Configurable Errors

[James Dekker]

Hello there,

I am creating a configurable errors file which gets loaded as a
properties file from an init servlet:

import java.io.IOException;
import java.util.Properties;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;

public class ErrorInitServlet extends HttpServlet {

       static Properties errorProps = new Properties();

       public void init() throws ServletException {
           Properties props = new Properties();
           try {
               props.load(this.getClass().getClassLoader().getResourceAsStream(
                       "/error.properties"));
           }
           catch (IOException e) {
               e.printStackTrace();
           }
       }

      public static Properties getErrorProperties() {
                return errorProps;
        }
}

The error.properties file looks like this:

error.required.field=Required %s
error.invalid.entry=Invalid %s
error.unknown.entry=Unknown %s

I created an ActionErrors.java file:

package org.coffeebreak.wrapper;

import java.util.Formatter;
import java.util.ResourceBundle;

/**
* @author jdekker
*/
public class ActionError {

   private final ResourceBundle m_resource;

   public ActionError() {
         m_resource = ResourceBundle.getBundle("error.properties");
   }

   public String getMessage(String id, Object... parameters) {
       String value = m_resource.getString(id);
       if (null != value) {
           StringBuilder builder = new StringBuilder();
           Formatter f = new Formatter(builder);
           f.format(value, parameters);
           f.flush();
           return builder.toString();
       }
       return value;
   }
}

I had my ant build script move the error.properties to:
TOMCAT_HOME/WEB-INF/classes/org/coffeebreak/wrapper/

Now, when I invoke this class, through a client, this is the error that I get:

        at 
org.coffeebreak.views.EditUserPane.actionPerformed(EditUserPane.java:141)

Why is ActionError having trouble finding the error.properties file?
Is there a way to use my InitServlet's getter to set the resource
bundle? Am I going about this the wrong way?

Sincerely,

James
