Constructors Summary

public ResponseIncludeWrapper(ServletContext context, HttpServletRequest request, HttpServletResponse response, ServletOutputStream captureServletOutputStream) Initialize our wrapper with the current HttpServletResponse and ServletOutputStream. param context The servlet context param request The HttpServletResponse to use param response The response to use param captureServletOutputStream The ServletOutputStream to use super(response); this.context = context; this.request = request; this.captureServletOutputStream = captureServletOutputStream;

Methods Summary
public void	addDateHeader(java.lang.String name, long value) super.addDateHeader(name, value); String lname = name.toLowerCase(); if (lname.equals(LAST_MODIFIED)) { lastModified = value; }
public void	addHeader(java.lang.String name, java.lang.String value) super.addHeader(name, value); String lname = name.toLowerCase(); if (lname.equals(LAST_MODIFIED)) { try { lastModified = DateTool.rfc1123Format.parse(value).getTime(); } catch (Throwable ignore) { } } else if (lname.equals(CONTENT_TYPE)) { contentType = value; }
public void	flushOutputStreamOrWriter() Flush the servletOutputStream or printWriter ( only one will be non-null ) This must be called after a requestDispatcher.include, since we can't assume that the included servlet flushed its stream. if (servletOutputStream != null) { servletOutputStream.flush(); } if (printWriter != null) { printWriter.flush(); }
public java.lang.String	getContentType() Returns the value of the content-type header field. return the content type of the resource referenced by this ResponseIncludeWrapper, or null if not known. if (contentType == null) { String url = request.getRequestURI(); String mime = context.getMimeType(url); if (mime != null) { setContentType(mime); } else { // return a safe value setContentType("application/x-octet-stream"); } } return contentType;
public long	getLastModified() Returns the value of the last-modified header field. The result is the number of milliseconds since January 1, 1970 GMT. return the date the resource referenced by this ResponseIncludeWrapper was last modified, or -1 if not known. if (lastModified == -1) { // javadocs say to return -1 if date not known, if you want another // default, put it here return -1; } return lastModified;
public javax.servlet.ServletOutputStream	getOutputStream() Return a OutputStream, throws and exception if a printwriter already been returned. return a OutputStream object exception java.io.IOException if the printwriter already been called if (printWriter == null) { if (servletOutputStream == null) { servletOutputStream = captureServletOutputStream; } return servletOutputStream; } throw new IllegalStateException();
public java.io.PrintWriter	getWriter() Return a printwriter, throws and exception if a OutputStream already been returned. return a PrintWriter object exception java.io.IOException if the outputstream already been called if (servletOutputStream == null) { if (printWriter == null) { setCharacterEncoding(getCharacterEncoding()); printWriter = new PrintWriter( new OutputStreamWriter(captureServletOutputStream, getCharacterEncoding())); } return printWriter; } throw new IllegalStateException();
public void	setContentType(java.lang.String mime) Sets the value of the content-type header field. param mime a mime type contentType = mime; if (contentType != null) { getResponse().setContentType(contentType); }
public void	setDateHeader(java.lang.String name, long value) super.setDateHeader(name, value); String lname = name.toLowerCase(); if (lname.equals(LAST_MODIFIED)) { lastModified = value; }
public void	setHeader(java.lang.String name, java.lang.String value) super.setHeader(name, value); String lname = name.toLowerCase(); if (lname.equals(LAST_MODIFIED)) { try { lastModified = DateTool.rfc1123Format.parse(value).getTime(); } catch (Throwable ignore) { } } else if (lname.equals(CONTENT_TYPE)) { contentType = value; }
public void	setLastModified(long lastModified) Sets the value of the last-modified header field. param lastModified The number of milliseconds since January 1, 1970 GMT. this.lastModified = lastModified; ((HttpServletResponse) getResponse()).setDateHeader(LAST_MODIFIED, lastModified);
