Choose taglib ver. 1.3

    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>
