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.
