(I've tried using "pre"-tags and also html-commenting to get the XML to be quoted.  I don't have time to work out how to do a transformation of the less-than and greater-than chars to charater-entities.  Perhaps I can provide such at some later time, if necessary -- perhaps by email-attachment.  Suffice it to say that the Java-code, up to a point, seems to be "seeing", in terms of element-names and attribute-names, the XML that the salesforce server is sending, but then there's some problem apparently having to do with the difference between local-names and qualified-names).

Hi,

 

    Where did you get SForceUtil.java.  Is it part of client of sforce using the Apache Soap 2.2 APIs.

 

    Thanks.
