Alguem sabe a razão ? Estou fazendo um exemplo simples… só uma entidade mapeada e um repositório.

#2

poste seu código, quem sabe alguém identifica algo.

qual servidor você ta usando?

#3

Bom o servidor de aplicação que estou usando é GlassFish

Agora é o seguinte estou com esse erro:
Caused by: java.sql.SQLException: Error in allocating a connection. Cause: Connection could not be allocated because: java.net.ConnectException : Erro ao conectar no servidor ‘localhost’ porta ‘1527’. Recebida a mensagem: ‘Conexão recusada’.

Acredito que o problema pode ser a falta de um mas não sei o que configurar nessa tag.
