You can use the following method to decompress the incoming request.

public static byte[] getinflatedString(byte[] byteArray) throws Exception {
   
        byte[] unCompBytes = null;
        ByteArrayOutputStream byteArrOtptStr = null;
        try {
            Inflater inflater = new Inflater(true);
            inflater.setInput(byteArray);

            byteArrOtptStr = new ByteArrayOutputStream(byteArray.length);

            byte[] buf = new byte[1024];
            while (!inflater.finished()) {
                int count = inflater.inflate(buf);
                byteArrOtptStr.write(buf, 0, count);
            }

            unCompBytes = byteArrOtptStr.toByteArray();
        } finally {
            byteArrOtptStr.close();
        }
        
        return unCompBytes;
    }

after you deflate the incoming request, convert it to XML element.
Then use the Unmarshaller to parse the element into corresponding openSAML object (like AuthneticationReqest object etc).

Hope it helps.

I am wondering if anyone can tell me how to best validate the signature when using the HTTPRedirectDeflateDecoder? I have searched around and looked in the opensaml tests and am unable to figure it out.

Thanks in advance,
