Why multiple packages are not working in Struts 2?

Question

This is my struts.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts 
Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<include file="struts-test.xml"></include>
<include file="struts-data.xml"></include>
<include file="struts-empty.xml"></include>
</struts>

This is my struts-data.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts 
Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.devMode" value="true" />
<package name="default" namespace="/data" extends="json-default">
<action name="getData" class="jsonResponse"> 
<result type="json" />
</action>
</package>
</struts>

This is my struts-test.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts 
Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="default" namespace="/test" extends="struts-default">
<action name="getTest" class="TestClass"> 
<result name="success">/success.jsp</result>
</action>
</package>
</struts>

This is my struts-empty.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts 
Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<package name="default" namespace="/empty" extends="struts-default">
<action name="getEmpty" class="EmptyClass"> 
<result name="success">/empty.jsp</result>
</action>
</package>
</struts>

In the above code first include file in struts.xml only working Like struts-test.xml is working. If I change the order like this

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts 
Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<include file="struts-data.xml"></include>
<include file="struts-test.xml"></include>
<include file="struts-empty.xml"></include>
</struts>

Then struts-data.xml file only working.

Why this is happening? Any solution?

I am getting this Exception:

SEVERE: Could not find action or result
/strutsJSON/data/getData.action

I think the order is important in struts, if the files are related — Vishnu T S, Jan 22 '18 at 06:11

The tag <include> is self-closed, i.e. should not have a body.

<include file="struts-test.xml"/>
<include file="struts-data.xml"/>
<include file="struts-empty.xml"/>
