With Oracle Java Cloud Service (Java Cloud Service), businesses can maximize productivity with instant access to a cloud environment powered by Oracle WebLogic Server, complete with integrated security and database access. This section provides a brief introduction to Java Cloud Service. It explains core Java Cloud Service concepts and how to install the Java Cloud Service SDK, and offers an overview of deploying Java EE applications.

About Oracle Java Cloud Service

Oracle Java Cloud Service reduces the complexity associated with the deployment and maintenance of enterprise Java applications. It enables you to create Java Cloud Service instances quickly. You can deploy your applications to a service instance, then secure and manage them without worrying about the underlying infrastructure.

Using the Java Cloud Service you can instantly create Java EE environments within the Oracle Cloud. These applications can be deployed in standard WAR (Web Application Archive) or EAR (Enterprise Archive) formats. Beyond the standard Java EE specifications, Java Cloud Service also supports the deployment of applications that make use of Oracle WebLogic Server-specific extensions as well as Oracle Application Development Framework (ADF) constructs.

Understanding Key Java Cloud Service Concepts

The following graphic illustrates the core architecture of Java Cloud Service and its relationship with Oracle Cloud.

As shown in the previous illustration, Java Cloud Service instances are hosted within the Oracle Cloud in a data center operated by Oracle. This architecture provides a great deal of power and flexibility. Advantages include:

Once you create an Java Cloud Service instance, administrators can access the service in the following ways:

Additionally, the Java Cloud Service provides tooling within the Oracle JDeveloper, Oracle Enterprise Platform for Eclipse, and NetBeans IDEs that enables developers to directly interact with target service instances as part of the development process. To learn more, see "Using Integrated Development Environments".

About Installing the Java Cloud Service SDK

The Java Cloud Service SDK (software development kit) provides utilities that facilitate the management of Java Cloud Service instances and the development of applications for the Java Cloud Service. The Java Cloud Service SDK is a downloadable package that contains the following components, in addition to some examples and documents:

To download the Oracle Java Cloud Service SDK:

  1. Go to the Oracle Cloud home page (http://cloud.oracle.com), or to any Oracle Cloud page that has the Resources menu.

  2. From the Resources menu, select Downloads.

    The Downloads for Oracle Cloud Services page appears.

  3. If prompted, sign in using your Oracle.com account credentials.

    All relevant downloads will be accessible on the page. Downloading software will require you to accept the license agreement.

  4. Find Oracle Java Cloud Service SDK and download it.

About Deploying Java EE Applications

You can deploy Java EE applications, including Enterprise Archive (EAR) and Web Application Archive (WAR) files to a Java Cloud Service using:

To learn more, see "Developing Applications for Oracle Java Cloud Service".

Accessing Deployed Applications Using a URL

Once you deploy an application to a Java Cloud Service instance, users can access it using a web browser. All applications deployed to a Java Cloud Service can be accessed using the following URL:

https://<servicename-identitydomain>.java.<dc>.oraclecloudapps.com/<appname>

Where:

  • <servicename-identitydomain> is the name of the Java Cloud Service instance chosen at creation time , a hyphen, and the name of the Java Cloud Service instance identity domain.

  • <dc> is the short name of the data center. For example, us1 refers to the US Commercial 1 data center.

  • <appname> is the name of the target application. Typically, appname is the application context root.
