Custom JSP taglib. Provides a custom tags based replacement
for a chain of if operators in your scriptlets. For example, in scriptlet you
may have some like this:
<% if (cond1) { some code ... } else if (cond2) { some code ... } else { some code ... } %> Now taglib lets you write some like this:
<%@ taglib uri="taglib.tld" prefix="if" %> <if:choose> <if:when cond="cond1_expr"> some code </if:when> <if:when cond="cond2_expr"> some code </if:when> <if:otherwise> some code </if:otherwise> </if:choose> For example:
<%@ taglib uri="taglib.tld" prefix="if" %> <% String s=request.getParameter("field"); %> <if:choose> <if:when cond="<%=s==null%>"> some code </if:when> <if:when cond="<%=s.equals(\"1\")%>"> some code </if:when> <if:otherwise> some code </if:otherwise> </if:choose> Tags are: choose Describes a set of conditionally executed blocks when and otherwise.
