When installing a WTP 2.0 milestone into an Eclipse 3.3. milestone, then be sure to manually include the depencies, as currently only EMF is correctly enforced during installation. When dependencies are missing then the Preferences, Server, Installed Runtimes, Add dialog is rendered incomplete (little red squares instead of server icons, and no JBoss servers listed). For Eclipse 3.3 M6: Help, Software Updates, Find and Install Search for New Features, Europa Discovery Site Graphical Editors and Frameworks: Graphical Editing Framework (GEF) Models and Model Development: Eclipse Modeling Framework (EMF), EMF Service Data Objects (SDO), XML Schema Infoset Model (XSD) Web and JEE Development: Web Standard Tools (WST), J2EE Standard Tools (JST) The choices at Preferences, Server, Installed Runtimes, Add should now include some JBoss servers. If your preferred version does not show in the list, then: Download Wolfgang Knauf's WTP 2.0 Server definition for JBoss 4.2.0 or 5.0.0 (see also WTP bug 128444) Copy into eclipse/plugins Restart Eclipse using the -clean command line option Enjoy, Arjan.
