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 8.5
Important: These samples were tested with WebSphere Application Server
Version 8.5.
Sample download
To use the sample, download
OSGi colors files from a product download site:
- Choose one of the following methods to download the colorsSample.zip file
to a directory on your workstation: FTP or HTTP. You might create the /samples/colors directory
path on your workstation and download OSGi Colors sample files to
that directory path.
- From the displayed dialog, specify the target directory to which
to save the compressed file and click OK.
The
colorsSample.zip file
contains sample files in the following directory structure:
/com.ibm.samples.websphere.osgi.colors
/com.ibm.samples.websphere.osgi.colors.persistence
/com.ibm.samples.websphere.osgi.logging.api
/com.ibm.samples.websphere.osgi.logging.impl

Attention: The readme.html file
contains information for installing and running the sample.
Sample description
- Colors sample application
- The colors sample application demonstrates two of the key dynamic
abilities of OSGi Applications for WebSphere Application
Server: how to administratively update deployed applications in a
modular fashion, at the bundle level, and how to extend running applications,
as your business requirements change, without changing the underlying
application.
- The sample application consists of the following components, divided
into the following functional areas:
- com.ibm.samples.websphere.osgi.colors.eba,
the core colors sample enterprise bundle archive.
- com.ibm.samples.websphere.osgi.colors.blender_1.0.1.jar,
an updated version of one of the bundles inside the colors sample
application
- com.ibm.samples.websphere.osgi.colors.brightness.extension.cba,
a composite bundle archive that you can use to extend the colors sample
application.
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.
