Thanks for the article! I was able to reuse Eclipse’s Workspace dialog instead of using another dialog. Here’s code snippet from my Application.java file:

import org.eclipse.ui.internal.ide.ChooseWorkspaceData;
import org.eclipse.ui.internal.ide.ChooseWorkspaceDialog;

public class Application implements IApplication {
public Object start(IApplicationContext context) {
Display display = PlatformUI.createDisplay();
Location instanceLoc = Platform.getInstanceLocation();
boolean isWorkspaceSelected = false;
try {
URL url = new File(System.getProperty(“user.home”), “workspace”).toURI().toURL();
ChooseWorkspaceData data = new ChooseWorkspaceData(url);

ChooseWorkspaceDialog dialog = new ChooseWorkspaceDialog(display.getActiveShell(), data, true, true);
dialog.prompt(true);

String selection = data.getSelection();
if (selection != null) {
isWorkspaceSelected = true;
data.writePersistedData();
url = new File(selection).toURI().toURL();
instanceLoc.set(url, false);
}
} catch (Exception e) {
throw new RuntimeException(e);
}

try {
//removeHelpExtension();
if (isWorkspaceSelected) {
int returnCode = PlatformUI.createAndRunWorkbench(display, new ApplicationWorkbenchAdvisor(display));
if (returnCode == PlatformUI.RETURN_RESTART) {
return IApplication.EXIT_RESTART;
}
}
return IApplication.EXIT_OK;
} finally {
display.dispose();
}
}
}

Thanks for the great article! It is always good to find a complete implementation for something when you are only looking for a starting point.

The only change that I made was to add another preference value that remembers if the app is restarting from a workspace switch. In the Application.start code, if that value is true then I reset it and set the remember variable to true so that the user does not get prompted for a workspace right after they already set the new one

Thank you so much for posting this article. I’ve been struggling with this for about a week and had about 80% of what you have here worked out, but that last 20% was killing me. Again, thank you for sharing your work!

Very good article. Thank you. Now I’m trying to set -data @noDefault through some config file (e.g. config.ini) but I can’t get it working. Do you have any idea how to do it? I tried osgi.instance.area=@noDefault but it doesn’t work.

Wow, an author who cares!
Thanks for the jar. I’ve missed TableLayout,
but MigLayout is becoming more familiar over time.
Great, I have my own workspace(s), thanks.
Now on to custom projects and the CNF.

Thanks for the heads up, seems LatticeLayout is gone. I've updated the post with a direct link to the jar that I uploaded to Hexapixel (which contains sources and javadoc too). Here's the same link: LatticeLayout Jar. I guess it's MigLayout from here on out.
