Struts + Spring Integration issue with struts-config.xml

I am trying to integrate Struts with Spring. Struts alone is working fine. However when I am trying to put:

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
        <set-property property="contextConfigLocation"
            value="/WEB-INF/lib/WebApplicationSpringContext.xml" />
    </plug-in>
    <controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />

element in side struts-config.xml, The xml start throwing

The content of element type "struts-config" must match "(data-sources?,form-beans?,global-exceptions?,global-
 forwards?,action-mappings?,controller?,message-resources*,plug-in*)".

Following is my struts-config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN"
"http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<struts-config>

    
    <form-beans>
        <form-bean name="userForm"
            type="com.sample.form.UserForm" />
    </form-beans>

    <action-mappings>
        
    <action path="/user" type="com.sample.action.UserAction"
            name="userForm" scope="request" validate="true">
            <forward name="success" path="/WEB-INF/jsp/welcome.jsp" />
            <forward name="failed" path="/WEB-INF/jsp/user.jsp" />
        </action>

    </action-mappings>

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
        <set-property property="contextConfigLocation"
            value="/WEB-INF/lib/WebApplicationSpringContext.xml" />
    </plug-in>

    <controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor" />

</struts-config>

Following is WebApplicationSpringContext.xml

<?xml version="1.0" encoding="UTF-8" ?>

<beans:beans xmlns="http://www.springframework.org/schema/security"
    xmlns:beans="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p"
    xmlns:tx="http://www.springframework.org/schema/tx" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <beans:bean name="/user" id="user"
        class="com.sample.action.UserAction">
        <beans:constructor-arg index="0" value="sample" />
    </beans:bean>

</beans:beans>

I am stuck with struts-config.xml.

The content of element type "struts-config" must match "(data-sources?,form-beans?,global-exceptions?,global- forwards?,action-mappings?,controller?,message-resources*,plug-in*)".

Try putting:

<controller processorClass=...

above:

<plug-in className="

meaning switch the tags order
