How can I store values in session?

[nlatha]

Hi,

How can I store values in session after successful execution of some action using webflow?

[ruipacheco]

I don't know if this is what you mean, but it should be something like this:

context.getFlowScope().setAttributes( context.getSourceEvent().getParameters() );

If you want to store something in the HTTP session (the post above puts something in the flow scope), use this:

((ServletEvent)context.getSourceEvent()).getRequest().getSession().setAttribute(...);

Hi ,

I used the following code

((Scope)(context.getFlowScope())).put("backRef","1 ");


Once I set the variable I am able to access successfully in jsp page as follows


c:if test="${backRef ==\"1\"}">
<a href="journal.toc?_flowExecutionId=${flowExecution Id}&_eventId=selectBackRef">Select Article</a>
</c:if>

It’s working fine. But I replaced
((Scope)(context.getFlowScope())).put("backRef","1 "); with

((ServletEvent)context.getSourceEvent()).getReques t().getSession().setAttribute(("backRef","1");

and it’s not working, backRef attribute is coming as null in jsp page.

Am I missing anything?

potential red herring warning

replace

c:if test="${backRef ==\"1\"}">

with

c:if test="${backRef =='1'}">

Might be nothing

All data in flow scope and request scope is made available to the JSP as request attributes, so you can simply do things like '<c:out value="${backRef}"/>'.

However, the content of the HTTP session is not directly available in the request attributes, so in that case you should do: '<c:out value="sessionScope.backRef"/>'.

Note that this is not related to the use of SWF. Read a few articles about the Servlet API and JSTL to find out more.

I found this code in an earlier post and thought that answers my question about "How to put objects into the HTTP session":

((ServletEvent)context.getSourceEvent()).getRequest().getSession().setAttribute(...);

It seems that ServletEvent has been deprecated, so I used this approach:

context.getExternalContext().getSessionMap().put(EsConsts.FLOW_TYPE, flowId);

That seems to do the job. Does anyone know if this is the proper way to do that?

yes, that is correct, as per ref docs and javadocs.
