I'm planning to appear for this certification. From the forum, I understand that RHM would be the best book to follow. But as I understand JAX-RPC has been replaced with JAX-WS which has got better support and enhanced features as listed out in this link
JAX-RPC Vs JAX-WS
Could you please help me on the following points -
1. What is latest version of SCDJWS one should go after
2. Shall I study JAX-WS or JAX-RPC?
3. Which book to refer for the same?
