loadInstance

public static WorkCatalog loadInstance(PegasusProperties props)
                                throws WorkFactoryException

Connects the interface with the work catalog implementation. The choice of backend is configured through properties. This class is useful for non-singleton instances that may require changing properties.

Parameters:

props - is an instance of properties to use.

Throws:

ClassNotFoundException - if the schema for the database cannot be loaded. You might want to check your CLASSPATH, too.

NoSuchMethodException - if the schema's constructor interface does not comply with the database driver API.

InstantiationException - if the schema class is an abstract class instead of a concrete implementation.

IllegalAccessException - if the constructor for the schema class it not publicly accessible to this package.

InvocationTargetException - if the constructor of the schema throws an exception while being dynamically loaded.
