The servlet classes that are provided with the IBM Toolbox for Java work with the classes in the com.ibm.as400.access package to give you access to information located on the system. You decide how to use the servlet classes to assist you with your own servlet projects.
A typical scenario is this: A web browser connects to the web server that is running the servlet. The jt400Servlet.jar and jt400Access.jar files reside on the web server because the servlet classes use some of the access classes to retrieve the data, and some of the HTML classes to present the data. The web server is connected to the IBM i system where the data is stored.
Note: The jt400Servlet.jar file includes both the HTML and Servlet classes. You must update your CLASSPATH to point to the jt400Servlet.jar file if you want to use the classes in the com.ibm.as400.util.servlet package.
