Hi malak,
Try this code :
<% String ipaddress = request.getParameter("ipaddress"); %>
<form method="POST" action="add.jsp">
<table border="0" cellpadding="4" width="90%">
<tr>
<td valign="top" bgcolor="#AFD0D1" color="red">
<font size="1" face="arial,helvetica"><b>Please add a new
entry, don't leave any field empty</b></font>
</td>
</tr>
<tr>
<td valign="top" bgcolor="#FFCC66"><font size="2"
face="Verdana"><b></b></font></td>
</tr>
<tr>
<%=ipaddress%>
<td valign="top" bgcolor="#CCCCCC">
<font size="2" face="arial,helvetica">
<% if (ipaddress.length() == 0) { %>
<input type="text" size="45" name="ipaddress">IP Address<br>
<% } else { %>
<input type="text" style="background-color: #ffcccc"
size="45" name="ipaddress" value=<%=ipaddress%>>Reenter IP Address<br>
<% } %>
</tr>
</table>
</form>
I hope this is what you want.

Objet : simple question please
HI, I have a form, I want if this form is not processed, the fields
missing change the color ( this is done using style html), but I don't
know why the other fields entered have gone, here is the form :
<form method="POST" action="add.jsp">
<table border="0" cellpadding="4" width="90%">
<tr>
<td valign="top" bgcolor="#AFD0D1" color="red"><font size="1"
face="arial,helvetica"><b>Please add a new entry, don't leave any field
empty</b></font></td>
</tr>
<tr>
<td valign="top" bgcolor="#FFCC66"><font size="2"
face="Verdana"><b></b></font></td>
</tr>
<tr>
<%=request.getParameter("ipaddress")%>
<td valign="top" bgcolor="#CCCCCC">
<font size="2" face="arial,helvetica">
<% if (!("".equals(ipaddress))) { %>
<input type="text" size="45" name="ipaddress">IP Address<br>
<% } else { %>
<input type="text" style="background-color: #ffcccc" size="45"
name="ipaddress" value=<%=request.getParameter("ipaddress")%>>Reenter IP
Address<br> <% } %> .... </form>
My question why this line <%=request.getParameter("ipaddress")%>
works, and this :
<input type="text" style="background-color: #ffcccc" size="45"
name="ipaddress" value=<%=request.getParameter("ipaddress")%>>Reenter IP
Address<br> does not
Thanks
