I have such custom JSP tag file: /WEB-INF/tags/formField.tag -------------------------------------------------------------- <%@ taglib prefix="s" uri="/struts-tags" %>
<%@ tag language="java" pageEncoding="UTF-8" %> <%@ attribute name="fieldName" %> <%@ attribute name="inputId" %> <%@ attribute name="label" %> <%@ attribute name="labelKey" %> <%@ attribute name="required" %> <s:set var="inputId" value="%{#attr.inputId != null ? #attr.inputId : (#attr.fieldName != null ? #attr.fieldName : '')}"/> <s:set var="label" value="%{#attr.labelKey != null ? getText(#attr.labelKey) : (#attr.label != null ? #attr.label : '')}"/> <s:set var="fieldErrors" value="%{fieldErrors[#attr.fieldName]}"/> <s:set var="hasFieldErrors" value="%{#fieldErrors != null && #fieldErrors.size > 0}"/> <div class="wwgrp <s:property value="%{#hasFieldErrors ? 'HasFieldErrors' : ''}"/>"> <table class="HiddenTable"> <tr> <td class="wwlbl"> <s:if test="%{!isBlank(#label)}"> <label class="label" for="<s:property value="%{#inputId}"/>"> <s:if test="%{#attr.required}">*</s:if> <s:property value="%{#label}" escape="false"/>:</label> </s:if> </td> <td class="wwctrl"> <jsp:doBody/> <s:if test="%{#hasFieldErrors}"> <ul class="wwerr"> <s:iterator var="error" value="%{#fieldErrors}"> <li class="errorMessage"> <s:property value="%{#error}" escape="false"/></li> </s:iterator> </ul> </s:if> </td> </tr> </table> </div> -------------------------------------------------------------- And here is the part of my "login.jsp" that uses this custom tag: -------------------------------------------------------------- <%@ taglib prefix="t" tagdir="/WEB-INF/tags" %> ... <s:form action="login"> ... <t:formField fieldName="password" required="true" labelKey="msgkey.label.password"> <input type="password" id="password" name="password"/> TODO: Forgot your password? </t:formField> ... </s:form> -------------------------------------------------------------- Suppose action has a property 'fieldName' and I need to get value of a tag attribute w/ the same name. I get tag atribute using <s:property value="%{#attr.fieldName}"/>. The issue here is: if jsp page that uses this custom tag does not provide value for 'fieldName' attribute, then <s:property value="%{#attr.fieldName}"/> will return value of action property 'fieldName'. I did not found where jsp tag stored its attribute, but it seemed like in PageContext. I tried to get PageContext, but ActionContext returns 'null'. Here is my Java code: PageContext pageContext = ServletActionContext.getPageContext(); if (pageContext != null) { log.debug("pageContext.findAttribute('fieldName'): " + pageContext.findAttribute("fieldName")); } Musachy Barroso wrote: > > I am not sure I understand what you mean.
