yenc and zip in Java - or bytes[] to String

Ok, I am completly at lost :)

in both cases (my Yenc and zip utilities) i try to do the following

1) get a String
2) transform in byte[]
3) so some computation (either adding value to the byte or passing it to
the ZipOutputStream on a ByteArrayOutput Stream)
4) then transform back into String

In both cases the write(byte[]) does not generate propert stream
I checked Roedy's conversion: http://mindprod.com/jgloss/conversion.html
Still not working :(

Is there anything I am missing ?

*************

public static String compress(String theString) throws Exception{
ByteArrayOutput Stream out = null;
ZipOutputStream zout = null;
String compressedStrin g = null;
byte[] theBytes = theString.getBy tes("8859_1");
CRC32 CRC = new CRC32();
CRC.update(theB ytes);

try {
out = new ByteArrayOutput Stream(theStrin g.length());
zout = new ZipOutputStream (out);
ZipEntry entry = new ZipEntry("strin g");
entry.setCrc(CR C.getValue());
zout.putNextEnt ry(entry);
zout.write(theB ytes,0,theBytes .length);
zout.closeEntry ();
zout.finish();
zout.close();
out.close();
compressedStrin g = new String(out.toBy teArray(),"Cp12 52");
} catch (IOException e){
throw new Exception("Unab le to compress the data.",e);
} finally {
if (zout!=null){
try {zout.close();} catch(Exception e){};
}
}
return compressedStrin g;
}
