java.lang.NoSuchMethodException: java.lang.String.substring(java.lang.Long, java.lang.Long)

Question

I have a jsp code working fine on one of the machines. But when i copied to another machine I am getting this no such method found exception. I am new to spring. Can some one explain what am i missing.

Following is the lines of code that is causing exception:

<c:set var="rawDate" value="${result.getDate()}"/>
<c:set var="rawTime" value="${result.getTime()}"/>
<td id="formattedDate" class="center"><c:out value="${rawDate.substring(4,6)}"/>/<c:out value="${rawDate.substring(6,8)}"/></td>
<td id="formattedTime" class="center"><c:out value="${result.getTime().substring(0,2)}"/>:<c:out value="${result.getTime().substring(2,4)}"/></td>

Here is the stack trace

Answer 1

EL (Expression Language, those ${} things) treats numbers as long while the real method expects int numbers only. That explains this exception.

You need JSTL fn:substring() instead,

<%@taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions" %>
...
<c:set var="rawDate" value="${result.date}"/>
<c:set var="rawTime" value="${result.time}"/>
<c:out value="${fn:substring(rawDate,4,6)}"/>/<c:out value="${fn:substring(rawDate,6,8)}"/>
<c:out value="${fn:substring(rawtime,0,2)}"/>:<c:out value="${fn:substring(rawtime,2,4)}"/>

or better, just use the right tool directly, store it as java.util.Date in the model and use JSTL <fmt:formatDate>.

<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
...
<fmt:formatDate value="${result.realJavaUtilDate}" pattern="MM/dd HH:mm" />

Use the right data type for the data it holds.

Answer 2

You can do the following thing also.

    <c:set var="rawDate" value="${result.getDate()}"/>
    <c:set var="rawTime" value="${result.getTime()}"/>
    <td id="formattedDate" class="center"><c:out value="${rawDate.substring(Integer.parseInt(\"4\"), Integer.parseInt(\"6\")}"/>/<c:out value="${rawDate.substring(Integer.parseInt(\"6\"), Integer.parseInt(\"8\")}"/></td>
    <td id="formattedTime" class="center"><c:out value="${result.getTime().substring(Integer.parseInt(\"0\"), Integer.parseInt(\"2\")}"/>:<c:out value="${result.getTime().substring(Integer.parseInt(\"2\"), Integer.parseInt(\"4\")}"/></td
