You could create a filter that is mapped to "/*" and does a forward to
your jsp.
This one remembers the original path:
public class ForwardFilter implements Filter
{
public static final String SERVLET_PATH =
ForwardFilter.class.getName() + ".servletPath";
private String target;
public void destroy()
{
}
public void doFilter(ServletRequest request, ServletResponse
response, FilterChain chain)
throws IOException, ServletException
{
request.setAttribute(SERVLET_PATH, ((HttpServletRequest)
request).getServletPath());
request.getRequestDispatcher(target).forward(request, response);
}
public void init(FilterConfig config) throws ServletException
{
target = config.getInitParameter("target");
}
}

Hi,
I'm using GWT and GAE. I want to serve my project's one and only jsp
file no matter what url is entered by the user in their browser. So
the web.xml file looks like this:
<welcome-file-list>
<welcome-file>UserMaps.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>indexpage</servlet-name>
<jsp-file>UserMaps.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>indexpage</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
when I run this locally, it works fine. Any of the following urls
serve my gwt app with UserMaps.jsp:
http://localhost:8888/
http://localhost:8888/JohnDoe
http://localhost:8888/JaneDoe
when I publish to GAE, it stops working, none of the urls can find
UserMaps.jsp:
http://usermaps.appspot.com/
http://usermaps.appspot.com/JohnDoe/
http://usermaps.appspot.com/JaneDoe/
I'm not sure if this should work, I'm looking at the reference here:
http://code.google.com/appengine/docs/java/config/webxml.html#The_Welcome_File_List
My real goal is to support a twitter-like url mapping scheme where a
user can enter my domain/username, and I'll show them their customized
user page (by pulling some info out of the data store and dynamically
rendering a page for them),
Thanks
