Which is the best type of web service Rest,Jaxb,XFire etc to develop an big webapplications?

I am developing web application to get read开发者_如何学Pythoning from hardware unit and store it to database it is an big web application so i need to use web services to get reading which will be good to use in netbeans6.9.1.

First of all it depends what web services your hardware supports. If it does not support REST u cant use REST. Check what your hardware supports, it could also be SOAP or even XML/RPC given its a piece of hardware.

If it is REST u could then use Jersey, the JAX-RS implementation that comes with Netbeans. if it is SOAP u can also use JAX-Ws supplied by Netbeans (Metro). CXF (the latest version of xfire) is also a very good option for SOAP, but u have to include the jar files separately and netbeans WS tools wont be available for it (not that i like using them anyway).

Jaxb is just an implementation to transform xml to java and vice versa. Jax-ws uses jaxb, so unless u are transferring plain xml it would be unlikely to use it directly ( u would still need its jars for jaxws)
