My Python script updates Oracle passwords regularly using the command
    alter user my_user identified by "new_password" replace "old_password"
Now I need to update these passwords in the SQL Developer connection definitions. I have looked all over my Windows 7 machine but nowhere can I find Connections.xml, nor IDEConnections.xml. And if so, the passwords would be encrypted.
Can anybody automate password updates for SQL Developer?
Robertus post pointed me in the right direction as to the location of the relevant configuration files; however, the password encryption is not solved yet. Re-opening a new question.
