Method Detail

createConfiguration

protected UriResolver.Configuration createConfiguration(Extractor extractor,
                                                        String entity)

resolveUri

public UriResolver.Configuration resolveUri(String uri)

resolve the given uri

resolve

protected UriResolver.Configuration resolve(String scheme,
                                            String path)

Look in all META-INF directories in the classpath for a file of name "dynaForm-scheme.xml", where scheme is a parameter to this method.

From that file, load a Properties object and get the value of key "Extractor", which is expected to be the name of a class that implements the Extractor interface.

Use the Extractor instance to return a simple (extractor, classname) pairing. TODO: use the normal java Service configuration approach instead.

findConfig

protected InputStream findConfig(String config)

load the configuration

getResourceAsStream

protected InputStream getResourceAsStream(String resource)

getRequiredProperty

protected String getRequiredProperty(String config,
                                     Properties props,
                                     String key)
