Re: [rap-dev] How to start RAP design demo in local workspace

[Ivan Furnadjiev <ivan@xxxxxxxxxxxxxxxxx>]

Hi Christian,

follow the steps bellow:
1. Download and install "Eclipse IDE for RCP and RAP Developers" from [1].
2. Create a new workspace
3. Set RAP Runtime as target platform. Use p2 software site or zip file 
[2] . Don't forget to select examples/demos.
4. Import examples bundles as source bundles from "Plug-ins" tab:
Workbench demo: "org.eclipse.rap.demo"
Controls demo: "org.eclipse.rap.demo.controls"
Examples demo: "org.eclipse.rap.examples", 
"org.eclipse.rap.examples.pages", 
"org.eclipse.rap.filedialog.demo.examples", 
"org.eclipse.rap.nebula.widgets.grid.demo.examples", 
"org.eclipse.rap.nebula.widgets.richtext.demo.examples".
5. You can find the corresponding launch configurations in "launch" 
folder. For example "org.eclipse.rap.demo\launch\RAP Workbench Demo 
(Business).launch". Just start the demo from there. That's it.
