如何从Eclipse中的参考库导入类？

Question

I am new to both Java and to the Eclipse IDE, and I am having trouble with adding a Referenced Library and actually using it in my code.

I am in a software testing class, and my assignment is to use the JWebUnit library to run some basic tests on a website of my choice. I have downloaded a zip of the library and added it to the build path, so that it shows up in my Referenced Libraries list.

When I try to actually use that library, though, the import statement gives an error.

I just cannot figure out what I am doing wrong that the base class cannot see this library.

The screenshot show that you have added the folder net as class folder to the Java Build Path . Maybe you have added the source code ( .java files) or Javadoc ( .html files) instead of the executable bytecode ( .class files). Usually .jar files are provided containing .class files which can directly be added to the Java Build Path .

Probably you want to download eg the file jwebunit-3.3-release.zip from here and add all JARs contained in that ZIP (in the root folder and in lib ) to your Java Build Path instead.
