132 WebSphere and .NET Coexistence
If you have to inter-operate with an existing chatty service interface, consider
using a façade in the service process. This is illustrated in Figure 4-2 on
page 114.
If you have to interact with an existing chatty client, consider using a façade in
the client process. This is illustrated in Figure 4-3 on page 115.
Stateless interfaces can be chatty; do not assume that they are not (see
Figure 4-10 on page 127).
Consider using asynchronous techniques to reduce call blocking so as to
improve invocation responsiveness.
4.3 Layer interaction classifications
In the previous section, we identified several possible interaction classifications
between an application deployed in WebSphere and an application
