Seeking web services advice

I just got hit with a project that seems like it could use web services. Basically a survey tool that can operate standalone (a Java app) and can sync back to a web server to send survey responses and download more questions. Initially only Windows clients are required, but the ability to expand to others like PDAs would be a nice plus.

Problem is, other than working through a few examples a while back I'm pretty new to web services. And of course I have to have some kind of rough architectural proposal together by COB tomorrow (4/22). I'm looking at a Java client, web based admin, servlets, and a backend DB. Not planning to use EJBs for this. I have a couple of questions right now though if anyone can help.

1) Security - I assume using HTTP as the transport I can use SSL - correct? I'm going to look into WS-Security too, but so far it looks like it's mainly for authentication, and there aren't many (any?) complete implementations available. I think for my rather simple needs I can "roll my own" for authentication if need be. Any other suggestions?

2) Libraries - My first thought was JWSDP, but does it (at least 1.5) only work in certain containers? That's the impression I get from Sun's pages about it. They point you to a special version of Tomcat and two of their commercial offerings. What is there to JWSDP other than a collection of libraries and a few tools that would make it container specific? I'm also looking at Axis - should it work with any container?

Thanks for any and all comments!

1) there are good, working and production ready WS-Security implementations like IBM XSS, Apache WSS4J, VeriSign TSIK etc. All these can support one or more of XML Signatures, XML Encryption, Token Mechnisms, XKMS etc.

2) Apache AXIS should work with any application server since it is just a matter of distributing axis jars in your own project.

Is Apache WSS4J ready for release and download? I don't see any link on their Web site.
 
I agree. Here's the link: http://aspose.com/file-tools
