Getting error when loading servlet

[Paul Mackellar]

I have downloaded tomcat 6 and am running through a book which tells me to create a new project "ch1" with the classes and web-inf folders. I am trying to visit the servlet using localhost/ch1/Serv1 but keep getting the following error

  HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

<servlet>
	<servlet-name>Chapter1 Servlet</servlet-name>
	<servlet-class>Ch1Servlet</servlet-class>
</servlet>

<servlet-mapping>
	<servlet-name>Chapter1 Servlet</servlet-name>
	<url-pattern>/Serv1</url-pattern>
</servlet-mapping>
</web-app>  

can anyone help me to get this working?

Thanks

Place your servlet in a package other than the default.

As this is not Tomcat-specific, moved to the Servlets forum.

[Paul Mackellar]

I don't quite see what you mean.

My directory structure is tomcat>webapps> "ch1"which contains> classes and web-inf.

What should i do?

[Bear Bibeault]

You're doing quite a few things wrong.

Firstly, it's WEB-INF, not web-inf. Case counts.

Secondly, the classes folder belongs in WEB-INF.

Thirdly, all classes in a web application must be in a package other than the default. If you are not familiar with Java packages, that's your first step.
