How to force ADF to speak your language (or any common language) in the logs
By Blueberry Coder on Dec 13, 2012
When I started working for Oracle, one of the first tasks I was given was to contribute some content to a great ADF course Frank and Chris are building. Among other things, they asked me to work on a module about Internationalization. While doing research work, I unearthed a little gem I had overlooked all those years.
JDeveloper, as you may know, speaks your language - as long as your language is English, that is. Oracle ADF, on the other hand, is a citizen of the world. It is available in more than 25 different languages. But while this is a wonderful feature for end users, it is rather cumbersome for developers. Why is that? Have you ever tried to search the OTN forums for a solution with a non-English error message as your query? I have, once. But how can you force ADF to use English for its logging operations?
By default, ADF will output its error messages in the selected locale for the operating system account the application server runs on. You can change this behavior is to pass initialization parameters to the JVM used by the application server. It is even possible to specify the language and country/region separately. In the example below, we choose English and the United States respectively.
In the case of WebLogic Server, it is possible to add such parameters in setDomainEnv.sh (or .cmd) to apply the settings to all the managed servers present on a node.
In the coming weeks, I will write a few posts about other internationalization issues. Is there anything you would like me to cover? Let me know in the comments.
