Session Expiration Handling

atarifreak73 Jul 23, 2012 8:02 AM

Hello,

I have a problem with handling for session timeouts by ajax.

I have readed chapter 5.6. "Error handling" and have put the following entries in my web.xml to use A4J in Javascript:

    <context-param>
        <param-name>org.ajax4jsf.handleViewExpiredOnClient</param-name>
        <param-value>true</param-value>
    </context-param>

It dont works. Then I have write additional this to web.xml:

    <context-param>
        <param-name>org.richfaces.LoadScriptStrategy</param-name>
        <param-value>ALL</param-value>
    </context-param>

It dont also works. When I use the A4J-Object (A4J.AJAX.onExpired) in Javascript for errormessaging, I become from firebug the message "ReferenceError: A4J is not defined":

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html
        PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xml:lang="en" lang="en"
      xmlns:a4j="http://richfaces.org/a4j"
      xmlns:ui="http://java.sun.com/jsf/facelets">
    <ui:composition>
        <script type="text/javascript">
            A4J.AJAX.onExpired = function(loc, expiredMsg)
            {
                if (window.confirm("Ihre Sitzung abgelaufen: Beim Klick auf OK wird eine neue Sitzung gestartet!"))
                {
                    return '#{facesContext.externalContext.requestContextPath}/index.html';
                }
                else
                {
                    return false;
                }
            };
        </script>
    </ui:composition>
</html>

I use RF 4.2 and JSF 2.0.9.

What is my error in reasoning?

Thank You!

I have found another solution, I dont use the A4J-Object.

I didn´t know, JSF2 have a own Ajax-Object for Javascript. That´s my solution, and it works:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html
        PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xml:lang="en" lang="en"
      xmlns:a4j="http://richfaces.org/a4j"
      xmlns:ui="http://java.sun.com/jsf/facelets">
    <ui:composition>
        <script type="text/javascript">
            jsf.ajax.addOnError(function(data)
            {
                if (data.responseCode == 200)
                {
                    if (window.confirm("Ihre Sitzung abgelaufen: Beim Klick auf OK wird eine neue Sitzung gestartet!"))
                        self.location.href = "index.jsf";
                }
                else
                    alert(data.responseText);
            });
        </script>
    </ui:composition>
</html>

I have messed the documentation for RF 4.0 with RF 4.2. Chapter 5.6 means this: http://docs.jboss.org/richfaces/4.0.X/4.0.0.CR1/Developer_Guide/en-US/html/chap-Developer_Guide-Advanced_features.html#sect-Developer_Guide-Advanced_features-Error_handling

My painful located solution is also there (on the correct doc-page, at least a tip): http://docs.jboss.org/richfaces/latest_4_2_X/Developer_Guide/en-US/html/chap-Developer_Guide-Advanced_features.html#sect-Developer_Guide-Advanced_features-Error_handling
