This feature enables support for deploying OSGi applications that use the OSGi blueprint container specification. With the OSGi Applications support in WebSphere Application Server, you can develop and deploy modular applications that use Java EE and OSGi technologies.
To enable the OSGi Blueprint feature, add the following element declaration inside the featureManager element in your server.xml file:
<feature>blueprint-1.0</feature>
If you are developing a feature that depends on the OSGi Blueprint feature, include the following item in the Subsystem-Content header in the feature manifest file for your new feature:
com.ibm.websphere.appserver.blueprint-1.0; type="osgi.subsystem.feature"
