Whenever I compile the Code on Tomcat 4 I get the error
PARSE error at line 6 column 39
org.xml.sax.SAXParseException: Element type "web-app" must be declared.
My Project is a simple CRUD operation on Student DB using Spring RESTful Webservices. The pom.xml define dependencies on spring framework 5, tomcat 9 and mysql 8.
I have googled the reason behind this and mostly come across explanation that says When the order of servlet, servlet-mapping, welcome-file-list is not maintained the web-app declaration error is thrown.But that is not the scenario here.Can anyone explain What I am missing?
You haven't shared enough information. Pom is important and you use Tomcat 4 of 2006. Are you serious? The below example works, so compare and fix http://websystique.com/springmvc/spring-4-mvc-helloworld-tutorial-full-example/
web-app is part of j2ee
EDIT: As you added more info - pom. I see no issue with it.
I did update a bit though - my endpoint are / and /something...so url-pattern is not /* for me...it is /
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param> <param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
Please start a brand new app and build step by step
Note: Check if you can clean your repo...may be issue with a dependency
