Example

<fmt:message key="result">
  <fmt:param value="${result.total}" />
  <fmt:param value="${result.percentage}" />
</fmt:message>

The <fmt:param> action is used as a nested action for <fmt:message> to supply a parameter value for a parameterized message.

The parameter syntax that can be used in the parameterized message is the syntax accepted by the java.text.MessageFormat class, i.e., a 0-based order number optionally followed by a data type name and a format specification, within curly brackets:

{orderNumber [, dataType [, format ]]}

The data type must be one of time, date, number, or choice.

For a time or date type, the format specification can be one of short, medium, long, full, or the type of customized pattern described for <fmt:formatDate>.

For a number type, the format specification can be currency, percent, integer, or the type of customized pattern described for <fmt:formatNumber>.
