Is there a way to specify the String name of a property in a particular bean and return the class that the getter corresponds to?

You can use the java.beans.Introspector class to obtain information about a given bean. You can't query the BeanInfo for a specific property, but you can loop through them:
private Class<?> getPropertyType(Class<?> clazz, String property) {
BeanInfo beanInfo = Introspector.getBeanInfo(clazz);
PropertyDescriptor[] propDescriptors = beanInfo.getPropertyDescriptors();
for (PropertyDescriptor propDescriptor : propDescriptors) {
// String name of a property
if (property.equals(propDescriptor.getName())) {
// Class the getter corresponds to.
return propDescriptor.getPropertyType();
}
}
...
}

Do you know if BeanUtil can do this?

I guess so, but you probably ought to state that you're using Apache Commons before you ask the question!
Found it... org.apache.commons.beanutils.PropertyUtils.getPropertyType(Object bean, String name)
