Writing to DOS Console for Headless RCP [message #460184]

Hi,

I originally posted this in the eclipse.newcomer group, but I think this is
a better group for this particular post. Sorry about the double post!

I have to create a RCP Application which when invoked from the command-line
with a "-headless" argument, doesn't create the Workbench and simply writes
out a few lines to the system console and exits.

Questions:
(1) When I invoke my RCP from a DOS command shell, it seems to create a NEW
console to which the System.out.println() writes to. I want it to write to
the same command shell used to launch the RCP by the command-line. How can I
do this?

(2) My RCP has a splash screen which I want to hide when the user passes in
"-headless" as a command-line argument. Is there any way to do this?

Thx!

Hi.

I know that there is a "-noSplash" command line argument, is that
something you can use? Also check out Platform.endSplash().

Hope that helps,
Ali.

Forgot to add: also check out "-consoleLog" command line.

Which java do you start with? It might be that you need to run with
java.exe as opposed to javaw.exe in your -vm argument.

Paul, I use java.exe. Here's my command line:
myapp.exe -vm "C:\Program Files\Java\jdk1.5.0_09\bin\java.exe" -headless

Based on Ali's suggestion in an earlier reply, I tried -consoleLog, that
didn't seem to work.

Thx,
Ameya

Thx Ali. The "-noSplash" does work; however I'm trying to dynamically hide
the splash screen whenever the user passes in "-headless", so I thought the
Platform.endSplash() would be what I would need, but it doesn't seem to
work. Do I just call it as it is, or do I need to get a reference to the
Platform from somewhere?

I still haven't solved issue #1 below :( -consoleLog doesn't seem to work.
Ideas anyone?
