cocoon version: 2.0.2
servlet engine: tomcat 4.0.3
OS: windows 2000
JDK: 1.4.0
I am trying to add internationalisation to my site by using i18n. After a day fruitlessly trying to figure out where I am going wrong I added some debug printlns to the I18nTransformer source. My setup is as follows:
******************** sitemap: ***************
<map:transformer name="i18n" src=""org.apache.cocoon.transformation.I18nTransformer">
<catalogue-name>messages</catalogue-name>
<catalogue-location>translations</catalogue-location>
<cache-at-startup>true</cache-at-startup> <----- I added this to make debugging easier as the cache is a simple hash table
</map:transformer>
.
.
<map:match pattern="login">
<map:act type="locale"/>
<map:aggregate element="page" label="raw-xml">
<map:part src=""cocoon:/login.banner"" />
<map:part src=""cocoon:/login.xml"" />
</map:aggregate>
<map:transform type="i18n" label="trans-xml"/>
<map:transform src=""stylesheets/page2html.xsl"" />
<map:serialize />
</map:match>
******************* dictionary: **************
in $TOMCAT_HOME/webapps/myapp/translations
/messages.xml
/messages_en.xml
/...etc,etc
******************* messages contain: *****
<catalogue xml:lang="en">
<message key="login.redirect">Go to Secure Login</message>
<message key="login.welcome">Welcome</message>
... etc, etc
</catalogue>
****************** xsp: **********************
<title name="login.welcome" i18n:attr="name"/>
<input type="submit"><i18n:text>login.redirect</i18n:text></input>
Now. At the browser I am getting the 'login.welcome' and 'login.redirect' keys untranslated. My debug statements showed that the string passed into XMLResourceBundle.getString(String key) was "/catalogue/message[@key='login.welcome']", but the XMLResourceBundle cache contained the key "/message[@key='login.welcome']". Clearly a mismatch. So I looked at the code:
I18nTransformer.getString() method prepends the key to be passed to the XMLResourceBundle.getString() with I18N_CATALOGUE_PREFIX. I18N_CATALOGUE_PREFIX is the string constant "/catalogue/message". XMLResourceBundle.cacheAll(Node parent, String pathToParent) is initially entered with a pathToParent of "" from init(). The pathToChild StringBuffer takes this as the initial buffer value in the line:
StringBuffer pathToChild = new StringBuffer(pathToParent).append(child.getNodeName());
If I change the initial call to cacheAll with a pathToParent of "/", and change the above line to
StringBuffer pathToChild = new StringBuffer(pathToParent).append(parent.getNodeName()).append('/').append(child.getNodeName());
I reproduce the expected key in the cache hashtable, and everything works.
Is this a bug in cocoon 2.0.2 or is there an alternative solution to this without changing cocoon source code?
Thanks,
Brian Buckley.
