To add a web service go to the TOMCAT-HOME directory (the directory where you installed Tomcat), open the file ApplicationResources.properties in the webapps/OwlQlWebApp/WEB-INF/classes directory. The first entry in this file should look like:
wsNames=http://localhost:8080/RacerManager-0.2/services/OwlQlService
You can add another OwlQlWebService offered by a different RacerManager installation: e.g.
wsNames=http://localhost:8080/RacerManager-0.2/services/OwlQlService,http://remoteserver:8090/RacerManager-0.2/services/OwlQlService
The web services listed here must be seperated by a comma. Afterwards you must redeploy the OwlQlWebApp using the Tomcat Administration Console (or you can completely restart Tomcat, if other applications running on suffer form this).
To add more sample queries or frequently used queries to the list of sample queries save a query in a file. The file must have the extension "xml". Copy the file in to the TOMCAT-HOME/webapps/OwlQlWebApp/samples directory. All files found in this directory are listed in the sample queries list. Finally redeploy OwlQlWebApp.
