There are several ways to embed in a server framework:

Use the Network Server

This is the easiest way to provide connectivity to multiple users who are accessing databases from different JVMs. The Network Server provides this kind of connectivity to databases within a single system or over a network.

Purchase another server framework

You can use within many server frameworks, such as IBM WebSphere Application Server.

Write your own framework

's flexibility allows other configurations as well. For example, rather than embedding in a server that communicates with a client that uses JDBC, you can embed within a servlet in a web server that communicates with a browser using HTTP.
