Hi,

I am using Liferay, Icefaces.

I would like to get a parameter from a URL
e.g. www.hostname.com/item?id=12345

I would like to display the item details according to the id number in the request parameter.
How can I get the "id" value from a JSF Bean?

Thank you very much
Best Regards,
Elvin

Hi,

as you are working on portlets, you cannot get "normal" request parameters. You can only get request parameters which are "sent" to the portlet itself.

If you have this URL:
http://somserver/somepage?p_p_id=some_portlet_id_INSTANCEID&p_p_action=0&p_p_state=maximized&param=value
you can get the value of the "param" parameter only in the portlet whose ID is "some_portlet_id"

kind regards
Tobias

Hi,

me again.

If you have the correct URL for the portlet you can get the values with this code:

1        FacesContext context = FacesContext.getCurrentInstance();
2        Map<String, String> paramMap = context.getExternalContext().getRequestParameterMap();
3        String projectId = paramMap.get("param");

Hi Tobias,

Thank you for your answer and the code, it works.

Actually I was wondering "PortalUtil" could give us some tricks to access the HTTPServlet and
hence the request parameters.....

I tried below but all throws exceptions
============================================

try {
logger.debug(" --- PortalUtil ---");
logger.debug("getPathFriendlyURLPublic = " + PortalUtil.getPathFriendlyURLPublic());
logger.debug("getCurrentURL = " + PortalUtil.getCurrentURL((PortletRequest) context.getExternalContext().getRequest()));

HttpServletRequest request = PortalUtil.getHttpServletRequest(
(PortletRequest) context.getExternalContext().getRequest());

logger.debug(" id = " + request.getParameter("id"));
logger.debug("HttpServletRequest Map = " + request.getParameterMap());
} catch (Exception e) {
logger.error("Error", e);
}

try {
HttpServletRequest request =
(HttpServletRequest) context.getExternalContext().getRequestMap().get("com.liferay.portal.kernel.servlet.PortletServletRequest");
logger.debug(" --- com.liferay.portal.kernel.servlet.PortletServletRequest ---");
logger.debug(" id = " + request.getParameter("id"));
logger.debug("HttpServletRequest Map = " + request.getParameterMap());
} catch (Exception e) {
logger.error("Error", e);
}

Hi,

Actually, I would like to have make a friendly URL.
Let's take a liferay's example, to getting back to this post, we can use the following link

http://www.liferay.com/web/guest/community/forums/-/message_boards/message/1994365

However, this forum is actually a portlet, right? Liferay don't need to provide a portlet Id to retreive this post.
So, I guess there is someway(or tricks?) to get the request parameters without passing the portlet Id.

Please kindly help if anybody knows the way to do it.

Many thanks,

Best Regards,
Elvin

Hi,

liferay is working with struts... the URL you can see is a struts-url where the struts servlet includes some jsp pages to the servlet response. Using JSF you always have your fix URL's to your JSP/XHTML pages. You cannot have such URL's in JSF...

Hi Tobias,


I don't quite get the point.....
Do you mean, using struct to build a portlet, the portlet can get the request parameters in the URL,
(the struct servlet can get the request param and pass to the jsp that it includes...right?)
but using JSF, it cannot?


Thank you very much.

Hi,

Struts and JSF are 2 completely different techniques.

In Struts, your actions are encoded in the URL. The action that a portlet is executing is defined with this URL.
I'm not a Struts specialist, so I cannot explain it with more details...

Hi Elvin,

actually I have some experience with ICEfaces. I developed several portlets with ICEfaces for my company.

And the code snippets are taken from my productive portlets. So I think they do work.

What did you do so far? Configuration, code, ....

Hi Tobias,

That is great that you have experience! Thanks advance!

My case is that.

In my icefaces page, I use the following code to generate a URL that contains a portletId and a param that is an id of a product

Code
===========================================================
RenderResponse renderResponse =
(RenderResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
PortletURL portletURL = renderResponse.createActionURL();
portletURL.setParameter("id", "12345");
renderURL = portletURL.toString();
logger.debug("portletURL = " + portletURL.toString());

URL generated
===========================================================
http://localhost:8080/web/item?p_p_id=product_detail_portlet_WAR_WebAppName_INSTANCE_27qA&amp;p_p_lifecycle=1&amp;p_p_state=normal&amp;p_p_mode=view&amp;p_p_col_id=column-2&amp;p_p_col_count=1&amp;_product_detail_portlet_WAR_WebAppName_INSTANCE_27qA_id=12345

In the item page i.e. http://localhost:8080/web/item, it call a "showDetail" method via the JSF page
(Same portlet, same jspx page that generate the URL, )
============================================================================
<ice:panelGrid rendered="#{productBean.showDetail}" cellpadding="2" cellspacing="2" width="100%" columns="2">
...
...

In the showDetail method of the bean, I try to print out all the values into my log file
================================================================
FacesContext context = FacesContext.getCurrentInstance();
if (logger.isDebugEnabled()) {
Map paramMap = context.getExternalContext().getRequestParameterMap();
Iterator iter = paramMap.keySet().iterator();
while (iter.hasNext()) {
String paramKey = (String) iter.next();
logger.debug("paramKey = " + paramKey + " value = " + paramMap .get(paramKey).toString());

}
}
return context.getExternalContext().getRequestParameterMap().get(key);


---> And There has no value contains in the RequestParameterMap()


So I try "getRequestMap" instead
========================================================
FacesContext context = FacesContext.getCurrentInstance();
if (logger.isDebugEnabled()) {
Map paramMap = context.getExternalContext().getRequestMap();
Iterator iter = paramMap.keySet().iterator();
while (iter.hasNext()) {
String paramKey = (String) iter.next();
logger.debug("paramKey = " + paramKey + " value = " + paramMap.get(paramKey).toString());

}
}
return context.getExternalContext().getRequestMap().get(key);



There indeed some values contained in the requestMap but not the id that I have passed to the instance.

Hi,

why do you need to get the request paramter?

If I understand you correct, you are not trying to pass the parameter to a different portlet, right? You are trying to open the details page in the same portlet!

So you don't need that stuff at all. Is this your first JSF application?

If yes... you might need to learn some more things about that. If not.... did you never work with session-scoped beans where you can store a selected item and retrieve it in a different page?

kind regards
Tobias

Hi Tobias,

Yes I am not trying to pass a param to a different portlet....

Yes I have done some JSF before, I know it's not a usual way (may be not proper way also)
to get the param from the URL.

However, it's because after user have done a search, I want to let the user to
bookmark the search result and come back to the searched item again,
by using the same URL.

This is the reason behind.

I have make a little modification of the Liferay Journal Article Portlet
using similiar method as above. The generated URL can always leads to the
same result. (Even works for a different portlet on a different page)
i.e. The user can bookmark the URL.

However, using JSF I have difficulties to doing so.
I don't know if there is a way to get the param from the URL.
(I think I must miss something, as JSF did provide the API,
I think there is a way to get the param....)

Do you have any idea what I did wrong?


Thank you very much.

Hi,

OK.. so now I see clearer. In fact you are trying to pass a parameter to a different portlet. Not during search, but when coming back to the result (after bookmarking it).

Actually I don't know what you are doing wrong as the code I posted is working for me.

Maybe the generated URL is not correct. Here is what you posted: http://localhost:8080/web/item?p_p_id=product_detail_portlet_WAR_WebAppName_INSTANCE_27qA&amp;p_p_lifecycle=1&amp;p_p_state=normal&amp;p_p_mode=view&amp;p_p_col_id=column-2&amp;p_p_col_count=1&amp;_product_detail_portlet_WAR_WebAppName_INSTANCE_27qA_id=12345

I think there is a problem with the "&amp;". I assume the paramter is named "_product_detail_portlet_WAR_WebAppName_INSTANCE_27qA_id". Try this url:
http://localhost:8080/web/item?p_p_id=product_detail_portlet_WAR_WebAppName_INSTANCE_27qA&p_p_lifecycle=1&p_p_state=normal&p_p_mode=view&p_p_col_id=column-2&p_p_col_count=1&_product_detail_portlet_WAR_WebAppName_INSTANCE_27qA_id=12345

Hi Tobias,

Thank you for your reply...
I have tried to replace, however, it throws an exception.
I don't know what's wrong.
However, after I take out the following param, the portlet can show properly but the "id" value still unable to obtain.


&p_p_lifecycle=1&p_p_state=normal

Do you have any idea?

Thank you very much!

Hi,

actually you created an action URL. The generic portlet for JSF does not support this. You need to generate a "normal" render-URL. You don't need the action-URL at all as you simply render the portlet (from a portlet point of view) and process the data using JSF... JSF doesn't know anything about portlets.

kind regards
Tobias

The other solutions described here did not work for me within my portlet. I used the sample-jsf-1.1-sun-facelets portlet as a basis. After trying a number of different things I gained access to the request parameter using this code:

 1        ...
 2        FacesContext context = FacesContext.getCurrentInstance();
 3        Map<String,String[]> originalParams = getPortalRequest(context).getParameterMap();
 4        if (originalParams.get("articleId") != null)
 5            log.info("RequestParameter articleId: " + originalParams.get("articleId")[0]);
 6    }
 7
 8    public static ServletRequest getPortalRequest(FacesContext context) {
 9        Map<String,Object> requests = context.getExternalContext().getRequestMap();
10        for (String requestName : requests.keySet()) {
11            if (requests.get(requestName) instanceof HttpServletRequestWrapper) {
12                return ((HttpServletRequestWrapper) requests.get(requestName)).getRequest();
13            }
14        }
15        return null;
16    }

I hope you will find this useful,
