    Unhappy Referencing libraries in java

    I have a project folder, under which I have a package named programs.

    Suppose I have a jar file named vivir.jar that contains files that I need to use in some class in my programs package.

    I created a folder, lib, in the project folder and copied vivr.jar to lib. Then I built a path to it. Now I have a referenced libraries folder that contains vivir.jar and it's package and classes.

    Suppose I have a yutu class in vivir.jar that I want to use in some class located in my programs package, whenever I create a yutu object, I get an error saying that the object can not be resolved to type. So basically I cannot use classes in the jar file that's located in the referenced libraries.

    I'm I missing something? Do I need to import the package in vivir.jar in order to use the classes within it? Any help is appreciated.

    Thanks

    What tool (IDE, programmer's editor, etc.) are you using to write your source code? What OS are you using?

    If the .jar file was on your CLASSPATH, you shouldn't have to do anything else to use its contents in your project, but there are other ways to accomplish the same thing that depend on your answers to the questions I've asked.

    Solved the problem.
    I had to create a class in the (default package) that came with the jar file. All's well
