No there is no such sample. But it is very easy to do.
Have a look at o.a.ojb.broker.util.configuration.impl
OjbConfiguration extend ConfigurationAbstractImpl that provides all
neccessary infrastructure for loading the properties file and to
retrieve config settings.
you have to provide your own Configuration class that extends
ConfigurationAbstractImpl. to load a special file you have to overwrite
load():
/**
* loads the configuration
*/
protected void load()
{
setFilename("myProps.properties");
super.load();
...
}
You also will have to implement your own Configurator. OjbConfigurator
code will show you how easy this is to do.
cheers,
Thomas
