10.25. Configuring the Enterprise Service Bus

All components within the core of the product receive their configuration parameters as XML. How these parameters are provided to the system is hidden by the org.jboss.soa.esb.parameters.ParamRepositoryFactory:
public abstract class ParamRepositoryFactory
{
	public static ParamRepository getInstance();
}
This instruction returns implementations of the org.jboss.soa.esb.parameters.ParamRepository interface which allows for different implementations:
public interface ParamRepository
{
	public void add(String name, String value) throws
	ParamRepositoryException;
	public String get(String name) throws ParamRepositoryException;
	public void remove(String name) throws ParamRepositoryException;
}
Within the JBoss Enterprise SOA Platform, there is only a single implementation (the org.jboss.soa.esb.parameters.ParamFileRepository) which expects to be able to load the parameters from a file. The implementation to use this may be over-ridden using the org.jboss.soa.esb.paramsRepository.class property.

Note

Red Hat recommends that you construct your ESB configuration file using JBoss Developer Studio or an XML editor of your choice. The JBossESB configuration information is supported by an annotated XSD, which should be of help if you are using a more basic editor.
