JSF Request value on Page2

**mwildam** · 10-10-2008, 05:00 PM

I created a new JSF project in NetBeans and I managed displaying a page with some elements and a button. In the faces-config.xml I setup moving to Page2.jsp on submission.

Then - in the init method in the java file of page2 I want to get form values posted from page2.

How do I manage this in java code?

And how do I retrieve the session id?

I didn't find helpful information searching.

you can get session id by getting Facesconttext object.

FacesContext context = FacesContext.getCurrentInstance();
HttpSession session = (HttpSession) context.getExternalContext().getSession(false);
session.setAttribute(”sessionObj”, mySession);

and

i didnt get what exactly u want for the request fields.
and by what iam understanding you can get the from field values. just u post the values through <inputhidden > tag and maintain the scope in session then u can get the values where do u want

The request-question was about normal form fields - when I have a second page and I want to retrieve the values of the form fields posted from page1 to page2 - how to do it?

Thanks for your hints - playing a little around starting from your suggestions I found out how to retrieve parameters (just some dirty sample):

Java Code:

        FacesContext finst = FacesContext.getCurrentInstance();
        ExternalContext ext = finst.getExternalContext();
        HttpSession session = (HttpSession) ext.getSession(false);
        Enumeration<String> atts = session.getAttributeNames();
        result = "Session attributes: \r\n";
        while (atts.hasMoreElements())
        {
            String attrName = atts.nextElement();
            result += attrName + "=" + session.getAttribute(result) + "\r\n";
        }
        result += "\r\n\r\n";

        Iterator<String> it = ext.getRequestParameterNames();
        Map props = ext.getRequestParameterMap();
        while (it.hasNext())
        {
            String pName = it.next();
            result += pName + "=" + props.get(pName).toString() + "\r\n";
        }
