Method Detail

clearCache

public void clearCache()

clearDataSource

public void clearDataSource(String dsName)
This method clears the JNDI DS cache. The need exists because after a JNDI connection edit the old DS must be removed from the cache.

getDataSource

public DataSource getDataSource(String dsName)
                         throws DatasourceServiceException

Parameters:
dsName - The Datasource name
Returns:
DataSource if there is one bound in JNDI
Throws:
NamingException
DatasourceServiceException
