There is almost no difference between handling request bodies and handling response bodies. There are two cases to consider:

1. Adding a body to a new adapted request is essentially the same as adding a body to a new adapted response. After creating a new request using Host::newRequest() and before calling host::xaction::useAdapted(), you need to call Message::addBody() method to add an [empty] body to the newly created request message. Then you do exactly what the code mentioned in #2 below does.

2. Adapting an existing request body is essentially the same as adapting an existing response body. Several published adapters adapt existing message bodies so you have examples to look at. To start with, look for the sample code that calls host::Xaction::noteAbContentAvailable() and handles adapter::xaction::abContent*() calls from the host application.

Can you help with this problem?
