[fileupload] unable to find setProgress method

[Thomas Favre-Bulle]

Hi everyone !

I'm using fileupload lib in order to implement an upload progress bar.
Unfortunately, it seems there's a problem with
org.apache.commons.fileupload.servlet.ServletFileUpload, each time I try
to compile I get the following error :

symbol  : method setProgressListener(infoserver.control.FileUploadListener)
location: class org.apache.commons.fileupload.servlet.ServletFileUpload
        upload.setProgressListener(listener);
1 error


Here is the code :

FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);

// set file upload progress listener
FileUploadListener listener = new FileUploadListener();
HttpSession session = request.getSession();

session.setAttribute("LISTENER", listener);
       
// upload servlet allows to set upload listener
upload.setProgressListener(listener);


I'm using version 1.2.1 and JDK 1.6.

Any idea ?

Does your infoserver.control.FileUploadListener class implement the
org.apache.commons.fileupload.ProgressListener interface?

Yes it does :

public class FileUploadListener implements ProgressListener {

    private volatile long bytesRead = 0L,  contentLength = 0L,  item = 0L;

    public FileUploadListener() {
        super();
    }

    public void update(long aBytesRead, long aContentLength, int anItem) {
        bytesRead = aBytesRead;
        contentLength = aContentLength;
        item = anItem;
    }

    public long getBytesRead() {
        return bytesRead;
    }

    public long getContentLength() {
        return contentLength;
    }

    public long getItem() {
        return item;
    }



I forgot to add commons.io dependecy but adding it did not solve the
problem.

Then I have no idea what your problem is. I checked the jarfile and it
looks ok:
  javap -classpath commons-fileupload-1.2.1.jar
org.apache.commons.fileupload.FileUploadBase
reports
    public void
setProgressListener(org.apache.commons.fileupload.ProgressListener);
is present.

You could perhaps try
   upload.setProgressListener(
     (org.apache.commons.fileupload.ProgressListener) listener);
just as a test.

Regards, Simon

I found the problem. I removed every jars and add them one by one. There

was a conflict between Struts import of commons.fileupload and the one I
added.
A stupid mistake after all.

Anyway, thanks for your help ! have a nice day
