The below program fails and throws an exception

[frintocf]

The below program fails and throws an exception "Error in opening retrieved zip file". This is only a part of program. I am very new to java. What could be the possiblities to fail and get to catch .

public void unzip_file (String file, String dir, LiblfrEventManager manager) throws LiblfrException {
Enumeration entries;
ZipFile zipFile;

try {
zipFile = new ZipFile(file);

entries = zipFile.entries();

while (entries.hasMoreElements()) {
ZipEntry entry = (ZipEntry)entries.nextElement();

if (entry.isDirectory()) {
// Assume directories are stored parents first then children
//@ TODO manager.progress_notification("Extracting directory: "+entry.getName(), 0);

(new File(entry.getName())).mkdirs();

}
}
entries = zipFile.entries();

while (entries.hasMoreElements()) {
ZipEntry entry = (ZipEntry)entries.nextElement();

if (!entry.isDirectory()) {
//@ TODO manager.progress_notification("Extracting file: "+entry.getName(), 0);
copyInputStream(zipFile.getInputStream(entry), new BufferedOutputStream(new FileOutputStream(dir+"/"+entry.getName())));
}
}

zipFile.close();
} catch (IOException ioe) {
throw new LiblfrException("Error in opening retrieved zip file");
}

You can find it out yourself by making the ioe object print its stacktrace (in your catch block): ioe.printStackTrace(); it tells you exactly what went wrong.

kind regards,
