the class SolutionHelper method execute.

/**
 * Runs an action sequence. This method uses the base URL set by the Application Context
 *
 * @param description
 *          An identifier for this process. This is used for auditing and logging purposes only.
 * @param session
 *          The user session that is requesting this execution. This is used for auditing and logging and also
 *          can be used in action sequences (for example to filter data)
 * @param actionSequence
 *          Path to the action sequence file
 * @param parameters
 *          Parameters to be passed to the action sequence
 * @param outputStream
 *          The output stream for content generated by the action sequence. Can be null.
 * @param execListener
 *          An execution listener for feedback during execution. Can be null.
 * @return
