Class WebAppServletHost

java.lang.Object
  org.apache.tuscany.sca.host.webapp.WebAppServletHost

All Implemented Interfaces:

ServletHost

public class WebAppServletHost
extends java.lang.Object
implements ServletHost

ServletHost implementation for use in a webapp environment. FIXME: using a static singleton seems a big hack but how should it be shared? Need some way for TuscanyServlet to pull it out.

Field Summary

static java.lang.String

SCA_DOMAIN_ATTRIBUTE

Method Summary

void	addServletMapping(java.lang.String suri, Servlet servlet) Add a mapping for an instance of a Servlet.
java.lang.String	getContextPath() Returns the portion of the request URI that indicates the context of the request
java.lang.String	getContributionRoot()
protected java.lang.String	getContributionRoot(ServletContext servletContext)
int	getDefaultPort() Returns the default port for the server.
static WebAppServletHost	getInstance()
RequestDispatcher	getRequestDispatcher(java.lang.String suri) Returns a Servlet request dispatcher for the Servlet mapped to the specified URI.
Servlet	getServletMapping(java.lang.String suri) Returns the Servlet mapped to the given URI.
java.net.URL	getURLMapping(java.lang.String suri) Returns the complete URL mapped to the specified URI.
void	init(ServletConfig config)
void	initContextPath(ServletConfig config) Initializes the contextPath The 2.5 Servlet API has a getter for this, for pre 2.5 Servlet containers use an init parameter.
Servlet	removeServletMapping(java.lang.String suri) Remove a Servlet mapping.
void	setAttribute(java.lang.String name, java.lang.Object value)
void	setContextPath(java.lang.String path) Sets the portion of the request URI that indicates the context of the request
void	setContextPath2(java.lang.String path) TODO: How context paths work is still up in the air so for now this hacks in a path that gets some samples working can't use setContextPath as NodeImpl calls that later
void	setDefaultPort(int port) Sets the default port for the server.
