hi Mario,

hard to say - it would be useful to confirm that AXIS1 when used alone
is ending the XML messages you want. you may also want to enable
tracing/logging in WSIF (and AXIS) to see what is going on.

if possible also please try the latest pre-release 2.1.0 version (it
should have more recent AXIS jar used) from

http://people.apache.org/dist/ws/wsif/

thanks,

alek
