Please note the name of the third bean in the spring example:-"businessObject"

It means this the bean from where you are supposed to access the common pool.

For your case if you need your own client bean you may have it as follows. But in such a case businessObject is not required.:-

  ... properties omitted



  
  



 



Java classes:-
public class ClientOfTheBusinessObject{
     CommonsPoolTargetSource poolTargetSource;
//
  public void methodToAccessCommonPool(){
     //The following line gets the object from the pool.If there is nothing left in the pool then the thread will be blocked.(The blocking can be replaced with an exception by changing the properties of the CommonsPoolTargetSource bean)
     MyBusinessObject mbo = (MyBusinessObject)poolTargetSource.getTarget();
     //Do whatever you want to do with mbo
     //the following line puts the object back to the pool
     poolTargetSource.releaseTarget(mbo);
  }
}
