Hi Techies,
I'm integrating my existing Struts1 application with Struts2
using the plugin,
My web.xml,
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.nav</url-pattern>
</filter-mapping>
and it contains struts1 configuration as well,
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
So if the URL ending with xxx.nav which takes me to Struts.xml file resides
in the classes folder,
My Struts.xml file,
<?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" />
<constant name="struts.action.extension" value=",nav" />
<package name="sample" namespace="/" extends="struts1-default">
<interceptors>
<interceptor name="makeReservationForm"
class="com.opensymphony.xwork2.interceptor.ScopedModelDrivenInterceptor">
com.formcomponent.ReservationFormBean
makeReservationForm
session
</interceptor>
<interceptor-stack name="sample-example">
<interceptor-ref name="staticParams"/>
<interceptor-ref name="makeReservationForm"/>
<interceptor-ref name="modelDriven"/>
<interceptor-ref name="basicStack"/>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="sample-example"/>
<action name="ReservationInitializeStart"
class="org.apache.struts2.s1.Struts1Action">
com.actions.ReservationInitializeAction
<interceptor-ref
name="sample-example"></interceptor-ref>
<result name="SUCCESSFUL">reservation_stay.jsp</result>
<result name="FAILURE">welcome.jsp</result>
</action>
</package>
</struts>
While hitting with the URL
http://localhost:90/Application/ReservationInitializeStart.nav, am facing
null pointer exception as below,
Struts has detected an unhandled exception:
