Daniel Rohe commented on MECLIPSE-449:
--------------------------------------
The cause of this bug is the creation of the facet file for WTP 1.5 and above.
This file contains entries for fixed facets, the server runtime and installed
facets of a project. The fixed facets depend on the project type and can easily
be added during the creation. For the installed facets the handling currently
uses the dependencies and looks for the servlet-api to determine the version of
the jst.web facet. So one solution is to add the dependency
javax.servlet:servlet-api:2.x to the pom and it works or e.g. use the patch and
override the installed facets using the additional facets configuration element.
There is still a bug when working with RAD because the extended and coexistence
facets are only added to ear-projects but also need to be added to war-projects
and the handling of the server runtime is somewhat buggy.

> Using V2.5.1 of the maven-eclipse-plugin, I have some issues in getting the
> generated artifacts being correct.
> Take this section of the POM:
> <additionalProjectFacets>
> <jst.java>5.0</jst.java>
> <jst.ejb>2.1</jst.ejb>
> <com.ibm.websphere.extended.ejb>6.1</com.ibm.websphere.extended.ejb>
> </additionalProjectFacets>
> Generates this:
> <faceted-project>
> <fixed facet="jst.java"/>
> <fixed facet="jst.utility"/>
> <installed facet="jst.utility" version="1.0"/>
> <installed facet="jst.java" version="5.0"/>
> <installed facet="com.ibm.websphere.extended.ejb" version="6.1"/>
> <installed facet="jst.ejb" version="2.1"/>
> <installed facet="jst.java" version="5.0"/>
> </faceted-project>
> You'll see that the jst.java facet is in there twice.
> Removing the facet from the list:
> <additionalProjectFacets>
> <jst.ejb>2.1</jst.ejb>
> <com.ibm.websphere.extended.ejb>6.1</com.ibm.websphere.extended.ejb>
> </additionalProjectFacets>
> Generates this:
> <faceted-project>
> <fixed facet="jst.java"/>
> <fixed facet="jst.utility"/>
> <installed facet="jst.utility" version="1.0"/>
> <installed facet="jst.java" version="5.0"/>
> <installed facet="com.ibm.websphere.extended.ejb" version="6.1"/>
> <installed facet="jst.ejb" version="2.1"/>
> </faceted-project>
> Which is a little more correct.
> I consider this a bug, as the facets (by their very definition) are unique
> and should not be repeated.
> Additionally, when compared to a RSA (V7) generated one, it is missing the
> standard XML header:
> <?xml version="1.0" encoding="UTF-8"?>
> Also, where does the jst.utility facet come from?
> It's inclusion is getting in the way of RSA recognising it as a true J2EE
> component project (the EJB Deployment descriptor tree element does not
> display in the Project Explorer view in the J2EE Perspective).
> This is the complete RSA generated one, for reference:
> <?xml version="1.0" encoding="UTF-8"?>
> <faceted-project>
> <runtime name="WebSphere Application Server v6.1"/>
> <fixed facet="jst.ejb"/>
> <fixed facet="jst.java"/>
> <installed facet="jst.ejb" version="2.1"/>
> <installed facet="jst.java" version="5.0"/>
> <installed facet="com.ibm.websphere.extended.ejb" version="6.1"/>
> </faceted-project>
> (Which raises another question, how do we specify the runtime items and if
> something is fixed or not?)
> However, to get it to be correctly recognised, all we need is this:
> <faceted-project>
> <fixed facet="jst.java"/>
> <installed facet="jst.java" version="5.0"/>
> <installed facet="jst.ejb" version="2.1"/>
> <installed facet="com.ibm.websphere.extended.ejb" version="6.1"/>
> </faceted-project>
