There are 3 ways to specify the splash screen: -showsplash,
osgi.splashLocation and osgi.splashPath.
Order of precendence is as follows:
1) -showsplash
this is interpreted by the native launcher, it displays the native
"early" splash screen before starting the vm. This requires a bitmap on
the disk (ie in a folder shaped bundle).
There is some detail on the wiki
http://wiki.eclipse.org/Equinox_Launcher#Command_line_arguments regard the
possible values here.
If -showsplash is specified to the launcher, and a bitmap is found
there, then this will cause the property osgi.splashLocation to be set
with the path to that bitmap.
2) osgi.splashLocation (in config.ini or system property). Interpreted
by Main, this is a path to the bitmap on disk
3) osgi.splashPath (in config.ini or system property). Interpreted by
Main, is a url to a bundle
platform:/base urls are resolved relative to osgi.install.area. I
don't recal if p2 is setting this, if it doesn't then osgi.install.area is
based on the location of the equinox.launcher jar.
file: urls would also work here, absolute urls being the best,
(see bug 263280 for relative urls).
When the final segment is something like "org.eclipse.platform",
Main is just searching the disk for the highest version
org.eclipse.platform_version, it doesn't know which bundles are actually
installed into the running system (ie bundles.info)
Once a bundle is resolved, we look inside it based on the current
osgi.nl value, and we also support jars here (the bitmap is extraced and
placed under the configuration area).
platform:/base is probably your best bet, however bundle pools may
complicate this depending on how p2 manages osgi.install.area, and whether
or not the splash bundle is colocated with org.eclipse.equinox.launcher

[equinox-dev] Showsplash vs SplashPath
Tom (and others),
What is the difference between the showsplash and splashpath parameters
(properties)? I am working on the publisher for a .product file, and I am
trying to figure out what to do with the splash screen. PDE export
appears to use splashPath for the splash screen, and if the bundle that
contains the splash screen is "org.foo", PDE export wold generate:
osgi.splashPath=platform:/base/plugins/org.foo
Should p2 just use the prefix platform:/base/plugins? Or is this
something that will be determined at install time? (i.e. does a shared
install need a different prefix)?
cheers,
Ian
