com.ibm.websphere.servlet.request.HttpServletRequestProxy
since WAS V6.0
Use the HttpServletRequestWrapper class instead.
Proxies function invocations to an underlying HttpServletRequest.
Subclasses of this class can be created that overload or enhance the
functionality of a server-provided HttpServletRequest.
Using the proxied request:
Sample subclass (overloads the request's InputStream)// This enhanced request will force the request to be a POST request. // This request POST data input will be read from a specified file. public class PostedFileRequest extends HttpServletRequestProxy{ private HttpServletRequest _request; private File _file; public PostedFileRequest(File f, HttpServletRequest req){ _file =f; _request = req; } protected HttpServletRequest getProxiedHttpServletRequest(){ return _request; } //overload request functionality public ServletInputStream getInputStream() throws IOException{ return new ServletInputStreamAdapter(new FileInputStream(_file)); } public BufferedReader getReader() throws IOException{ return new BufferedReader(getInputStream()); } public String getMethod(){ //force the HTTP method to be POST. return "POST"; } } Using the enhanced request subclass transparently in a servlet//This servlet posts a data file as a request to another servlet. public class PostGeneratorServlet extends HttpServlet{ public void service HttpServletRequest req, HttpServletResponse resp){ req = new PostedFileRequest(req, new File(request.getPathTranslated())); //forward the enhanced request to be used transparently by another servlet. getServletContext().getRequestDispatcher("/postHandlerServlet").forward(req, resp); } } |
com.ibm.websphere.servlet.response.HttpServletResponseProxy
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:
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); } } |
com.ibm.websphere.servlet.filter.ServletChain
Application developers requiring this functionality
