Re: [m2e-users] m2e-wtp, war overlays and shared resources
|
Hi,
> Can you link to a sample project reproducing the issue?
Sorry for the late reply; I didn't manage to come
back earlier...
Anyway, I've attached a simple project with which
you can reproduce the behaviour: When you import the main module in Eclipse,
the Jar module has to be converted manually to a faceted project and marked
as being a utility module.
When configured correctly and you start the EAR inside
Wildfly for example, enter "http://localhost:8080/foo"
in your browser and you see a simple HTML page saying "Hello World".

Thorsten
