New Help for Old Friends VII

This page collects notes and pointers to changes coming up in the WTP 3.4 (Juno) release.

This page acts as a central "jumping off" point for those adopters of WTP that are moving up from a previous version of WTP. Most of this information may be already contained in various mailing lists and Bugzilla reports, but it is believed best to have a central place to get people started. Adopters: if you run into trouble or notice things that are not covered here, please update this page and/or let us know (such as by opening a bug, or sending a note to wtp-dev). Web Tools is a Platform and we strive to provide compatible API evolution with clear migration paths, instructions, etc.

One thing we have learned in the past is that some adopters do not move with us to every new release. Some early adopters went from 0.7 directly to 1.5, for example. Unfortunately, it is difficult to present the information in that way, covering multiple changes across multiple version ranges, so those types of migrations have to read about migrating to each version.

Note: as these notes develop and grow in number, they may occasionally be re-organized into categories, etc.


Java EE

  • The Java Facet can now be installed on more projects than before, specifically on projects also having the Static Web facet, with which it previously conflicted. Discussion can be found in bug 353775, including early configuration issues similar to those that may be encountered by adopters.

Dali

JPA

  • While fixing bug 277017 provisional API was added for resolving a JDT IType for class names specified throughout the JPA model. This would only affect those who have their own implementation of the interfaces listed in the bug.
