word doc servlet filename question

[william cipolli]

 
httpServletResponse.reset();
httpServletResponse.setContentType(contentType);
[b]httpServletResponse.setHeader("Content-Disposition", "inline; filename=\"" + original_filename + "\""  );[/b]
httpServletResponse.setContentLength(content.length);
ServletOutputStream stream = httpServletResponse.getOutputStream();
stream.write(content);
stream.flush();
stream.close();

At this point when you click the word download link it opens the download popup with the correct filename printed. If save is clicked it will open the save as box with the correct filename. BUT if we hit open the word doc opens and its title is the servlet name: "WordServlet(Read-Only)"

I am using IE 6!!

Hi william,

This can help you ....

 
package com;

import java.io.DataInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * @author computer

 */
public class DownLoadServlet extends HttpServlet {
	public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException,ServletException{
		try{
		int length=0;
		File f= new File("D:\\helo.doc");
		res.setContentType("application/vnd.ms-word");
		res.setHeader("Content-Disposition", "attachment;filename=\""+f.getName()+"\"");
		
		byte[] bbuf = new byte[4096];
        DataInputStream in = new DataInputStream(new FileInputStream(f));
        ServletOutputStream sos = res.getOutputStream();
        while ((in != null) && ((length = in.read(bbuf)) != -1))
        {
        	sos.write(bbuf,0,length);
        }

        
        in.close();
        sos.flush();
        res.flushBuffer();
        sos.close();
		}catch(Exception exec){
			exec.printStackTrace();
		}
	}
}

Regards

Would I have to rewrite my previous doGet method? This servlet does both my word and pdf documents. The issue here isn't with the writeContent? I'm new to the servlet world, so i need some hand holding to understand this throughly.

Hi,

No need to rewrite doGet() method,
Just replace the line

   
httpServletResponse.setHeader("Content-Disposition", "inline; filename=\"" + original_filename + "\""  );

with

res.setHeader("Content-Disposition", "attachment;filename=\""+ original_filename+"\"");  

or add this line in your code and check it is working fine or not.

   
response.setHeader( "Pragma", "public" );

Keep the other thing same. This will resolve the issue. because "inline" will try to open the attached document in the same browser... where many places IE is not support the "inline"

[william cipolli]

    
private void writeContent(HttpServletResponse httpServletResponse, byte[] content, String contentType) throws IOException {
  if (content != null) {
	httpServletResponse.reset();
	String original_filename = "public";
	//httpServletResponse.setHeader("content-type", contentType);
	httpServletResponse.setContentType(contentType);
[i][u]	httpServletResponse.setHeader("Content-Disposition", "attachment;filename=\""+ original_filename+"\"");[/u][/i]
	httpServletResponse.setContentLength(content.length);
	ServletOutputStream stream = httpServletResponse.getOutputStream();
	stream.write(content);
	stream.flush();
	stream.close();
  }
}

I'm assuming res and response in your code examples were supposed to be httpServletResponse italic and underlined is the code changed. It's still following the same behaivor it was before:
1) prompts user for download with correct name
2) save- saves as correct name
3) opens- as servletname(Read-Only)
4) cancle- cancels dl


3 is the problem

[william cipolli]

    
private void writeContent(HttpServletResponse httpServletResponse,byte[] content, String contentType) throws IOException {
  if (content != null) {
    if(contentType == "application/pdf"){
      httpServletResponse.reset();
      //httpServletResponse.setHeader("content-type", contentType);
      httpServletResponse.setContentType(contentType);
      httpServletResponse.setHeader("Content-Disposition", "inline;");
      httpServletResponse.setContentLength(content.length);
      ServletOutputStream stream = httpServletResponse.getOutputStream();
      stream.write(content);
      stream.flush();
      stream.close();
    }
    else{
      httpServletResponse.reset();
      String original_filename = "Insert form title here";
      //httpServletResponse.setHeader("content-type", contentType);
      httpServletResponse.setContentType(contentType);
      httpServletResponse.setHeader("Content-Disposition", "attachment;filename=\""+ original_filename+"\"");
      httpServletResponse.setContentLength(content.length);
      ServletOutputStream stream = httpServletResponse.getOutputStream();
      stream.write(content);
      stream.flush();
      stream.close();
    }
  }
  else {
    displayMessage(httpServletResponse,ProductCatalogConstants.pdfErrorConditionScript);
  }
}

Here I separated the function instead of using it for both my pdfs and word documents I used selection to pick. The pdfs should use inline to open in a ie window and word docs should load as an attachment. Everything works fine except the open word doc.

if pdf link is clicked pdf opens in new IE window
if word link is clicked download attchment pop up shows
**if open: word doc opens and title is servername(Read-Only)**
if save: opens save as window with correct filename
if cancel: cancels save
