Hi martin,
Yes, Now that I look at Digester's faq, seems like this can be pretty
useful.Once the info in the files are available through java beans, i can
use them anywhere I want using the getter methods.
However, in my current scenario, looks like a simple key value pair, ie
having a .properties file would suit me better.
public static ResourceBundle confBundle = ResourceBundle.getBundle("package
name");
public static String getPropValue(String key){
String propValue = null;
propValue = confBundle.getString(key);
return propValue;
}
}
And i could call getPropValue to access the value stored in the .properties
file right?
However, tonight is going to be spent on learning digester:)
Thanks,
Vikas.

Yes, sure, you could just use an XML parser and do your own stuff. The
problem with this approach would be that changing your XML structure
would probably mean changing a lot of the processing.
This type of processing is handled by Digester which was originally made
to deal with Struts config files. It will (called at an appropriate time
in your app's lifecycle) convert your configuration information into
(one or several) Java beans which your application can access. Seems for
me exactly the thing you are looking for.
The other question is whether this machinery is worthwhile, if you are
just having a few key-value pairs which probably would be easier be put
into some plain text file (e. g a .properties file).
To give you an example how I do configuration in my Struts (1.x) based
apps:
I introduce a plugin where I pass the path of the config-file as a
parameter in struts-config.xml.
In the init-method of the plugin I use digester to transfer the
information from my config file into a configuration bean which is put
into application scope. From there it can be accessed when needed.
