In this chapter, we discussed a simple binding scenario by which we can make an EJB service accessible across the firewall to the outside world. If you have an Apache SOAP implementation with you, you can also try out the samples and see the results. Similar to what we did in this sample, at times we need to tunnel or redirect services through intermediaries either due to protocol or format mismatches or due to some other reasons.

All these activities are concerns apart from your business logic coding and need to be addressed at your application framework-level. In this chapter too, we have performed it in the same manner, but we have done a lot of steps to configure the web server with Apache SOAP. Later, when you go through the JBI and ESB samples you will realize that the same functionality can be achieved by selecting and configuring suitable JBI components.

ESB implementations like ServiceMix make use of new generation SOAP frameworks which bind binary services such as EJB and...
