ClassNotFound… pelo jeito você não colocou os jar’s do Struts corretamente na sua aplicação… verifique as configurações do Classpath, veja se os jar’s estão sendo referenciados…

donny 19 de ago. de 2010

Aew Marcelo! As libs foram a primeira coisa que verifiquei. Segue a imagem abaixo:

abelgomes 19 de ago. de 2010

esta parecendo que tem algum JAr faltando.
Mas no meu WEB.XML esta assim

action *.do e no seu esta ssim # # testeDeStruts # *.do #

nao sei se tem haver…mas eu diria que é lib.

donny 19 de ago. de 2010

É o que parece ser, mas eu adicionei todos os JAR do zip do Struts no meu projeto. Tbm fiz a alteração no WEB.XML e persiste o mesmo erro nos logs do tomcat.

marcelo.bellissimo 19 de ago. de 2010

Como você está “subindo” o seu projeto? Por dentro do Eclipse, ou você está fazendo o deploy da aplicação no seu Tomcat manualmente?

Se for pelo Eclipse, verifique nas propriedades dele (aba Servers, clica com o direito e em Properties) qual o “Location” que está lá… pra funcionar deve ser o “[workspace metadada]”…

donny 19 de ago. de 2010

Ok Marcelo, fiz o que vc mandou, mudei o location para [Workspace metadata] pq estou executando por dentro do eclipse.

Agora o erro é outro:

Tá faltando a tag DOCTYPE no seu XML... é pra ficar assim:

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot; ?&gt;

&lt;!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
          "http://jakarta.apache.org/struts/dtds/struts-config_1_3.dtd"&gt;
