Method Detail

locateConfig

public static final URL locateConfig(String path)

Try to locate a local URL representing the incoming path. The first attempt assumes that the incoming path is an actual URL string (file://, etc). If this does not work, then the next attempts try to locate this UURL as a java system resource.

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 UURL as a java system resource.

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

getConfigStream

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

Open an Reader 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 a stream, which is then wrapped in a Reader.

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

getConfigProperties

public static final Properties getConfigProperties(String path)
                                            throws HibernateException
