can i publish my GIS data on some server other than ArcGIS Server ?

[MustafaNoor]

queryTask = new esri.arcgis.gmaps.QueryTask("http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/3");

The above line of code uses Esri Sample Server. Similarly i want to use same code but with different server. e.g, http://93.20.10.12/demo server. (this is our demo server where i put my shapefiles)

Is it possible ? if not, Is there any other alternative ?

This is not possible. which have purchased ARCGIS Server from Esri to load over GIS data.

So, you want to use your own ArcGIS Server service in the javascript API?  If that is what you want to do then yes you can use your own service, just make sure that the spatial reference matches the map.

However, if you want to use a non ArcGIS Server service then you will need to get the data back and create a graphics layer from the data.
