xe3에서 EIPABSTRACTOR 에러 처리

Where is this error coming from? In the example we are using DataSnap TCP/IP connectivity, which is internally implemented using Indy framework. The Indy implementation has changed between XE and XE3 versions, so there are little changes needed. On the server it is necessary to add "IPPeerServer" to the interface "uses" clause in the "ServerContainerUnit1" and on client we need to add "IPPeerClient" to the interface "uses" clause in the "ClientModuleUnit1". In fact the IDE can add these entries automatically. Just put the cursor somewhere in the "uses" clause of these two files and when you press "Enter" correct entries will be added for You! Cool:-)

I have also added a project group file "SimpleCalcGrp" and updated forms’ captions to "XE3".

uses절에 IPPeerServer를 추가하면 해결.
