hi,
Im developing web based project using jsp and rest api with java.
I'm using netbeans 8.0.2 IDE and apache-tomcat-8.5.0.

this is my main jsp page:


<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <form class="customform" action="/user/GUI/insert.jsp">
            username:
            <input type="text" name="username" value="" />
            <input type="submit" value="submit" name="submit" />
        </form>
    </body>
</html>


then insert.jsp page in GUI folder:

<%@page import="entity.User"%>
<%@page import="presentation.calls"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@page import="java.util.ArrayList"%>
<%@page import="java.util.Map.Entry"%>
<%@page import="java.util.Set"%>
<%@ page import = "java.util.Map" %>
<jsp:useBean id="sample" scope="page" class="presentation.calls" />


<%
   
    calls obj = new calls();
    User use = new User(request.getParameter("username"));
    System.out.println("-------------------------------------------starting!------");
    use.setUsername(request.getParameter("username"));
    obj.insertData(use);
    System.out.println("------data goes--------------");
%>



then calls.java class in presentation package:


finally this is the insertData method in UserFacadeREST_JerseyClient.java class:



//this is automaticall generated bu rest client.



There are no any erors occur in the project and server also run well.
when i run the project this first appear :




but after enter a name and sumit ,it shows this ERROR:

HTTP Status 500 - An exception occurred processing JSP page /GUI/insert.jsp at line 23

Remove java code from jsp page, it's a very old practice.  You should ideally have a servlet for this purpose.  As far as the error is concerned, you seem to have some issues with insertData method.
