/NetBeansProjects/CustomerCMP/nbproject/build-impl.xml:187: Deployment error:
Cannot find attribute docBase get method name
See the server log for details.
BUILD FAILED (total time: 2 seconds)

How to reproduce:
------------------
** add GF v2 b57 node (happens also with bundled b56) to IDE and start (keep directory deployment checked)
** create a new project CustomerCMP
** open Ear project with required projects (war, ejb and app-client)
** build the ear project
** "undeploy & deploy" the project
** in Services/ enterprise applications / app node select action "undploy"
verify the ear node is removed
** in Projects: "Run" the CustomerCMP porject

in the out-put: build.xml (run) will see the exception described above.

** in Services the ear node is deployed.
** with a firefox browser: can access to the application

http://localhost:8080/customer/index.html

can get the create customer form.

If the Directroy Deployement is unchecked (disabled) there is no issue.
