OSGi Blabber sample

The OSGi applications programming model helps you develop and deploy modular applications that use both Java EE and OSGi technologies. You can design and build applications and suites of applications from coherent, multiversion, reusable OSGi modules that are accessed only through well defined interfaces. This reduces complexity, and provides the greatest flexibility to maintain and evolve an application after its first release.

Prerequisites for use

  • WebSphere® Application Server Version 8.0 or Version 8.5
Important: These samples were tested with WebSphere Application Server Version 8.0 and Version 8.5.

Sample download

To use the sample, download OSGi blabber files from a product download site:

  1. Choose one of the following methods to download the blabberSample.zip file to a directory on your workstation: FTP or HTTP. You might create the /samples/blabber directory path on your workstation and download OSGi Blabber sample files to that directory path.
  2. From the displayed dialog, specify the target directory to which to save the compressed file and click OK.
    The blabberSample.zip file contains sample files in the following directory structure:
    /com.ibm.samples.websphere.osgi.blabber
    /com.ibm.samples.websphere.osgi.blabber.persistence
    /com.ibm.samples.websphere.osgi.logging.api

Sample description

Blabber sample application
The blabber sample application is a microblogging application for enabling many different people to share brief comments. This application shows how to write and package bundles into an enterprise bundle archive (EBA) file.
The sample application consists of two bundles, divided into the following functional areas:
  • com.ibm.samples.websphere.osgi.blabber.persistence, which contains code relating to the Java Persistence API (JPA) layer, and also contains the interface that is used by the main application code.
  • com.ibm.samples.websphere.osgi.blabber, which contains the main application logic code, and interacts between the web front end and the back end persistence code layer.

You can use scripts to perform a complete install, or use scripts to perform just the initial configuration of the application then use the administrative console to install the application into the application server. You can also use, modify and remove the sample.
