Is it possible to transfer an application bought under one Apple ID to another Apple ID? How to see apps from different accounts

Is it possible to see apps you got from a different account? I signed off one of my accounts where I had a paid app but I deleted it! The thing is, I forgot the password, so I have another account. The problem is that now I can't get back that app without paying again... U-U I don't mind so much about paying once more, but still, it's a bit frustrating! Help?!?

For those who find this unclear, I'll try my best to make it as clear as possible.
I have two accounts, one French account and the other Canadian
On my french account, I brought minecraft. 
I signed off the french account, but made the unfortunate mistake of forgetting the password and switched to my Canadian account.
Since I was trying to make space for another app, thinking I would be able to get minecraft back, I deleted the app.
In the end, my iPad kept saying I had no space left, therefore not able to get minecraft back. I am still on my Canadian account, wishing to see the apps on my french account to try to get minecraft back for free.
No. All applications downloaded by one Apple ID (free or not) and non-transferrable. iTunes support will tell you the same. There is nothing that can be done outside of retrieving/ resetting your password to the original Apple ID associated with the purchase. Then you can download the application again. Contact iTunes support to reset your Apple ID password.
