Hi,
I already tried sth like that. Right after creating Display before
workbench is created in my IPlatformRunnable class i tried to set instance
Directory.
All i got was an exception. Perhaps anyone else tried this ?
my run methode :
Display display = PlatformUI.createDisplay();
Location instanceLoc = Platform.getInstanceLocation();
instanceLoc.release();
URL url = promptForInstanceLoc(display);
if (url == null) {
return IPlatformRunnable.EXIT_OK;
}
instanceLoc.setURL(url, true);
try {
int code = PlatformUI.createAndRunWorkbench(display,
new BXTPWorkbenchAdvisor());
// exit the application with an appropriate return code
return code == PlatformUI.RETURN_RESTART ? EXIT_RESTART :
EXIT_OK;
} finally {
if (display != null) {
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;
}
}
and the exception :
!ENTRY org.eclipse.osgi Nov 30, 2004 17:05:11.432
!MESSAGE Application error
!STACK 1
java.lang.IllegalStateException: Cannot change the location once it is set.

This is because when you started your application you specified a value
for the workspace (this is in one of the tab of the "eclipse application
launchers"). To avoid the problem replace the value by "@noDefault".
