Erro - VRaptor + JRDataSource - Resolvido

Assuntos Gerais
#1

Tenho uma classe que implementa um JRDataSource que utilizo para popular o relatório, um dao que gera um array de bytes e um controller para download do relatório.
Mas ao tentar executar o projeto o seguinte erro ocorre.

Você verificou se os jars do jasper estão na sua classpath , pois erro diz que não encontrou os jars necessários ? outra coisa que acontece são conflitos de versão …você não diz qual servidor esta utilizando,mas se for tomcat na pasta lib dependendo da versão já existe os jars do jasper … e isto pode ser algum conflito entre a sua versão e a do server …

#3

Estou usando ireport 4.5.0 e vraptor 3.1.2, meu tomcat é a ultima versão e não possui nenhum jar do ireport na pasta lib dele.O classpath está configurado corretamente e e os jars estão na pasta lib do web-inf.

O erro que ocorre agora mudou.

Boa tarde galera!

Dandanfonte, você comentou que o erro havia mudado. Você lembra o que você fez para corrigir o primeiro erro?

[code]GRAVE: Exception starting filter vraptor

[/code]

Obrigado.
