streaming an HTML document

[john alexa]

hows it going everyone... i have quite the issue here... it seems simple enough but it has me stumped.

i have a document repository.... people can upload files into it, then click on the file name to view it.....

however, in the case that the user selects an HTML document i am running into some trouble:

it is opening on top of my current application, i have tried target="_blank" etc, etc... but the best ive gotten was for it to open a new blank page...

what i would like to happen is to simply have a new window pop up with the desired HTML document shown....



here is the code in the jsp:

<li <a class="docTree" onclick="document.documentTreeForm.filePath.value='" + currentID + "'; document.documentTreeForm.fileContent.value='" + currentFile.replace("'", "\\'") + "'; document.documentTreeForm.submitAction.value='viewFile'; document.documentTreeForm.submit();" target="" href="javascript: void(0);">" + currentFile + "</a></li>

i pass that into my action which locates the file within my database and sends the data to the following class to stream: (mind you, this works for every other type of document, and i dont have the exact path/location of the HTML document... so this is the only way i can retrieve the data)

	public void streamCity(HttpServletRequest request, HttpServletResponse response, String filePathName) 
			throws IOException
	{
		InputStream in=null;
		BufferedOutputStream bos =null;
		ServletOutputStream out=null;
		try {
			log.debug("INSIDE OF DOCUMENT STREAM.java ---------------------------");
						
			byte[] buff = new byte[8192]; 
			int bytesRead;
			File f = new File(filePathName); 
						
			String outputFilename = f.getName().substring(f.getName().lastIndexOf("/")+1, f.getName().length());
			String fileType = outputFilename.substring(outputFilename.lastIndexOf(".")+1,outputFilename.length());
			
			setContentTypeHelper(response, fileType, outputFilename);
			
			out = response.getOutputStream();
			in = new FileInputStream(f); //if the source is a file
			 bos = new BufferedOutputStream(out);
			 while (-1 != (bytesRead = in.read(buff, 0, buff.length))) { 
				log.debug("in.avail: "+in.available());
				log.debug("buff: " + buff + ".... bytesRead: " + bytesRead);
				bos.write(buff, 0, bytesRead);
			}
				 
			 log.debug("in.avail post loop:::::" + in.available());
			if(in.available() == 0){
				bos.flush();
				bos.close();
				in.close();
			}
			
		} catch (IOException e) {			
			log.error("IOException: "+e);			
		}finally{
			if(in!=null){
				in.close();
			}		
		}
	}

if anyone has any help or hints im open to anything!

thanks a lot,
john

Your HTML is malformed. The <li is missing its >. (In fact, it looks like you just cut it out of some script?)

What are the content-type and content-disposition headers begin set to?

bear,

my JSP code is actually fine, i just was trying to cut out some unneeded portions for my question and edited it poorly... and as you pointed out... i also forgot another chunk of code:

	private void setContentTypeHelper(HttpServletResponse response, String fileType, String fileName)
	{	
		/*if (fileType.contains("html")) {
		response.setContentType("text/html" );
	} else if (fileType.contains("htm")) {
		response.setContentType("text/html" );
	}else{
	*/
			response.setContentType("application/octet-stream");
             //}
			response.setHeader("Content-Disposition","attachment; filename=\""+fileName+"\""); //inline
	}

as you can see above.. i started off attempting to grab the file type but that didnt work any better, so for now everything gets the same content type.

*i should note, that this is only an issue for me in IE, firefox handles it differently.


thanks for your help!
