I get NAMESPACE_ERR exceptions when using Spring-WS. What can I do about it?

If you get the following Exception:

NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.
               

Most often, this exception is related to an older version of Xalan being used. Make sure to upgrade to 2.7.0.

我的做法是 remove server 端的 xalan 2.7以下的jar
