Class HttpServletResponseProxy
- java.lang.Object
- 
- com.ibm.websphere.servlet.response.HttpServletResponseProxy
 
- 
- All Implemented Interfaces:
- javax.servlet.http.HttpServletResponse,- javax.servlet.ServletResponse
 
 public abstract class HttpServletResponseProxy extends java.lang.Object implements javax.servlet.http.HttpServletResponseDeprecated.since WAS V6.0 Use the HttpServletResponseWrapper class instead. Proxies function invocations to an underlying HttpServletResponse. Subclasses of this class can be created that overload or enhance the functionality of a server-provided HttpServletResponse.Using the proxied response:- Subclass this class and overload any desired functions.
- During the servlet's service method, create an instance of the enhanced response using the original response from the server as the proxied response.
- Forward the enhanced response to another servlet for processing instead of the original response that was provided by the server.
 Sample subclass (overloads the response's OutputStream)//The data written to this response will be saved to the specified file. public class FileOutputResponse extends HttpServletResponseProxy{ private HttpServletResponse _response; private File _file; public FileOutputResponse(File f, HttpServletResponse resp){ _file = f; _response = resp; } protected HttpServletResponse getProxiedHttpServletResponse(){ return _response; } //overload response functionality public ServletOutputStream getOutputStream() throws IOException{ return new ServletOutputStreamAdapter(new FileOutputStream(_file)); } public PrintWriter getWriter() throws IOException{ return new PrintWriter(getOutputStream()); } }Using the enhanced response subclass transparently in a servlet//This servlet will store the response of another servlet to a file. public class SaveResponseToFileServlet extends HttpServlet{ public void service(HttpServletRequest req, HttpServletResponse resp){ resp = new FileOutputResponse(req, new File("/tmp/response.txt")); //store the response of SnoopServlet to the response.txt file. getServletContext().getRequestDispatcher("/servlet/SnoopServlet").forward(req, resp); } }
