Why ZipInputStream can't read the output of ZipOutputStream?

Question

I\'m stuck with this junit test:

public void test() throws Exception {
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    ZipOutputStream zipOu

Read API doc for ZipEntry. It says "if known". You can read the content using the following (it just prints the size of the zipentry, change it process data appropriately):

ZipEntry entry = zipIn.getNextEntry();
int BUFSIZE = 1024;
byte [] buffer = new byte[BUFSIZE];
int read = 0;
int total = 0;
while( (read = zipIn.read(buffer, 0, BUFSIZE)) >0 ) { 
  total += read;
  // what do you want to do with the data read? Do it here
}   
System.err.println("Total: " + total);
