Random taglib ver. 1.7

Custom JSP tags library. Tag randomValue calculates an integer random value within the given interval. Two parameters are integer values describe interval. You may use this tag in two forms:

1) just prints the random value

<%@ taglib uri="taglib.tld" prefix="rand" %>
<html>
<p><i> Random value within the interval [1,10]:</i> <rand:randomValue from="1" to="10"/>
</html>

2) prints nothing, but creates a variable (type is java.lang.Integer) initialized by the random value from the given interval. You may use this variable later in your scriptlets:

<%@ taglib uri="taglib.tld" prefix="rand" %>
<html>
<rand:randomValue from="5" to="9" id="var_name"/>
<br>Random is <%=var_name.intValue()%>
<%
int val=var_name.intValue();
....
%>
</html>

Parameter id describes a name for this variable. E.g. in the above mentioned example this name is var_name.

Tag randomSequence calculates an sequence of random numbers within the given interval. Tag also creates a page (session, application) scope variable (type is java.util.ArrayList) for the calculated values.
