[wtp-dev] Facet Problems

[Kevin Bauer <kmbauer@xxxxxxxxxx>]

Hello,

I have just signed up for this mailing
list so I am sorry if this was already covered.  I am working on a
IBM build that is based on the wtp-sdk-I200511111814
WTP build.  I am trying to create a Project Facet.  Here is what
I have tried....


<extension
point="org.eclipse.wst.common.project.facet.core.facets">
  <project-facet
id="web.jstl">
    <label>JSTL</label>
    <description>Add
JSP Standard Tag Library</description>
  </project-facet>

  <project-facet-version
facet="web.jstl"
version="1.0">
    <action
type="install">
         
<delegate
class="com.ibm.etools.webtools.webproject.features.taglibs.internal.JSTLFacetInstallDelegate"/>
        </action>
    <constraint>
        <requires
facet="jst.web"
version="2.2"
allow-newer="true"/>
    </constraint>
  </project-facet-version>

  <project-facet-version
facet="web.jstl"
version="1.1">
    <action
type="install">
         
 <delegate
class="com.ibm.etools.webtools.webproject.features.taglibs.internal.JSTLFacetInstallDelegate"/>
        </action>
    <constraint>
        <requires
facet="jst.web"
version="2.3"
allow-newer="true"/>
    </constraint>
  </project-facet-version>

</extension>

<extension
point="org.eclipse.wst.common.project.facet.core.runtimes">
  <!--
Otherwise: -->
  <supported>
    <runtime-component
any="true"/>
    <facet
id="web.jstl"
version="1.0"/>
    <facet
id="web.jstl"
version="1.1"/>
  </supported>
</extension>

JSTLFacetInstallDelegate
is a very simple delegate that just implements the execute method
of IDelegate

My Facet shows up in the dynamic web
project.  When I select my facet in the UI I get the following error...


java.lang.NullPointerException

I have also tried to create my own config-factory
(even though I do not need to get at user supplied data), but I ran into
some errors.

Thanks for the help,
