Eclipse error … cannot be resolved to a type

Question

I have a dynamic web project that I am working on to migrate a jsp/servlet app from JRun to Tomcat.

I am getting the error: com.ibm.ivj.eab.dab.DatastoreJDBC<

Answer 1

I was importing the source into the wrong folder. I'm so used to using Visual Studio, that I expect all IDE's to be so accommodating.

Answer 2

I just closed all the files and reopened them, and voila!!! Hope this helps someone in the future ;)

Project -> Build Path -> Configure Build Path
Select Java Build path on the left menu, and select "Source"
 click on Excluded and then Include(All) and then click OK
    Cause : The issue might because u might have deleted the CLASS files 
 or dependencies on the project

Also, "have you tried turning it off and back on again"? (Restart Eclipse).
