My servlet doesn't get params

[moshi cochem]

Hi.
I try to call a servlet and to pass parameters to it. My form is very simple:
<form action="HelloWorld" method="get">
<table>
<tr>
<td><label>name</label></td>
<td><input type="text" id="txtName"></input></td>
</tr>
<tr>
<td><label>family</label></td>
<td><input type="text" id="txtfamily"></input></td>
</tr>
</table>

<input type="submit"></input>
</form>

And in my servlet I have inside the doGet method:
String name = request.getParameter("name");
That gets null.

I tried also to add a method of doPost, and to write the same code in it, but I still get NULL.

Any idea ?
Thanks.

Please UseCodeTags.

You're missing the "name" attributes of the <input> tags - a "label" is something different.

Your results should be no surprise because you don't have an input element with the name name. When you ask for the value of a request parameter that doesn't exist, you get null.

P.S. You ought to avoid using tables for formatting.

Ya As Bear and Ulf said , there is nothing named "name" as you mentioned in your code to get the value of it , your code must looks like this :

 <input type="text" id="txtName" name="SomeName"></input>  

String name = request.getParameter("SomeName");

 

Hope this is helpful ..

Hi,
thanks for all the replies.
So I understand that the request object works with name and not with id, right ?
I'll try it.
And another thing, why should't I use tables ? Should I use DIV instead ? I'll be glad to hear why.
Thanks a lot!

There is no relation with table/DIV with servlet. You can use DIV also...

The choice between the table and div would come as part of a choice for the design of the web.

div would call for some use of styling on your part where as table can be used to layout as effectively. Also, for form parameters, name would be the obvious, and I think the only, choice. The id attribute would be used for identifying it as part of the DOM, if i am not wrong.

Using tables for formatting is a pre-CSS dinosaur. Use CSS for layout, tables for tables.
