Role of DispatcherServlet

[amit.goenka]

Hi Anita,
Please Check the Action in the success form in the form tag.Because the controller for the success page is associated with that action in the form.And hence the urlmapping in the xml definition file has to match with the action.Does these match?

[anita]

Hello,
Here are all my codes for AttachmentType-context.xml, web.xml, ViewController and searchcontroller. Now I have little similar question that I'm creating page urls in handleReanderRequestinternal, if I click on any of this this it takes me to related page and formbacking object method for thta page controller runs but again if I try to submit some for by that page onSubmitAction for the ViewController runs.

Amit,
I did not quite get what you wanted to say can you please explain it to me.

Hi Anita,
What I am trying to say is that '/search' must come in the url on form submission.If its not coming that means that ur search.jsp file is not invoking that action at all.Your form in the search page if associated with a submit method then the corresponding action is to be referred.
Like
<form:form id="searchForm" action="search.do"/"search.htm" method="POST" commandName="searchCommand">
I might be wrong coz i havent worked with portlet at all.So If doesnt work like it Please ignore.

[anita]

That's the thing the when form submits and go to success view url doesn't change means /search doesn't come in url. I tried doing the following still url does not change, but if I submit the form I get
The requested resource was not found.
http://localhost:8080/user/ijus-spida/search.htm

<form:form id="searchForm" action="search.htm" method="POST">

Even though if I go to the page by clicking on link the url says action=search , but if I try to submit form there the ViewController get called.
I'm about to giveup on this.

thanks,
anita

[amit.goenka]

In the 12th post of this thread u had a code like this:

<bean id="urlMapping" class="org.springframework.web.servlet.handler.Sim pleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/View">View</prop>
<prop key="/AddAttachmentType">AddAttachmentType</prop>
<prop key="/search">SearchAttachmentType</prop>
</props>
</property>
</bean>

Try giving search.htm here.

[anita]

I've tried that, it says search.htm not found.
