Hi all,
I could successfully build the sample client SSO application in Java
and deploy on tomcat. The environment is:
JDK/JRE: 1.4.2
Tomcat: 5.5.16
However, the same application when deployed on a SAP Netweaver
instance fails. When I click on "Generate SAML Response" button, it
gives the following error on the browser:
Error signing SAML element: class configured for TransformService:
org.jcp.xml.dsig.internal.dom.DOMEnvelopedTransform not a
TransformService
I investigated and found the error to come from XmlDigitalSigner.java
file in the lines:
XMLSignatureFactory sigFactory = XMLSignatureFactory.getInstance
("DOM",
(Provider) Class.forName(providerName).newInstance());
// Create a Reference to the enveloped document (we are
// signing the whole document, so a URI of "" signifies that) and
// also specify the SHA1 digest algorithm and the ENVELOPED
Transform.
List envelopedTransform = Collections.singletonList(sigFactory
.newTransform(Transform.ENVELOPED, (TransformParameterSpec)
null));
I am not sure why this works in JRE 1.4.2 in Tomcat, but fails in the
the same JRE version in Netweaver. Any clues?
Just a thought: Does the Servlet API version have any impact on this?
Thanks.
