Question

File upload problem

Asked by: vijayneema

Hi All,

I am writing a page from where a user can upload a zip file & my page will first validate the zip file & if it is valid then only it will be saved in actual folder. Please see my piece of code below, the problem i am getting is i am able to save the file in temp folder but when i try to read it for validation it gives this error :

java.util.zip.ZipException: error in opening zip file
        at java.util.zip.ZipFile.open(Native Method)
        at java.util.zip.ZipFile.<init>(ZipFile.java:62)
        at java.util.zip.ZipFile.<init>(ZipFile.java:77)

Thanks in advance

Here is my code :
FileOutputStream fileOutput = new FileOutputStream(tmpFileName);
FSRUtil.copy(is, fileOutput); // "is" is a inputStream object, this statement create the file in tmp folder.
fileOutput.close();
fileOutput = null;

File file = new File(tmpFileName);
ZipFile zip = new ZipFile(file);  // i am getting error on this line.
Enumeration enum = zip.entries();
for(;enum.hasMoreElements();)
