I need to change the default Eclipse WTP "Web Resources" dynamic folder. Currently it points to WebContent, and I need to point to src\main\webapp.
I found the solution:
Under .settings folder in your project's folder, there is a file named "org.eclipse.wst.common.component", inside it change the line <wb-resource deploy-path="/" source-path="/WebContent"/>
with <wb-resource deploy-path="/" source-path="/src/main/webapp"/>
.
That's all!
