Srs:
Tenho uma aplicacao que usa struts e hibernate, ela esta funcional e configurada perfeitamente.
No entando estou com o problema para tratamento dos erros lancados pelo hibernate, como no caso de uma chave duplicada.
Para evitar ter que fazer um select antes de cada insert para linhas iguais, eu criei uma chave primaria que deveria me permitir que eu inserisse varias linhas sem problemas.
O que acontece eh que a cada exceccao do hibernate a aplicacao para com erro e eu queria que continuasse traalhando. O que nao consigo eh capturar o erro por bloco try catch, que mesmo capturada para a aplicacao.
Segue algumas configs…
