I've got a form that allows a user to upload up to five images to an
action. Generally it all works fine. In the action, I iterate over
the List<FileBean> and make my own copy of each file.
private List<FileBean> files;
public List<FileBean> getFiles() { return files; }
public void setFiles(final List<FileBean> files) { this.files = files; }
private List<FileWithName> getStableFiles() {
try {
return new ArrayList() {{
for (FileBean fb : getFiles()) {
if (fb == null) continue;
final File file =
File.createTempFile("receipt", ".tmp");
fb.save(file);
add(new FileWithName(file,
fb.getFileName()));
}
}};
}
catch (IOException ioe) {
for (FileBean fb : getFiles()) try { fb.delete(); }
catch(IOException pointless) {}
throw new RuntimeException("Error handling uploaded
receipts", ioe);
}
}
I'm noticing however that things go wrong when an upload includes two
files (each in a different client machine directory) with the same
name. When that happens, I get this exception from inside the
FileBean:
Caused by: java.io.IOException: Some time between uploading and saving
we lost the file
/tmp/Jetty_0_0_0_0_38080_t.war__t__.p7dy5c/newlogo.png - where did it
go?.
at net.sourceforge.stripes.action.FileBean.save(FileBean.java:155)
at
tango.ui.action.account_holder.receipts.Upload$1.<init>(Upload.java:48)
at
tango.ui.action.account_holder.receipts.Upload.getStableFiles(Upload.java:44)
In this case, I had /tmp/newlogo.png and /home/m5/tmp/newlogo.png in
the upload list.
I'm still on 1.5.1 btw. Or is it 1.5? It's whatever wasn't released recently.
