oracle - Difference between ojdbc jar file versions -


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

ora-01017: invalid username/password; logon denied

after downgraded ojdbc7-12.1.0.2.jar , error message disappeared without modification of login credentials.

there big difference how these behaves , error message strange.

@plaidshirt : post answers part of question, older versions of oracle doesn't maintain case sensitivity, trying connect oracle db client, right ?? if password in 9i : mypass123, 9i sees mypass123 whereas 11g take according case of characters. so, if there issue in case of password returned ora-01017 gets resolved in lower versions of it, if character case issue.

i have following architecture: +-----------------+ | collection | | | | | | | | | +-----------------+ | ^ | | create() | | | | v | getitem(b) +------------+ | | item | | | | | | +------+ | | +------------+ a class managing collection of items, creates items. , these items may need other items collection. the actual code in python, , collection passes parameter created item . see it, bad practice. improvement can see pass few functions of collection needed item , instead of whole instance. for example: class collection: getitem(self, id): ... createitem(self, id): item = item(id, self) # <-- pass self ... class item: __init__(self, id, col): ... col.getite...
