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:

type Exception report

message 

description The server encountered an internal error &#40;&#41; that prevented it from fulfilling this request.

exception 

org.apache.jasper.JasperException
	org.apache.jasper.servlet.JspServletWrapper.service&#40;JspServletWrapper.java&#58;372&#41;

Alguem pode me ajudar? o que pode ser esse erro?

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…

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