JavOO

JavOO : Java Odbc for Office.

Introduction

JavOO is a small multithread secure server written in Java and working on Windows platform.

It allows you to share MSAccess and MSExcel resources, which will be accessed through the native ODBC driver of Windows.

Download

The actual version is beta 1.0 .

You can download the Windows installer here.

Installation

Double-click on the file JavOOsetup.exe and follow the instructions.

By default the program will be installed in the directory C:\Program Files\JavOO\ .

Configuration

Now that you've installed JavOO, you need to add your Excel and/or Access resources.

In the install directory you'll find a file named javooconfig.xml. This file is in XML format. It defines a root element serverconfig in which an element resources is defined. That is in this latest element where you will define your own resources. Some example resources are already defined to show you how the resources should be declared in order to be accessible through the server.

You can edit this file with you favorite text editor.

Excel file

  <excel_resource name="testExcel" 
                   filepath="C:/path/to/the/file.xls" 
                   sheet="sheet" 
                   selection="selection" 
                   user="username" 
                   password="userpassword" 
                   readonly="true" />

• The declaration of an Excel resource is a bit specific, let's see:
  • An Excel file has one or many sheets, each one has a specific name, depending on the localisation of your computer, ie "Feuil1" in french, "Sheet1" in english, "Tabelle1" in german, etc. These names can be edited. Because many sheets can be accessible, you will have to define the proper name in the sheet attribute of the Excel resource.
  • Now the tricky part: the selection is a specific zone of you sheet, containing the header line of the table and it's content. Here is an example of a selection.

Name	Age	Gender
Bob	30	Male
Jane	28	Female
Cindy	45	Female

The nice part here is that you can define one or many selections in the same sheet, but you will have to declare as many resources as the number of selections you want to be accessible.

How to create a selection in Excel

1. First select a zone of your sheet containing

Access file

  <access_resource name="testAccess" 
                    filepath="C:/path/to/the/file.mdb" 
                    user="username" 
                    password="userpassword" 
                    readonly="true" />

• Usually people do not define username and password for Excel files, so if your file doesn't have this kind of protection you can

leave them blank.
