Hi Team,

        In our source code (a servlet running in Websphere 5 Test Environment), when we were trying to sign a SAMLResponse Object we are getting the following error:

[4/28/04 16:58:52:400 GMT-07:00] 69d7c67a WebGroup      E SRVE0026E: [Servlet Error]-[java.lang.Exception: method &lt;init&gt;&#40;Ljava/lang/String&#59;Ljava/lang/Throwable&#59;&#41;V not found]: java.lang.NoSuchMethodError: java.lang.Exception: method <init>(Ljava/lang/String;Ljava/lang/Throwable;)V not found

Following is the code snippet, which throws that error:

**********
                        resp.sign(
                            XMLSignature.ALGO_ID_SIGNATURE_DSA,                    
                            ks.getKey(alias,password),
                            Arrays.asList(ks.getCertificateChain(alias))
                            );

where resp is a SAMLResponse

**********

        We were not able to identify the root cause of this problem, as this works perfectly fine in a stand alone java program.

        Please help us to resolve this problem. Please call me if you have any questions at the below given number.

Thanks & Best Regards,
