I am having this error in my j2ee web application.

This project works in my colleagues' PCs... I mean this project works for them but when I asked for their project folder and imported it on my eclipse, when i run it i meet this error. The jar files are already packaged with the project folder.

I also created a simple j2ee project using hibernate but I had the same error. I tried to ping the DB server and browse it using PL/SQL developer and I don't have any problem with it

Answer 1

Try following:

1. Check that NLS_LANG setting is correct. On windows it is in registry under \HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE.
2. Check that Oracle client software is correctly installed.
3. Check if there are multiple Oracle homes on that computer. In that case, find active one and check if it works.
4. Test with SQL*Plus if there is one installed. Sql Developer works because it has its own client installation.

Edit:
Regarding drivers, check this site: Oracle Instant Client. There you will find documentation on minimum drivers installation needed for JDBC access to Oracle. I don't know much about that because I use .Net.

Edit 2:
See this question: NLS_LANG setting for JDBC thin driver. There is same error as you have and problem was that default locale for NLS LANG was not defined. Quote:

The NLS_LANG settings are derived from the java.util.Locale . Therefore, you will need to make a call similar to this before connecting:

  Locale.setDefault(Locale.<your locale here>);

Answer 2

I figured out that that you could pass that two params to your Java app to resolve the issue:

-Duser.country=en -Duser.language=en

You could configure the values at environment variable level as well (depends from your OS).

Answer 3

I had the same problem. The solution was to add the country and the language to sqldeveloper.conf

Please open the file:

\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf

And add the following:

AddVMOption -Duser.language=en
AddVMOption -Duser.region=us

The above does the trick.

Answer 4

First execute query:

select userenv('LANGUAGE') from dual;`

This will give oracle regional and language. Change the regional and language in OS, both should match.

Answer 5

If you are compiling with intelljIDE I advise you add following options in VMoptions found in configurations model

AddVMOption -Duser.region=us. 

Answer 6

Oracle JDBC driver implicitly executes following statement after opening new connection:

ALTER SESSION SET NLS_LANGUAGE='language' NLS_TERRITORY='territory'

In our case we had problems with Oracle XE 11g and default language/territory mappings embedded into JDBC driver: 'ru' locale was mapped to 'CIS' territory which is supported only by Oracle EE, but Oracle XE had 'RUSSIA' territory only. Here is the way we fixed this:

-Doracle.jdbc.territoryMap="ru=RUSSIA;RU=RUSSIA"

There is option for NLS_LANGUAGE(we had no problems with defaults):

-Doracle.jdbc.languageMap="ru=RUSSIAN;RU=RUSSIAN"

Fixed: constant ru=RUSSIAN taken from class oracle.sql.converter.CharacterSetMetaData of java jdbc driver.
