Class GrizzlyAdapterChain

java.lang.Object
  com.sun.grizzly.tcp.StaticResourcesAdapter
      com.sun.grizzly.tcp.http11.GrizzlyAdapter
          com.sun.grizzly.tcp.http11.GrizzlyAdapterChain

All Implemented Interfaces:

Adapter

public class GrizzlyAdapterChain
extends GrizzlyAdapter

The GrizzlyAdapterChain class allow the invokation of multiple GrizzlyAdapter every time a new HTTP requests is ready to be handled. Requests are mapped to their associated GrizzlyAdapter at runtime using the mapping information configured when invoking the GrizzlyAdapterChain#addGrizzlyAdapter (com.sun.grizzly.tcp.http11.GrizzlyAdapter, java.lang.String[]) Below is a simple example using two {@link Servlet}

        GrizzlyWebServer ws = new GrizzlyWebServer(path);
        ServletAdapter sa = new ServletAdapter();
        sa.setRootFolder(".");
        sa.setServletInstance(new ServletTest("Adapter-1"));
        ws.addGrizzlyAdapter(sa, new String[]{"/Adapter-1"});

        ServletAdapter sa2 = new ServletAdapter();
        sa2.setRootFolder("/tmp");
        sa2.setServletInstance(new ServletTest("Adapter-2"));
        ws.addGrizzlyAdapter(sa2, new String[]{"/Adapter-2"});

        System.out.println("Grizzly WebServer listening on port 8080");
        ws.start();
 
 

Note: This class is NOT thread-safe, so make sure you synchronize when dynamically adding and removing {@link GrizzlyAdapter}

Parameters:

adapter - GrizzlyAdapter instance

mappings - an array of mapping.
