Suppose I have a handle on an object of type , and I'm told by configuration that it has a bean property of type int with the name age. How can I retrieve the getter for this document?

Is there a better way than prepending "get" and capitalizing the "a" in age, and looking for a method of that name via reflection?

Take a look at java.beans.Introspector. This class allows you to get the list of properties on a class.

If you know property name you can call

Method getter = new PropertyDescriptor(propertyName, beanClass).getReadMethod();
