WSS4J Namespace Problems when signing

Thu, 01 Dec 2005 06:04:16 -0800

Dear Developers,

 

Sorry for pasting on the developer list, but could not find another forum and have a suspicion that this might be a bug.

 

I am trying to do a simple XML-signature, but it seems like the library adds a number of additional namespace tags and the signature is not verified when received by a commercial XML gateway with the following message “The XPath _expression_ has selected no nodes, make sure the namespace and prefix match the required namespace http://www.w3.org/2000/09/xmldsig#”.

 

The code I am using is cut’n’paste from the examples on the website, with some alterations (mustunderstand=false and selection of alias for the keystore) and is included below.

 

Also included are the SOAP-envelope used as input (through a simple parser) and the resulting output. My main concern is the creation of empty xmlns-tags, i.e. xmlns="".

 

Appreciate your time and help,

 

Best regards,

 

Oddbjorn Heimdal
