Re: ... a transaction, reset caller principal

[Stefan Groschupf <sg...@media-style.com>]

Hi Kazuhito,

thank you that helped very much!
I notice a strange side effect.
After closing the transaction my caller principal is reseted.

So I use the authentication mechanism described in cactus doc and it 
working fine in my test method until i start / commit the transaction.
Someone have any idea what kind of relation transactions and the caller 
principal have in weblogic?

Thanks
Stefan
