I'm using IBM Websphere Integration Developer (pretty much same as RAD the way I'm using it) to generate a top down Java skeleton from WSDL. It generated a lot of classes. My question is, what are all these generated classes used for? There are ser/deser classes, helper classes, and others. Some seem to be business objects that were derived from the WSDL and XSDs. I tried very hard to find documentation on what all of these generated classes are used for but I couldn't find anything. Can anyone give me a breakdown of what these different generated classes are and what they are used for.
