Apache MyFaces Trinidad is using its maven-xrts-plugin to generate Message Bundle classes out of a XML file for internationalization (i18n). (X)RTS is a proprietary XML format to represent key/value pairs with namespaces. I'll show how to add the plugin to your pom.xml and how to use the format to generate Message Bundle classes.See
rts.dtd in trinidad-api for details about the format, although there is not much more than the example below shows.First, create a
src/main/xrts/MyMessages.xrts:<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE resources SYSTEM "rts.dtd">
<resources xmlns="http://mhaller.de/rts" package="de.mhaller.resource">
<resource key="foo">bar</resource>
</resources>
To use the maven-xrts-plugin, you need to add it to the
generate-sources lifecycle goal of your project's Maven pom.xml:<plugin>
<groupId>org.apache.myfaces.trinidadbuild</groupId>
<artifactId>maven-xrts-plugin</artifactId>
<version>1.0.2-SNAPSHOT</version>
<executions>
<execution>
<goals>
<goal>generate-sources</goal>
<goal>generate-test-sources</goal>
</goals>
</execution>
</executions>
</plugin>
As the generated source uses the Java 5
@Override annotation, you should also set the Java Source Level version to 1.5, ifnot already done in your project.
Now, run Maven:
mvn packageThe following Java Source Code is automatically generated and packaged for each
*.xrts resource found within your projects src/main/xrts folder:// Do not edit this file!
// This file has been automatically generated.
// Edit MyMessages.xrts and run the XRTSMakeBundle tool instead.
//
package de.mhaller.resource;
import java.util.{FNAMEL}+java.sun.com&btnI=I%27m%20Feeling%20Lucky">ListResourceBundle;
public class MyMessages extends {FNAMEL}+java.sun.com&btnI=I%27m%20Feeling%20Lucky">ListResourceBundle {
@Override
public {FNAMEL}+java.sun.com&btnI=I%27m%20Feeling%20Lucky">Object[][] getContents() {
return new {FNAMEL}+java.sun.com&btnI=I%27m%20Feeling%20Lucky">Object[][] {
{"foo", "bar"},
};
}
}
// This file has been automatically generated.
// Edit MyMessages.xrts and run the XRTSMakeBundle tool instead.
//
package de.mhaller.resource;
import java.util.{FNAMEL}+java.sun.com&btnI=I%27m%20Feeling%20Lucky">ListResourceBundle;
public class MyMessages extends {FNAMEL}+java.sun.com&btnI=I%27m%20Feeling%20Lucky">ListResourceBundle {
@Override
public {FNAMEL}+java.sun.com&btnI=I%27m%20Feeling%20Lucky">Object[][] getContents() {
return new {FNAMEL}+java.sun.com&btnI=I%27m%20Feeling%20Lucky">Object[][] {
{"foo", "bar"},
};
}
}
