Answer 1

I was facing the same problem. Everybody was suggesting that my jar version was wrong but the problem was different.

I was adding the required jar in project, but that was not working.

So removed the jar from project and added those jar in my TOMCAT server lib folder and that worked.

Answer 2

the solution is in pom.xml;

<dependencies>
    <dependency>
        <groupId>org.apache.struts</groupId>
        <artifactId>struts2-core</artifactId>
        <version>2.3.1.2</version>
    </dependency>
</dependencies>


<packaging>war</packaging>
<build>
    <finalName>struts-2.3-hello-world-example</finalName>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <configuration>
                <webXml>web\WEB-INF\web.xml</webXml>
            </configuration>
        </plugin>
    </plugins>
</build>
