Java Forum / General / March 2006JSP redirection
Hello, I have a JSP page a.jsp. My server web is Apache and I use Tomcat. Apache has a known break : it doesn't stop cross-site scripting. So in my JSP, I check the URL to see if the "<" character is not present. If it is present, I want to redirect the user to an error page (which can be in another server). If it is present, I continue to execute my page a.jsp. I use response.sendRedirect() but it doesnt't worf. Has anybody got an idea ? Thanks Delphine you can use RequestDispatcher rd=request.getRequestDispatcher("url") method followed by rd.forward(request,response) also.i don't know whether it works with two servers....i have used this only with a single server.please try it Thanks... I did what you said but I have the following error : java.io.IOException: Stream closed org.apache.jasper.runtime.JspWriterImpl.ensureOpen(JspWriterImpl.java:202) org.apache.jasper.runtime.JspWriterImpl.clearBuffer(JspWriterImpl.java:157) org.apache.jsp.content.appli_005fsol_005fiplanet.production.login_jsp._jspService(login_jsp.java:120) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:94) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:324) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:292) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236) javax.servlet.http.HttpServlet.service(HttpServlet.java:802) Need to make a precision : my page a.jsp is included in another page (login.jsp). Could it cause a problem ? > Hello, > [quoted text clipped - 5 lines] > a.jsp. I use response.sendRedirect() but it doesnt't worf. Has anybody > got an idea ? why doesn't it work? Do you have an error? An exception? What exactly goes wrong? I don't have an error, I am not redirected, that's all... When I called a.jsp my sendredirect works fine but when i called login.jsp that includes a.jsp it doesn't work... Any idea ? Delphine > I don't have an error, I am not redirected, that's all... > > When I called a.jsp my sendredirect works fine but when i called > login.jsp that includes a.jsp it doesn't work... Any idea ? Apparently redirect doesn't work with includes. Check the documentation of RequestDispatcher.include(). You can't change the response code or the headers > Apparently redirect doesn't work with includes. Check the documentation > of RequestDispatcher.include(). You can't change the response code or > the headers sorry, of course I missed to say that this is for dynamic includes. I assume this is what you are using No, the include in login.jsp is done like this : <jsp:include page="a.jsp" /> > No, the include in login.jsp is done like this : > > <jsp:include page="a.jsp" /> exactly. Try <%@include file="a.jsp"%> Thanks with <%@include %> it works fine. But is there another solution ? I have several login.jsp that include my page a.jsp... could you confirm me that with <jsp:include /> it doesn't work ? Thanks a lot... > Thanks with <%@include %> it works fine. But is there another solution > ? I have several login.jsp that include my page a.jsp... could you > confirm me that with <jsp:include /> it doesn't work ? Yes, it doesn't work. As I said, check the documentation; it's definitely more reliable than me Another solution might be to forward, but: 1) I see you tried, with no success. The exception you get is fairly strange, by the way, and it might be related to your code. 2) even if you solve the problem, I don't think you can forward to pages outside of your context, so forwarding to another server is probably unfeasible I don't think there is another solution. Not without changing your login pages > Hello, > [quoted text clipped - 5 lines] > a.jsp. I use response.sendRedirect() but it doesnt't worf. Has anybody > got an idea ? What exactly do you mean by "doesn't work"? What happens? Stating versions of apache and tomcat wouldn't hurt either. it executes the rest of my code so login.jsp is displayed.
