Hi,

 

    I have problem in post the SAML response(Browser/Post profile) as base64 encoded format

 

    These are the steps I followed. Please let me know where am I going wrong.

   

    1. used toBase64() of SAMLResponse to get byte[]. Printing its length which is 1795

 

    2. used StringBuffer to get string value of it, printing its length which is 4130. Then post it with a jsp(onload) to another servlet (different tomcat)

            String sb64 = new String();  
            StringBuffer stb64 = new StringBuffer();
              for(int i=0 ; i < sbase64encoded.length ; i++)
              {
                   stb64.append(sbase64encoded[i]);

              }
             sb64= stb64.toString();

    3.  I get the saml response object in that servlet by req.getParameter("SAMLResponse");

         Printing the Length of this string which is 4130

 

    4. I use getBytes() to get byte[]

        printing its length which is again 4130

 

  5.   Now I am sure that there is some thing wrong . After that when I pass this byte[] to accept method of SAMLResponse , it get an exception as follows

 

org.apache.xml.security.exceptions.Base64DecodingException: Illegal byte length; Data to be decoded must be a multiple of 4
Original Exception was java.lang.StringIndexOutOfBoundsException: String index out of range: 4130
