Hello,
I have problem with chaining struts actions. I use dispatched actions in
chain in my application and it works fine on tomcat without jetspeed. On
the jetspeed it freeze everytime I try forward to another action
handler.
Here is my config:
Jetspeed 2
<action path="/agreementHandler" name="agreementsListForm"
type="com.cleverbee.hci.test.struts.action.AgreementHandlerAction"
scope="session" validate="false" parameter="op">
<forward name="list" path="/agreement_list.jsp" redirect="true"/>
</action>
<action path="/creditCardHandler" name="creditCardForm"
type="com.cleverbee.hci.test.struts.action.CreditCardHandlerAction"
scope="session" validate="false" parameter="op">
<forward name="show" path="/cc_activate.jsp" redirect="true"/>
<forward name="storno1" path="/agreementHandler.shtml?op=list"
redirect="true"/>
<forward name="storno2" path="/agreementHandler.shtml?op=list"/>
</action>
Class CreditCardHandlerAction
....
public ActionForward storno(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
Exception {
.....
return mapping.findForward("storno1"); // <==== it freeze now
- blank page is displayed
}
Logging provides me information, that method "list" in agreementHandler
was executed (include forward "list"), but blank page is displayed
instead of page agreement_list.jsp!
Is there any workaround or fix for that? Please help.
I have little to go by as your information is still too limited.
In the future, try to be more specific and especially provide *how* you invoke a
certain action or page, e.g. through a portlet ActionUrl or portlet RenderUrl.
In this case, I've got the feeling the creditCardHandler might be invoked during
the RenderRequest processing. If true, then you shouldn't be having a
redirect="true" on
the forward you invoke because redirecting isn't possible during (Portlet)
rendering.
Remove the redirect="true" in that case from your config and it should work.
On another note: action chaining isn't really supported nor a recommended way of
using Struts by the Struts guru's themselves.
Thanks
Lubos
