The CICS Explorer Software Development Kit (SDK) provides an environment for developing and deploying Java applications in CICS, including support for OSGi.
You can use the SDK to create new applications or repackage existing Java applications to comply with the OSGi specification. The OSGi Service Platform provides a mechanism for developing applications using a component model and deploying those applications into a framework as OSGi bundles. An OSGi bundle is the unit of deployment for an application and contains version control information, dependencies, and application code. The main benefit of OSGi is that you can create applications from reusable components that are accessed only through well-defined interfaces called OSGi services. You can also manage the life cycle and dependencies of Java applications in a granular way. For information about developing applications with OSGi, see the OSGi Alliance website.
You can use the SDK to develop a Java application to run in any supported release of CICS. Different releases of CICS support different versions of Java, and the JCICS API has also been extended in later releases to support additional features of CICS. To avoid using the wrong classes, the SDK provides a feature to set up a target platform. You can define which release of CICS you are developing for and the SDK automatically hides the Java classes that you cannot use.
See the CICS Java Developer Guide in the SDK help for full details on how you can perform each of the following steps to develop and deploy applications.
