Hi,
it seems that it's no possible to browse a file from client filesystem
using something like FileDialog. My need is to browse a file and upload
it on a server. My idea is to use a browser widget in which i load a
jsp/servlet that manages uploading. Are there others ideas to make this job?
Thanks
Christian

I impleted my File upload/download system with rap internal Browser +
servlet.
upload dialog：
public class FileUploadDialog extends TitleAreaDialog {
private Browser browser;
public FileUploadDialog(Shell parentShell) {
super(parentShell);
}
/**
* Create contents of the dialog
* @param parent
*/
@Override
protected Control createDialogArea(Composite parent) {
Composite area = (Composite) super.createDialogArea(parent);
Composite container = new Composite(area, SWT.NONE);
container.setLayout(new FillLayout());
container.setLayoutData(new GridData(GridData.FILL_BOTH));
browser = new Browser(container, SWT.NONE);
String url =
"http://"+RWT.getRequest().getServerName()+":"+RWT.getRequest().getServerPort()+ "/web/fileupload.jsp";
String html = "<?xml version=\"1.0\" encoding=\"utf-8\"
?><html><head><title>upload file</title></head><body>"+
"<form action=\""+url+"\" enctype=\"MULTIPART/FORM-DATA\"
method=\"post\"><br />File Name:</br><input type=\"file\""+
" name=\"filename\"/><br><input type=\"submit\"
value=\"upload\"/></form></body></html> ";
browser.setText(html);
setMessage("select a local file");
return area;
}
/**
* Return the initial size of the dialog
*/
@Override
protected Point getInitialSize() {
return new Point(382, 280);
}
protected void configureShell(Shell newShell) {
super.configureShell(newShell);
newShell.setText("upload file");
}
}
file upload sevlet:
public class FileUploadServlet extends HttpServlet {
private static final long serialVersionUID = -7245361228773015964L;
private String uploadPath = "/upload/"; // server file repository
private String tempPath = "/upload/tmp/"; //temp file folder
public void doPost(HttpServletRequest request, HttpServletResponse
response)
throws IOException, ServletException {
try {
DiskFileUpload fu = new DiskFileUpload();
// max file size
fu.setSizeMax(-1);
// buffer size
fu.setSizeThreshold(4096);
// temp path
fu.setRepositoryPath(tempPath);
// get all uploa file
List fileItems = fu.parseRequest(request);
Iterator i = fileItems.iterator();
while (i.hasNext()) {
FileItem fi = (FileItem) i.next();
// get the upload file name
String fileName = fi.getName();
String sep = System.getProperty("file.separator");
int index = fileName.lastIndexOf(sep);
if(index >-1){
fileName = fileName.substring(fileName.lastIndexOf(sep));
}
fi.write(new File(uploadPath + fileName));
response.getWriter().println(fileName+"upload success");
}
} catch (Exception e) {
//do something?
e.printStackTrace();
}
}
public void init() throws ServletException {
if (!new File(uploadPath).isDirectory())
new File(uploadPath).mkdirs();
if (!new File(tempPath).isDirectory())
new File(tempPath).mkdirs();
}
}
registe servlet:
public class HttpServiceTracker extends ServiceTracker {
public HttpServiceTracker(BundleContext context) {
super(context, HttpService.class.getName(), null);
}
public Object addingService(ServiceReference reference) {
final HttpService httpService = (HttpService) context
.getService(reference);
try {
//regist file upload servlet
HttpContext commonContext = new
BundleEntryHttpContext(context
.getBundle(), fileFolder);
httpService.registerResources(fileContext, "/",
commonContext);
Servlet adaptedJspServlet = new ContextPathServletAdaptor(
new FileUploadServlet(),
fileContext);
httpService.registerServlet(fileContext +
"/fileupload.file",
adaptedJspServlet, null, commonContext);
} catch (Exception e) {
e.printStackTrace();
}
return httpService;
}
public void removedService(ServiceReference reference, Object
service)
{
final HttpService httpService = (HttpService) service;
httpService.unregister(fileContext);
httpService.unregister(fileContext + "/fileupload.jsp");
super.removedService(reference, service);
}
}
start servlet:
add these code to the bundle start up method.
public void start(BundleContext context) throws Exception {
super.start(context);
plugin = this;
httpServiceTracker = new HttpServiceTracker(context);
httpServiceTracker.open();
System.out.println("IM resource servlet started...");
}

Tiago,
the code I use (see attachment in my previous post) does the same as
your snippet, but doesn't work.
First of all isFinished() never returns true. But even if, according to
the JavaDoc, the getLastFileUploaded() method returns the client path
name. Besides it seems to never get assigned (Ctrl+Shift+G on
lastFileUploaded field in Upload.java)
Cheers,
Rüdiger

I got it, but this widget provide only a File field for each form, I want
to send more information (such as file properties, keyword) and add multi

Hi Jonh,
If possible, I would suggest something like a 2 steps approach:
- First let the user upload all the files;
- Second allow the user to tag the files with all the extra info
(properties, keywords, ...).
But if needed, you can extend this widget into a custom one.

Joel Oliveira

Hi Tiago,
custom events are currently not supported by RWT. To work around this
you can wrap the event execution in a Runnable and pass it to
ProcessActionRunner#add() like this:
ProcessActionRunner.add( new Runnable() {
public void run() {
// fire event
}
} );
Cheers,
Rüdiger

I have a question about upload widget: Progress bar dispalys normally when the project is lanuched in Eclipse; when the same project is deployed to Jetty composite, no progress displays when running. But no error message in this progress, and the file can be sucessfully uploaded.
Is this a known bug ?
Thanks and Regards,
cheney
