Configurable Errors
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:
INFO: Deploying web application archive coffeebreak.war

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

Posted by Robert Harper <ro...@iat-cti.com>.
In my servlet, I load a properties file that is in my [context_path]/classes
directory with the following line of code
m_resource = ResourceBundle.getBundle( "ctimpact", Locale.getDefault() );
This works fine for me. You could try removing the ".properties" part of the
file name. The API may be adding it by default. Also maybe move your
properties file to the classes directory.
I hope that helps.

Dear Mr. Harper,
Thank you for the response!
I set the path inside the ActionError constructor as follows:
public ActionError() {
m_resource = ResourceBundle.getBundle("/error.properties");
}
I thought the "/" meant the root directory inside
CATALINA_HOME/WEB-INF/classes/.
Since, my error.properties file is going inside the
CATALINA_HOME/WEB-INF/classes/org/coffeebreak/wrapper/ directory via
my Ant build script, I rewrote the code inside the constructor as:
public ActionError() {
// I removed the slash
m_resource = ResourceBundle.getBundle("error.properties");
}
And then it gave me that Missing exception...
What am I possibly doing wrong?
Sincerely,
James Dekker

Examples of the use of the above (without the platform variants) can be
found within Tomcat itself. The various language-specific .properties
files are packaged in jars in common/i18n; these are accessed through
various StringManager classes such as:
apache-tomcat-5.5.20-src/container/catalina/src/share/org/apache/naming/
StringManager.java

ResourceBundle.getResource("errors") will get errors.properties
language and country is self-explanatory..
variant is either
WIN for Windows, MAC for Macintosh, and POSIX for POSIX
The order to locate the resources properties file on your classpath is ..
a.. baseName + "_" + language1 + "_" + country1 + "_" + variant1
b.. baseName + "_" + language1 + "_" + country1
c.. baseName + "_" + language1
d.. baseName + "_" + language2 + "_" + country2 + "_" + variant2

It looks like it is looking for it in the root of either the machine or
CATALINA_HOME. Resolve the path correctly and you'll probably find your
problem. You didn't provide the path so the loader assumes the root.

Chris!
You hit the nail on the head!
Removing the .properties extension made it work!
Thank you so much! You rock!

When you use ResourceBundle.getBundle, you don't put the ".properties"
extension on the file. You need to change this line of code to this:
m_resource = ResourceBundle.getBundle("error");
By the way, it looks like you are on your way towards building an
internationalized component to help manage error messages, probably
wrapped-up with a validation framework.
Unless it is very important to develop this component in-house, might I
suggest looking at the jakarta commons validator package
(http://jakarta.apache.org/commons/validator/)?
I have never used commons-validator alone... I have always used it in
conjunction with Apache Struts, with which it is very well integrated.
Just a thought.
