I haven’t used Netbeans JAX binding for over a year.
And the last time I used it, it was easy to find in the plugin menu of Netbeans 6.
Now I’ve upgraded to Netbeans 7 and wasn’t able to find the plugin.
Happily I found a page that advised me to add
to the Update Center.
After that I got a huge list of updates, and my missing JAX-RPC.
Now just: install, restart, update-again.
Et voila, there is the missing “JAXB Binding” menu point that was searching for.
