Rogue Wave JViews Maps Sample: Connecting to IBM DB2 and Informix Databases

Description

This sample shows how to use Rogue Wave JViews Maps with IBM DB2 and Informix databases

How to Use the Sample

To be able to import DB2 or Informix Spatial layers, you must have access to a database server with the Spatial Extender (DB2) or Spatial Datablade (Informix) installed and configured. You must also have an account with read permission on the tables you want to access.
For more information, contact your database administrator who can help you define the correct connection parameters.

How to Run the Sample as an Application

This sample can be run as an application. The installation directory contains an executable JAR file, ibmdb.jar, that allows you to execute the sample with a double click from a file browser. Note that if you are using Internet Explorer, you can open the installation directory and execute the JAR file from the browser. This technique may not work in other Web browsers.

Alternatively, you can run the sample application from the command line. First check that the Ant utility is properly configured. If not, see the instructions on how to configure Ant for Rogue Wave JViews.

Then, go to the installation directory of the sample and type:

ant run

Loading from an IBM Informix table

Detailed Description

This sample shows how to use Rogue Wave JViews Maps with IBM DB2 and Informix databases.

This sample provides source code that shows you how to:

Import vector data from a DB2 database into Rogue Wave JViews through a selection dialog.
Import vector data from an Informix database into Rogue Wave JViews through a selection dialog.
Import vector data from a DB2 database into Rogue Wave JViews using an application-coded database connection and table specification.

The specific parts of the DB2 and Informix sample UI are:

: Loads a spatial layer using an DB2 data source ( IlvDB2Datasource ).

: Loads a spatial layer using an Informix data source ( IlvInformixDatasource ).
This sample uses the packages ilog.views.maps.datasource.ibm , ilog.views.maps.datasource.ibm.db2 , and ilog.views.maps.datasource.ibm.informix .

About IBM Spatial Database Support

The IBM relational database products DB2 and Informix both have features that provide the ability to create a database table with a geospatial type such as point, line, or polygon. The values in a spatial column can be created by importing from a source, such as the ESRI shapefile de-facto standard, or by populating the database with an SQL constructor function that uses numeric values, geometric shapes, well-known text, or well-known binary representations.
A set of spatial SQL functions and predicates that implement the Open Geospatial Consortium (OGC) specification allow you to create SQL queries including operations like "distance", "within", and "intersects between" spatial values.
For more information about these capabilities, refer to the DB2 or Informix online documentation and the IBM Spatial Web site .
