Satellite Tracker

A small and simple satellite tracking application. This application has been created as a tutorial to demonstrate how spring 3, jpa and vaadin can be combined to quickly develop web-applications. The project is derived from SpringApplication in the vaadin incubator.


Currently, only a subset of available satellite data has been extracted from When the application is started, the latest TLE data is retrieved from


mvn clean package
mvn jetty:run

firefox http://localhost:8080/sat-tracker


In order to get the application working in eclipse with the GWT development mode, some hacks had to be added:

  • src/main/webapp/WEB-INF/jetty-web.xml: promote slf4j to system classes
  • src/main/resources/META-INF/spring.handlers + spring.schemas: copy these files from spring-tx.jar
  • lib: added custom packaged orekit-6.0-SNAPSHOT-tn.jar with some bugfixes
