The document discusses new features for the web front in Java EE 8, including updated Java specifications for Servlets, JAX-RS, JavaServer Faces, and new specifications for JSON processing and binding that add functionality for processing, unmarshalling, and marshalling JSON. It highlights added support for JSON pointers and patches to navigate and modify JSON documents based on IETF standards.

JAX-­‐RS,
Facelets,
BV
– More?
Servlet

Alignment
– @Inject

ExternalContext,
etc.
– CDI
managed

of
Validator

– Rely
on
CDI
for
EL
resolving
– Invoking
CDI
managed
bean
methods
directly
from
Ajax,
etc.
• “Adjustments”
for
MVC
• Misc.
