Here's the scenario:
I have JDeveloper 11g and a project loaded. I go to Database Navigator and right click on IDE Connections and select New Connection.
I leave thje conneciton name to default; enter username and password that I know are fine because I can connect through Toad.
Driver is thin; I enter host name I get from tnsnames.ora file, which I can ping; port 2115, which they tell me is the right one; and a service name from the tnsnames file.
The result of test connection is:Test failed: oracle.i18n.text.converter.CharacterConverterOGS.getInstance(I)Loracle/sql/converter/CharacterConverters;
Does anyone have any idea what is wrong?
