Carlos, Hello!

This error is still available.

Some more details:

The log shows
17:11:27.239 LoginServlet.doPost: doPost - Forward to /orderServlet [53]
when it gets stuck.

In the code
LoginServlet.doPost sets url="/orderServlet" and calls
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher(url);
dispatcher.forward(request, response);

When you add a product then the basketServlet is called from a form in index.jsp. That works without problem and forwards to /basket.jsp:
17:36:08.391 BasketServlet.doGet: Forward to /basket.jsp [35]

When you click on Login then the html code
<input type="button" onclick="window.top.location.replace('./loginServlet');" name="Login" value="Login">
is used without problem and finally puts you into login.jsp.
It shows:
18:00:34.962 LoginServlet.doGet: Forward to /login.jsp [56]

In that case LoginServlet.doGet is setting url to "/login.jsp" and also using
RequestDispatcher dispatcher = getServletContext().getRequestDispatcher (url);
dispatcher.forward (request, response);

So it seems the page flow
from jsp to servlet is working and
from servlet to jsp is working but
from servlet to servlet is not working.

Could it be a problem related to the equinox servletbridge?
