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

I have jsp code working fine on one of the machines. But when I copied to another machine, I get that such a method did not find an exception. I am new to spring. Can someone explain what I am missing.

The following are lines of code that throw an 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

Here is a link that looks like a solution to this problem, but I did not understand what they were saying.

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

You need JSTL fn:substring() ,

 <%@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, save 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 correct data type for the data it holds.

You can also do the following.

  <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
