JavaServer Faces - How to get values from a query string in URL in a jsf page?

if i have a url, http://my.com/?name=john+smith, how do i get the values from that url in a jsf page and then pass those values to a servlet? i know how to do that in jsp using "request.getParamter("name")" and save it in a bean and then forward to a servlet. But what about in jsf?

Hello,

Try this:

Map requestMap = FacesContext.getCurrentInstance().getExternalContext().getRequestMap();
String name = (String) requestMap.get("name");
If isn't worked one of these methods probably will solve your problem.
FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap();
FacesContext.getCurrentInstance().getExternalContext().getRequestHeaderMap();
hth.

You need the RequestParameterMap. But better design is to just define managed properties in the faces-config.xml so that those params will be put in the backing bean 'automatically'. Also see http://balusc.xs4all.nl/srv/dev-jep-com.html under the header "Passing GET parameters".

But isn't more easy do this in the code ?

What is the benefits to do this in the faces-config.xml ?

Thank you in advice.
