                                           java.lang.String property)
                                    throws PropertyException

                               java.lang.String property,
                               java.lang.Object value)
                        throws PropertyException

Sets the value of the specified property of an object. In order to access the property, the method uses the following strategy. We assume the name of the property is "Sample"

1. Search for a method named get\iSample\i
2. Try direct field access on the member \isample\i
3. Try to use map-style access to properties by calling the method get("Sample")

Parameters:

base - Object to invoke the method on

property - Property name

value - Property value Property chains of the form "prop1.prop2" are *not* supported.

Throws:

PropertyException - If no appropriate access method could be found or if the invocation of one of the property access methods failed.
The nested exception describes the error in detail.
