Eclipse still giving me red squiggly lines after I add the libraries to the classpath

I got the libraries that I needed to be recognized by the javac task, but my Eclipse IDE still doesn't "get it" lol. When I go to Preferences menu, what do I need to point to the library folders to make the re开发者_JAVA技巧d squiggly lines go away? :)

Thanks, Alex

How did you "link" the libraries? I do from Project properties (right click on the project, "Properties", then "Java Build Path")...

You need to go to the project's properties and specifically to Java Build Path. Then add your libraries to the Libraries tab.
