org.apache.beehive.netui.pageflow.ServletContainerAdapter
Adapter interface for plugging into various Servlet containers. An implementor of this interface is "discovered" at runtime. The discovery process is as follows:
- A list of META-INF/services/org.apache.beehive.netui.pageflow.ServletContainerAdapter resources is obtained from classpath. This means, for example, that a file called "org.apache.beehive.netui.pageflow.ServletContainerAdapter" under directory META-INF/services would be found inside any JAR file on classpath.
- Inside each of these resources is the name of a class that implements ServletContainerAdapter. This class is loaded, and its {@link #accept} method is called.
- If {@link #accept} returns true, then that implementation class is chosen as the currentadapter; otherwise, the next one in the list is tried.
- If no adapters are discovered, an instance of {@link DefaultServletContainerAdapter} is used.

            //
            HashMap failoverAttrs = getFailoverAttributesMap( request, false, true );
            if ( failoverAttrs != null )
            {
                ServletContainerAdapter sa = AdapterManager.getServletContainerAdapter( getServletContext() );


                for ( Iterator i = failoverAttrs.entrySet().iterator(); i.hasNext(); )
                {
                    Map.Entry entry = ( Map.Entry ) i.next();
                    if (_log.isTraceEnabled())
                        _log.trace("Ensure failover for attribute " + entry.getKey());


                    // This ThreadLocal value allows others (e.g., an HttpSessionBindingListener like
                    // PageFlowManagedObject) that we're in the middle of committing changes to the session.
                    _isCommittingChanges.set(Boolean.TRUE);
