Failed while installing JavaServer Faces 2.0.
org.osgi.service.prefs.BackingStoreException: Resource '/projectName/.settings' does not exist.
Don't give up hope. As you do not have the option to use a better IDE you can still edit the files by hand.
open the file : "org.eclipse.wst.common.project.facet.core.xml" located in the .settings directory and add:
<installed facet="jst.jsf" version="2.0"> </installed>That should do the trick
