Hi, Your observation is correct. But I was trying to seek a way without unmarshalling and re-marshalling as the xml would deal with thousands of method call inputs. Unmarshaling such huge data and filling the list could put memory constraints.
My scenario is as follows: I have some 6 methods that could be called n number of times in any order at any point of time in a day. I have to marshal the inputs from the method called onto the xml. Suppose that method 1 is called in the start of the day and it's object has been already marshaled into xml. By overwriting what I meant was that when method 2 is called later, simply marshal(method2 object) would result in loss of method 1 's data in the xml as castor is making a fresh write of method 2's object onto the xml. Hence I wanted to know if I could simply append method 2's object without disturbing the already written method 1 object. (mapping.xml covers mapping for all the methods) Please let me know if this is still not clear. Thanks in advance.
