When I access "http://localhost:8080/project/Song", dont appears any error, it works it lists some songs in the page. When I click on a song I go to a URL "http://localhost:8080/SongPage?name=A+Tribe&id=201" but here it appears a 404 error, maybe because the url has parameters, accessing this URL appears an error:
HTTP Status 404 – Not Found
Description The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Do you know why?
Maybe its because of this urlPattern below:
@WebServlet(name ="SongPage", urlPatterns = {"/SongPage"})
I have this servlet below:
@WebServlet(name ="Song", urlPatterns = {"/Song"})
public class Song extends HttpServlet {
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
QueryManager qm = new QueryManager();
ArrayList<ArrayList<String>> result = qm.Songs();
qm.closeConnections();
request.setAttribute("result", result.get(0));
request.setAttribute("id", result.get(1));
RequestDispatcher view=request.getRequestDispatcher("songList.jsp");
view.forward(request,response);
}
}
In songList.jsp i have this:
<c:forEach items="${result}" var="item" varStatus="status">
<a href="/SongPage?name=${result[status.index].replace(" ","+")}&id=${id[status.index]}"> ${result[status.index]} </a> <br />
</c:forEach>
SongPage.java:
@WebServlet(name ="SongPage", urlPatterns = {"/SongPage"})
public class SongPage extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String name = request.getParameter("name").replace("+"," ");
...
}
