you never wrote whether your simple test apps worked or not ;-).
I would assume that there is a configuration "error". Configuring an Oracle is a bit of science...
I tried to insert throrgh plssqldeveloper .
Also i tried through java. reading the file content line by line and used jdbc statement to insert table .
after that also getting ?????
Any idea ?? how i can insert correctly ???
please tell me: did you check that your simple test apps worked? Did you try to read the data from your database?
If it works: is the test client running on the same machine as JBoss? Compare the JDBC parameters of test client and JBoss data source.
If the test app does not work: then this is a matter of oracle related forums ;-)
