How to add multi jar path in java

Question

I want to have run java -cp with several jars

How I can do it ? for example in myProject I have two different jar's : 1.jar a relevant class myClassA 2.jar b myClassB The mainclass is myMainClass.java

I tried on windows from cmd:

 java -cp c:/myproject/a.jar myClassA,c:/myproject/b.jar myClassB

But it didn't work , I tried also ;

java -cp c:/myproject/a.jar myClassA;c:/myproject/b.jar myClassB

but it didn't work also Did I miss something ?

The `-cp` part only lists jars where the classes will be found and it is not the right place to specify class names , try something like `java -cp c:/myproject/a.jar;c:/myproject/b.jar myMainClass` — Arnaud, Oct 26 '17 at 07:56
If you need to execute it in Unix environment, use `:` to separate the jar files instead. — Alex, Oct 26 '17 at 08:02
@user1365697 I just provide more information only, in case someone would like to execute in Unix — Alex, Oct 26 '17 at 08:04

This will create a .class file

javac -classpath "[jarname with specified path;jarname1 with specified path]" [java filename]

To execute the class file

java -cp [jarname with specified path;jarname1 with specified path]: [java filename]

does in my case it should be : java -cp [c:/myproject/a.jar myClassA,c:/myproject/b.jar myClassB] :myMainClass – user1365697 Oct 26 '17 at 08:21
