Look at the Sun's official documentation: Setting the class path to understand your options.

A quick way would be just to include your JAR(s) after the -cp:

on Windows

java -cp C:\java\MyClasses\myclasses.jar;C:\java\MyClasses\myclassesAnother.jar utility.myapp.Cool

on Linux/Unix

java -cp /opt/thirdparty/myclasses.jar:/opt/thirdparty/myclassesAnother.jar utility.myapp.Cool

You need to set classpath http://download.oracle.com/javase/1.3/docs/tooldocs/win32/classpath.html. E.g., 

java -cp file1.jar;file2.jar yourApp

or if your jar-files are located in directory lib/

java -cp lib/* yourApp

  • I'm not sure that `lib/*.jar` will work -- the link you included says that the right syntax is `lib/*`, which will match all files ending with `.jar` or `.JAR` in that folder. – Gaurav Oct 08 '16 at 22:49

Sorry, I dont know others IDE, but works with me on Eclipse.
Right click on your project, select

Properties/ Java Build Path/ Libraries/ Classpath/ Add External JARs...

Then choose whatever files you need :v

Not to bother with -classpath parameter you could put references to the jar files into the manifest.mf of your application JAR, if it's you application of course.

You have to fill the Class-Path parameter of the manifest file of the JAR. The standard documentation explains that very well.

When running a jar or class file specify classpath option
