I have a class that do a soap request to a web service , the response is containing a base64 string repressing a file content , how can i send this string to a servlet (maybe any other way) to send it to the user as a downloaded file .

I have written a code to download .csv file with records from DB.
To download records i am uploading a .CSV file containing telephone number.
After downloading the .CSV file page is not getting refreshed.
Below is the code snippet i am using,where i am setting response content type as test/csv.
ServletOutputStream op = resp.getOutputStream();
// Set content type of output
resp.setContentType("text/csv");
resp.setHeader("Content-Disposition", "attachment; filename="test"");
op.flush();
op.close();
How that page will get refreshed after csv file download or after response.
I have a SOAP Client with wsdl to send a query to a SOAP Server. Along with the SOAP response I am supposed to attach a generated csv file (Not required to open and read - just attach).
SOAP Handler has been implemented at server.
Since it is client code I am not supposed to paste the exact contents online.
I can create new SOAPMessage and use AttachmentPart to attach the file but I am stumped regarding where to set it as response. We have used only javax.xml and apache.cxf.
i'm sending soap request but i'm getting html response it is leading to crash! how to parse html response?

Recently we got an issue about file download. We are using below code to fetch the data from backend(DB2) and export to excel.
Before Jan 15 it use to take 2 minutes to download the file (2 MB size). But now its taking half an hour to download.
response.setContentType("application/vnd.ms-excel");
response.setHeader("content-disposition","attachment; filename=Attendance_Report.xls");
We have restarted server, system but still problem exists. We found that there is no code level or data base level or network level issues.
Now we have to see server level issue. What are the factors which effects the file downloading at server level.
We are using websphere 6.1 ,java1.4
I have a FileChooser:
JFrame parentFrame = new JFrame();
JFileChooser fileChooser = new JFileChooser();

But as you can see, it downloads only to "C:android empcoloricon.png". I want to download it to path where I chose in FileChooser with the name and extension I choose. In short, how can I use dynamic file path names in where ever I want in my applications?
Inspite of not returning anything, what is the purpose of response object in servlet? I have typically used or heard of only response.sendRedirect()

I am creating cash counter application. i want to generate a pdf receipt in new window and print it.
I am using jsp to take input from user and servlets to process the input.
I am able to generate a pdf but in same page. i want it to be a popup menu. How to implement it?
When do i get IllegalStateException in servlets.What it means by trying to write to the output stream (response) after the response has been committed by server. What it means by committing response and uncommitting response. cannot i send uncommitted response.
View Replies View RelatedWe have a website used for downloading large files as large as 6gb and sometimes larger. We have all files in FTP server. The websit is JSP/Servlet /Tomcat combination. Below is code sample. I need a solution to increase the download speed. I understand it is bound to network bandwidth but are the steps that we need to take while we have such large files.I read about multipart downloads,gunzip streaming.
//first connect to FTP server and login and keep connection
Calendar cal=Calendar.getInstance();

I am calling a jsp page from my servlet using the requestdispatcher.forward(myjsp.jsp) method. myjsp.jsp is creating a new thread which is parallely processing along with the servlet. The issue is that the jsp page is not displayed until the servlet finishes its execution, although the new thread is created by jsp and is executing in parallel. How do we have the jsp page displayed even when the servlet is executing.
View Replies View RelatedI am trying to display the files stored in server using jsp. I used the code below to display. But for pdf it is asking to download (No option for open). For XLS, XLSX, DOCX, PPT and PPTX it is showing zip file to download. For type doc it is showing junk data.

String fileName=(String)request.getAttribute("fileName");
int loc = fileName.lastIndexOf(".");
String fileName1 = fileName.substring(0, loc);
String fileName2 = fileName.substring(loc + 1, fileName.length());

New to webservices. Can i get to create webservice which takes xml input. Parse it and gives the response to client.
View Replies View RelatedFor some reasons my servlet doGet method is being called twice. I am calling servlet from the index.jsp page by using servlet annotation "/Profile/*. And it passes path as localhost:1919/Profile/username to getPost method.
<li><a href="Profile/<%=lg.getUsername()%>">Your Profile</a></li>
Servlet Profile retrieves data from the java container stores it as an attribute and forwards to profile.jsp page.
rd = request.getRequestDispatcher("/profile.jsp");
request.setAttribute("ProfileInfo", proInfo);
rd.forward(request, response);
My profile.jsp page uses java code to show all the data (and it shows it perfectly). But then I click link to the next update_profile.jsp page. Just simple link. Then I realize that on this step for strange reasons for me doGet method from Profile servlet is called the second time. And passes path as localhost:1919/Profile/update_profile.jsp
Here is my profile.jsp code:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@ page import="uk.ac.dundee.computing.aec.instagrim.containers.*" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
[Code] ....
And update_profile.jsp file is just simple file with <h1>hello</h1> output. I have looked in the internet that this might be a mapping problem or my css relative path connection problem. As you see I have commented out my css connection and problem still exists. My run output in the IDE also shows these errors:
org.apache.jasper.JasperException: An exception occurred processing JSP page /profile.jsp at line 27
24: %>
25: <article>

And my tomcat run configuration settings: [URL] .... and [URL] ....
String contentType = fi.getContentType(); gives text/plain when my file is.txt file and gives image/jpeg when my file is .jpeg file but when my file is .jar or .docx it will return application/octet-stream and application/vnd.openxmlformats-officedocument.wordprocessingml.document respictively so what to do to get exact mime type.

I currently have the following code that I use to download a file from a website:
URL website = new URL(imgurl);
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream(dir+""+imageNumber + "." + extension);
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
fos.close();
Usually, the code works very well. But sometimes, the download gets stalled indefinitely. Is there a way to set a time out period for the downloading of this file?
Is there a way to measure current download speed of a file being downloaded? I've searched all over google and the only thing i get is average download speed. This is basically how it is being done, the result is average download speed.

OutputStream out = null;
URLConnection conn;
