ClassNotFoundException: com.ibm.icu.util.ULocale

[gaspo100]

When I deploy my app to server I get this exception:
"java.lang.ClassNotFoundException: com.ibm.icu.util.ULocale"

It works fine in development mode where ULocale is available through gwt-dev.jar.
However, after deploying, ULocale is not available in GWT's server side module (get-server.jar).

This is by design. You need to add the ICU4j jar located at http://site.icu-project.org/ to your classpath. The reason you have the ICU classes inside the gwt-dev.jar is because GWT includes them for its Java to JavaScript compiler. This is regrettable since it often times falsely reports the files on your classpath. Add the ICU4J jar and let me know if it works. Thanks.

Thanks, yes it works now with ICU4J jar. Quite large jar though (7MB).
