Converting a singned decimal to a hexed String ?

Hi...

what i'm trying to do is to convert a buffer[8] which is filled with signed decimal values to a String Hex represenation of it.... This is the code i'm doing ..

/CODE/

for(int i = 0; i < 8; i++)

{

String serialStr = "";

serialStr = serialStr.concat( Integer.toHexString(hashed_Output) );

}

/CODE/

Now the return value of serialStr is the rigth hex values of hashed_Output[] but i get each value as ffffffCf let's say instead of only Cf. I guess because the value i'm reading is signed. Do u have any idea how to read those signed values to a string as hex and only show Cf ?

Please let me know...
