Hello,

i have the following problem. My RCP needs a file from the java "ext"
directory. With the command -Dosgi.parentClassloader=ext my application
finds that what it need. In Windows* my programm runs with that parameter
correct, but under linux comes:
java.lang.UnsatisfiedLinkError: no swt-pi-gtk-3064 in java.library.path

Interesting, because if i do not use the -Dosgi.parentClassloader=ext
Parameter my application starts (but without functionality).

Then i give him all the librarys and linked them with -Djava.library.path=

Setting the OSGi parent loader is generally not recommend, because this
alters the classpath of every plugin in your application. If it's only
your plugin that needs the ext directory, you can specify this in your
plugin's MANIFEST.MF with the line:

Eclipse-BuddyPolicy: ext

This is much safer because only your plugin will be affected. See Help >
Help Contents and search for "buddy" for more details.
