[Keph]

Bonjour à tous.

Je suis nouveau avec Struts (et le web dev avec Java). Avec mes collègues de promo, nous avons écrit une petite application qui fonctionne plutôt bien. Par contre, après une dizaine de requêtes struts (*.do), aucune page n'est rendue. En regardant le status de tomcat, on se rend compte que la requête est en statut "Service" et ce depuis un temps incroyablement long (aussi longtemps que l'on attende)

Cette image vous expliquera la situation bien mieux que mon texte : (voir la 3eme ligne : "POST ProjetSI/Connection.do HTTP/1.1") Elle provient du manager de tomcat 6.


Diminuer l'option "maxWaitTimeout" ou "connectionTimeout" de la configuration de Tomcat n'y change rien.

Voici le server.xml de Tomcat :

    <!-- ========================= 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.

Et bien entendu, rien n'apparait dans les logs de Tomcat.

Je suis désolé si ma description du problème n'est pas très précise, j'ai du mal à l'exprimer.

J'espère que mon erreur vous sautera aux yeux.

Bonne journée et merci d'avance,
