Hi Frank:
According to your advice,I have create a new Servlet, registered it in
Plugin.xml file. The configuration code as follows:
<extension
point="org.eclipse.equinox.http.registry.servlets">
<servlet
alias="/test"
class="rapdemo.servlets.MyServlet"/>
</extension>
After it .
I added some codes in Button SelectionEvent . I have used two methods.
First:
String application = RWT.getRequest().getContextPath();
if (application.trim().equals(""))
application = "http://127.0.0.1:8080/test";
try {
RequestDispatcher rdis=RWT.getRequest().getRequestDispatcher("application");
rdis.forward(RWT.getRequest(),RWT.getResponse());
} catch (Exception e1) {
e1.printStackTrace();
}
Second :
String application = RWT.getRequest().getContextPath();
if (application.trim().equals(""))
application = "http://127.0.0.1:8080/test";
try {
RWT.getResponse().sendRedirect(application)
} catch (Exception e1) {
e1.printStackTrace();
}
MyServlet code as follows:
public class MyServlet extends HttpServlet {
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
resp.sendRedirect("http://ww.eclipse.com");
}
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
doPost(req, resp);
}
}
I got the error is requestFailed, code=302.
can i implement this in RAP??
Thanks for you help in advance.

Hi,
I think you got me wrong on what to do with the servlet. Please point your
browser directly to http://127.0.0.1:8080/test after launching the app. If
the redirect doesn't work here either this would probably point to a
problem in the equinox layer, since no RAP stuff is involved. In that case
you should look at the equinox forums. If the redirect works properly we
have to investigate further how the problem occurs in RAP.
Ciao

Hi,
maybe that's a problem with AJAX-Request mechanism. But that's just a
wild guess. I propose to file a bug for it, in the meanwhile something
similar than the solution I proposed in the 'Redirect user to another
page after closing application' thread will maybe work for you too.
Ciao

Hi:
First Thanks for your reply. It can be navigated to
Http://127.0.0.1:8080/test when I pointed it directory in browser.
But I don't known why it happens in Rap?
best regards
