For backwards compatibility, better performance with tiny numbers of features, and to support chaining across different data sources, joining is disabled by default. Kind regards, Ben.

I have made a screen shot of the parameters I am sending to the geoserver. It is working if I run this from Netbeans, but failed to work if I run from a jar file.

While everything is working when I run the application from within NetBean, I am not able to connect WFS - it always complain about the connection parameters. I am sure I used the identical connection parameters in both cases. You need to get some logging going, see the exact request being issued by your client, and what the GeoServer response is. Most of the time the request is actually missing some required element, GeoServer is quite liberal and accepts even broken requests up to a certain point, normally when you get the error something really fundamental is missing.
