JSP Calling Java Method error

I have a JSP page that calls a Java method .. using GlassFish 4.0 it worked just fine, now I'm trying to run it on a new server with Tomcat 6.0 but it keeps giving me this error:
"the function result must be used with a prefix when a default namespace is not specified"

Here's my JSP page:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
......
<jsp:useBean id="diskUtilData" scope="request" class="newpackage.ResultPage" />
.....
<c:forEach var="celldata" items="${diskUtilData.result()}">
<tr>
<c:forEach var="col" items="${celldata}">
<td>
<cut value="${col}" />
</td>
</c:forEach>
</tr>
</c:forEach>
-------------------------------------------------------------------------------

Here's my java method:


package newpackage;

public class ResultPage {

public String[][] result() throws FileNotFoundException, IOException{

String[][] res= new String [60][6];

//Some Code

return res;
}

/////////////////////

Folders:
NetBeansProjects\JSP\web\WEB-INF/lib/jstl-1.2.jar
NetBeansProjects\JSP\web\WEB-INF/lib/standard-1.1.2.jar

Netbeans IDE 7.0

<c:out value="${fn:diskUtilData.length()}" />

*the line turns to red telling me :

"Encountered ":" at line 1,col 4 was expecting one of : "......." "
