Eclipse Web Tools Platform 2.0 M5 - New and Noteworthy
Java EE Tools
Java Enterprise Edition 5 Facets
New versions of the EAR, Web, Application Client, and
EJB facets have been added. These versions have been
created to enable developing applications for the Java
Platform, Enterprise Edition 5.
New JSP Content validator
There is now a separate validator for JSP content versus
just using the validator of the embedded content type
within JSP. For example, users are now able to enable
HTML Syntax validation in their HTML files while
disabling JSP content validation (for example HTML
content within a JSP file).
