How to change <fmt:formatDate> pattern dynamically?

How to change <fmt:formatDate> pattern dynamically? I have two patterns for two locales. Also I have the property file for each locale with the date.format key, somewhere its value is MM/dd/YYYY, somewhere DD/MM/YYYY, and so on. In the JSP I have the following tag:

<fmt:formatDate value="${news.creationDate}" pattern="<tag:resource key="date.format"/>"

Where <tag:resource> is my own tag, which gives resources from a property file.

Solution

  • You can't nest tags, but you can assign the value to a variable and pass that along.

    <c:set var="dateFormat"><tag:resource key="date.format" /></c:set>

<fmt:formatDate value="${news.creationDate}" pattern="${dateFormat}" />
