Creating Oracle Database-backed iGoogle Gadgets

Learn how to build gadgets for iGoogle and OpenSocial containers that read data from an Oracle database.

Gadgets within personalized home pages are an interesting channel to distribute information and extend the reach of Web applications. As we work more and more on "extended enterprise" or enterprise 2.0 applications, enterprise developers are looking for new ways to reach our users, and to integrate within the flow of information that the user is otherwise receiving.

In this article you'll learn how to use an Oracle database (with its native support for HTTP and XML) as a backend for a Google gadget. We'll do this while building a few simple gadgets that pull data from the database, and using Oracle XML DB to host associated static files. No prior knowledge of the Google gadgets specification is needed and all of the examples have been tested on Oracle Database XE (and will probably run on Oracle Database 11g as well).

    What is coLinux
    coLinux logo


    Cooperative Linux is the first working free and open source method for optimally running Linux on Microsoft Windows natively. More generally, Cooperative Linux (short-named coLinux) is a port of the Linux kernel that allows it to run cooperatively alongside another operating system on a single machine. For instance, it allows one to freely run Linux on Windows 2000/XP, without using a commercial PC virtualization software such as VMware, in a way which is much more optimal than using any general purpose PC virtualization software. In its current condition, it allows us to run the KNOPPIX Japanese Edition on Windows (see Screenshots).

    milton:
    an open-source server-side webdav api for java

    Milton is an open-source server-side webdav API written in java.

    You use Milton to expose the data in your web application via webdav. This data could be from a relational database, the file system, or any other data source. Milton makes no assumptions about the nature of your data.

    Its been tested and works well with Windows XP, Linux and MacOS. Note that webdav support in Windows Vista has issues and users might need to download a patch. The two main office applications, Open Office and MS Office, also have build in webdav support and both have been tested and work well with Milton.
