[flexcoders] Managing (http)session data from java code

[vttanhua]

I'm trying to access http session from java code (separate EJB3 
project)(through FlexContext.getHttpRequest())
 but when I'm trying to use my class from other java classes I get 
nullpointer exception for FlexContext.getHttpRequest().
So am I missing some important point here?

I have created a java class like this:
        public class SessionRO {
                
                public HttpServletRequest request = null;
                public FlexSession session = null;
                public SessionRO() {
                        request = FlexContext.getHttpRequest();
                        session = FlexContext.getFlexSession();
                }

                
                public String getAttribute(String keyName){
                        return (String)FlexContext.getHttpRequest
().getAttribute(keyName);
                }
                public void setAttribute(String keyName, String value)
{
                        FlexContext.getHttpRequest().setAttribute
(keyName, value);
                }
