Class AJP13Listener  

java.lang.Object
  org.mortbay.util.ThreadPool
      org.mortbay.util.ThreadedServer
          org.mortbay.http.ajp.AJP13Listener

All Implemented Interfaces:

org.mortbay.http.HttpListener, org.mortbay.util.LifeCycle, java.io.Serializable

public class AJP13Listener

extends org.mortbay.util.ThreadedServer

implements org.mortbay.http.HttpListener

AJP 1.3 Protocol Listener. This listener takes requests from the mod_jk or mod_jk2 modules used by web servers such as apache and IIS to forward requests to a servlet container.

This code uses the AJP13 code from tomcat3.3 as the protocol specification, but is new implementation.

Method Detail

setHttpServer

public void setHttpServer(org.mortbay.http.HttpServer server)

Description copied from interface: org.mortbay.http.HttpListener

Set the HttpServer instance for this HttpListener. This method is called by the HttpServer.addListener method. It should not be called directly.

Specified by:

setHttpServer in interface org.mortbay.http.HttpListener

---

getHttpServer

public org.mortbay.http.HttpServer getHttpServer()

Description copied from interface: org.mortbay.http.HttpListener

Get the HttpServer instance for this HttpListener.

Specified by:

getHttpServer in interface org.mortbay.http.HttpListener

---

getBufferSize

public int getBufferSize()

Description copied from interface: org.mortbay.http.HttpListener

Get the size of the buffers used by connections from this listener.

Specified by:

getBufferSize in interface org.mortbay.http.HttpListener

---

setBufferSize

public void setBufferSize(int size)

---

getBufferReserve

public int getBufferReserve()

Description copied from interface: org.mortbay.http.HttpListener

Get the size of the header reserve area. Get the size of the header reserve area within the buffers used by connections from this listener. The header reserve is space reserved in the first buffer of a response to allow a HTTP header to be written in the same packet. The reserve should be large enough to avoid moving data to fit the header, but not too large as to waste memory.

Specified by:

getBufferReserve in interface org.mortbay.http.HttpListener

---

setBufferReserve

public void setBufferReserve(int size)

---

getIdentifyListener

public boolean getIdentifyListener()

---

setIdentifyListener

public void setIdentifyListener(boolean identifyListener)

---

getDefaultScheme

public java.lang.String getDefaultScheme()

Description copied from interface: org.mortbay.http.HttpListener

Get the default scheme for requests. If a request is received from a HttpConnection created by this listener, that does not include a scheme in it's request URL, then this method is used to determine the protocol scheme most likely used to connect to this listener.

Specified by:

getDefaultScheme in interface org.mortbay.http.HttpListener

---

start

public void start()
           throws java.lang.Exception

Description copied from interface: org.mortbay.util.LifeCycle

Start the LifeCycle.

Specified by:

start in interface org.mortbay.util.LifeCycle

---

stop

public void stop()
          throws java.lang.InterruptedException

Description copied from interface: org.mortbay.util.LifeCycle

Stop the LifeCycle. The LifeCycle may wait for current activities to complete normally, but it can be interrupted.

Specified by:

stop in interface org.mortbay.util.LifeCycle

---

getRemoteServers

public java.lang.String[] getRemoteServers()

---

setRemoteServers

public void setRemoteServers(java.lang.String[] servers)

Set accepted remote servers. The AJP13 protocol is not secure and contains no authentication. If remote servers are set, then this listener will only accept connections from hosts with matching addresses or hostnames.

---

handleConnection

public void handleConnection(java.net.Socket socket)
                      throws java.io.IOException

Handle Job. Implementation of ThreadPool.handle(), calls handleConnection.

---

createConnection

protected AJP13Connection createConnection(java.net.Socket socket)
                                    throws java.io.IOException

Create an AJP13Connection instance. This method can be used to override the connection instance.

---

customizeRequest

public void customizeRequest(org.mortbay.http.HttpConnection connection,
                             org.mortbay.http.HttpRequest request)

Customize the request from connection. This method extracts the socket from the connection and calls the customizeRequest(Socket,HttpRequest) method.

Specified by:

customizeRequest in interface org.mortbay.http.HttpListener

---

customizeRequest

protected void customizeRequest(java.net.Socket socket,
                                org.mortbay.http.HttpRequest request)

Customize request from socket. Derived versions of SocketListener may specialize this method to customize the request with attributes of the socket used (eg SSL session ids).

---

persistConnection

public void persistConnection(org.mortbay.http.HttpConnection connection)

Persist the connection.

Specified by:

persistConnection in interface org.mortbay.http.HttpListener

---

isLowOnResources

public boolean isLowOnResources()

Description copied from interface: org.mortbay.http.HttpListener

Get the low on resources state of the listener. For most implementations, Threads are the resource reported on by this method.

Specified by:

isLowOnResources in interface org.mortbay.http.HttpListener

---

isOutOfResources

public boolean isOutOfResources()

Description copied from interface: org.mortbay.http.HttpListener

Get the out of resources state of the listener. For most implementations, Threads are the resource reported on by this method.

Specified by:

isOutOfResources in interface org.mortbay.http.HttpListener

---

isIntegral

public boolean isIntegral(org.mortbay.http.HttpConnection connection)

Description copied from interface: org.mortbay.http.HttpListener

Get the integral status of a connection.

Specified by:

---

isConfidential

public boolean isConfidential(org.mortbay.http.HttpConnection connection)

Description copied from interface: org.mortbay.http.HttpListener

isConfidential in interface org.mortbay.http.HttpListener

---

getIntegralScheme

public java.lang.String getIntegralScheme()

Description copied from interface: org.mortbay.http.HttpListener

Specified by:

getIntegralScheme in interface org.mortbay.http.HttpListener

---

setIntegralScheme

public void setIntegralScheme(java.lang.String integralScheme)

---

getIntegralPort

public int getIntegralPort()

Description copied from interface: org.mortbay.http.HttpListener

Get the protocol port to use for integral redirections. If an INTEGRAL security constraint is not met for a request, the request is redirected to an integral port. This port return by this method is used for that redirection.

Specified by:

getIntegralPort in interface org.mortbay.http.HttpListener

---

setIntegralPort

public void setIntegralPort(int integralPort)

---

getConfidentialScheme

public java.lang.String getConfidentialScheme()

Description copied from interface: org.mortbay.http.HttpListener

Get the protocol scheme to use for confidential redirections. If an CONFIDENTIAL security constraint is not met for a request, the request is redirected to an confidential port. This scheme return by this method is used for that redirection.

Specified by:

getConfidentialScheme in interface org.mortbay.http.HttpListener

---

setConfidentialScheme

public void setConfidentialScheme(java.lang.String confidentialScheme)

---

getConfidentialPort

public int getConfidentialPort()

Description copied from interface: org.mortbay.http.HttpListener

Get the protocol port to use for confidential redirections. If an CONFIDENTIAL security constraint is not met for a request, the request is redirected to an confidential port. This port return by this method is used for that redirection.

setConfidentialPort

public void setConfidentialPort(int confidentialPort)

---

getHttpHandler

public org.mortbay.http.HttpHandler getHttpHandler()

Description copied from interface: org.mortbay.http.HttpListener

Get an optional HttpHandler for the listener. If Set, then HttpConnection will pass requests from this listener to this handler with an empty context path, before passing the request to the HttpServer. This allows listener specific handling to be added or even a HttpContext (which is a HttpHandler) to be bound directly to HttpListener.

Specified by:

getHttpHandler in interface org.mortbay.http.HttpListener

---

setHttpHandler

public void setHttpHandler(org.mortbay.http.HttpHandler handler)
