Basically I have a web service connected to a database, that has an insert method.
I’ve created a registration form in a jsp and I need to send data the user inserted in the registration.jsp form to my web service. So I used a web service client invocation as the action to the registration.jsp when clicking the submit button.

I dont know how to get the data the user entered in the form and pass it to the web client who in turn insert it in my web service database.

Here are my codes:

    <html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
      <title> Registration</title>
    </head>
    <body>
        <h1> Welcome</h1>


        <form name="test" action="Wclient2.jsp" method="POST" enctype="multipart/formdata">

                   <table border="0">
                <thead>
                    <tr>
                        <th>Register Here</th>
                      <th></th>
                    </tr>
                </thead>
                <tbody>
                    <tr>
                        <td>First Name:</td>
                        <td><input type="text" name="fname" value="" size="50" /></td>
                    </tr>
                    <tr>
                        <td>Last Name:</td>
                        <td><input type="text" name="lname" value="" size="50" /></td>
                    </tr>
                    <tr>
                        <td>Email:</td>
                        <td><input type="text" name="email" value="" size="50" /></td>
                    </tr>
                    <tr>
                        <td>Password:</td>
                        <td><input type="password" name="password" value="" size="50"/>      </td>
                    </tr>

                    <tr>
                        <td></td>
                        <td> <input type="submit" value="submit" name="submit" /> </td>
                    </tr>
                </tbody>
            </table>

        </form>
    </body>
</html>

And this is the code for the web client upon clicking the submit button of the

registration( action=”Wclient2.jsp” method=”POST”)

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
      <title> Enroll</title>
    </head>
    <body>
        <h1> Welcome</h1>

        <form name="test"<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>

           <%-- start web service invocation --%><hr/>
        <%        

            try {
                mypack.Bioweb_Service service = new mypack.Bioweb_Service();
                mypack.Bioweb port = service.getBiowebPort();
                // TODO initialize WS operation arguments here

                java.lang.String fname = "";
                java.lang.String lname = "";
                java.lang.String email = "";
                java.lang.String password = "";

                // TODO process result here

                java.lang.String result = port.insert(fname, lname, email, password);
                out.println("Result = " + result);

            } catch (Exception ex) {
                // TODO handle custom exceptions here
            }
        %>
        <%-- end web service invocation --%><hr/>

    </body>
</html>

I dont know how to get the parameters for fname from the registration.jsp to put in the web client.
When I write:

java.lang.String fname = request.getParameter(“fname”);

to get the value of textfield fname into my web service, in my database a row is created but NULL is inserted instead of the values my user entered in the form.

Please help.

    I dont see any issue with your client side code(html/jsp) if you use request.getParameter(“fname”) as long you provide input to FirstName. To isolate the issue, print the value of fname in your jsp

    String fname =request.getParameter("fname") ;
System.out.println("Value of first name " +fname) // this will print your console
java.lang.String result = port.insert(fname, lname, email, password);

    If this prints your input correctly, you would need to see service implementation to check it reads and process the input correctly. If it is fname is null , then we can come back to the HTML/JSP to have second look.

    Update:
    To see the request in details, you could use below code 

    Enumeration reqParams= request.getParameterNames();
while (reqParams.hasMoreElements()) {
    String key= (String) reqParams.nextElement();
    String val = request.getParameter(element);
    System.out.println(" Key ==> "+key+" , Value ==> "+val);

}

    Try this and lets see if you get values for any of the input your enterd in your html form.
