Borut,
If you want to configure environments differently, I suggest looking
into resource filtering via maven.
see my thread titled 'configuration strategy' for more info.

Hi,
I would still like an advice on the approach on how to initialize custom
symbol provider with tapestry provided symbol. The code below ends in
IllegalStateException
Construction of service 'SymbolSource' has failed due to recursion: the
service depends on itself in some way.
The code from AppModule:
public RESTSymbolProvider buildRESTSymbolProvider(Logger logger,
@Inject @Symbol(SymbolConstants.EXECUTION_MODE) String executionMode) {
return new RESTSymbolProvider(logger, executionMode);
}
public void contributeSymbolSource(OrderedConfiguration<SymbolProvider>
providers, Logger logger,
@InjectService("RESTSymbolProvider") SymbolProvider
restSymbolProvider) {
providers.add("myAppConfiguration", restSymbolProvider);
}
Thanks for any input,

Hello,
I am in a process of writting my own SymbolProvider (the configuration for
my app will come from REST service) and I am facing a dilemma. The
contribution looks like:
public void
contributeSymbolSource(OrderedConfiguration<SymbolProvider> providers,
Logger logger) {
providers.add("myAppConfiguration", new RESTSymbolProvider(logger,
"development"), "after:SystemProperties", "before:ApplicationDefaults");
}
You can see I hardcoded the string "development". I want to replace this
string with another symbol
@Symbol(SymbolConstants.EXECUTION_MODE) String executionMode
As I need this symbol in another method (sendEmailMessage) in the
AppModule I naively tried like this and failed:
public class AppModule {
private String *executionMode*;
public AppModule(@Symbol(SymbolConstants.EXECUTION_MODE) String
executionMode) {
this.executionMode = executionMode;
}
@Startup
public void sendEmailMessage(Logger logger) {
if ("development".equals(*executionMode*)) {
logger.info(MarkerFactory.getMarker("EDITORS"), "DEVELOPMENT
Starting najdi-web");
} else {
logger.info(MarkerFactory.getMarker("EDITORS"), "PRODUCTION
Starting najdi-web");
}
}
public void
contributeSymbolSource(OrderedConfiguration<SymbolProvider> providers,
Logger logger) {
providers.add("myAppConfiguration", new RESTSymbolProvider(logger,
*executionMode*), "after:SystemProperties", "before:ApplicationDefaults");
}
...
}
Fails with:

Am I facing multiple problems here?
