Tomcat config

Remove `javax.servlet:javax.servlet-api:4.0.1` from the `WEB-INF/lib` folder. The Servlet API is supplied by Tomcat, so having that file is the webapps local classpath causes conflict. --- Don't know what you did to get it there, it wasn't added by Maven, as can be seen by the lack of the `Maven:` prefix. Don't know why you did it, given that it is already in your classpath as "provided". — Andreas, Sep 16 '20 at 19:18

**Tomcat 10** is for Servlet 5.0, which **is not backwards compatible**, given that all the Java types were moved from package `javax.servlet` to package `jakarta.servlet`. Don't use beta version of Tomcat 10, **use Tomcat 9**. — Andreas, Sep 16 '20 at 19:30
@Andreas thanks for your advice. I didn't know that. I will let you know whether it's successful or not. — vikalp rusia, Sep 16 '20 at 19:35
See [Migrating from 9.0.x to 10.0.x](http://tomcat.apache.org/migration-10.html) — Andreas, Sep 16 '20 at 19:37

Tomcat 10 is for Servlet 5.0, which is not backwards compatible with earlier versions of the Servlet specification.

That is because all the Java types were moved from package javax.servlet to package jakarta.servlet.

Don't use Tomcat 10, use Tomcat 9.

If you want to upgrade to Tomcat 10 or later, see Apache Tomcat® - Migration Guide - Tomcat 10.0.x.

See Spring Framework issue #25354 (Support for Jakarta EE 9 (annotations and interfaces in jakarta. namespace))* for status of Spring support for Servlet 5.0 / Tomcat 10.
