I had sesame triplestore installed on my computer and it was working fine. When I ran into trouble pertaining to CORS while using ajax for fetching data from the server, I tried modifying the web.xml file at C:\Program Files (x86)\Apache Software Foundation\Tomcat 7.0\webapps\openrdf-sesame\WEB-INF. For modification, I followed the instructions at http://software.dzhuvinov.com/cors-filter-installation.html.
I cut the file out to my desktop, edited the code, and then pasted it back to the original folder location to counter an 'access denied error'. After that, restarting the Tomcat server and going to http://localhost:8080/openrdf-workbench/repositories/NONE/server takes me to the 'Change Server' page. And I cannot figure out what the correct server URL is. http://localhost:8080/openrdf-sesame doesn't work. What do I need to change?
Thank you for responding.
Solved it! Just re-pasted the two .war files into the original location and they generated the web.xml files.
