Method Detail

act

public Map act(Redirector redirector,
               SourceResolver resolver,
               Map objectModel,
               String source,
               Parameters param)
        throws Exception

Update a record in 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

Returns:

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.

Throws:

Exception - Indicates something is totally wrong

getUpdateQuery

protected String getUpdateQuery(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.

Throws:

ConfigurationException
