<dev> <url>http://example.com</url> </dev> </config>

Notice I'm configuring both local and dev environment is same file, cool!

And load it:

try { config = new     XMLConfiguration(SolrConfig.class.getResource("data.xml")); EnvironmentConfiguration config = new EnvironmentConfiguration(); env = config.getString("env"); // Environment if (env==null) { env = "local"; // by default it's local } logger.info("'"+env+"' Environment detected!"); } catch (Exception e) { logger.severe("Configuration error: "+e.getMessage()); }

Note: you can access environment variables too and differentiate between various environments.

add a environment aware method to your code:

public String getProperty(String key) {     key = env.trim()+"."+key.trim();    return this.config.getString(key); }

And that's how you access the property within your xml configuration: config.getProperty("url")
