As can be seen in the example, report expressions can be assigned to a variable by
using the
<variable>
element in a JRXML file. We give the variable a name, by
using the
name
attribute of the
<variable>
field. The actual expression we want to
assign to a variable must be enclosed inside a
<variableExpression>
