雄猫 在Eclipse中工作，但在部署时不工作

Question

I have a project on tomcat that works well when I run it "on server" via Eclipse. However, when I exported the WAR file and deployed it, the servlets don't work. Only my JSP pages work. Here's part of the web XML:

<display-name>CandC3</display-name>

Then, the <welcome-file-list> section and then servlets and mappings. Here's one:

  <servlet>
    <description></description>
    <display-name>LoginServlet</display-name>
    <servlet-name>LoginServlet</servlet-name>
    <servlet-class>candc3.LoginServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>LoginServlet</servlet-name>
    <url-pattern>/LoginServlet</url-pattern>
  </servlet-mapping>

Now, when I try to access this servlet as someserver:8080/CandC3/LoginServlet?param1=val1 I get an error 404: Servlet LoginServlet is not available

Any ideas? Am I missing something obvious? Shouldn't an export from eclipse work seamlessly in a server ;)

More info: catalina.out

INFO: Deploying web application archive CandC3.war

Also, after I restart tomcat, the first time I try to use the Servlet I get:

javax.servlet.ServletException: Wrapper cannot find servlet class candc3.LoginServlet or a class it depends on

and as the root cause:

java.lang.ClassNotFoundException: candc3.LoginServlet

After that, on subsequent tries I get error 404: Servlet LoginServlet is not available

Answer 1

Do you have a web application under your tomcat/webapps directory named CandC3? Does it have a directory under it named WEB-INF with a "classes" directory or similar under it? Otherwise, can you physically locate your servlet class candc3.LoginServlet at all anywhere under the CandC3 directory?
