Hi, This is my first post to ask a question on stack overflow and my issue is that when I don't see a client side validation error message when I don't enter any values for that field even when it is configured as required. The input page is reloaded but no error message is seen. I am not sure what I am doing wrong. Any advice would be greatly appreciated. My scenario is given below:
I have a simple form where I have a pull down menu called selection criterion. A value must be selected. If a value is not selected, then the page should reload with configured error message. My input form action_item_search.jsp is given below:
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Action Item Search</title>
</head>
<body>
<s:actionerror/>
<s:fielderror />
<s:form action="action_item_search" validate="true">
<s:select label="Search Criterion" name="searchCriterion"
list="#{'': 'Select One', 'creatorName':'creator name',
assignedTo':'assigned to'}" required="true" />
<s:submit name="search" value="Search"></s:submit>
</s:form>
</body>
I have add validators.xml in my WEB-INF/classes directory of exploded war file as given below:
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator Config 1.0//EN"
"http://www.opensymphony.com/xwork/xwork-validator-config-1.0.dtd">
ActionItemTrackingAction-findByCriteria-validation.xml is given below:
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator 1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
You must enter a search criterion.
My struts mapping xml:
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<!-- <include file="example.xml"/> -->
<package name="action-item" extends="struts-default">
<action name = "action_item_search_input">
<result name = "success">/action-item-search.jsp</result>
</action>
<action name="action_item_search" class="gov.nasa.spacebook.ActionItemTrackingAction" method="fetchByCriteria">
<result name = "success">/action-item-result.jsp</result>
<result name = "input">/action-item-search.jsp</result>
<result name = "error">/action-item-search.jsp</result>
</action>
</package>
My action class
public class ActionItemTrackingAction extends ActionSupport {
private List<ActionItem> actionItems;
public List<ActionItemTracking> getActionItems() {
return actionItems;
}
public void setActionItems(List<ActionItemTracking> actionItems) {
this.actionItems = actionItems;
}
private String searchCriterion;
public String getSearchCriterion() {
return searchCriterion;
}
public void setSearchCriterion(final String criterion) {
this.searchCriterion = criterion;
}
public String fetchByCriteria() throws Exception {
final ActionItemTrackingService service =
new ActionItemTrackingService();
this.actionItems = service.getByField(this.actionItem);
return super.execute();
}
}
