Web Service + Hibernate annotations

Front-end
#1

Olá pessoal,

estou com um problema no meu projeto.
Vou tentar resumir: criei um projeto usando Hibernate Annotations e testei todos os métodos. Ele funciona normal.
O problema é depois de gerar o Web Service e o cliente com o Axis2.
Quando eu vou testar o cliente do serviço no Web Service Explorer do Eclipse ele acusa este erro: [quote]HTTP Status 500 -

Alguém pode ajudar?

Valew!

Você deve colocar o JAR do hibernate no classpath para que o Axis consiga enxergar as classes. Provavelmente há uma forma de configurar o classpath para execução do Axis. Dê uma pesquisada.

Resolvido! :lol:

Coloquei o connectorJ do MySQL na pasta lib do Tomcat e deu certo. As demais eu deixei na aplicação mesmo.

Falow.

Estou revivendo a thread porque tenho um problema parecido com o seu.
Fiz uns testes com as minhas classes de persistencia e todas elas funcionam. Só da erro quando o web service é gerado, ou seja, quanto tento executar algum método do webservice.
O erro que dá é este aqui:
