If you face an error like "There are no resources that can be added or removed from the server", then

1) Go to the META_INF of your websvcsEAR and go to the application.xml.
2) Goto modules-> clickDetails and add the module that is existing. i.e., some EAR which your project demands.
3) Click ok
4) Now go to your server -> right click -> add and remove -> add your EAR.

Answer 5

The reason why this is happening is because eclipse by default looks for the deployment descriptor in the folder {project.home}/Webcontent/WEB-INF/web.xml where as the Maven puts them in src/main/webapp/WEB-INF/web.xml.

So when you are trying to add your project onto the server eclipse cannot find a deployment descriptor and hence you get the annoying message.

This can be solved by adding the following entries in .settings/org.eclipse.wst.common which can be found in

1. Project home folder in your workspace if it is a new maven project.
2. The folder where you already imported from if you are using Import -> Maven projects.

Make the following changes in to the org.eclipse.wst.common

1. wb-resource deploy-path="/" source-path="/src/main/webapp"/. Add this entry.
2. Edit --> property name="java-output-path"

Please check the following link from more details. http://java.dzone.com/articles/webapps-eclipse-and-maven. The comments section has an excellent example with a working project.

You need the project to have a Eclipse Dynamic Web Module facet. You can try doing this via the project properties dialog and looking at project facets, then clicking the appropriate check box. This may not be available however, so you may need to do the next thing.

Create a backup of your project and follow the directions at dzone.com. This'll allow you to modify the project facets via your eclipse .project file.

Keep in mind, once you add those facets, you cannot change them back via Eclipse. Definitely make sure you have a backup before starting.
