Struts forward question

[Geoffrey Falk]

In Struts, I can forward from an Action to a JSP. But how do I get an Action to forward control to another Action? I am trying to chain several actions together before finally invoking a JSP.
My code looks like this:
invoker.jsp:

  <html:form action="action1"> ... </html:form>

Action1.java:

public class Action1 extends Action {
  ActionMapping perform(
    ActionMapping mapping, ....) {
    ....
    return mapping.findForward("action2");
  }
}

struts-config.xml:

<action path="/action1"
  type="org.myapp.Action1"
  name="inputToAction1"
  scope="request"
  input="/invoker.jsp">
  <forward name="action2" path="/action2.do"/>
</action>
<action path="/action2"
  type="org.myapp.Action2"
  name="beanSetByAction1"
  scope="request"
  input="/invoker.jsp">
  <forward name="success" value="/result.jsp"/>
</action>

Am I doing this right? When I invoke action1 from invoker.jsp, I get an Error 500 which says, "Cannot get request dispatcher for path null". The Tomcat log file says, "2002-10-18 16:51:34 StandardContext[/portal]: Mapped to servlet 'action' with servlet path '/action2.do' and path info 'null' and update=true"
What does path info 'null' mean?
Thanks for your help.

Hi Geoff,
presumably your Action2.java looks like this:

  
public class Action2 extends Action {
  ActionMapping perform(
    ActionMapping mapping, ....) {
    ....
    return mapping.findForward("success");
  }
}

What version of struts have you got?
Also you don't need to specify the input attribute for the mapping unless attribute validation=true
You have specified the form-beans in struts-config as well?
