I need to access <context-param> values defined in web.xml from my Seam application. In this case, I need to use a couple of items when the application is initialized. The easy part was creating the class at application startup:
@Name("applicationPrefs")
@Scope(ScopeType.APPLICATION)
@Startup
public class ApplicationPrefs {
}
Finding the properties I cared about was harder. I knew they would be buried inside the ApplicationContext so I included the code:
Context ctx = Contexts.getApplicationContext();
String[] ctxNames = ctx.getNames();
and displayed the names and their associated values. I figured out that I could get the properties by adding:
HashMap<Object, Object> seamProps =
(HashMap<Object, Object>) ctx.get("org.jboss.seam.properties");
The keys are all Strings and the values are all instances of org.jboss.seam.util.Conversions$FlatPropertyValue so the value canreally be pretty much anything. all we care about are a couple of String values, so we can convert using only the toString method.
I'm fetching my values using:
String configFilePath = seamProps.get("configFile").toString();
It's great how easily I can get the info I want, but I'd prefer to use a standard way to get the properties instead of digging around for something that may not be standard that I figured out by reverse-engineering.
Is there a cleaner way to get this info? Is it documented anywhere? How would I convert things that aren't Strings?
