Hi,
I am trying to sign a SOAP request (axis) using wss4j + xmlsec libraries.
Following is my client code:
void addSignature(SOAPHeaderElement secHeader) {
WSSecSignature secSign = new WSSecSignature();
secSign.setUserInfo("1","password");
secSign.setSignatureAlgorithm(WSConstants.RSA);
secSign.setKeyIdentifierType(WSConstants.BST_DIRECT_REFERENCE);
WSSecHeader wssh = new WSSecHeader();
wssh.setMustUnderstand(true);
wssh.insertSecurityHeader(secHeader.getOwnerDocument());
try {
secSign.build(secHeader.getOwnerDocument(),CryptoFactory.getInstance(),wssh);
} catch (WSSecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
....
However, i am getting the following exception :
org.apache.ws.security.WSSecurityException: Signature creation failed (Cannot
setup signature data structure)
at
org.apache.ws.security.message.WSSecSignature.prepare(WSSecSignature.java:323)
at
org.apache.ws.security.message.WSSecSignature.build(WSSecSignature.java:643)
...(others)
On debugging, i found the original exception to be:
org.apache.xml.security.exceptions.XMLSecurityException: Cannot create a
http://www.w3.org/2000/09/xmldsig#:ds:SignatureMethod from a
http://www.w3.org/2000/09/xmldsig#:SignatureMethod element
Can someone tell me where the problem is?
Further, in order to do away with these errors for now i made some changes in
xml-sec source (Some different method calls in a few classes). The above error
went away, but now i am getting this:
org.apache.ws.security.WSSecurityException: Signature creation failed; nested
exception is:
java.lang.NullPointerException
