Method Details

clearDSCache

protected static void clearDSCache()

Clears cache of DataSources (For Unit test)

getDataSourceFromJndi

protected static DataSource getDataSourceFromJndi(String dsName,
 Context ctx)
                                           throws NamingException

Since JNDI is supported different ways in different app servers, it's nearly impossible to have a ubiquitous way to look up a datasource. This method is intended to hide all the lookups that may be required to find a jndi name.

Parameters:

dsName - The Datasource name

Returns:

DataSource if there is one bound in JNDI

Throws:

NamingException

closeSilently

public static void closeSilently(Connection[] connections)

closeSilently

public static void closeSilently(Connection conn)

closeSilently

public static void closeSilently(Statement[] statements)

closeSilently

public static void closeSilently(Statement st)

Description copied from interface: DataSourceProviderInterface

Invalidate the named data source of respecting its type
