Eclipse Web Tools Platform 2.0 M6
New and Noteworthy

Java EE Tools

Easier publishing of dependencies

Entries on the Java Build Path can now be added to the published structure of J2EE module projects through the J2EE Module Dependencies properties page.

First, add the desired library or classpath container to the Java Build Path


Then select the library so it will be published in the module (Web Library dependencies will be published to /WEB-INF/lib, J2EE Module dependencies will be published to the EAR root)



The resolved contributions from entries published to the EAR root will be displayed in the J2EE Module Dependencies page for the EAR project as grayed items.

Adopters may also make use of corresponding new APIs found in the org.eclipse.jst.j2ee.classpathdep package of the org.eclipse.jst.j2ee plug-in.

More flexible validation

The validation framework now supports Content Types, so additional filename added to content types on the Content Type preference page will also be validated by their respective validators. The J2EE validators already leverage the new content type support with other validators expected to transition by the next milestone.



For adopters, new APIs have been added to the validation framework supporting turning on and off individual validators, translating into increased convenience, utility, and performance.

JSF Tools

Improved HTML DataTable tag variable support

EL variables declared using the "var" attribute on the h:dataTable tag are now recognized by the JSF EL framework. The amount of additional support varies depending on the "value" attribute used to back the variable, the most complete being offered for scalar or array objects with generics planned for the future.

JSF Libraries are now regular Classpath Containers

JSF Libraries now make use of the easier publishing of dependencies feature also introduced in this milestone, so now references to JSF Libraries in a project are made using the Java Build Path and made published/exported using the J2EE Module Dependencies, and will appear as JDT Libraries in the project explorer. An upgrade of the JSF Library Registry will automatically occur when an older workspace is opened. The actual references, however, will require a manual upgrade. Information on this can be found at https://wiki.eclipse.org/index.php/JSF_Library_Migration . JSF Library references are still being created at JSF Facet installation time, but if you need to add, modify, or remove references after project creation, you will now be using the Java Build Path and J2EE Module Dependencies property pages.

Custom JSF Servlet Classname

The JSF servlet classname can now be specified during JSF Facet installation.

JSP

Support for Tag Handlers from Tag files

Custom tags declared by JSP 2.0 tag files are now supported for use by the JSP editor as well as debugging. Support for editing and validating tag files will be added in a future version.

Hyperlinking to custom tag declarations

Activating Hyperlinks within custom tag names will open the tag library descriptor or tag file that declares the custom tag.

Include directive validation

The JSP Syntax Validator now warns when the JSP fragment referred to by an include directive can not be found.
