O arquivo GrvModulo.class deveria estar em WEB-INF/classes/com/sistema/modulo/gprojetos. Coloque ele la, reinicie o servidor e tcha-rans!

leonardobaiao 22 de out. de 2003

O arquivo GrvModulo.class esta no diretorio: WEB-INF/classes/com/sistema/modulo/gprojetos

dreamspeaker 22 de out. de 2003

Cara, então parece não ter nada errado.

Já tentou fazer…

… sem o “/” ?

cv1 22 de out. de 2003

Acho que tambem nao vai funcionar, Andre… provavelmente o problema eh mais embaixo…

Leonardo, o que os logs de erro do seu servidor dizem?

Paulo_Silveira 22 de out. de 2003

coloque o log relativo a sua webapplication
abre o catalina.out ou o localhost_log, dpeendnedo do tomcat que voce ta rodandno, e procura pelo log.

se for tomcat 4.0.x ele sai no console tambem.

leonardobaiao 22 de out. de 2003

A versão do Tomcat que estou utilizando é 5.0.9

Não tem nada referente esse erro nos arquivos de log.

Mensagem de erro no tela:
HTTP Status 404 - /jsistema/modulo/gprojetos/GrvModulo
The requested resource (/jsistema/modulo/gprojetos/GrvModulo) is not available.

Agora, quando eu inicio a aplicação ele gera esse erro no log.

Leonardo, o Tomcat 5 ainda esta em desenvolvimento, e pode ter bugs (como esse que vc acabou de achar :D). Pegue o Tomcat 4.1.x

Ok. Já vou providenciar a troca…

Paulo_Silveira 22 de out. de 2003

Aproveita e coloca os códigos do seu servlet e da página JSP para onde o servlet redireciona o fluxo da sua aplicação.

P.s.: como está a estrutura de diretórios onde o seu servlet foi colocado?

leonardobaiao 22 de out. de 2003

agradeço a ajuda de todos…

descobri aonde estava o problema… era no caminho do jsp no web.xml
