> The cause for that NullpointerException is that _config.getContextName()_ in
> *EclipseWtpComponent15Writer.java:68* is null.
> I found out that you are referring to *project.getPackaging()* or
> *config.getProject().getPackaging()* instead of *config.getPackaging()* in
> many places:
> * EclipseManifestWriter
> * EclipsePlugin (in this class the method
> _collectWarContextRootsFromReactorEarConfiguration_ should set the missing
> context name, but the method refers to *project.getPackaging()* which is
> still *jar*
> ** here a _reactorProject.getPackaging()_ can also be fond, I don't know if
> this is correct.
> * RadManifestWriter
> * MyEclipseMetadataWriter
> * MyEclipseStrutsDataWriter
> * EclipseWtpApplicationXMLWriter
> * MyEclipsePlugin
> * AbstractWtpResourceWriter
> After replacing all references to project.getPackaging() to
> config.getPackaging() the NullpointerException has gone and the plugin works
> as expected.
> I did only test the combination of project-packaging=jar and
> eclipse-packaging=war for Eclipse. I did not test MyEclipse, RAD and so on..
