The error is related to your foodmart datasource connection. Please check its connectivity because it seems to be the reason of your issues!

I can create chart using stored DBs in demo but when use my Data set (mongodb- I had created a new JDBC datasource in server.xml and I had changed all knowage*/META-INF/context.xml -) it shows this error " Unable to load data from dataset test Please check dataset & widget config".

Please tell me what can I do exactly? Where must change? it wasts my time for a week!!!

You should have a look at knowage.log and figure out which is the actual error from the log file.
