Creating ZIP archives in Google App Engine (Java) <br />

I face this problem when zipping many files on the production server,
so what should I do to fix it ? is there something can help in GAE
or can I save zip file containing one file on the storage then open
and edit it ? ( to min memory usage)
ByteArrayOutputStream zipBaos = new ByteArrayOutputStream();
ZipOutputStream zipOut = new ZipOutputStream(zipBaos);
byte[] tmpBuf = new byte[1024];
while end of files{
byte[] fileContents = getFileContent(); // it is OK
zipOut.putNextEntry(new ZipEntry(fileNameStr));
ByteArrayInputStream in = new ByteArrayInputStream(fileContents);
int len;
while ((len = in.read(tmpBuf)) > 0) {
out.write(tmpBuf, 0, len);
}
zipOut.closeEntry();}
zipOut.close();
