ORA-01882: timezone region not found
I'm accessing an Oracle Database from a java application, when I run my application I get the following error:
java.sql.SQLException: ORA-00604: error occurred at recursive SQL level 1 ORA-01882: timezone region not found

You may also try to check the version of the Oracle jdbc driver and Oracle database. Just today I had this issue when using ojdbc6.jar (version 11.2.0.3.0) to connect to an Oracle 9.2.0.4.0 server. Replacing it with ojdbc6.jar version 11.1.0.7.0 solved the issue.
I also managed to make ojdbc6.jar version 11.2.0.3.0 connect without error, by adding oracle.jdbc.timezoneAsRegion=false in file oracle/jdbc/defaultConnectionProperties.properties (inside the jar). Found this solution here (broken link)
Then, one can add -Doracle.jdbc.timezoneAsRegion=false to the command line, or AddVMOption -Doracle.jdbc.timezoneAsRegion=false in config files that use this notation.
You can also do this programmatically, e.g. with System.setProperty.
In some cases you can add the environment variable on a per-connection basis if that's allowed (SQL Developer allows this in the "Advanced" connection properties; I verified it to work when connecting to a database that doesn't have the problem and using a database link to a database which has).
