Java compiler level does not match the version of the installed Java project facet.SSJ UnknownFaceted Project Problem (Java Version Mismatch)
I made a simple Java Google AppEngine application called Guestbook in Eclipse 3.7 and am trying to run it. However, I am encountering an error that lacks a quick fix:
I tried navigating to Project | Properties to change my project facet. However, I could not find a setting that dealt with "facet."
What does "installed Java project facet" mean, and how do I fix this?
You can see your facets via Right click on your project->properties->Project Facets,
I think your Java facet does not match with the installed one. I'm suspicious that facet is at version 1.5. Please check it.
Add-on:Open the Navigator view, expand the .settings folder, open the file org.eclipse.wst.common.project.facet.core.xml and manually set the Java version to 1.6.
