Are you using SWT on top of Equinox or another OSGi Framework implementation? I would not expect issues on Equinox because we should be able to find the SWT libraries without the need of Bundle-NativeCode header. If you are seeing this issue while running on the Equinox framework then please open a bug against RT->Equinox->Framework (https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Equinox) and give steps to reprodice. Note that you will need a different SWT fragment for each arch/os that you want to run SWT on because each SWT fragment contains the necessary native library for a different platform. Also note that updating bundles with native code is always a dicing situation in OSGi. Java VMs are notoriously bad at unloading native libraries loaded by custom class loaders (such as OSGi). Each time you update such a bundle that has loaded the native code you are likely leaving behind a loaded library in memory that probably will not go away. Eventually you WILL run out of memory.

And my problem is solved by using Bundle-NativeCode. Thanks, -Vidya, From: [email protected] [ mailto:[email protected]] On Behalf Of David Conde Sent: Thursday, August 27, 2009 2:30 PM. To: 'Equinox development mailing list' Subject: RE: [equinox-dev] Update/uninstall SWT application in Equinox gives UnsatisfiedLinkError Hi,: I do not know if SWT uses native libraries, if it uses then you should include them in Manifest.MF with the Bundle-NativeCode: header, you can also try to fix the java.library.path in the command line with your native library path, when you launch Equinox. I got a similar Exception because I could not load a native library in Ubuntu. Regards David De: [email protected] [mailto:[email protected] ] En nombre de Vidya Vadke Enviado el: jueves, 27 de agosto de 2009 10:50 Para: [email protected] Asunto: [equinox-dev] Update/uninstall SWT application in Equinox gives UnsatisfiedLinkError Hi, I am trying to run an SWT application in OSGi environment. Install/start bundle works fine. But when I update the bundle or try to uninstall-install and start again, I get java.lang.UnsatisfiedLinkError - no swt-win32-3550 in java.library.path. I have tried putting swt.jar in classpath, extracting swt.jar and putting swt related dlls in windows path, also in jre/bin directory. Still uninstall-install works for the first time. If is try the same once more, it again gives the same error. Any help towards solving this problem would be appreciated.
