[sudarshan jadhav]

Hello everyone ,
Please help me i am download a server path file at client side using servlet response object but when file open and save dialog box open and click on save or open button the error is display at tomcat server file not found .My code is working successful and delete a file from server path but at console file not found exception is display 2 times why 2 times java file is called and error is display at console
My code is follow one jsp and one servlet file is:

<FORM ENCTYPE="multipart/form-data" ACTION="FileDownloadServlet" id="myform" 
		METHOD=GET>
		<center>
		<div id="div">
			<table border="0"  id="table">
 				<tr>
 					<center>
 						<td  ><B>DOWNLOAD FILE</B>
 						<center></td>
 				</tr>
 				<tr>
 					<td  ></td>
 				</tr>
 				<tr>
 					<td><b>File To Download:</b></td>
 					
 					<td><INPUT  NAME="reportName" TYPE="reportName" readonly="readonly" value=<%=fname%>></td>
 				</tr>
 			
 					<td  ></td>
 				</tr>
 				<tr>
 					<td  ><input type="submit"
 						value="Save File" onclick="hidetable()"></td>
 				</tr>
 				
 			</center>
 			</table>
			</div>
		</FORM>

when click on submit button a server path file is download to client browser using respose object of servlet. The FileDownloadServlet.java is as:

           protected void doGet(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		try{
			String fileName = req.getParameter("reportName");
			System.out.println("path:"+fileName);
			File f = new File(fileName);
			int length   = 0;
			ServletOutputStream op = resp.getOutputStream();
			ServletContext context  = getServletConfig().getServletContext();
			String mimetype = context.getMimeType(f.getName());
			String fileName1=fileName.substring(14,fileName.length());
			System.out.println("file name:"+fileName1);
			resp.setContentType( (mimetype != null) ? mimetype : "application/octet-stream" );
			resp.setContentLength( (int)f.length() );
			resp.setHeader( "Content-Disposition", "attachment; filename="+fileName1 );
			byte[] bbuf = new byte[1024];
			DataInputStream in = new DataInputStream(new FileInputStream(f));

			while ((in != null) && ((length = in.read(bbuf)) != -1))
			{
				op.write(bbuf,0,length);
			}
			in.close();
			op.flush();
			op.close();
			f.delete();

		}catch(Exception e){
			e.printStackTrace();
		}
	}

my tomcat server display error message as follow:

Why the filedownloadservlet.java file call two times when click on open or save file dialog button at client side browser

[nalla srinivas]

put the downloaded file in the tomcat root dierectory or get the file object using getResource() from the servlet context object.

refer servletContext methods you will get a solution.

Thank you nalla srinivas for reply
I have create a file at c:\XMLFiles\filename.xml server path successfully but when access these file to client side computer click on save button browser show file save dialog box is open a save or open button click the file is save or open successfully at client side but the problem is servlet code i.e. FileDownloadServlet.java is run two times and error message is display at tomcat file not found at c:\XMLFiles\filename.xml because the file is save at client side after that process server side same file is deleted successfully and error is display at console.

What is "hidetable()" function??? Maybe problem arise because of it!!!

                <tr>  
                    <td  ><input type="submit"  
                        value="Save File" onclick="hidetable()"></td>  
                </tr>
