    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.

merci d'avance

La plupart du temps, on obtient ce message lorsqu'il y a une erreur au parsing du fichier struts-config.xml.

Dans le struts-config.xml, il y a une erreur dans le mapping suivant :

Code xml :

Sélectionner tout - Visualiser dans une fenêtre à part

<action input="/ajout_client.jsp" name="NewStrutsActionForm" path="/ajou_clt"
        scope="session" type="com.myapp.struts.NewStrutsAction"/>
        <forward name="success" path="/ajout_client.jsp"/>
</action>

Tu as fermé la balise action alors qu'elle contient une balise forward.
Il faut donc plutôt coder :

Code xml :

Sélectionner tout - Visualiser dans une fenêtre à part

<action input="/ajout_client.jsp" name="NewStrutsActionForm" path="/ajou_clt"
        scope="session" type="com.myapp.struts.NewStrutsAction">
        <forward name="success" path="/ajout_client.jsp"/>
</action>

Sinon, dans le mapping suivant :

Code xml :

Sélectionner tout - Visualiser dans une fenêtre à part

<action input="/" name="NewStrutsActionForm" path="/a" scope="session" type="com.myapp.struts.NewStrutsAction"/>

Dans l'attribut input, il faut spécifier la ressource (jsp ou autre) qui sera appelée en cas d'erreur de validation.

Et enfin, dans l'ActionForm NewStrutsActionForm, il faut ajouter un constructeur sans argument.
