null pointer exception in demo app

Hello,

I am running the demo app, following the directions from here.

https://cwiki.apache.org/confluence/display/SIS/Getting+Started+With+SIS

mvn jetty:run

Putting in this data


Point Radius:

Latitude: 0
Longitude: 80
Radius: 400km



I am getting a Null Pointer exception.



Do I need to do anything else to get this to work?


Thanks,


Travis

Then, maybe we should just replace the "getting started" instructions in 
the README by a link to the wiki?

All,

I expect that the README is really out of date for the web app. I added the
Jetty server config to pom.xml about a year ago and it was working then.
There has been some serious refactoring since then so the docs probably
need to be updated to reflect that.

Adam

I'm not yet familiar with the sis-webapp module, but the exception seems 
to be caused by a "qIndexPath" parameter not found. I noticed that the 
README file in the root of SIS project seems to contains slightly 
different instructions than the one on the wiki page (thanks for 
updating the wiki by the way!). Maybe it would be good to compare them.
