Enquire about instance migration

Question

Hi,
I am using Oracle SOA 11g. I already deployed one composite(version 1.0) which has many instances running in different state. Now, i have made some changes in the composite(version 1.1), a minor change in the business flow and i deployed in EM. How can i make all the instances to move into the new composite created ?
Can anyone help me in this.

Mat,
From the Account#.depositeAmount() call it seems like you want to change the class on which the method is to be called. It looks like you need to bring some OPPs into your design. :-)
You'll most probably find this example in most of the books but I'll give it anyways.... ;-)
Make an abstract class called AbstractAccount haveing your abstract method depositAmount(double amount), then make all your Account classes extend from this class like SavingsAccount and CheckingAccount etc. and give the implementation of your specefic methods in them.
NOW do this
AcstractAccount accounts[] = new AbstractAccount[2];
accounts[0] = new SavingsAccount();
accounts[1] = new CheckingAccount();
accounts[0].depositAmount(1000);
accounts[1].depositAmount(1000);now as all methods in java are implicitly virtual; the method of the class who's instance is at that location will be called. You could also do that with an ArrayList or Vector if you dont want to use simple arrays.
Hope this helps
