Hi. I just tried JDeveloper 10g (10.1.2) and I cann't connect to my database (JDeveloper 9i works fine). I've got ORA-12705 error (wrong NLS). I need Russian language support so I use koi8 charset. On my Linux system I tried various combinations of NLS_LANG like AMERICAN_AMERICA.CL8KOI8R but it had no influence on connection result. Only after changing system variable LANG from "ru_RU.koi8r" to "C" I've connected to database. But so I lost ability to edit russian text. Can anyone help me? Thanks.
