I tried to use ojdbc14.jar to connect to database. I got following error message:

ORA-01017: invalid username/password; logon denied

After that I downgraded it to ojdbc7-12.1.0.2.jar and this error message disappeared without modification of login credentials.

There is a big difference how these behaves and error message is strange.

@plaidshirt : that post answers some part of your question, that is the older versions of oracle doesn't maintain case sensitivity, as you were trying to connect to the oracle db client, right ?? like if your password in 9i was : myPass123, then 9i sees it as MYPASS123 whereas 11g would take it according to the case of the characters. So, if there was some issue in the case of your password which returned ORA-01017 gets resolved in lower versions of it, only if it was a character case issue.
