Please any idea.. ????
Hard to guess. Some thoughts that came to my mind:
Oracle server has appropriate settings for UTF-8 content?
You're using the correct datatype for those columns?
You're using the latest JDBC database driver ojdbc6.jar?
Do you have any NLS-variables set in your environment where starting jboss?
Thanks for reply..
Column data type : NCLOB;
Driver ojdbc6.jar : Version: 18.104.22.168.0 and I replaced with the latest one. but same result.
In DB, NLS_LANGUAGE : AMERICAN
Language characters are saved correctly with websphere and jboss 4.2. After migrating to jboss EAP 6, Language character saved as invalid. So problem should be with jboss EAP 6 configuration.
There are 17 Languages in the project. all non English characters are saved as ¿¿¿¿¿¿¿¿.
