Include all the jars in a directory within the Java classpath

Question

how can we include all the jar files within a directory in the same classpath?

My attempt:  java -classpath lib/*.jar:. my.pack.Code1 and it is not able to find class files that are certainly in those jars. Do we need to add each jar file to the classpath separately one by one?

Answer 1

Windows:
java -cp ppp.jar;dir/* my.app.ClassName

Linux:
java -cp ppp.jar:dir/* my.app.ClassName

Note: 
- Windows path separator is ";"
- Linux path separator is ":"
- In Windows if cp argument does not contains white space, the "quotes" is optional

Answer 2

Just use lib/*   not lib/*.jar  

That's the syntax 'java' uses.
