Abstract: Methods and systems for a remote user interface and remote debugging in a computer system comprising an application server and at least two client systems are provided. A first client operated by a user wishing to debug a remote application running between a second client and the application server registers at the application server. The application server invokes a user interface at the first client from the application system, based on information provided at registration. Using the present invention, in an SAP environment, developers can use the user interface for interactive actions and also debug running of an application, whether on an SAP or non-SAP system, from a remote location.
