Spring Packaging for Deployment

The modular aspect of Spring extends to deployment as well, because you can deploy your application with only the subset of Spring JAR files you need (for example, spring-jdbc.jar). Table 6.1 shows how Spring provides the packages using various JAR files. Notice how the spring.jar is bigger than others, because it is the complete package. I tend to include the complete spring.jar file in my applications because 1.7MB isn't considered very large these days, especially for server-side applications.
