I need the current year as an integer value (e.g. 2015) stored in a variable in a JSP page.
This is the JSTL tags i'm using:
<jsp:useBean id="date" class="java.util.Date" />
<fmt:formatDate var="currentYear" value="${date}" pattern="yyyy" />
<fmt:parseNumber var="currentYear" integerOnly="true" type="number" value="${currentYear}" parseLocale="en-US"/>
And this is the error I'm facing in the Tomcat Log:
[javax.servlet.ServletException: javax.servlet.jsp.JspException: In <parseNumber>, value attribute can not be parsed: "Wed Apr 29 00:42:30 CEST 2015"] with root cause
java.text.ParseException: Unparseable number: "Wed Apr 29 00:42:30 CEST 2015"

at org.apache.jsp.new_.reports_jsp._jspService(reports_jsp.java:136)
Am I doing something wrong?
The strangest thing is that I see this error only in the log: if I load the page, everything works as it should and I see the correct current year.
In the end I used an alternative workaround for my problem:
<jsp:useBean id="date" class="java.util.Date" />
<c:set var="currentYear" value="${date.getYear() + 1900}" />
