    jep.setValue("arg", obj);
    jep.eval("x = somePyModule.foo1(arg)");
    Object result1 = jep.getValue("x");

    // using getValue(String) to invoke methods
    Object result2 = jep.getValue("somePyModule.foo2()");

    // using invoke to invoke methods
    Object result3 = jep.invoke("somePyModule.foo3", obj);

   // using runScript
   jep.runScript("path/To/Script");
