Hi,
to read a parameter out of the url of my rap servlet I use the following:
HttpServletRequest request = RWT.getRequest();
System.out.println(request.getParameter("id"));
Is it also possible to change the parameter values in the url? How can I
achieve this? I need to write a parameter value in the url so that another
application can read it.
Thanks,
Fanny

Hi,
this is common servlet technology. The request object provided by the
server is readonly regarding the request parameters. To share key-value
pairs with 'other' applications regarding the same request you may use
HttpServletRequest#setAttribute(String,Object). For RAP internal
exchange you may use the convenience RWT#getSessionStore()
implementation.
I'm sorry but I don't get the second question. What is it exactly that
you are trying to do, what do you mean by 'other application'?
Ciao
Frank

Hi,
this isn't possible since RAP uses AJAX for request processing. This
means the URL in the browser which represents the initial session
request doesn't change anymore. There is only one document for the
complete user session, no browser history etc. RAP (as with any
AJAX-app) does not replace the current document with a new document each
time a request is proceeded, the response of RAP-Requests are used to
modify the current loaded document subsequently.

Hi,
thanks for your answer.
I need to add to the url that is displayed in the browser a new
parameter.
So my url is: http://127.0.0.1:2028/rap?startup=default
When a button is pressed I want to change the url so that it displays:
http://127.0.0.1:2028/rap?startup=default&id=1 for example.

Hi,
ok, I understand that I canŽt change the url within one user session. But
I could start a new session with a changed url, couldn`t I? Would this be
possible or wouldnŽt this change the browser url?
Greetings,
Fanny

Hi,
that's true, using a link with a changed URL would change the entry in
the URL-Field in the browser.
