I am doing a project for a class of HS teachers in July, to teach them the wonders of Java and NetBeans. I designed a set of servlets to let them manage student grades. I am having them design the basic HTML in NVU, and put it into the try blocks of the NB-generated processRequest servlets, and then put it into out.println("..."); blocks. I am using Tomct.
I would use JSF myself, but I have no time to get into that, so I am using forms and submit buttons to do the navigation. So the first test is to see if the navigation works with the static HTML servlet pages. When that works, I will put in the database queries. But the navigation is not working for me. I changed the Project (classdata) Run property in NB to point to login. Here is the processRequest login code: response.setContentType("text/html;charset=UTF-8"); PrintWriter out = response.getWriter(); try { out.println("<html>"); out.println("<head>"); out.println("<title>Servlet login</title>"); out.println("</head>"); out.println("<body>"); out.println("<h1 style=\"color: rgb(0, 102, 0);\">" +"Student Grade Manager Login</h1>" + "<form method=\"post\" action=\"dataSelection\" name=\"login\">"); out.println("<h3>User Name: <input maxlength=\"40\" size=\"40\"" + "name=\"name\"></h3><br>"); out.println("<h3>Password: <input maxlength=\"40\" size=\"40\"" + "name=\"password\" type=\"password\"></h3>" + "<input name=\"Login\" value=\"Login\" type=\"submit\"><br>"); out.println("</body>"); out.println("</html>"); } finally { out.flush(); } This displays, the debugger and html inspector show that it indeed calls the servlet at classdata/dataSelection. Its processRequst code is: response.setContentType("text/html;charset=UTF-8"); PrintWriter out = response.getWriter(); try { out.println("<html>"); out.println("<head>"); out.println("<title>Servlet dataSelection</title>"); out.println("</head>"); out.println("<body>"); out.println( "<h1 style=\"color: rgb(0, 102, 0);\">Student Grade Data</h1>"); out.println("<hr style=\"width: 100%; height: 2px;\">"); out.println( "<form method=\"post\" action=\"studentData\" name=\"User Choice\">"); out.println("<h2>Student Data</h2>"); out.println("<h3>Student Name:<input text=\"\" name=\"studentName\"" + " type=\"\"></h3>"); out.println("<input name=\"nameSubmit\" value=\"Submit Name\"" + " type=\"submit\">"); out.println("</form>"); out.println("<hr style=\"width: 100%; height: 2px;\">"); out.println("<h2>Class Data</h2>"); out.println( "<form method=\"post\" action=\"classData\" name=\"classData\">" + " <input name=\"classData\" value=\"Get Class Data\"" + " type=\"submit\"></form>"); out.println("<hr style=\"width: 100%; height: 2px;\">"); out.println("<form method=\"post\" action=\"logout\"" + " name=\"Student Logout\"><input name=\"logout\"" + " value=\"Logout\" type=\"submit\"><br></form>"); out.println("</body>"); out.println("</html>"); } finally { out.flush(); } But nothing displays! The login screen remains displayed. The browser page source is blank. And an initial navigation to the dataSelection URL is also blank. What am I missing???? Here is web.xml: <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>login</servlet-name> <servlet-class>ARC08.login</servlet-class> </servlet> <servlet> <servlet-name>logout</servlet-name> <servlet-class>ARC08.logout</servlet-class> </servlet> <servlet> <servlet-name>classData</servlet-name> <servlet-class>ARC08.classData</servlet-class> </servlet> <servlet> <servlet-name>studentData</servlet-name> <servlet-class>ARC08.studentData</servlet-class> </servlet> <servlet> <servlet-name>dataSelection</servlet-name> <servlet-class>ARC08.dataSelection</servlet-class> </servlet> <servlet-mapping> <servlet-name>login</servlet-name> <url-pattern>/login</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>logout</servlet-name> <url-pattern>/logout</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>classData</servlet-name> <url-pattern>/classData</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>studentData</servlet-name> <url-pattern>/studentData</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>dataSelection</servlet-name> <url-pattern>/dataSelection</url-pattern> </servlet-mapping> <session-config> <session-timeout> 30 </session-timeout> </session-config> </web-app> There is nothing in the Tomcat log file, but the NetBeans console shows Tomcat starting up OK.
