Java - Run multiple packages program

Question

I am trying to build a MakeFile for a java client/server programme.

I have a path like this:

• src
  • Server
    • CServer.java
  • Client
    • CClient.java
  • Shared
    • SharedClass.java

Both client and server use Shared package like this:

import Shared.SharedClass;
...
  SharedClass mysharedobject = (SharedClass)UnicastRemoteObject.exportObject(anobject, 0);

My makefile is quite simple

all: compile test

compile :
    mkdir -p bin
    javac -d bin src/**/*.java

test:
    java -classpath bin Server.CServer &
    java -classpath bin Client.CClient &

but i receive a ClassNotFoundException: Shared.SharedClass when running server.

It works when all java files are in the same package, but i would like to divide it.

Is there a way either to compile all in the same folder or run properly class files in differents folders.

Edit: I have the same error trying to run a built jar

This is not right:

javac -d bin src/**/*.java

make always runs /bin/sh , and /bin/sh is a POSIX shell. POSIX does not define "enhanced" globbing like ** to search all subdirectories. If you add this to your recipe:

ls src/**/*.java

you'll see a list of files that are being compiled. If you need to search multiple subdirectories you'll have to use find , such as:

javac -d bin $$(find src -name \*.java)
