Hey everyone.
I have setup tomcat 4.0b1 and have it working fine for a very simple
servlet. Just prints a string to the web browser. As soon as I try and
introduce a parent class (that will handle some initialization) for all my
servlets, tomcat blows up.
I get this error: "java.lang.NoClassDefFoundError:
javax/servlet/http/HttpServlet" along with a stack trace. I don't
understand at all. Does tomcat expect the servlets to extend "HttpServlet"
directly instead of being a subclass of a class that extends "HttpServlet"?
In the code below case "A" works and "B" does not. Ideas? Suggestions?
Thanks,
-james
case A:
----------------------------------------------
public TestServlet extends HttpServlet
{
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("testing");
}
}
----------------------------------------------
case B:
----------------------------------------------
public SpecialHttpServlet extends HttpServlet
{
public void init()
throws ServletException
{
// do some initialization stuff
}
}
public TestServlet extends SpecialHttpServlet
{
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("testing");
}
}
