Hi Mike,

Unfortunately there no other way. You might have been able to generate
the interface using earlier wsimport but during runtime it would fail
evetually.

Problem is JAXWS dispatches based on the qname of the element. If you
have multiple operations that references same global element the
dispatch would fail during runtime.

Based on the user feed back where earlier jaxws bits used to fail at
runtime given the case where multiple operations references the same
element, we chose to give this as error at the design time so that users
can fix the problem before deployment.

Also, WS-I BP requires[1] wire signature uniqueness among operations in
a portType. So having different element for each operation would mean
more interoperability with the clients that are developed using
something other than jaxws.

Granted I can create an extra element from the underlying complex type to resolve this, but is there another way? Another one of my ports will have approximately 30 operations, most with a single element type. I didn't run across this problem with previous versions.
