Http Service Extensions

Pax Web extends OSGi Http Service in order to align OSGi web support with latest developments of Servlet specs.

In order to make use of this extensions you will have to get hold of a WebContainer service instead of HttpService as in:

bundleContext.getServiceReference( "org.ops4j.pax.web.service.WebContainer" );

Having an WebContainer service instance you will be able to dynamically:

• set context parameters for a Http Context
• register and unregister servlets with multiple url mappings (including wild card '*' support)
• register and unregister filters into the URI namespace of Http Service (including wild card '*' support)
• register and unregister event listeners, for better control over the life cycle of ServletContext, HttpSession and ServletRequest;
• register and unregister error pages
• register and unregister welcome files
• enable and disable JSP support

Accessing the BundleContext

The BundleContext is exposed as attribute of the ServletContext:

BundleContext ctx = (BundleContext) servletContext.getAttribute(
                                WebContainerConstants.BUNDLE_CONTEXT_ATTRIBUTE);
