Serving png from java servlet doesn't show up -

-

I want to return the canvas data as you want to upload an HTML canvas in Java servlet am and PNG image. My problem is that the response to the servlet is not correct and it is not presented as an image. Saving the file works well on the disk.

What am I doing wrong? Do I need to install more headers? Content-length? 

  public void doPost (Acteepisaarlet request, Actiteepisrvet response response) throws IOException {BufferedImage bfi = null; OutputStream Out = Null; PrintWriter htmlOut = null; Try {response.setContentType ("image / png"); String img64 = (string) request.getParameter ("base64image"); Byte [] Decodedbytes = DataType Converter. PRBABBase 64 Binary (IMG64); Bfi = ImageIO.read (new bytereinputstream (decodedbits)); Out = response.getoutputstream (); ImageIO.write (BFI, "PNG", outside); // save on the disk file outputfile = new file ("webpage / saved penda"); ImageIO.write (BFI, "PNG", Output File); } Hold (Exception e) {// Error Handling} Finally {if (bfi! = Null) {bfi.flush (); } If (outside! = Null) {out.flush (); Out.close () ;; } If (html oops! = Null) {htmlOut.close (); }}}}

Maybe I'm blind but I length on materials response object Title.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
