Just an FYI, in case folks didn't look at the readme and find that using vector layers (in the V2 API) raises an error with 188.8.131.52.1.
With this patch the mapviewer data server (which serves up themes from data sources aka vector layers) is restricted by default.
The mds.xml file (in WEB-INF/conf/) must be modified to explicitly specify, and enable, data sources and themes from those data sources.
MapViewer must be restarted after modifying and saving the mds.xml file.
jayant its not clear what that error means "data layer does not support streaming see server.log for info" unless you read the readme or your post above
It would be helpful to add more descriptions to the errors thrown something like: "data layer does not support streaming please edit mds.xml" in the server.log or in the alert thrown in the js
I had a fair bit of angst on this for past 24 hours
