I have a static method which has the following signature.

public static List createBeanCollection(){
}

I can't chage this, now this is the problem. how can i pass it
parameters
so in the method i can use them and return a dinamic list of objects,
i'm using ibatis
for test purposes i did the following.

<code>
public static List createBeanCollection(){
   MiBean m = new MiBean();
   m.setNombre("prueba");
   List beans = new ArrayList();
   beans.add(m);
   return beans;

}
</code>

ok, it works fine, but now i want to replace the list i created by
hand with an
object that makes a query over a db, so the code would be this.
<code>
public static List createBeanCollection(){
   List beans = miDao.onbtenObjetosPorId(valor);//dao that retrives
object from a db.
   return beans;
}
</code>
but i cant use the "valor" parameter, due is not possible to use a no
static-variable
in a static method. at the moment i've resolved it in this way

<code>
public static int valor;//the variable was declared as static.

public static List createBeanCollection(){
   List beans = miDao.onbtenObjetosPorId(valor);//i can use it now
   return beans;
}
</code>
however this solution is not the best, because i'm expossing the
properties of my class
hope you can help me with this little problem, just remember i can't
change the method
signature.

Thank you in advance.


If you need to pass something in, you should make sure its thread safe.
  One way to do that is have a ThreadLocal with your parameters.
