I want to create a servlet project.
My Java class is called AzpanaServlet.java and it contains an inner class. (When I compile it, I have 2 class files).
My project is a simple application that receives string input and does some things with it (it doesn't matter).
When I click the submit button, I get the following error:
HTTP Status 404 - /AzpanaServlet Type Status report Message /AzpanaServlet Description The requested resource (/AzpanaServlet) is not available. Apache Tomcat/6.0.18
Please help me if you can, I can’t solve this a lot of time. this is my java code:
public class AzpanaServlet extends HttpServlet { // //Some functions // //Inner class: public class oneChar{...} // protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { /* * Get the value of form parameter */ String name = request.getParameter("name"); /* * Set the content type(MIME Type) of the response. */ response.setContentType("text/html"); String str = ""; PrintWriter out = response.getWriter(); ArrayList<Integer> list = new ArrayList<Integer>(); try { list = mainmanu(name); //not relevant function. } catch (Exception e) { str = e.toString(); e.printStackTrace(); } /* * Write the HTML to the response */ out.println("<html>"); out.println("<head>"); out.println("<title> this is your answers</title>"); out.println("</head>"); out.println("<body>"); if(str != ""){ out.println(str); } else{ for(int i = 0;i<=40;i++){ out.println(list.get(i)); out.println("<br>"); } } out.println("<a href='form.html'>"+"Click here to go back to input page "+"</a>"); out.println("</body>"); out.println("</html>"); out.close(); } public void destroy() { } }
My web.xml code:
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <servlet> <servlet-name>AzpanaServlet</servlet-name> <servlet-class>com.example.AzpanaServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>AzpanaServlet</servlet-name> <url-pattern>/AzpanaServlet</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/form.html</welcome-file> </welcome-file-list> </web-app>
My form.html code:
<html> <head> <title>Zeev Project</title> </head> <body> <h1>Just Enter String</h1> <form method="POST" action="AzpanaServlet"> <label for="name">Enter String</label> <input type="text" id="name" name="name"/><br><br> <input type="submit" value="Submit Form"/> <input type="reset" value="Reset Form"/> </form> </body> </html>
The folder hierarchy is as follows:
ROOT[ WEB-INF[ web.xml classes[ com[ example[ AzpanaServlet.class AzpanaServlet$oneChar.class ] ] ] lib[ AzpanaServlet.java ] ] META-INF[ MANIFEST.MF ] form.html ]
