void	clearCache() This method clears the JNDI DS cache.
void	clearDataSource(java.lang.String dsName) This method clears the JNDI DS cache.
java.lang.String	getDSBoundName(java.lang.String dsName) Since JNDI is supported different ways in different app servers, it's nearly impossible to have a ubiquitous way to look up a datasource.

public BaseDatasourceService()

Method Detail

clearCache

public void clearCache()

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.

Specified by:

clearCache in interface IDatasourceService

clearDataSource

public void clearDataSource(java.lang.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.

Specified by:

clearDataSource in interface IDatasourceService

getDSBoundName

public java.lang.String getDSBoundName(java.lang.String dsName)
                                throws DatasourceServiceException

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 IDatasourceService

Parameters:

dsName - The Datasource name (like SampleData)

Returns:

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

Throws:

DatasourceServiceException

getDSUnboundName

public java.lang.String getDSUnboundName(java.lang.String dsName)

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 extract just the regular name of a specified JNDI source.

Specified by:

getDSUnboundName in interface IDatasourceService

Parameters:

dsName - The Datasource name (like "jdbc/SampleData")

Returns:

The unbound DS name (like "SampleData")
