Hi, as i had started preparing scjws (the older one) 4 months back and unfortunately got interrupted in between. I was referring Monsoon-Haefel book and suggested sites (Mikali notes etc) from this forum. I'm in dilemma whether should i give the older one(310-230, jaxrpc pattern) or the new one (310-231 , jaxws pattern). As per my own experience is concern, i been using jax-rpc protocol for the web service. Will it really matters to do the older one rather than the new one. It would be very helpful or kind if someone really give me the depth details or difference between these two w.r.t the certification. As i'm in between of, so i'm really stuck which one is to opt and will be beneficial to me.
310-231 is an upgrade exam if you already have 310-220.
The diff between the two is majorly as you mentioned JAX-RPC and JAX-WS. It also covers some aspects of WSIT, RESTful WebServices, JASON etc. I would suggest you go for the newer one as JAX-WS has pretty much replaced RPC.
