RE: [equinox-dev] Using LIRc library in Equinox

Hi again,

I have got the Libjunixsocket.so and put it in the classpath path, but it is
does not work, either I have tried putting this library into the bundle,
using BUndle Native-Code in the Manifest, but I am not able to export from
Eclipse when I use this.

The idea is I have a LIRC packages, which were wraping into a bundle with
the Eclipse option, New Project--> Plug-in Projects--> Plug-in from existing
JAR archives. I use this bundle LIRCbundle as required bundle in my main
bundle.

I guess I would have to put the native libraries (Junixsocket.so) into to my
LIRCBundle, using the Bundle Native-Code header. The problem is that when I
use this I am not able to export the bundle without any problema shown. 

Any idea?

Thanks

Hi Mark,

I have tried wrapping the LIRC.jar libraries in a bundle, and adding like
Required-Bundle in the different Bundles' Manifest where they use this
classes. The problem is that I continue getting the same Exception.

I have looking the source code from LIRC packages and I found a static code
where I guess LIRC packages use JNI libraries, what Do I have to do with
this?


public class UnixSocketImpl {

	static {
		// Loads the JNI library from the directory of this class
		String libname = System.mapLibraryName("junixsocket");
		// uses getFile() instead of getPath() as getPath() is not
available in JDK1.2.2
		String libpath =
UnixSocketImpl.class.getResource(libname).getFile();
		System.load(libpath);
	}
....

}

How should I treat this code in order to adapt with OSGI? I mean, I have
tried launch a simple application using LIRC libraries and it worked fine,
but when I tried to use LIRC packages from OSGI I get :

java.lang.NoClassDefFoundError: Could not initialize class
org.lirc.socket.UnixSocketImpl.
....

I tried with -vmargs -Djava.library.path=path_to_lirc_libs

But nothing new appears

Perhaps, the question is easier, how do I have to do when I have JNI classes
in my bundles?

Thank you in advance

Hi,

just an idea. Maybe jlirc works with JNI? Maybe you have to give the library
path to the VM similar to subclipse?
Like: -vmargs -Djava.library.path=path_to_lirc_libs
