can we put HTML input tag with in <form:form> </form:form>?

[Abhra Kar]

<form:form name="form1" commandName="user1">
First Name:
<input type="text" name="fname" id="fname" />

Last Name:
<input type="text" name="lname" id="lname" />

<input type="button" value="click here" onclick="myfunc()" />
</form:form>

Is this gives any error?
I am using this because I need the id attribute here
thanks in advance
