problems with the workspace handling in RCP/Eclipse [message #639916] Thu, 18 November 2010 12:16 Go to next message

Dear Eclipse RCP people,

we are developing a product based on RCP and eclipse. We have some problems with the workspace handling:
• When starting the product the first time: it doesn't ask the user to choose the workspace. Instead it takes a default workspace : ./workspace.
• When use the function "switch workspace", it does restart
eclipse and add the entered workspace to the workspaces I can select
on "switch workspace", but it does not switch the workspace Sad

I tried a lot of things to solve this:
• -data @noDefault, to force the product to ask the user for a workspace, but it does not work (errorlog1)
( Dani (daniel_mergert@ch.ibm.com) said that, you should simply remove "-data", but that's no solution: in this case it is just creating a default workspace)
• Set the workspace when the product is starting (code2) this
is working, but it's not a nice solution
• Many other things without any positive result.

What to do?
• Maybe using a different application super class or
interface.
• ...

Thanks a lot,

Best regards,
Nico Stieler

code2:
public class Application implements IApplication {

/* (non-Javadoc)
* @see org.eclipse.equinox.app.IApplication#start(org.eclipse.equin ox.app.IApplicationContext)
*/
public Object start(IApplicationContext context) {
setupLog4j();

Display display = PlatformUI.createDisplay();

//this solution does not work Sad

String fileName = "C:\\Users\\xxx\\out.txt";
BufferedWriter out = null;
Location instanceLoc = Platform.getInstanceLocation();

URL url = promptForInstanceLoc(display);

if (url != null) {
try {
instanceLoc.set(url, true);
} catch (Exception e) {
e.printStackTrace();
}
}
try {
int returnCode = PlatformUI.createAndRunWorkbench(display, new ApplicationWorkbenchAdvisor());
if (returnCode == PlatformUI.RETURN_RESTART) {
return IApplication.EXIT_RESTART;
}
return IApplication.EXIT_OK;
} finally {
display.dispose();
}
}



private URL promptForInstanceLoc(Display display) {
Shell shell = new Shell(display);
DirectoryDialog dialog = new DirectoryDialog(shell);
dialog.setText("Select Workspace Directory");
dialog.setMessage("Select the workspace directory to use.");
String dir = dialog.open();
shell.dispose();
try {
return dir == null ? null : new File(dir).toURL();
} catch (MalformedURLException e) {
return null;
}
}

At least the default eclipse.exe asks for the workspace.

Hi Dani,
How can this help me?
We are trying to create a product based on RCP using some eclipse packages.

everything works fine, except of the workspace.

what kind of information do you need to help me?

best regards,
Nico

Hello everybody,

I just found something on http://wiki.eclipse.org/FAQ_How_do_I_run_Eclipse%3F:

Quote:
The first time the eclipse command is executed, the platform creates a workspace directory, such as eclipse/workspace. The workspace will contain all your projects, along with private metadata computed by various plug-ins.

In Eclipse 3.0, you are prompted to choose a workspace location on start-up. Previously, the platform stored the workspace in the Eclipse install directory by default.


I am using 3.5.2 as target plattform. What could be wrong that I doesn't get promted to choose a workspace?

  • wrong settings
  • missing configuration file
  • others

Best Regards,
Nico
