14.3 Development guidelines

To test the Extended Enterprise Web services patterns presented in this chapter, we simply introduced the firewalls and a simulated Internet between the source and target application scenarios from:

• Chapter 8, "Using RPC style Web services" on page 147

• Chapter 9, "Using document style Web services" on page 183

• Chapter 10, "Using the Web Services Gateway" on page 215

Our target application Web services and our source application Web service clients were unchanged. We just modified the end point DNS entries where needed and opened the required firewall ports. You could also update the end-point SOAP address location in the client WSDL, then redeploy the client application to WebSphere, selecting the Deploy WebServices option (see Figure 8-14 on page 172).

When using the Web Services Gateway between the source and target applications, that gateway service can be redeployed to use an external Web service provider with no change required to the source application. See 10.4.2, "Deploying the Web Services Gateway service" on page 224

See Appendix A, "Scenarios lab environment" on page 329 for a description of our lab environment.
