I have
a download action implemented
on my Vaadin application but for some reason the downloaded file has the original file's full path as the file
name.
Any idea?
You can see the code
on this post.
Edit:
Here's the important part of the code:
package com.bluecubs.xinco.core.server.vaadin;
import com.bluecubs.xinco.core.server.XincoConfigSingletonServer;
import com.vaadin.Application;
import com.vaadin.terminal.DownloadStream;
import com.vaadin.terminal.FileResource;
import java.io.*;
import java.net.URLEncoder;
import java.util.UUID;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.zip.CRC32;
import java.util.zip.CheckedInputStream;
/**

public class FileDownloadResource extends FileResource {
private final String fileName;
private File download;
private File newFile;
public FileDownloadResource(File sourceFile, String fileName,
Application application) {
super(sourceFile, application);
this.fileName = fileName;
}
protected void cleanup() {
if (newFile != null && newFile.exists()) {
newFile.delete();
}
if (download != null && download.exists() && download.listFiles().length == 0) {
download.delete();
}
}
@Override
public DownloadStream getStream() {
try {
//Copy file to directory for downloading
InputStream in = new CheckedInputStream(new FileInputStream(getSourceFile()),
new CRC32());
download = new File(XincoConfigSingletonServer.getInstance().FileRepositoryPath
+ System.getProperty("file.separator") + UUID.randomUUID().toString());
newFile = new File(download.getAbsolutePath() + System.getProperty("file.separator") + fileName);
download.mkdirs();
OutputStream out = new FileOutputStream(newFile);
newFile.deleteOnExit();
download.deleteOnExit();
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
in.close();
out.close();
final DownloadStream ds = new DownloadStream(
new FileInputStream(newFile), getMIMEType(), fileName);
ds.setParameter("Content-Disposition", "attachment; filename="
+ URLEncoder.encode(fileName, "utf-8"));
ds.setCacheTime(getCacheTime());
return ds;
} catch (final FileNotFoundException ex) {
Logger.getLogger(FileDownloadResource.class.getName()).log(Level.SEVERE, null, ex);
return null;
} catch (IOException ex) {
Logger.getLogger(FileDownloadResource.class.getName()).log(Level.SEVERE, null, ex);
return null;
}
}
}
I already debugged and verified that fileName only contains the file's
name not the whole path.
