This is a fork of the geoserver tjs community extension based on the excellent work of https://github.com/thijsbrentjens/geoserver/tree/tjs_2.2.x/

Show the release page to find the updated extension versions made by Antea(r)Group for DREAL Corse.

Original README from thijsbrentjens :

Table Joining Services extension

The community plugin TJS will add support for Table Joining Services v 1.0.0 to Geoserver. Code is based on code of GeoCuba/GeoMix, imported by Thijs Brentjens (for Geonovum) on request of GeoCuba/GeoMix. Support for WFS output and refactoring to imrpove WMS support has been done for Geonovum.

This extension is under development. Please read this carefully. Any feedback is welcome.

Features

The TJS extension adds TJS support to Geoserver (2.7.x at the moment). It adds TJS operations to join data and adds web administration options. The web admin allows for management / configuration of:

• spatial frameworks (spatial datasets to join data on) and non-spatial tabular data to be published in GDAS encoding
• pre-configured joins.

The TJS OGC webservice interface of this extension supports almost all TJS operations. It allows for example for:

• GetCapabilities
• getting data in GDAS encoding
• creating joins using JoinData
• output of joins as WMS layers, WFS featuretypes. The TJS extension has (some) support for SLD, but this is untested currently

The above features have initially been developed by GeoCuba/GeoMix. Geonovum has added WFS support and has rewritten parts of the source code.

Work in Progress

The TJS extension is still under development. It has not been tested extensively yet. Testers on different systems / platforms are welcomed. Please contact Thijs with any questions:

t dot brentjens at geonovum dot nl.

Among things to do are:

• support for management of joined output files and removing joins / clearing the cache after a pre-configured time
• user manual
• fix tests for the postgres connection of data stores, make it file-based

Related projects

For demonstraton and test purposes a basic tool is developed. This tool allows users to upload a CSV-file and join that to a spatial framework (spatial dataset)

See https://github.com/joostvenema/tjs-demonstrator for the demonstrator

The Geodetic institute of Slovenia has created support for TJS in it's STAGE client. A Javascript version is available here: https://bitbucket.org/ginst/jstjs/

Installation

The libraries for the TJS extension can be build from the community/tjs/ directory, see Compilation below.

Compilation

Follow the general build instructions of Geoserver. To build the TJS plugin seperately, go to the directory

src/community/tjs/

and build using the regular command:

mvn clean install -DskipTests

Note: tests will probably fail at the moment because of Postgres connections in some of the tests. Skipping the tests will help for now. This is a workaround, improve tests and test coverage is still necessary.

After compilation, copy the following jars to {geoserver}/WEB-INF/lib/ :

• net.opengis.tjs/target/net.opengis.tjs-{gt.version}.jar
• tjs/target/tjs-core-{tjs.version}.jar
• tjsdata/target/tjsdata-{tjs.version}.jar
• tjs-web/target/tjs-web-{tjs.version}.jar
• xsd-tjs/target/gt-xsd-tjs-{gt.version}.jar

Using Eclipse

To use the TJS plugin in Eclipse, follow the general guidelines of GeoServer but don't import the projects in Eclipse yet, http://docs.geoserver.org/2.6.x/en/developer/quickstart/index.html

Before importing the projects, you need to configure the TJS plugin for Eclipse as well:

To add the TJS plugin:

1. with a command line, setup the Eclipse project for TJS:

cd src/community/tjs/

mvn eclipse:eclipse

2. Now import the project Geoserver from file, as described http://docs.geoserver.org/2.6.x/en/developer/quickstart/index.html. You should see

3. Run configuration: After the first Run configuration with Eclipse, the TJS plugin needs to be added manually to the Run configuration. You can do this by going to Run > Run configurations... There, add the TJS-projects to the Classpath, as projects:

• net.opengis.tjs
• tjs
• tjsdata
• tjs-web
• xsd-tjs

4. Running Geoserver with TJS should work now. NOTE: at this moment, there seems to be an issue using Eclipse's Run functionality, especially with the data dir configuration for TJS.
