Inconsitency in zipInputStream

Question

hi
i'm trying to use java.util.zip API. here i see inconsistency while using ZipInputStream.read i.e it doesn't return the exact length for larger files.
in the following code, the value of entrySize(this value is acurate) and readCount (this value is wrong) doesn't match for larger files in the zip folder but smaller files (>12kb) doesn't have this issue ... as a result in the output , the data in the larger files are truncated.
any idea/solution?
long entrySize = entry1.getSize();
                         Debug.logInfo("entry size"+ entrySize);
                         byte[] data = null;
                         if(entrySize <= 0){
                              data = new byte[1024];
                         }else{
                              data = new byte[new Long(entrySize).intValue()];
                          int readCount = zipInputStream.read(data, 0, data.length);
                          docxOutFile.putNextEntry(new ZipEntry(entry1.getName()));
                          docxOutFile.write(data, 0, readCount);
                          docxOutFile.closeEntry();Edited by: sunnySide-LDC on Oct 30, 2008 4:18 PM

Answer 1

Where does it say that read() has to return the same length you asked for?
Try this:
int readCount;
while ((readCount = in.read(buffer)) > 0)
  out.write(buffer, 0, readCount);Works every time, for any buffer size > 0, and every kind of stream.
