the site suggests

In the directory war/, create a file named guestbook.jsp

and i think you have named the file as Guestbook.jsp .

WARNING: Nested in javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/jsp/guestbook_jsp (wrong name: org/apache/jsp/Guestbook_jsp):
java.lang.NoClassDefFoundError: org/apache/jsp/guestbook_jsp (wrong name: org/apache/jsp/Guestbook_jsp)

please check that and try again.

also welcome to JavaRanch

Yes, case counts!

Also, please be sure to take the time to compose descriptive subjects for your posts; read this for more information.

A title such as "JSP error" is not helpful. What would happen if all posts had such a title?

Please go back and change your post to add a more meaningful subject by clicking the button on your post.

wrong name: org/apache/jsp/Guestbook_jsp

You should be able to find this error for normal classes as well. Try compiling a class with a capital letter for the first one and then run it with a wrong name like it suggests in the error.

I know this thread is abit old but I just found the solution to this problem so I might as well just share it :)

Navigate to your <tomcat folder>\work\Catalina\localhost\<Web application name>\org\apache\jsp folder and delete away all the .class and .java files (these files are auto-generated when you run your jsp pages in the browser).

The location of <tomcat folder> depends on where you install it. For me, I did not install it but made use of a zipped version instead, hence it is rather straight forward - it is the folder which I unzipped.

The <Web application name> is the one in <tomcat folder>/webapps folder where all your jsp files are.
