They are fixed now, which is a Good Thing. @Craig Thanks for the update! @Dan I agree: W3C DOM is lame, and dom4j, JDOM, and XOM are better.

Yes, Axiom is another option, and it can be used in Spring-WS as an alternative to SAAJ. It’s an extra dependency, though, and I don’ want to require it. I alsohad issues with Axiom. They are fixed now, which is a Good Thing.

@Craig
Thanks for the update!

@Dan
I agree: W3C DOM is lame, and dom4j, JDOM, and XOM are better. However, I had a couple of reasons to using SAAJ + W3C DOM:

  1. I didn’t feel like writing yet another SOAP message representation. SOAP is hard, let’s go shopping!
  2. It’s the standard, so that means you’re getting some things for free
  3. Using dom4j etc would add another required dependency. Currently, Spring-WS only requires Commons Logging and Spring. Everything else is optional, and I like it that way.

That is not to say I don’t support these alternative dom apis for users, we do. I just don’t want to require them.

Yes there is AXIOM also. AXIOM is better than SAAJ/DOM, but still not a fan of the API. If you want streaming it does that, but if you're doing in memory manipulation its slower &#38; more memory intensive then DOM4J/XOM.
