Hi all,
in my JSP files, I include a a general header file
that contains a standard header, logo etc as well as
displaying the user currently logged in and a logout
button.
Since my web app is to be multi-lingual, I also wanted to
have the language switch-over in that toolbar.
What I did is the following:
<form action="MyServlet" method=POST>
Current language: <%=session.getAttribute("lang");%>
<input type=submit value="Toggle language" name=tglLang>
Which works to switch the language, however, since I
adress the MyServlet "application home page", the
language switch will always go back there.
What I really want is to reference the same page that is
currently displayed. Since the header is included, this
URL cannot be hardcoded but has to be constructed from
any one of page, pageContect, session, request, response,
... variables available in the JSP.
However, I did not manage to construct a FULL
self.reference containing server name, page name and
path, session URL (in case of rewriting) and GET request
parameters.
I would not like to use JavaScript for this.
Any thoughts anybody ?
best regards, tom.
