WORKING WITH THE SOURCES OF THE SAPEDITOR
=========================================

To simplify work with the sources of sapeditor, a complete project is provided under source control. This is located in "sape/src/sapeditor". To be able to work with this project, the following steps must be executed:

1.) Install some version of the eclipse sdk >= 2.1.1, which is downwards compatible to the stated version.
2.) Import the project by selecting "Import" from the "File" menu, then choose "Existing Project into Workspace" and provide the path to the sapeditor source project.
3.) Define the variable "T_DRV" which is being used in some path entries. This can be done by selecting Window->Preferences->Java->Classpath Variables->New and then providing name ("T_DRV") and path, the drive letter of the used view in our case ("X:\" or "Y:\", for example).
4.) In Window->Preferences->Plug-in Development, select "Target Platform" and press the "Select All" button to make the eclipse core plugins available to the sapeditor plugin.
5.) Select Window->Open Perspective->Plug-in Development to get all the interesting windows for working with the source.
6.) Start sapeditor in debug mode by selecting Run->Debug... or (later on) just pressing the F11 key. The former leads to a dialog window in which the entry "Run-time Workbench" should be selected and, by pressing the "New"-button, a new debug instance should be created if non is already existent. Enter the following line as "VM Arguments", the Y of the example replaced by the drive letter of the used view:
-Xbootclasspath/p:"Y:\gpf\tools\lib\java\xmlParserAPIs.jar";"Y:\gpf\tools\lib\java\xercesImpl.jar"
Press then "Debug", and the editor should open as usual.

Make use of the Eclipse Environment and the Java SDK as you see fit. For further details about Eclipse and how to use it, see the online help in the Help menu.

Good luck :-)
