Method Detail

locateConfig

public static final URL locateConfig(String path)

Parameters:: path - The path representing the config location.
Returns:: An appropriate URL or null.

findAsResource

public static final URL findAsResource(String path)

Try to locate a local URL representing the incoming path. This method only attempts to locate this URL as a java system resource.

Parameters:: path - The path representing the config location.
Returns:: An appropriate URL or null.

public static final InputStream getConfigStream(String path)
                                         throws HibernateException

Open an InputStream to the URL represented by the incoming path. First makes a call to locateConfig(java.lang.String) in order to find an appropriate URL. URL.openStream() is then called to obtain the stream.

Parameters:: path - The path representing the config location.
Returns:: An input stream to the requested config resource.
Throws:: HibernateException - Unable to open stream to that resource.

getConfigStreamReader

public static final Reader getConfigStreamReader(String path)
                                          throws HibernateException

Throws:: HibernateException - Unable to open reader to that resource.
