I had a similar problem and I solved it with the following ugly kludge. 
Someone who really knows java will probably show us the right way to do
it, but in the meantime this may help:



      byte[] b = new byte[1000000];  //1M= number of bytes in zip entry
      byte[] work_b = new byte[1000000];


         while (ix < 1000000) {
            BytesRead = bis.read (work_b,0,b.length);
            if (BytesRead == -1) {
               break;
            } 
            System.arraycopy(work_b,0,b,ix,BytesRead);
            ix = ix + BytesRead;
         }

The problem I had was that even if the file is greater than a million
bytes, it takes several iterations before the bis.read will return
b.length bytes.  Java seems to pick a number out of a hat for BytesRead
- not sure why.
