Ola a todos,
Estou tendo problemas com castor, utilizo o framework para acesso de banco
de dados, ele faz a tradu��o de objetos para o banco relacional que, no
caso, estou utilizando o Oracle 8i.
Quando executo um update de um objeto, funciona perfeitamente, mas quando
vou fazer um outro update no mesmo objeto ele gera uma exce��o como vista
abaixo.
Depois disso, n�o consigo realizar nenhuma opera��o no banco, ficando em
deadlock. Ou seja, fico esperando, esperando....

Algu�m que ja trabalhou com o castor, tem alguma ideia de como posso
resolver?
