SpringBoot custom 404 page with embedded tomcat out of spring boot context path

I have a spring boot embedded tomcat(spring boot v2.4) application with this context path (server.servlet.context-path=/store). now when I go to this address (https://localhost:8080/sto), the 404 Tomcat page is displayed. how can I customize this 404 page Tomcat? I use jsp and war packaging. to do this, I created a project in the simplest possible way and configured it according to this document https://docs.spring.io/spring-boot/docs/current/reference/html/features.html#features.developing-web-applications.spring-mvc.error-handling.error-pages-without-spring-mvc

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>

@Bean
public ErrorPageRegistrar errorPageRegistrar() {
    return this::registerErrorPages;
}

private void registerErrorPages(ErrorPageRegistry registry) {
    registry.addErrorPages(new ErrorPage(HttpStatus.NOT_FOUND,"/error.jsp"));
}

and I put an error.jsp in the webapp folder, But it does not work. is this the right way?

Tomcat configures error pages on a per-context basis. You've mapped the context to /store so the error pages will only take effect for errors that occur when handling requests to /store/*.

Rather than configuring the entire context's path, you may want to consider changing the dispatcher servlet's path using spring.mvc.servlet.path instead.
