Recently in an old system of upgrading the company, the old system of 05. The System JSP page does not use the Struts2 label <s:if>, but uses the <C:IF> The problem comes,<c:if> there is no else statement!!

The following methods can be used to solve this problem.

Use the general form of <c:if>, i.e. when else is not required:

<%@ taglib uri= "/web-inf/c.tld" prefix= "C"%><!--ellipsis-<c:if> <!--IF---</c:if>

<c:if> no <c:else> When you need to use else, we can replace the structure with <c:choose>:

<%@ taglib uri= "/web-inf/c.tld" prefix= "C"%><!--ellipsis-<c:choose> <c:when test= "" > <! ---</c:when> <c:otherwise> <!--otherwise--</c:otherwise> </c:choose >

<c:if> No <c:else> solution
