Problemas com struts

Front-end
#1

Pessoal,

Estou iniciando com o desenvolvimento através de struts, e me deparei com um erro cuja solução não estou encontrando.

o Erro é o seguinte:

HTTP status 500 - No action instance for path /buscarCadastroFuncionario could be created

meu struts-config.xml

    <!-- ========================= Tiles plugin ===============================-->
    <!--
    This plugin initialize Tiles definition factory. This later can takes some
    parameters explained here after. The plugin first read parameters from
    web.xml, thenoverload them with parameters defined here. All parameters
    are optional.
    The plugin should be declared in each struts-config file.
    - definitions-config: (optional)
    Specify configuration file names. There can be several comma
    separated file names (default: ?? )
    - moduleAware: (optional - struts1.1)
    Specify if the Tiles definition factory is module aware. If true
    (default), there will be one factory for each Struts module.
    If false, there will be one common factory for all module. In this
    later case, it is still needed to declare one plugin per module.
    The factory will be initialized with parameters found in the first
    initialized plugin (generally the one associated with the default
    module).
    true : One factory per module. (default)
    false : one single shared factory for all modules
    - definitions-parser-validate: (optional)
    Specify if xml parser should validate the Tiles configuration file.
    true : validate. DTD should be specified in file header (default)
    false : no validation

    Paths found in Tiles definitions are relative to the main context.

Oi, Eduardo.

Seria melhor se você incluisse o trace do erro. Verifique o arquivo de log.

Mas apenas o trace do erro, por favor. :slight_smile:

Abraço.

O netbeans nao mostra o trace d erros com relacao a esse problema.
A unica coisa que aparece é essa msg HTTP Status 500… no browser.

Obrigado!

Cara, não olhei todos os códigos, mas pelo que pude perceber parece que ele não está encontrado path /buscarCadastroFuncionario, acho que é isso.

Muito estranho isso. Já olhou se a estrutura de seus arquivos está certa e se seu web.xml está configurado certo tb?

Descobri o problema!!!

Na verdade o .class estava com o “a” do Action minúsculo. Eu alterei e compilei a classe umas mil vezes, entretanto ele nao substituia o .class com o nome errado pelo nome certo.

Enfim, o problema está solucionado! Mto Obrigado a todos que ajudaram!!!
