Avoiding multiple validation messages
I am using client-side and server-side validation in my login form.
Both work and when I dont enter the required fields I recieve a javascript
alert box saying that the fields "username or password are required". After
I click okay it does a serverside validation as well and prints on the
screen that the "username or password are required"..
I was wondering if its possible to show "username or password are required"
only once. When there is javascript enabled on the browser, to show the
client side version only and when javascript is disabled use the serverside
version?

Wait a minute! the <c:url> tag produces the URL itself, not the <a>
tag! So, the URL must not be escaped, but, when put into a <a> it
should. As I wrote in my previous post, he should use the "escapeXml"
EL function.

No, Marcello is right. If you're using some minimum version of HTML or
any version of XHTML, the URLs must use & instead of bare & symbols
in URLs. It's the browser's job to send the URL with bare & symbols to
the server, but the HTML source should have them encoded.
Marcello, is there any configuration for the c:url tag (or possibly the
c:html tag?) that allows you to set a flag like "xhtml" or something
similar?

I am not sure if the DTD declares that (I did not take a look at it), but
basically the way to pass param on a HTML URL is the way it was generated -
Every single HTTP server will not parse the parameters correctly if it is in
the form that you want. If you have some special parser or that is indeed
what you want, I guess you will have to pass the entire parameter as one,
and not have multiple parameter arguments on the c:url.

The URL itself is OK, but it needs to be encoded.

URL parameters separator
Posted by Marcello Savino <Ma...@aldebra.com>.
In my jsp i've a code like this:
<logic:iterate id="index" name="list" type="myList">
<c:url value="/myAction.do" var="url1">
<c:param name="id"><bean:write name="index" property="id" /></c:param>
<c:param name="year"><bean:write name="index" property="year"
/></c:param>
</c:url>
<logic:iterate>
The code works good. But the generated url are in this form:
http://localhost:8080/myApp/myAction.do?id=161298&year=2005
Instead of
http://localhost:8080/myApp/myAction.do?id=161298&year=2005
As required by the DTD declared (xhtml 1.0 strict)
Does anybody have some idea to get the right url parameter separator
(&->&) ?
Thanks in advance.

Let me clarify, in your html:form statement, try adding a return like so:
<html:form action="/login" method="post" onsubmit="return
validateLoginForm(this)">

Re: Avoiding multiple validation messages

In your form's onclick="validate()" method (or whatever it may be
called in your case), it may work to add "return" to the javascript
method call. The validate method will return false if validation
fails, and the form will not be submitted back to the server.
