A jar file is just a compressed zip file with a content that may make it suitable to be executed as a java program or library. In general you can uncompress it with general zip tools. In general if it is a program (containing an executable class file) you could do something like java -jar filename.jar org.something.package.Classname to execute the program if it contains a library then nothing is executable like that, but it has to reside in a classpath. Java classpaths that contain jars must usually be explicitly mentioned, ie. a classpath would explicitly contain the .jar, and not just its containing directory. There are tools like Ant that automate this process somewhat with things you could call project build files. Maven is another one, and the third popular one is called Gradle I believe. Normally you can use a zip tool to see the contents of the file, so perhaps the "Ark" program would also be able to open it. Regards. Thomas Taylor schreef op 06-12-2015 16:15:
How does one open and use a *.jar file?
Thanks, Tom KG7CFC
