JSP/JSTL using or not using <c:out> tags

i'm helping develop a java jsp jstl based web service and all dynamic objects are being inserted using ${object.foo} and i was wondering if it made a difference whether or not it was actually in <c:out value="${object.foo} />?

the pages all load correctly, but i wonder if there is something that i'm not seeing that may be an issue.

Use EL expressions, and if you need output escaping then use the fn:escapeXml function like ${fn:escapeXml(myText)}.

when you use JSTL core out tag, you have some more options:

  • The values that you are passing to the tag will be by default XML-escaped
  • You can provide a default value which will be displayed if the value passed is null.

In previous versions of jsp it was not possible to directly use el expressions in text content, you had to use c:out. This is no longer neccessary, using el expressions directly for output creates a much less cluttered jsp in my opinion. The c:out tag still has its uses if you need to control output escaping via the escapeXml attribute.
