For various good reasons, Eclipse doesn't work with your system
CLASSPATH. You must put the JAR into your project as a JAR/library.
There are lots of ways to do this.
You can do it "physically". This is not the best way, but it works very
well. It means a copy of that JAR in every project.
The most popular (and best) way is to put a dependency in your pom.xml
file for that JAR. That way, every project gets it out of your
..m2/repository each time you build. Of course, you have to grok Maven to
do that.
Hope this helps.

Well, you think about it. Does the JAR have to be there for the project
to work/run/etc.?
Maven is a steep learning curve, however, I think Eclipse has made it
easier. Maven copies the JAR physically into the project when it builds
it so you don't have to manage any JARs directly.
Otherwise, you can just do what we all used to do years ago before
Maven: stick the JAR under a subdirectory named lib and use Build Path
to add it to the project.
Sorry.
