Subject Re: java.lang.InstantiationException: org.apache.struts.action.ActionForm
Date Wed, 30 Apr 2008 18:13:02 GMT

Hi,

Now I am migrating from struts1 to struts2.

In struts1 I have a homeAction which extends dispatchAction and it uses
homeActionForm.

I have configured it this way in struts.xml:

<interceptors>
<interceptor name="homeActionForm"
					
class="com.opensymphony.xwork2.interceptor.ScopedModelDrivenInterceptor">
	
		com.XXX.XXX.HomeActionForm
	
	homeActionForm
</interceptor>
<interceptor name="homePage"
						class="org.apache.struts2.s1.ActionFormValidationInterceptor">
	
														/org/apache/struts/validator/validator-rules.xml,
		/WEB-INF/validation-rules.xml, /WEB-INF/Validation.xml
	
</interceptor>

<interceptor-stack name="homeActionForm">
	<interceptor-ref name="staticParams" />
	<interceptor-ref name="homeActionForm" />
	<interceptor-ref name="modelDriven" />
	<interceptor-ref name="actionForm-reset" />
	<interceptor-ref name="basicStack" />
	<interceptor-ref name="homePage" />
	<interceptor-ref name="workflow" />
</interceptor-stack>
</interceptors>

<action name="loadPage"
	class="org.apache.struts2.s1.Struts1Action">
	
		com.XXX.XXX.homeAction
	
	<result name="load" type="tiles">/home.jsp</result>
</action>
