HTTP Status 500 Error

Hello everyone,

I have been studying core JavaServer Faces recently. After I test the sample application of number quiz in chapter 2, I always get the HTTP Status 500 error. Its description is:The server encountered an internal error () that prevented it from fulfilling this request.

The directory structure I use is the same as Figure 2-5 in page 47. After that, I compile the two .java files(ProblemBean.java & QuizBean.java) and place the generated .class files into the WEB-INF/classes/com/corejsf directory. I also add a directory named lib, which parent is WEB-INF. In the lib directory, six needed jar files are included(referenced in page 11).

After I put the whole application in the Tomcat's webapps directory and start it, I input "http://localhost:8080/numberquiz"in the browser and get the above error. I am eager to know the reason because I think I have done exactly accorging to what the book had instructed and correct two errors in the faces-config.xml(change index.faces to index.jsp). By the way, Tomcat version I use is 5.0.28, JSF is 1.0 and browser is IE6.0. After I had been looking the Internet all the afternoon, I finally find the solution to it. In the web.xml, I should add the following tags:

But I still don't know why I must do this. Please give me some advice!

Thanks in advance!

Hi Richard,

I am sorry for missing that. But you can download the free chapter of this book in this site. The six needed jar files are jsf/lib/jsf-api.jar, jsf/lib/jsf-impl.jar, tomcat/server/lib/commons-digester.jar,
tomcat/server/lib/commons-beanutils.jar, tomcat/webapps/jsp-examples/WEB-INF/lib/jstl.jar, tomcat/webapps/jsp-examples/WEB-INF/lib/standard.jar.

Here the version of Tomcat must be 5.0.X, NOT 5.5.X and the JSF implementation version is 1.0 or 1.1.
Someone said when we use Myfaces package for MyEclipse to create a JSF project, there will be no error because this utility had added the listener tag in the web.xml.

Regards,
Ailsa
