Question

public void test(Object obj){

       //Here i have to set the values of the obj using its setter . 
    }

Test can be invoked with two objects as parameter. EG: test(standalone) and test(webapp), where standalone and webapp are beans.

public class standalone{
      int version;
   //setter and getter
}

public class Webapp{
     String version;
   //setter and getter
}

This test method has to set the values accordin to the parameter object.
Eg: IF i pass standalone as param. standalone’s setter method shd be called. How to achieve this?

Note : Without using interface. How to do this?
Thanks.

public static void setVersion(Object obj, int v) throws Exception {
  for (Method m : obj.getClass().getMethods()) {
    final Class<?>[] t = m.getParameterTypes();
    if (m.getName().equals("setVersion") && t.length == 1)
      m.invoke(obj, t[0] == String.class? String.valueOf(v) : v);
      break;
  }
}
