hi Linus, thanks for the link! after doing some reading, I'm still not sure which category this service falls under. I've attached an edited (identifying info replaced by 'xxxx' and 'yyyy') version of the WSDL for this service.
For reference, I have -Xmx1024m set in the JVM. Have you had any luck with the attachment streaming? I can't figure out how to enable or configure Axis to use it. This is my first time working with Axis, so needless to say I'm fumbling in the dark a little bit. This codebase is larger than any I've worked in the past for a web service, as well. I'm going to continue to investigate and research - I'll post what I find, and hope you'll keep me posted to your progress. cheers, - Jared On 2/2/06, Linus Kamb <[EMAIL PROTECTED]> wrote: > Hi, Jared. > > doc/lit wrapped is the web service "style".
