21.  SAP AG 2002, Sam Tingleff 21 Goal: Combine the Advantages of Both Approaches Provide one frame for all tools and as integration point for all infrastructure components Provide convenient integrated infrastructure environment to support large scale application development Preserve principle of local IDE Local editing support Offline development Optimal support for standard and SAP technologies Logically structured presentation of all Design Time Objects Graphical editing support

22.  SAP AG 2002, Sam Tingleff 22 IBM’s Eclipse Is the Foundation of SAP’s Java IDE Open Source project "donated" by IBM Eclipse is itself written in Java Eclipse is only a framework: Everything is a plugin! Formally defined Extension Points and Plugin dependencies Very small kernel (Platform Runtime): The framework itself is implemented as a set of plugins Own UI approach (SWT / JFace) Workbench plugin as generic framework for any tool Complete Java (J2SE) IDE comes with Eclipse  Set of plugins  Open Source Eclipse is the basis of IBM‘s IDE WSAD Many vendors are providing Eclipse plugins: Strong Industry drive

23.  SAP AG 2002, Sam Tingleff 23 Eclipse: Projects Multiple projects can be opened at the same time Project dependencies can be declared Workspace principle: a workspace defines the scope of accessible resources No workspace switch at run time
