JSTL Core tag – out() : Function



The <c:out> tag displays the result of an expression, similar to the way <%= %> works with a difference that <c:out> tag lets you use the simpler “.” notation to access properties. For example, to access customer.address.street just use tag is <c:out value=”customer.address.street”/>.

The <c:out> tag can automatically escape XML tags so they aren’t evaluated as actual tags.

Attribute Description Required Default

escapeXml True if the tag should escape special XML characters No true
