Specify SymbolProvider at runtime
Hi, I was wondering what is the best way of doing this:
From the JVM arguments, I want our developers to specify a location to a
properties file, which will be treated as a symbol source. I tried a naive
approach and got a recursion error on SymbolSource.
In one of my modules I have this:
@Contribute(SymbolSource.class)
public void contributePropertiesFileAsSymbols(
OrderedConfigurationSymbolProvider configuration) {
configuration.add(DatabaseConfiguration,
new ClasspathResourceSymbolProvider(dbPropertiesFileLocation),
after:SystemProperties, before:ApplicationDefaults);
}
and essentially I'd like the variable dbPropertiesFileLocation to be
something provided on the command line, i.e.
-Dmyapp.db-properties-file-location=C:\mydatabase.properties
Inside the properties file are several settings that I want to use as
inject-able Symbols. That part already working when I provide the location
in the contribute method, but now I want to tell Tapestry where that file
lives on startup.

Why don't you use System.getProperty() to get the value passed as a
command-line parameter?

Re: Specify SymbolProvider at runtime
Thanks Thiago, you are right. I was so caught up in trying to use the
Symbols that I forgot the obvious. :-)
