How i can get request header parameter details while the page is trying to load...

 

 

 

okka page lo 5 'comments' button vunnayi to add comment for each difference place in a tab ki... so once we add the comment to that particular tab next time while loading it should show as 'comment(1)' as button name.. which has comment already..

 

 

so aa comments ani db lo store chesthunamu and okka reqid dwara pull chesthunamu... i can get reqid but adhi click chesi nappudu vasthundhi.. page load ayyitappudu ela tesukoni ravali aa req id ne ..  ekkada parameters only click on button chesinappudu vasthundhi not at loading the page...

 

 parameters = FacesContext.getCurrentInstance().getExternalContext().

            getRequestParameterMap();

this is in u r ManagedBean

 

 

Map<string,String> headerMap =  FacesContext.getCurrentInstance().getExternalContext().

            getRequestParameterMap();

 

//add a simple method to get values from Map

 

public static Object getValuefromMap(Map map, Object key) {

return map.get(key);

}

 

 

inside your XHTML use this 

 

 

#{fn:getMapValue(bean.headerMap , 'key')}

 

 

don't foget to add JSTL reference to u r XHTML page - http://java.sun.com/jsp/jstl/functions
