Integrating documentation plug-ins

Documentation that is fully integrated is easier and quicker to search for help topics compared with accessing the information remotely. If you have local documentation that is in one or more plug-ins, you can integrate it fully with the CICS Explorer® Help Contents. You can also integrate documentation from another source; for example, you can include one or more of the CICS®, or any other, Information Center plug-ins.

Creating a plug-in

The CICS Explorer is built on the Eclipse open source platform, which provides an extensible integrated development environment. Using the Eclipse platform, anyone can build tools that integrate seamlessly with the environment and other tools. The key to the seamless integration of tools with Eclipse is the plug-in. With the exception of a small runtime kernel, everything in Eclipse is a plug-in. A plug-in that you develop integrates with Eclipse, and so with the CICS Explorer, in exactly the same way as other plug-ins.

When you create a documentation plug-in, it is fully integrated with the CICS Explorer, and the contents are displayed in the Help Contents.

You can create your own documentation plug-in using the Eclipse Plug-in Development Environment (PDE), which is available in the Eclipse Integrated Development Environment (IDE). The Eclipse IDE is open source and can be downloaded from the Eclipse Web site http://www.eclipse.org. The documentation explains how to get started, and a cheat sheet provides step-by-step instructions for creating a plug-in.

Integrating documentation plug-ins

You havetwo ways to integrate plug-ins in the CICS Explorer depending on how they are packaged:
Using the software update function
If one or more plug-ins are packaged in an Eclipse software update site, you can use the software updates function in the CICS Explorer to access the site and view the contents. You can then download one or more plug-ins to your local copy of CICS Explorer. This method has advantages and disadvantages.
Advantages:
  • If the source plug-in changes, updates an be downloaded automatically.
  • After the download, the plug-in is stored on your local machine and always available.
Disadvantages:
  • Downloading can take a long time depending on the number of plug-ins and their sizes.
  • Internet access might be required for remote software download sites.
Using a link file
If you have access to one or more plug-ins either on your local machine, on a network drive, or on a CD, you can create a file in the CICS Explorer Links directory that points to the plug-ins. The plug-ins are integrated when the CICS Explorer starts and they are displayed in the Help Contents. This method has advantages and disadvantages.
Advantages:
  • Plug-ins can be managed centrally and accessed by multiple users.
  • Different directories can contain different plug-ins. For example, one directory can contain only message plug-ins, and another can contain messages and CICS RDO plug-ins.
  • Multiple link files can be used, each one pointing to a different directory of plug-ins.
Disadvantages:
  • If the plug-in is stored remotely and the network connection is lost, the documentation cannot be displayed in the CICS Explorer.
  • When the network connection to a remote plug-in is restored, the CICS Explorer must be restarted to show the documentation.
