I am getting following error on
Cannot create the in-place editor
This is probably because there is no OLE editor registered against t
I'm using 3.5 so things could be different. Window->Preferences->General->Editors->File Associations.
Add *.xls and add Associated Editor (from this window you can select external programs to open with)
I think you should be able to open the excel file inside and eclipse editor, but it looks like the OLE is not working on your system for some reason.
first check the system editor available or not. if available right click on xls file and click on open with system editor. if not available follow bellow steps.
eclipse-->help-->Install new software-->search for editor and download and restart the eclipse. After restart the eclipse right click on xls file and click on open with system editor.
