  • You are using wrong name with input tag in your JSP, please verify those. For example there is nothing called Orgname in your JSP. that's why you are getting null for that. Commented Jun 29, 2017 at 11:27
  • You will find a complete explanation about HTML form on mozilla documentation Commented Jun 29, 2017 at 11:33
  • Lina, just for letting you know, you cannot accept two answers for one question here. Only one answer per question is allowed. Commented Jun 29, 2017 at 11:54

In Servlet you need to get parameters by name attribute, not id.

For example, You have the following,

<input id="Orgname" name="name" placeholder="Organization name" required="" tabindex="5" type="text">

Here you have given id to be Orgname and name parameter is name. So in Servlet you will do,

request.getParameter("name");

But you are doing,

String Orgname = request.getParameter("Orgname");

Secondly, you cannot have same name for two parameters. For both the following you have given name to be name

<input id="Orgname" name="name" placeholder="Organization name" required="" tabindex="5" type="text"> <input id="address" name="name" placeholder="Street,Area,city" required="" tabindex="6" type="text"> <br>

Give some different name to the parameters.

The getParameter function of request object works with name attribute. So please replace your jsp with following.

<form id="contactform" action="servlet/SaveInfo" method="post"> <p class="contact"><label for="email">Email</label></p> <input id="email" name="email" placeholder="[email protected]" required="" tabindex="1" type="email"> <p class="contact"><label for="username">User Name</label></p> <input id="username" name="username" placeholder="username" required="" tabindex="2" type="text"> <p class="contact"><label for="password">Password</label></p> <input type="password" id="password" name="password" required="" tabindex="3"> <p class="contact"><label for="repassword">Confirm Password</label></p> <input type="password" id="repassword" name="repassword" required=""> <p class="contact"><label for="phone">Mobile Phone</label></p> <input id="phone" name="phone" placeholder="phone number" required="" tabindex="4" type="text"> <br> <p class="contact"><label for="name">Organization Name</label></p> <input id="Orgname" name="Orgname" placeholder="Organization name" required="" tabindex="5" type="text"> <p class="contact"><label for="Address">Address</label></p> <input id="address" name="address" placeholder="Street,Area,city" required="" tabindex="6" type="text"> <br> <!-- <select class="select-style" name="BirthMonth"> --> <label>State</label><br> <select class="select-style" name="BirthMonth"> <% ResultSet rs = null; Connection con = null; PreparedStatement pmst1= null; int countryid = 208; try{ con = DBConnectivity.getOracleDBConnection(); pmst1 = con.prepareStatement(Sqlquery.getRegion()); pmst1.setInt(1, countryid); rs=pmst1.executeQuery(); while(rs.next()){ String name = rs.getString("name"); %> <option value="<%=name %>"><%=name %></option> <% } %> <% }catch(Exception e){ } %> </select><br><br> <p class="contact"> <input id="check" name="name" style="margin-right: 10px" type="checkbox"> <label for="name"> Not Yet Registered GSTIN</label> </p> <p class= "GSTIN"><label for="GSTIN">GSTIN No.</label></p><br> <input id = "GSTINNO" maxlength="15" name= "GSTIN" placeholder="GSTIN No." type ="text"><br><br> <input class="buttom" name="submit" id="submit" tabindex="5" value="Sign me up!" type="submit">

JSP post parameters using their attribute name. you wrote the wrong attribute name in 3 parameters.

Change:

<input id="check" name="name" <input id="Orgname" name="name" <input id="address" name="name"

To:

<input id="check" name="check" <input id="Orgname" name="Orgname" <input id="address" name="address"
