#1

Pessoal,

       estou tentando fazer uma aplicação utilizando Struts onde um JSP(index.jsp) chama outro jsp. Já configurei o struts-config.xml para executar um action que chama o outro jsp. Mas quando eu rodo o programa aparece o seguinte erro:

[code]type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

Oi

Amigao, este erro deve estar no strus-config ou no web.xml… eu apostaria mais no web.xml…

Posta aí o conteudo deles pra analisarmos… :grin:

É…
sem o conteúdo dos arquivos struts-config e web.xml fica dificil de saber…

Se der posta tb a seu action…

o web.xml eu nao consegui postar pq tinha erro de html tag…
