Introduction of WTP 2.0 and Eclipse 3.3 in Java EE Tools (New) 

In SAP NetWeaver 7.1 PI, the core of the Java EE toolset is based on the adoption of the Web Tools Platform (WTP) project by Eclipse.org. WTP provides quality tools for Java EE development. In the current release, we introduce WTP 2.0 which provides direct support for Java EE 5 development as well as numerous improvements to its previous version, WTP 1.5. Many of the new features in the Java EE toolset, listed below, come with the introduction of the new release of WTP.

The underlying Eclipse platform is version 3.3 (in the previous release, we used Eclipse 2.0).
