In this chapter, we have discussed a number of the advanced features of Axis2, with examples. In particular, REST and MTOM are very useful in the context of web services. You can use REST as a way of optimizing the wire format of the message and you can use MTOM to send binary data in an efficient manner. Then we discussed creating Axis2 using a custom repository, which may be located locally or remotely. Next, we looked into deploying Axis2 in various application servers. Finally, we discussed how to use Axis2 to invoke services in an asynchronous manner.
Now we have covered most of the necessary concepts and features of Axis2. We have discussed how to use Axis2, both as a server and a client.
In the next chapter (the last chapter of the book), we will discuss how to add quality of services to your web service. Particularly, we will discuss security and reliability and how to use them with code examples.
