HTTP Status 500 Error

[Ailsa Cape]

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:

 
  <listener>
    <listener-class>com.sun.faces.config.ConfigureListener</listener-class>
  </listener>

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

Thanks in advance!

. In the lib directory, six needed jar files are included(referenced in page 11).

for those of us that dont have that book, can you please list down the six jar files?

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.
