Question on ZipInputStream and encoding

Hi Guyz,

I am writing client side of a rest web service.
Web Service is returning an InputStream for a zip file which has got 2 entries.
On client side I have to convert this inputstream to a Zip file.I am using ZipInputStream for this.Problem is that I am unable to preserve the encoding - it is all "???" for special characters.
I use this code -

ServletOutputStream sos = response.getOutputStream() ;
ZipOutputStream zos = new ZipOutputStream(sos) ;
ZipInputStream zis = new ZipInputStream(is) ;
ZipEntry entry ;
while(( entry = zis.getNextEntry()) != null){

byte data[] = new byte[BUFFER];
int count ;

ZipEntry entryOut = new ZipEntry(entry.getName()) ;
zos.putNextEntry(entryOut) ;

while ((count = zis.read(data, 0, BUFFER)) != -1) {
zos.write(data,0,count) ;
}

Since we do not have any constructor in ZipInputStream that accepts encoding,I do not know how I can preserve the encoding.
Is there any other way to read the InputStream coming from server side and make it available as zip file?

What encoding is that? And where are those question marks appearing? Since you're not using a Reader or a Writer anywhere it isn't clear to me where an encoding might be used.

Are you sending a ZipFile or are you compressing what you send?

The first one is a normal binary sending of data and can be handles by Base64 or Axis or something similar. Good example is on http://wso2.org/library/1675.

The other one should be more or less what you already do. Todd wrote a good article ages ago so it is quite outdated but the principles are the same (http://www.javaworld.com/javaworld/jw-11-1998/jw-11-howto.html?)
