title: How to call methods that is in an external library?
body: <p>I have already linked the necessary jar file to the project that I'm building right now. But when I tried to call methods supported by that .jar library, Eclipse told me that "this method can't be resolved". Now what should I do? </p>
  
  <p>Is there any syntax, such as "import xxx.jar;" that I have to add to the source to make it work?</p>
  
  <p>Again, sorry I am sort of new to java. I could easily do that on linux with a tag but can't see how to accomplish the same thing with eclipse. I know it is confusing without pictures but I'm not allowed to post any since I just registered.</p>
