OpenSAML user discussion

[Srinivas Padmanabhuni <>]

Hello 

I am new to OpenSAML. Currently trying to use the POST
profile for single sign-on.
I have generated the SAML Response using the API. Then
took the output to a string and am passing it to a
second program to create a SAMLResponse. It throws as
SAXNotRecognizedException.

Details:
org.xml.sax.SAXNotRecognizedException:
http://apache.org/xml/features/validation/schema/normalized-v
alue
        at
org.opensaml.SAMLObject.fromStream(SAMLObject.java:102)
        at
org.opensaml.SAMLResponse.<init>(SAMLResponse.java:139)
        at Test2.main(Test2.java:40)

Earlier tried to convert it to base64 and post it to
SAMLPostProfile and regenerate the SAMLResponse object
using the accept method. That was giving the same
exception as we are getting with this simple program
also. Any pointers will be helpful..
My listing follows:
