Question

Is it possible to pass parameter from a JSP page to a JSF page’s backing bean?

JSP page is popup window open when I invoke a button in JSF page and my selected value in JSP page, I should be able to pass to JSF’s backing bean.

P.S. When I add comment and I put @anyname when someone replies, @namyname part is getting truncated.

Update 1

To get the selected value from JSP to bean I did a crude approach.

I added the the following in JSP

String str = request.getParameter("selectname");

and assigned string str to a hidden field

 <input type="hidden" name="hid" value="<%=str%>"  /> 

and in my bean I am getting the value like the following

logger.info("jsp value "+FacesContext.getCurrentInstance().getExternalContext()
               .getRequestParameterMap().get("hid"));

This almost works except I always gets the value which I previously selects.
E.g. First time when I selects 1 and value returned in bean is null, second time when I selects 2, value returned is 1.

How could I get the currently selected value in my bean?

First, if your JSF view technology is JSP, then you can use the <h:> tags in the jsp and it becomes straightforward 0 just add a <h:commandButton action="#{yourBean.yourMethod}" />

Otherwise, you still can perhaps, but I’d suggest that you make your popup also a JSF page. JSF and JSP don’t coexist well. If you really must retain the situation, then you can try to emulate a JSF POST request to the target jsf URL.
