I know this question has been asked many many times but I can not seem to find a solution.

I am receiving this error message: “The requested resource (/package/servlet/access) is not available.”

I have this web.xml file:

The java file which is not being found is located in the Package.Servlets package in the sources folder in netbeans.

I am new to Tomcat Environment and would like to know needs to be done. I tried to check for usages from that class, but none could be found. Therefore I am assuming this is related to the web.xml settings.

EDIT: I have also checked the logs, there doesn’t seem to be any exceptions being raised.

    The problem with the web.xml file that you provided is that there are no <servlet>s and <servlet-mapping>s defined. Tomcat needs all the servlets in your application defined in the web.xml file, plus the mappings in order to know which servlet to call when you open a URL.

    You can see an example of this in the webapps/examples/WEB-INF/web.xml file in your tomcat installation
