Introduction

Before you can write effective OFBiz Java code, you need to understand some basics about the environment in which OFBiz operates. In the previous chapter, we learned that OFBiz executes within a JVM. That JVM, in turn, hosts a Java servlet container. The servlet container provides all the basic programming infrastructure necessary to build and run OFBiz web applications (sometimes referred to as "webapps").
