How to use external jar files in java

gssbvirgo

Now looking at struts, you need to use the struts.jar file. But when using import, you cannot import struts.jar and check some information on the Internet. It says that you only need to copy the jar file to the classpath. I did but Not yet. May I ask your comrades for suggestions?

Also: I didn't use ide, just compiled under cmd.
