What is the data source you are trying to display? That is, what was the original format, and how do you have it set up in your geoserver instance? –  BradHards Dec 9 '12 at 22:59
thanks a lot for ur quick reply , my data source is POSTGIS table –  SIslam Dec 9 '12 at 23:58
Please explain what you inserted into the table, and how. –  BradHards Dec 10 '12 at 0:01
I think there might be some issue with the spatial reference. In addition, how many features do you have in total? –  Devdatta Tengshe Dec 10 '12 at 3:23
@msi_g I was asking about the number of records or rows in the thana table. –  Devdatta Tengshe Dec 10 '12 at 5:48
