This problems is not caused by appfuse.
If someone have been encountered this problem please give me some advice.
I wrote an action let user select some file store in the web site and let
them package download by ZipOutputStream.
The problem is the generated zip file can not open because header section is
broken. I have no idea what happen to the action. If I change the
OutputStream from ServletOutputStream to FileOutputStream the generated Zip
file can be open correctly.
I list my ZipOutputStream code as following. The full file is in the
attachment.
Any suggestion will be appreciated.
Best Regards,

CheckedOutputStream checksum = new
CheckedOutputStream(response.getOutputStream(), new Adler32());
ZipOutputStream zos=new ZipOutputStream(new
BufferedOutputStream(checksum));
zos.setMethod(ZipOutputStream.DEFLATED);
for(int i=0;i<selectedAry.size();i++)
{
FileInputStream fileinputstream;
File file = new File(_path.toString());
ZipEntry ze= new ZipEntry(i+"-"+file.getName());
ze.setSize(file.length());
ze.setTime(file.lastModified());
CRC32 crc32 = new CRC32();
int n;
byte [] rgb = new byte [1000];
fileinputstream = new FileInputStream(file);
while ((n = fileinputstream.read(rgb)) > -1)
{
crc32.update(rgb, 0, n);
}
fileinputstream.close();
ze.setCrc(crc32.getValue());
zos.putNextEntry(ze);
fileinputstream = new FileInputStream(file);
BufferedInputStream bis = new BufferedInputStream(fileinputstream);
byte[] bytes = new byte[bis.available()];
bis.read(bytes);
zos.write(bytes);
bis.close();
zos.closeEntry();
}
zos.close();
zos = null;
