Splash screen for Virgo kernel? [message #848807]

Hello all.

I am wondering if it is possible to put up a splash screen while my Virgo kernel is starting up as part of my desktop application.

I am thinking of something similar to what a full blown Virgo server does.

TIA,
B.

You may try two approaches:

Eclipse launcher's --showSplash <bitmap> [1][2]
Java SE 6 [3][4]

Thanks Hristo.

If I use the Java 6 option, how do I get it to work with OSGi? Do I create a bundle jar and deposit it in the pickup directory?

I know, I am probably being thick again...

The Eclipse launcher will most probably require you to add some entries in config.ini (provided you use 3.5) or Virgo launch properties (for 3.0.2). This seems to me a better approach since you may build a bundle and have it accessible by the OSGi framework either in config.ini or in launch properties.

The Java 6 splash screen approach will require adding splash screen argument in dmk.bat/sh and then adding the JAR with the splash screen in Virgo's class path since the JDK is not an OSGi framework Smile

Please have in mind that I haven't tried these myself so it's all just theory and in practice more work may be required to get things working.

Thank you for the details.

Unfortunately I am running an earlier version of Virgo, so I cannot use the Eclipse based approach.

I have tried the Java approach, but for some reason I cannot get it to work within OSGi (a splash screen in a plain Java app works without issues).

So my fallback at the moment is to have a bundle that just contains a borderless frame acting as the splash screen and to have it start up as soon as possible at OSGi container startup. The splash screen gets shown later than I would like, but...

Thanks again,
B.

Hello again.

I have now updated my Virgo Kernel to 3.5 and I am trying to use config.ini to define a splash screen. However all my efforts have been for nought so far. In config.ini (located in the configuration dir of my Virgo installation), I have added the following line:

osgi.splashPath=file\:configuration

and I have added a file called splash.bmp in the configuration directory (for testing purposes). A splash screen is not shown and no errors are produced at all.

Ideas?

TIA,
B.
