java.lang.ClassNotFoundException：org.springframework.web.servlet.support.DefaultFlashMapManager Weblogic 12c

Question

I am using Weblogic 12c and trying to deploy my application on it but I'm facing the following exception:

I'm using Spring version 5.1.0.RELEASE with JSF and primefaces other applications deployed on the server are ok but this time when I wanted to use Spring rest inside my application it happened

In weblogic.xml file I've added the following configuration to make sure it is using my classes:

<wls:prefer-application-packages>
        <wls:package-name>org.springframework</wls:package-name>
        <wls:package-name>org.jboss.logging</wls:package-name>
        <wls:package-name>org.springframework.*</wls:package-name>
        <wls:package-name>com.fasterxml.*</wls:package-name>
        <wls:package-name>com.sun.xml.ws.api.wsdl.parser.*</wls:package-name>           
    </wls:prefer-application-packages>

In web.xml configuration

<servlet>
    <servlet-name>springServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/applicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>springServlet</servlet-name>
    <url-pattern>/service/*</url-pattern>
</servlet-mapping>

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
</servlet-mapping>

and the applicationContext file like:

<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:aop="http://www.springframework.org/schema/aop"
   xmlns:context="http://www.springframework.org/schema/context"
   xmlns:mvc="http://www.springframework.org/schema/mvc"
   xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
                http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
                http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">

<context:annotation-config />
<mvc:annotation-driven />

<context:component-scan base-package="com.package" />

<context:property-placeholder location="classpath:application.properties" />

the application is working fine on embedded tomcat for development purpose but on weblogic server appears this problem.

Answer 1

I've fixed the problem by adding the class org.springframework.web.servlet.support.DefaultFlashMapManager that implements the interface org.springframework.web.servlet.FlashMapManager in the project.
