JSTL allows developers to write custom iteration tags by implementing the LoopTag interface. This is not to be confused with javax.servlet.jsp.tagext.IterationTag as defined in JSP 1.2. LoopTag establishes a mechanism for iteration tags to be recognized and for type-safe implicit collaboration with custom subtags.
In most cases, it will not be necessary to implement this interface manually, for a base support class (LoopTagSupport) is provided to facilitate implementation.
