Struts DispatchAction problem action not called second time.

[Kunjal Shah]

I think I should try to explain my problem a little better. As I said I am having trouble with DispatchAction action handling. The method within DispatchAction is not called the second time after initial request is processed ( i.e. ActionForm is populated inside my action class and forwarded to jsp file which displays the values in a TreeView). Now I wanted to know if I can use the same DispatchAction method -- selectCMAForm shown below with the same ActionForm and ActionMapping Login.do for events within TreeView, I was asking because I dont see the DispatchAction method called in the logs (System.out.println). I know that my ActionForm would be mostly reset() due to the request scope, but I am populating my form inside the Action and dont need the contents. I am very new to Struts and would appreciate any help or advice.

Hello,

I am new to Struts Framework. I am developing a Struts based JSR 168 portlet on WepSphere Portal 5.1 platform. I needed some help with an error I am getting in designing a Tree based hierarchial View in the portlet (am using the struts-layout extension library to design the TreeView). I am using Struts DispatchAction class to forward the user to the Tree based navigation. This is the jsp code fragment for this.

<html:form urlType="standard" action="Login.do">

Here the unspecified method in the DispatchAction class is called fine. The tree is populated inside my Action class and displayed through a JSP (ActionForward). Now I am trying to associate action handling with the links within Tree View (MenuComponent) doing something like this in my Action Class.

 channel.setLocation("Login.do?method=selectCMAForm&cellPointId=" + form.getChannel()); 

Here channel is my MenuComponent -- the last node within the tree..

This dosent seem to work and selectCMAForm method within the Action class is not called. I get this error in my Websphere portal log file.

2005.08.28 17:54:19.285 E com.ibm.wps.engine.tags.PortletRenderTag doStartTag
javax.portlet.UnavailableException: Creation of WrapperServlet failed
at com.ibm.wps.pe.om.definition.impl.ServletDefinitionImpl.createWrapper(ServletDefinitionImpl.java:367)....

class com.ibm.wps.state.nls.inputmediators.exceptions.NlsCannotInterpretStateException: Unspecified message ()
....


I tried to call any outside link through my action class like

channel.setLocation("http://www.google.com");

. This works.

I also tried to call my DispatchAction method directly through the jsp like

<html:form urlType="standard" action="Login.do?method=selectCMAForm&cellPointId=customer"> 

This also works and the selectCMAForm method is called. May be I am missing something here. I am new to Struts framework and would appreciate any help or tips with this problem. I am using an ActionForm which is getting populated inside the Action class.

Thanks
- Kunjal.
