Problem in signing SOAP request

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:

Got my mistake, i was not taking out the document object from SOAPEnvelope as env.getAsDocument(). It is signing the request now.
