Answer 1

Adding the commons-logging jar into the "lib" folder,worked for me.

Here's the download link: https://commons.apache.org/proper/commons-logging/download_logging.cgi

Hope this helps

Answer 2

Tried all sorts, but what worked from me was removing all references to javax from the the POM; deleting javax jars from Maven repository and then re-adding back to the POM. I think one of the jars was corrupt.

Answer 3

verify web.xml.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="WebApp_ID" version="3.0">
    <display-name>Admin</display-name>
    <servlet>
        <servlet-name>ServletName</servlet-name>
        <servlet-class>ServletName</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>AdminServletNameServlet</servlet-name>
        <url-pattern>/ServletUrl</url-pattern>
    </servlet-mapping>

</web-app>

Answer 4

web.xml is the culprit. I had 2 controllers mapped to the same URL pattern. And this was creating issue. Server started as soon as I changed the URL pattern mapping of one of the controllers.

Answer 5

Just check web.xml, any changes in servlet mapping will result in that kind of problem. try running another application which is perfect, while doing that make sure tomcat in server console is empty(no drop down if their delete it) then run

Answer 6

Just check your web.xml for any typo.

Or verify whether your servlet-name node in web.xml and @WebServlet("/abc") in servlet are same.

I fix this issue by above change,

Answer 7

You need to add the following jar files to your web-inf/lib folder, also you need to configure build path -- Right click your project--Build path -- configure build path -- libraries -- add external jars (add all the below jar files). And restart server
