Hi,<br><br>I am following this wiki: <a href="https://wiki.shibboleth.net/confluence/display/OpenSAML/OSTwoUserManJavaDSIG">https://wiki.shibboleth.net/confluence/display/OpenSAML/OSTwoUserManJavaDSIG</a>, to create signature for a saml object, here is my code:<br>

<br><br><br>public void createSignature( KeyStoreManager keyStore, SignableXMLObject samlObject ) throws GeneralSecurityException, SecurityException, MarshallingException, SignatureException<br>    {<br>        Credential signingCredential = SecurityHelper.getSimpleCredential( (X509Certificate)keyStore.getCertificate(), keyStore.getPrivateKey() );<br>

<br>        Signature signature = createSAMLObject( Signature.class );//a wrapper to create a saml object easier.<br>        signature.setSigningCredential(signingCredential);<br><br>        // This is also the default if a null SecurityConfiguration is specified<br>

        SecurityConfiguration secConfig = Configuration.getGlobalSecurityConfiguration();<br>        // If null this would result in the default KeyInfoGenerator being used<br>        String keyInfoGeneratorProfile = &quot;XMLSignature&quot;;<br>

<br>        SecurityHelper.prepareSignatureParams(signature, signingCredential, secConfig, keyInfoGeneratorProfile);<br>        <br>        samlObject.setSignature(signature);<br>        <br>        marshallMessage( samlObject );<br>

        Signer.signObject( signature );<br>    }<br><br>When I use it, it always give me this exception:<br><br>Caused by: java.lang.IllegalArgumentException: Manager with name &#39;XMLSignature&#39; does not exist<br>    at org.opensaml.xml.security.keyinfo.NamedKeyInfoGeneratorManager.getFactory(NamedKeyInfoGeneratorManager.java:157)<br>
