Moved this into an appropriate category.

put jsr286dispatcher entry in your web.xml and portlet.xml file

web.xml entry:

<servlet>
<servlet-name>struts2</servlet-name>
<servlet-class>com.liferay.portal.kernel.servlet.PortletServlet</servlet-class>
<init-param>
<param-name>portlet-class</param-name>
<param-value>org.apache.struts2.portlet.dispatcher.Jsr286Dispatcher</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>struts2</servlet-name>
<url-pattern>/struts2/*</url-pattern>
</servlet-mapping>

portlet.xml entry:

<display-name>TestPortlet</display-name>
<portlet-class>org.apache.struts2.portlet.dispatcher.Jsr286Dispatcher</portlet-class>
<init-param>
<name>defaultViewAction</name>
<value>init</value>
</init-param>
<expiration-cache>0</expiration-cache>

And check whether you have all struts related jar files in your portlet or not

struts2-core-2.2.3.jar , struts2-portlet-plugin-2.3.1.1.jar , xwork-core-2.2.3.jar, ognl-3.0.1.jar, freemarker-2.3.19.jar, javassist.jar
