    "Undefined" error when trying to read array from external JavaScript file

    HI all,

    I tried to read an array from an external javascript file called read.js,The array was declared & as well as defined with some values inside the <script> tag of a html file.

    For an instance:
    test.html:
    --------------
    <html>
    <head>
    <script>
    var a=new Array(1,2,3);
    </script>
    <script type="text/javascript" src="read.js"></script>
    </head>
    </html>

    read.js:
    ----------
    a.sort();
    alert(a[0]);

    test.jsp:
    --------------
    <html>
    <head>
    <script>
    var a=new Array(1,2,3);
    </script>
    <script type="text/javascript" src="read.js"></script>
    </head>
    </html>

    This was successful.
    But i am getting "undefined " as result when i tried test.html as test.jsp.
    I am getting "undefined" message only when i tend to create array
    "var a=new Array(1,2,3)" inside the <script>tag of test.jsp,But i did nt get any "undefined" message if i try the same thing with test.html.

    I am getting problem while running this code at server side.

    can u people guide me in resolving this problem???

    Thanks in advance,
    sundar

          hmmm .....
          Code:
          <script type="text/javascript">
var a=new Array(1,2,3);
</script>
          And use "<%@page contentType = "text/html;charset=ut f-8"%>" in ".jsp" at the top.
