How do include a javascript file into JSP?

[Maria Modeste]

I am using the following code to include some java script (- no error messages are being displayed, but it is not working):

<jsp:include page = "validation.js" flush = "true" />

I also placed this in the header tags:
<script language="JavaScript" type="text/JavaScript">
<--

//-->
</script>
As well as in the form tag I placed the usual code:

<form name="claimform1" onSubmit="return Claim(this)" id="claimform1" method="post" action="Claim_Form_2.jsp">


The java script code is saved in a file called "validation.js" Can anyone suggest what else I can do for JSP to recognise the javascript code?
