I showed you how to create a batch file for compiling your servlet. The batch file that I provided includes these jar files on the classpath. This hasthe effect of making the following packages, among others, available to your compiler. This is a requirement for writing and compiling servlets and JSP.

  • javax.servlet
  • javax.servlet.http
  • javax.servlet.jsp

You should make certain that you can successfully compile, deploy, and access the sample servlet that I provided in Java4308 before continuing with this module.

Discussion and sample code

Before leaving this module, lets make absolutely certain that everything is working by creating, compiling, deploying, and accessing two servlets and one JSP.

Using what you learned in Java4308 , create compile and deploy the two servlets shown in Listing 1 and Listing 2 . Then create and deploy the JSP shown in Listing 3 .

Start your server and point your browser to http://localhost:8080/Inew2338_050 in order to see Figure 2 in your browser.

Figure 2 - Inew2338_050.java.

Point your browser to http://localhost:8080/Inew2338_051 in order to see Figure 3 in your browser.

Point your browser to http://localhost:8080/Inew2338_052.jsp in order to see Figure 4 in your browser.

What's next?

If those tests were successful, your system is ready for you to move on to the next module and begin learning the programming details required to create Java servlets.
