Struts -> bean:message -> "Missing key"

Pessoal,

Fui convencido (tarde demais) a estudar o Struts.

Baixei um strutsSample.war completo e executei sobre struts 1.0 com sucesso.

Tentei criar o meu primeiro projeto sobre struts 1.1 e ocorreram alguns problemas.

Estou obtendo a seguinte exceção tentando executar o “Login” Struts.

javax.servlet.ServletException: Missing message for key "login.title"

Aparentemente o struts não tá conseguindo achar meu ApplicationResources.properties (este é o arquivo de properties que contem login.title). Inicialmente eu coloquei o <init-param>application no meu web.xml, não funcionou, tentei então colocar no meu struts-config.xml:

&lt;message-resources 
        factory="org.apache.struts.util.PropertyMessageResourcesFactory" 
        key="org.apache.struts.action.MESSAGE" 
        null="true" 
        parameter="com.oreilly.ApplicationResources" /&gt;

Meu arquivo ApplicationResources.properties está no arquivo war dentro da estrutura:

&lt;my-web-context&gt;/WEB-INF/classes/com/oreilly

Ele tem uma chave “login.title” configurada corretamente.

Por favor, não me recomendem ver o struts-example.war, pois eu já o fiz :evil: . Funcionou legal.

Thanks

provavelmente você esta utilizando windows e esta com algum problema de case no nome do arquivo, tent renomear ele para alguma outra coisa e renomear de volta :slight_smile:

Valeu galera, tá funcionando :smiley:

Eu não entendi bem o que aconteceu, então refiz o módulo de “Login” do exemplo Struts a partir do zero e agora tudo funciona.

Devo ter tropeçado na versão anterior. :roll:

Obrigado pela ajuda.
