Cookie in Ajax Response deleted.. ?

[rosi75]

Hi

I'm trying for many hours to solve this problem. I found no docu about that.

I just try to add some cookies in a AJAX Respond. But it does not work. I also tried to put some headers into the response ("set-cookie...") but they will also be resetted during ajax response update..

Is it impossible to set any cookie by ajax-respond?

many thanks for any help.

perhaps some more exact information about that:

jsp:

<f:view locale="#{wopiBean.locale}">
<h:form id="wopidruck" onclick="tt_HideInit();" onkeydown="tt_HideInit();">
<a4j:region id="berater_region" renderRegionOnly="true" >
<h:inputText styleClass="input input_FeldVOLL" value="#{wopiBean.mapper['NACHNAME'].value}"
id="nachn">
<a4j:support id="nachn_a4j" event="onchange" ajaxSingle="true" eventsQueue="person" />
</h:inputText>
</a4j:region>
</h:form>

This section is just one inputfield with a value. This values should be sent as a cookie to the client - on every field change !

But i does not work. The action method which I call in h:inputText does the following:

...

HttpServletResponse response = (HttpServletResponse) JsfHelper.getFacesContext().getExternalContext().getResponse();

Cookie cookie = new Cookie(Konstants.COOKIE_SIRNAME,sirname) );
cookie2.setMaxAge( Konstants.COOKIE_TIMETOLIVE );
response.addCookie( cookie );
...

at the end I get an ajax-response without set-cookie header...

I think Richfaces isn't prepared for sending cookies in responses.

Can somebody who knows about confirm this?

This is a working code from my sample:

 public String setCookie() {
 ExternalContext externalContext = FacesContext.getCurrentInstance()
 .getExternalContext();
 HttpServletResponse response = (HttpServletResponse) externalContext
 .getResponse();
 Cookie cookie = new Cookie("test", "Setted at time "
 + System.currentTimeMillis());
 cookie.setMaxAge(60 * 60 * 24 * 365);
 response.addCookie(cookie);
 return "verify_cookie";
 }

 public String getTestCookie() {
 ExternalContext externalContext = FacesContext.getCurrentInstance()
 .getExternalContext();
 HttpServletRequest request = (HttpServletRequest) externalContext
 .getRequest();
 Cookie[] cookies = request.getCookies();
 for (int i = 0; i < cookies.length; i++) {
 if ("test".equals(cookies.getName())) {
 return cookies.getValue();
 }
 }
 return null;
 }

This methods used on a page:

 <a4j:form>
 <h:outputText value="Cookie value: #{bean.testCookie}"/>
 <a4j:commandButton action="#{bean.setCookie}" value="Set Cookie by AJAX"/>
 <h:commandButton action="#{bean.setCookie}" value="Set Cookie in POST"/>
 </a4j:form>

hey thanks for your reply.

I tried to do so. I saw that I am using h:form instead of a4j:form.. but also this didn't solve my problem.

so, perhaps my system is already a bit complicate for such easy solution. perhaps I will try your solution in an clean and young environment.

regards.

Hi, rosi75!
You could try this code:

public class CookieBean {

 private String testCookie = null;

 public String setTestCookie() {
 ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
 HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();
 Cookie cookie = new Cookie("test", "Setted at time " + System.currentTimeMillis());
 cookie.setMaxAge(60 * 60 * 24 * 365);
 response.addCookie(cookie);
 return "verify_cookie";
 }

 public String getTestCookie() {
 ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
 HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();
 Cookie[] cookies = request.getCookies();
 for (int i = 0; i < cookies.length; i++) {
 if (cookies.getName().equals("test")) {
 testCookie = cookies.getValue();
 return testCookie;
 }
 }
 return null;
 }
}

The usage of these methods and testCookie property on a page:

<h:form>
 <h:outputText id="text" value="Cookie value: #{cookieBean.testCookie}"/>
 <br />
 <h:panelGrid columns="2">
 <a4j:commandButton action="#{cookieBean.setTestCookie}" value="Set Cookie by AJAX">
 <a4j:support event="oncomplete" reRender="text" />
 </a4j:commandButton>
 <h:commandButton action="#{cookieBean.setTestCookie}" value="Set Cookie in POST" reRender="text"/>
 </h:panelGrid>
</h:form>

Actually I've used <h:form> and <a4j:form> equally successful.

Hi Alexander,

i get an ClassCastException if i try to set cookies the way you did:

Caused by: java.lang.ClassCastException: org.jboss.portletbridge.richfaces.BufferedResourceResponseWrapper cannot be cast to javax.servlet.http.HttpServletResponse

I am working on Jboss Portal 2.7.2 with PortletBridge 2.0.0.BETA and Richfaces 3.3.2.

maybe you have a porposition what is wrong?

thanks a lot

Hi

This forum is in the archive area and is not used.  I'll try to move this thread to the RichFaces area.

Thanks,
