Re: Access the ApplicationGlobals inside the AppModule::bind() method
Thank you for this very quick and clear answer! Does it mean that I will be able to inject the PropertiesFileSymbolProvider object inside the AppModule::bind(ServiceBinder binder, @InjectService(PropertiesFileSymbolProvider) SymbolProvider propertiesFileSymbolProvider) method this way? Or should I declare a @Inject @Symbol(value=MyParam) private String myParam; (should be static) inside my AppModule (after having declared the properties symbol provider via the public PropertiesFileSymbolProvider buildPropertiesFileSymbolProvider(Logger logger) and public static void contributeSymbolSource(OrderedConfigurationSymbolProvider configuration, ... methods)? Because I need to access the property before the service is created, since it's implementation should depend on some property. Thank you.

Re: Access the ApplicationGlobals inside the AppModule::bind() method
Some of us (including me) tried to do the same thing but failed. See here http://markmail.org/message/hdcboxjrxkrgruyy for the discussion. It seems to come down to the order in which services are instantiated. By the time your service is being instantiated, the ServletContext has not yet been set in the ApplicationGlobals service and thus is null. At the moment, there doesn't seem to be a workaround if you want to configure your services whith init-params. You could, however, use a properties file. How to do that is explained here: http://wiki.apache.org/tapestry/Tapestry5HowToReadSymbolsFromPropertiesFile HTH, Uli Am Di, 7.10.2008, 10:42, schrieb Edouard sur edouardmercier.fr: Hello again. I would like the service implementation binding (inside the AppModule::bind(ServiceBinder binder)) to depend on the web.xml configuration file. This is the reason why I would like to access the ApplicationGlobal instance inside the method (in order to call as globals.getServletContext().getInitParameter(MyParam)), so as to provide the right implementation depending on some context-param value. Is it feasible? Is there a work-around, or another way to achieve that, please? Thank you so much for your help.

Re: Access the ApplicationGlobals inside the AppModule::bind() method
After you defined the PropertiesFileSymbolProvider, you have to contribute
it to the SymbolSource service (see the HOWTO). Afterwards you can just
@Inject @Symbol(your-symbol-name-here) final String something into your
service builder method, e.g.
public YourService buildYourService(@Inject @Symbol(mysymbol) final
String mysymbol)
{
// do something using mysymbol
}
The symbol's value will be searched in different places (see the HOWTO),
including the PropertiesFileSymbolProvider if contributed...

Re: Access the ApplicationGlobals inside the AppModule::bind() method
Just bind(@Inject @Symbol(some.identifier) String someSymbol) I think. This initiates the construction of symbolsource, which in turn calls the contribute in your appmodule which initiates the construction of the PropertiesFileSymbolProvider which reads the file. And btw, I would recommend http://www.nabble.com/Tapestry-f302.html to read the post lists. You see both developer and user forums from that link, but can filter either one by choosing the appropriate one from the top of the page.
