This feature enables OSGi applications that contain Web Application Bundles (WABs). Web application bundles are OSGi bundles that are internally structured in the same way as a war file and support the same web components.
To enable the OSGi Web Application Bundles feature, add the following element declaration inside the featureManager element in your server.xml file:
<feature>wab-1.0</feature>
If you are developing a feature that depends on the OSGi Web Application Bundles feature, include the following item in the Subsystem-Content header in the feature manifest file for your new feature:
com.ibm.websphere.appserver.wab-1.0; type="osgi.subsystem.feature"
