Perhaps your project lacks in some necessary jars. Try this:

• Right click your project>>build path>>select libraries>>add jars to add necessary jars in your project.

• Go to your project's Properties，set the project facets. make the 'java' option to match your Java Compiler compliance level,such as '1.6'.
