public class install
extends javax.servlet.http.HttpServlet

Servlet to perform Astro-Online installation.

Astro-Online needs a database to store astrological as well as configuration data. This installation procedure creates all necessary tables and imports all necessary data.

The function doRequest handles the installation steps and makes sure the installation proceeds in the right sequense.

The function importTable is written to specifically import Astro-Online data. It creates the Astro-Online tables from the sql installation files and reads the data from the installation xml files. All installation files were generated with the mysqldump utility without any manual changes afterwards.

The function importTable generates insert statements with the data subtracted from the xml files. To recognize the date type of a column and whether nulls are allowed, the "show column" mysql statements is used. This function importTable does not cover all possible imports. Developers who want to use this code in other projects must be carefull to test all datatypes used in their project.

Finally the function importTable handles only int datatypes differently than the rest! (e.g. no quotes around values for int types and quotes for all others)

The installation utility is still under development...
