DB Data Store for Fess Java CI with Maven

Overview

DB Data Store is an extension for Fess Data Store Crawling. It crawls the rows returned by an SQL query over a JDBC connection, turning each row into a document.

Installation

Install it from the Fess admin UI, under System > Plugin, or place the jar manually:

  1. Download fess-ds-db-X.X.X.jar from the CodeLibs repository.
  2. Copy it to $FESS_HOME/app/WEB-INF/plugin (/usr/share/fess/app/WEB-INF/plugin for a package install).

The JDBC driver for your database is a separate download. Copy its jar to $FESS_HOME/app/WEB-INF/lib or $FESS_HOME/app/WEB-INF/env/crawler/lib, then restart Fess. Without it the crawl fails with The JDBC driver ... is not on the crawler classpath.

Documentation

See Database Data Store for the parameters and configuration examples.
