I set up Sap NetWeaver 2004s (7.0) sp 11. I was able to connect and mobile device and downloads an application to it. The problem I'm having now is getting the mobile administrator to generate the sda file. I downloaded and packaged the sample application from the NetWeaver Mobile Development example. When I upload the war file I get an generated sda file that is empty. (zero bytes). Any ideas was is causing this problem. I search in the nwa and in SAP Gui for error messages but could not find any.
