[google-appengine] Re: Compressed string extractable in appengine?

2008-11-20 Thread Daniel O'Brien (Google) 

The following should work, if you haven't tried something along these
lines already.

Java:

String inputString = Hello, world!;
byte[] input = inputString.getBytes(UTF-8);

byte[] output = new byte[100];
Deflater compresser = new Deflater();
compresser.setInput(input);
compresser.finish();
compresser.deflate(output);

FileOutputStream out = null;
try {
  out = new FileOutputStream(some_temp_file);
  out.write(output);
} finally {
  out.close();
}

Python:

import zlib
zlib.decompress(data)
print data

Let me know if you run into any trouble,

Daniel

 Hi,

 I want to create a compressed String in Java and send it to the
 appengine where it is decompressed. Can somebody help me to do this?

 So far I used GZIP for compression in Java. Extraction in appengine
 didn't work though.

 Using the ZIP format in Java resulted also in not more luck. Does
 somebody have example codes on both sides that is known to work?

 Thanks a lot!
