RE: Cannot allocate servlet instance for path

[Annam, Sunil]

Found the problem. I am using Windows NT. In NT explorer, "Web-inf" and "WEB-INF" are 
both displayed as "Web-inf". Only if you right click and see property you can find 
MS-DOS name which is the actual one.
When I installed Tomcat, "examples" webapps had a folder "Web-inf" which is actually 
"WEB-INF". So I also created same name.

Spent almost a day but now I am happy that it is working.

Subject: Cannot allocate servlet instance for path


Hi,

I was using Tomcat 3.x and now switched to tomcat 4.1.9. I am not able to run the 
servlets that I used to do. So just for testing I did the following
created a folder "exmp" under webapps. created a foler "Web-inf" under "exmp" and 
"classes" under "Web-inf". Copied "HelloWorldExample.class" from 
webapps/examples/Web-inf/classes. 

webapps-->exmp
                    |->Web-inf
                            |->web.xml
                            |->classes
                                   |->HelloWorldExample.class


Modified server.xml. Added the following
<Context path="/exmp" docBase="exmp" debug="0"
                 reloadable="true" crossContext="true">
        </Context>

Created web.xml in Web-inf

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
     PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd";>
<web-app>

    <servlet>
        <servlet-name>HelloWorld</servlet-name>
        <servlet-class>
          HelloWorldExample
        </servlet-class>
        
    </servlet>


  </web-app>


When I start Tomcat and try to access HelloWorldExample by url 
"http://localhost:8080/exmp/servlets/HelloWorldExample";, it gives me Error 404
In the localhost_log.txt
invoker: Cannot allocate servlet instance for path /exmp/servlet/HelloWorldExample
javax.servlet.ServletException: Wrapper cannot find servlet class HelloWorldExample or 
a class it depends on
        at 
org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:880)


Any idea what is happening ? what am I missing ?

HelloWorldExample from examples/servlet/HelloWorldExample is working.

Thanks in advance.
