I am using Struts 2 with the XML based validation and it is throwing the
following exception:
info: CORE3282: stdout: ERROR - ValidatorFactory.parseValidators(335) |
Unable to load file:C:/Projects/test/webapps/default/WEB-INF/classes

r.java:252)
........ (continues listing Struts classes without any further error
messages)
I examined the code of ValidatorFactory.parseValidators and line 326 seems
to be throwing the exception:
318 List<File> files = new ArrayList<File>();
319 try {
320 Iterator<URL> urls = ClassLoaderUtil.getResources("",
ValidatorFactory.class, false);
321 while (urls.hasNext()) {
322 URL u = urls.next();
323 try {
324 URI uri = new URI(u.toExternalForm().replaceAll("
", "%20"));
325 if ("file".equalsIgnoreCase(uri.getScheme())) {
326 File f = new File(uri);
327 FilenameFilter filter = new FilenameFilter() {
328 public boolean accept(File file, String
fileName) {
329 return
fileName.contains("-validators.xml");
330 }
331 };
332
files.addAll(Arrays.asList(f.listFiles(filter)));
333 }
334 } catch (Exception ex) {
335 LOG.error("Unable to load " + u.toString(), ex);
Code Located at:
http://svn.opensymphony.com/fisheye/browse/xwork/branches/2.0/src/java/com/opensymphony/xwork2/validator/ValidatorFactory.java?r=1850
Does anyone have any suggestions about what I can do to make the URL
hierarchial so that the validator doesn't throw this exception? The path
provided in the stack trace does point to the location where my Java class
files and my Form-validation.xml file is located. Any suggestions would be
appreciated.
Thanks!!
Note: I also included my struts config files below in case there is anything
useful in them.
My Form-validation.xml file (located in
C:/Projects/test/webapps/default/WEB-INF/classes/org/web):
<!DOCTYPE validators PUBLIC "-//OpenSymphony Group//XWork Validator
1.0.2//EN"
"http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd";>
<validators>
<field name="name">
<field-validator type="required">
<message>The user name field is required!</message>
</field-validator>
</field>
</validators>
My form.jsp page:
<%@ page language="java" %>
<%@ taglib uri="/struts-tags" prefix="s" %>
<html>
<body>
<form action="Form" theme="simple">
<p>
Please enter your name: <input type="text" name="name" /><br />
<s:fielderror />
<s:actionerror />
<input type="submit" value="submit" />
</p>
</form>
</body>
</html>
My Struts action code:
package org.web;
import com.opensymphony.xwork2.ActionSupport;
public class Form extends ActionSupport {
public String name;
public String execute() {
return "success";
}
public getName() {
return name;
}
public setName(String name) {
this.name = name;
}
My Struts.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd";>
<struts>
<package name="default" namespace="/" extends="struts-default">
<action name="Form" class="org.web.Form">
<result name="success">success.jsp</result>
<result name="input">form.jsp</result>
</action>
</struts>
