Ola á pessoal
Estou tentanto usar o Hibernate em uma pequena aplicação rodando no TOMCAT.
Ela rodou legal em uma aplicação desktop, mas quando tento usar o tomcat fornecendo um DataSource…aí que as coisas complicam.
Eu estou recebendo uma mensagem que diz que nao consegui fazer o BIND do SessionFactory com o JNDI.
Alguem tem alguma observação, dica ou sugestao???
Obrigado.
