Well, the indexOutOfBoundsException can't possibly be thrown by the method add of an ArrayList (that's the type of productArrayList, isn't it?). In fact there's nothing in your snippets that'll throw that exception. Did you debug the method call on the server side ? Somewhere in your Eclipse or HostedMode console you'll have a complete stack trace that'll tell you the exact line of code that's throwing that exception. I suggest you read it carefully.
As for the lifecycle of your RPCs, it is the normal lifecycle of a servlet.
