SimpleEFA

A simplefied wrapper around EFA's XML interface

Requirements

• ant
• tomcat installation
• servlet-api.jar has to be in your CLASSPATH

Installation

This is a Java-Servlet which can for example be run in Tomcat. A pre-built WAR can be found in the releases.

To create a distributable WAR-File yourself checkout this repo and type

ant war

and upload the generated build/simpleefa.war to a live Tomcat server.

Configuration is done in in war/WEB-INF/simpleefa.properties. Important: you have to adjust common.simpleefaurl in the properties file to a valid SimpleEFA backend URL, for example like this:

common.efa_url = http://www.efa-bw.de/nvbw/

Request Restrictions

A poor-man's security mechanism to prevent mass-requests is built-in and can be configured via common.ipwhitelist and common.maxconnectionperhour.

ISO-Encoding

Most EFA-Installation expect request strings to be ISO-encoded. However, there are some newer installations that expect UTF8-encoding. To disable the default ISO-encoding of request parameters, set common.isoencoderequests = 0 in the properties file.

JSON-Output

The default output format is XML directly rendered from the result of an XQuery query. However, you can enforce JSON format by setting the GET parameter format=JSON, for example like this:

http://localhost:10080/simpleefa/stationname?station=stuttgart%20hauptbahnhof&format=JSON

An optional GET parameter callback will wrap the outputted JSON to make it into JSONP:

http://localhost:10080/simpleefa/stationname?station=stuttgart%20hauptbahnhof&format=JSON&callback=mycallback
