while integration struts with spring "Servlet action is notavailable"

[Amit Jain]

I hava created a working Struts 1.2 webapp.

I want to add Spring support and I have tried to use
ContextLoaderPlugIn and DelegateProxy for this, but I recive an 404
error saying Servlet action is not available where action referes to
the org.apache.struts.action.ActionServlet class defined in web.xml.

I can't seem to fix this and would appreciate any help solving this
matter.


struts-config.xml
Code:

..
..
..
<action path="/springTest" type="no.rone.struts.SpringTestAction" />
..
..
..
<action path="/sindex"

type="org.springframework.web.struts.DelegatingActionProxy"
validate="false">
<forward name="success" path="/index.jsp"/>
</action>
<plug-in
className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation"
value="/WEB-INF/applicationContext.xml" />
</plug-in>
..

Code:

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://

<bean id="/sindex" class="ca.nexcel.books.actions.SpringIndexAction">

property>
</bean>
<bean id="productManager"

Does anyone have a clue?

In applicationContext.xml
replace line <bean id="/sindex"
class="ca.nexcel.books.actions.SpringIndexAction">
by
<bean name="/sindex"
class="ca.nexcel.books.actions.SpringIndexAction">
