RE: [Configuration] Hierarchical Configuration Problem: Newbie

["Tong, Andrew" <AT...@CreativeSolutions.com>]

Although I've never used commons-configurations, the NoSuchMethodException
leads me to believe that you need to have JDK 1.4 or higher.  The docs say
that the StringBuffer.indexOf(String) method was introduced in that version.

http://java.sun.com/j2se/1.4.1/docs/api/java/lang/StringBuffer.html#indexOf(
java.lang.String)

Subject: Hierarchical Configuration Problem: Newbie


Hi Everybody,

I am trying to learn the commons-configuration from the examples given on
the website http://jakarta.apache.org/commons/configuration/examples.html

Things were working as expected until I started to use the Hierarchical
Properties. I'm listing my source code, the exceptions that I'm getting and
the properties file that I'm using. I would appreciate any thoughts.

Thanks

Vikas

---------------Source Code----------------------------------
public class FirstConfig {

	public static void main(String[] args) throws Exception{
		
		
		ConfigurationFactory configFactory = new
ConfigurationFactory();
		URL configFile = new File("config\\config.xml").toURL();
		System.out.println("URL== "+ configFile);
		configFactory.setConfigurationURL(configFile);		
		Configuration config = configFactory.getConfiguration();

		String backgroundColor =
config.getString("color.background");
		String textColor = config.getString("color.text");
		String rows = config.getString("rowsPerPage");
System.out.println("Here is the back ground color property: "+
backgroundColor);
System.out.println("Here is the text color property: "+ textColor);	
System.out.println("Here is the rows per page property: "+ rows);

//Everything is working perfectly fine till here

Object tablename = config.getProperty("tables.table(0).name");
System.out.println("Here is tablename.toString() : "+tablename.toString());
		
		
	}
}

--------------Exception Stack Trace----------------------------------------
