Adding a new language to a project

[Cedric.Vidrequin]

Hi there !

I created a new project with SpringRoo 1.2.
I used the reverse engineering to generate all the BO objects, the service layer and the UI pages.

Now I try to internationalize my application.

I added the 6 languages handled by default by SpringRoo without any trouble.

Now I have several questions :

1) why are there only 6 languages handled by default ? I saw several properties files for other languages on internet : maybe they could be added ?

2) I tried to add new languages but it is very hard (at least for me...). I didn't understand the story about creating an i18n project ... but I found two existing project around French and Russian. I tried to add them using those two Roo commands :

osgi start --url http://spring-roo-addon-mvc-i18n-russian.googlecode.com/svn/repo/net/dzmitryb/roo/addon/mvc/russian/net.dzmitryb.roo.addon.mvc.russian/0.1.0.BUILD/net.dzmitryb.roo.addon.mvc.russian-0.1.0.BUILD.jar
osgi start --url http://code.google.com/p/fr-test/source/browse/repo/org/springframework/roo/addon/i18n/french/org.springframework.roo.addon.i18n.french/0.1.0.RELEASE/org.springframework.roo.addon.i18n.french-0.1.0.RELEASE.jar

... but this didn't work :'(
The first one added the messages_ru.properties file, the russian flag icon and changed the footer.jspx file ! But when I cliqued on the flag, I had the english language ...
I created the messages_fr.properties file, added the expected icon and changed the footer.jspx file ... same result !
I tried a lot of changes, install, uninstall, and ... suddenly, I don't know why, but it worked !

3) now I try to add portuguese language ... I added the properties file, the icon and changed the footer.jspx file ... but it doesn't work :'(
My question main is : all the structure is set so that the application can switch from one language to another, just by specifying the 2 letters country code :

<util:language label="English" locale="en"/>
OR
<util:language label="Français" locale="fr"/>

So why isn't it possible to simply add a new property file and a new button to make it works ?

Thanks in advance for attention.

Roo has a convenient, built-in add-on discovery mechanism which does exactly what you need:

roo> addon search french
1 found, sorted by rank; T = trusted developer; R = Roo 1.2 compatible
ID T R DESCRIPTION -------------------------------------------------------------
01 Y - 0.1.0.BUILD France language support for Spring Roo Web MVC JSP
       Scaffolding
--------------------------------------------------------------------------------
[HINT] use 'addon info id --searchResultId ..' to see details about a search result
[HINT] use 'addon install id --searchResultId ..' to install a specific search result, or
[HINT] use 'addon install bundle --bundleSymbolicName TAB' to install a specific add-on version
~.web roo> addon install id 1

This is also documented in our reference guide. The i18n addon creation steps are outlined here and here.

HTH,

Hello Stefan,

thank you for taking time to have a look at my problem !

As I said in my previous message, I managed to make work the French and the Russian languages, using the add-on discovery mechanism and some web search.

The problem I have is : how adding a new language that is not supplied in the add-on list ?
I'm trying to add Portuguese language : I have the messages_pt.properties file and the flag icon, I tried to create the i18n stuffs like this (but it fails) :

roo> addon create i18n --topLevelPackage com.myCompany.myProject --locale pt --messageBundle SpringRooI18nAddons/pt/messages_pt.properties
Command 'addon create i18n --topLevelPackage com.vialtis.ferry --locale pt --messageBundle SpringRooI18nAddons/pt/messages_pt.properties' was found but is not currently available (type 'help' then ENTER to learn about this command)

Did I miss something ?

Cédric.

The addon create command will only work in empty directories. This is because it will create a complete new project for your addon so you can package it as a (OSGi-ready jar bundle, and potentially make it available to other Roo users). Once you have created your addon project and packaged it (mvn package) you can install the addon:

roo> osgi start --url file:///<path-to-jar>foo.jar

Hi I'm having problems too when "Adding a new language to a project"
I want to make locale for Bosnian language in Latin and Cyrillic (http://en.wikipedia.org/wiki/Bosnian_language) So i will have to commands
//Cyrillic
addon create i18n --topLevelPackage spring.roo.addon.mvc.i18n.bosnian.Cyrillic --locale bs_cy --messageBundle messages_bs-Cyrl-BA.properties --language Bosanski --flaggraphic bs.png --description "Localization for Bosnian Cyrillic"

//latin
addon create i18n --topLevelPackage spring.roo.addon.mvc.i18n.bosnian.Latin --locale bs_la --messageBundle messages_bs-Latn-BA.properties --language Bosanski --flaggraphic bs.png --description "Localization for Bosnian Latin"


And when I add them
osgi start --url file:///....\spring.roo.addon.mvc.i18n.bosnian.cyrillic-0.1.0.BUILD-SNAPSHOT.jar
osgi start --url file:///....\spring.roo.addon.mvc.i18n.bosnian.latin-0.1.0.BUILD-SNAPSHOT.jar

In project in roo I can see them

roo>web mvc language --code
bs_la bs_cy de en es it nl sv

but i'm getting exception
java.lang.IllegalStateException: Failed to convert 'bs_cy' to type I18n for option ',code'
when adding language

roo> web mvc language --code bs_cy
java.lang.IllegalStateException: Failed to convert 'bs_cy' to type I18n for option ',code'


One strange thing is if I issue
addon create i18n --topLevelPackage spring.roo.addon.mvc.i18n.bosnian.Cyrillic --locale bs_cy --messageBundle messages_bs-Cyrl-BA.properties --language Bosanski --flaggraphic bs.png --description "Localization for Bosnian Cyrillic"

I have to modify in BosanskiLanguage class bs -> bs_cy

@Component(immediate = true)
@Service
public class BosanskiLanguage extends AbstractLanguage {

public Locale getLocale() {
return new Locale("bs");//change to bs_cy
}

public String getLanguage() {
return "Bosanski";
}

public InputStream getFlagGraphic() {
return FileUtils.getInputStream(getClass(), "bs.png");
}

public InputStream getMessageBundle() {
return FileUtils.getInputStream(getClass(), "messages_bs-Cyrl-BA.properties");
}
}

I know this is old but thought it was worth adding in, just in case others are looking.

I was able to add a new language to my Spring Roo JSF project just by:
1. Adding the image and link in the footer.
2. Creating the associated messages_<xx>.properties file
3. Adding in the language support to the faces config: (faces-config.xml)
