JNDI lookup failed for the resource Type: javax.sql.DataSource

Question

The error is in the title. It's very strange, because I was doing some modifications to the xhtml code and its beans, turning the glassfish server on and off and on again several times, and suddenly this error appeared. I did not touch the web.xml or any of those types of files while I was working, just the xhtml and its beans.

Error message:

In my case I removed the eclipse jar file in netbeans. Click the eclipse jar file under libraries and click remove. Then Right on Libraries, choose add Jar and provide the location of the Eclipse jar file.

After try deploy you project it shall work
