[opencms-dev] Strange error using string methods

[lk]

Hi,

I need to manage some date that I get from a news module.

I want to convert the date (a string I get from the request) to a 
Calendar object.
The code I'm using is (Opencms 6.2):

<c:set var="dateString">
	<cms:contentshow element="Date" />
</c:set>
<%
	cms.setDate("dateString");
%>
<%
String myDate = (String)request.getAttribute("dateString");
out.println("<br>dataStringa: " + dataStringa + "<br>");
out.println(" LUNGHEZZA STRINGA " + dataStringa.length() + "<br>"); 
//this line causes an error
long longNumber = Long.parseLong(dataStringa);
//this line causes an error
java.util.Calendar tempDay = java.util.Calendar.getInstance();
tempDay.setTimeInMillis(longNumber);

The errors are like:
"Error An unexpected error happened, but no error message has been provided.
Please check the error details or contact your system administrator. "

And the complete exception is:

java.lang.NullPointerException
