Method Detail


public Map act(Redirector redirector,
               SourceResolver resolver,
               Map objectModel,
               String source,
               Parameters param)
        throws Exception
Select a record from the database. This action assumes that the file referenced by the "descriptor" parameter conforms to the AbstractDatabaseAction specifications.

Specified by:
act in interface Action
resolver - The SourceResolver in charge
objectModel - The Map with object of the calling environment which can be used to select values this controller may need (ie Request, Response).
source - A source String to the Action
param - The Parameters for this invocation
Map The returned Map object with sitemap substitution values which can be used in subsequent elements attributes like src= using a xpath like expression: src="mydir/{myval}/foo" If the return value is null the processing inside the element of the sitemap will be skipped.
Exception - Indicates something is totally wrong


protected String getSelectQuery(Configuration conf)
                         throws ConfigurationException
Get the String representation of the PreparedStatement. This is mapped to the Configuration object itself, so if it doesn't exist, it will be created.
