Want to pass a parameter from prcessaction to Jsp Page

[Bikash Ghibila, modifié il y a 10 années.]

Hi All,

I want to pass a parameter from process action to jsp page.

For this I use actionrequest in the action page to set the value and
renderrequest to get the value but it is not working..


If i use session then it is working.

But i donot want to use session.

Please suggest how i solve this issue without session

you may try using Public Render Parameter to satisfy your requirement. Just google it and you should see some examples.

In your processAction method you should be able to call ActionResponse.setRenderParameter(String, String) and then call RenderRequest.getParameter(String) in order to retrieve the value in the doView method.

i assume you are using JSR 286 complaint portlet.
Just assign variable in processAction as
actionRequest.setAttribute("test", "from processAction");
And get the variable in doView or render or JSP as
renderRequest.getAttribute("test");

The getAttribute/setAttribute method will work in Liferay Portal because it uses a single HTTP POST to perform the ActionRequest and subsequent RenderRequest. But JSR 286 Spec doesn't mandate this. For example, the Pluto portlet container does the ActionRequest with HTTP POST, but returns a redirect which causes a subsequent HTTP GET that invokes the RenderRequest.
