Swing/AWT/SWT :: How To Download File Using Dynamic Download Path Name Using FileChooser
Apr 11, 2015
I have a FileChooser:
JFrame parentFrame = new JFrame();
JFileChooser fileChooser = new JFileChooser();
fileChooser.setDialogTitle(txtPushCode.getText());
int userSelection = fileChooser.showSaveDialog(parentFrame);
if (userSelection == JFileChooser.APPROVE_OPTION) {
[Code] ....
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?
I 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());
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.
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.
Java Code:
OutputStream out = null; URLConnection conn; InputStream in = null; long startup = System.currentTimeMillis(); try { URL url = new URL(adress); out = new BufferedOutputStream(

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.

my project is all about downloading files(text files, music files, etc) from a LINUX server using UI build in java, my mentor told me to use HTTP Client (Java apache), but how to start this.
Here's a sample scenario:

Consider the directory structure above.
First, how to connect with this LINUX server using JAVA.
I need to download multiple files from my jsp,My jsp will receive a string array,and in that each array will have a filePath.I ggot the solution to download multiple files by Using ZipOutPutStream,But i don't want to Zip Them,I need to download them in a folder.In that folder i should have all the files.
<c:set var="streamValue" value="${streamValue}"/> <%! void addFile( ZipOutputStream outZip, File f, String name ) { FileInputStream in = null ; try { // Add ZIP entry to output stream. outZip.putNextEntry( new ZipEntry( name ) ) ;
While going through stpring batch,every where there uses pom.xml. But in my office maven repo is blocked. How to get the jar files .
Is there any way to run pom.xml online and download required jar to my local drive. or how to run a pom.xml file after setting maven, I had done all the same but some unknown issues.
I wrote a small Java program called ( "Hello,World ).My next step will be to install this program as an app on my smartphone and I wonder what is involved ?
I have a requirement to download the data from DB to CSV/Excel. What I did is retrieving all the records from DB and store in the List and pass that list to the jsp page. In JSP page, I am using the below setting to download it to CSV/EXCEL.
It was working fine. But I have an issues in it. Excel is capable of storing it only 65,536 rows. Even all the data getting downloaded to CSV/excel (> 65,536), while saving I am getting error from excel saying that it can't save more than 65,536 rows and the below data won't be saved.
This workbook contains data in cells outside of the row and column limit of the selected file format.
Data beyond 256 (IV) columns by 65,536 rows will not be saved. Formula references to data in this region will return a #REF! error.
I am not opt for POI apache third party at this point of time. Is it possible to download it in other sheets if it exceeds the max limit.
Example: Having data of around 100,000.
Download 65,536 - Sheet 1 Remaining in Sheet 2,3.. of the same excel.
InputStream inputStream = null; OutputStream outputStream = null; try { URL url = new URL(imgfm); inputStream = url.openStream(); outputStream = new FileOutputStream(imgto); byte[] buffer = new byte[2048]; int length;

I have several pic to download (e.g 30) however, the code work for some pic (workable for a random number of pic, sometimes workable for 10 pics but sometime can only download 1 pics).
I try to input several println code to found out the problem. finally i found that all the code stop (it's stop as when i use debug process in eclipse, it get no respond) and the final appear code under console is:
We 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(); startTime=cal.getTime(); fis=ftp.downloadFile(ftpclient,separator+resourceID); response.setContentType("application/*"); response.setHeader("Content-Disposition", "attachment; filename="" + downloadFileName + "";"); byte[] bytes = new byte[1024];
am trying to Develop a download manager that will improve the downloading process, by splitting big files into different parts, and download each part of the file parallel and then combine them properly Just like JDownloader not really too complex like it though but more like it especially the split download part of it. I was able to get a script from some eBook but that doesn't really solve my problem as it only downloads pause and resumes which is not really what am looking for.
