getDataSource

public DataSource getDataSource(String dsName)
                         throws DatasourceServiceException

Description copied from interface: DataSourceService

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.

Specified by:

getDataSource in interface DataSourceService

Parameters:

dsName - The Datasource name

Returns:

DataSource if there is one bound in JNDI

Throws:

DatasourceServiceException

getDSBoundName

public String getDSBoundName(String dsName)
                      throws DatasourceServiceException

Description copied from interface: DataSourceService

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, and return the actual bound name.

Specified by:

getDSBoundName in interface DataSourceService

Parameters:

dsName - The Datasource name (like SampleData)

Returns:

The bound DS name if it is bound in JNDI (like "jdbc/SampleData")

Throws:

DatasourceServiceException
