Returns configuratoin management entry that contains a Map with key-value pairs read from the database based on the sql specified. The steps are: first database connection is established by looking up the database connection in JNDI based on JNDI name, JNDI Context factory if provided and other parameters as provided in cofiguration description. Second sql provided is executed against the database connection and lastly the results are read based on the columns provided in the configuration.

Specified by:

getConfigurationManagementEntry in interface ConfigEntryParser

Parameters:

key - configuration management key

fileUrl - file url is null, since database configuration is not file URL based.

Returns:

Configuration management entry.

Throws:

ConfigurationManagerException - if an error occurs while parsing an entry.

validateParameters

protected void validateParameters(java.lang.String key)
                           throws ConfigurationManagerException

Validates that key, jndi name, sql, etc are not null parameters

Overrides:

validateParameters in class AbstractJndiParser

Parameters:

key -

Throws:

ConfigurationManagerException
