Hi again, and thank you very much for your ideas,
I have been for trying to solve this problem for 5 days and I do
not get the solution.
I am going to explain the steps in order to show what I have
been doing so that perhaps it would be possible to find a mistake in my
process.
I am working compiling my classes in Eclipse in Windows XP and
exporting my bundles with the options Export from Eclipse, so that I get a .jar.
Then I use this jar files and put them in another machine working in Ubuntu,
where I launch Equinox.jar framework in CONSOLE MODE.
Firstly I tried to relate LIRC packages with the bundle which
uses these packages through I got the LIRC packages source from JLIRC website,
creating a new bundle and exporting these packages so that other bundles which
want to use LIRC classes can do it (by importing these packages)
I got java.lang.NoClassDefFoundError:
Could not initialize class org.lirc.socket. UnixSocketImpl.
In order to solve this problem I have also tried to wrap LIRC
packages in a new bundle, and adding Require-Bundle header to the manifest in
those bundles which need to use LIRC classes.
I add libjunixsocket.so and junixsocket.c to the root where I
have my jar files (bundles jar files), also I am launching the Equinox by
console with the next command: -vmargs –Djava.library.path=path_where_libjunixsocket.so
is.
It is odd because the first time that I launch the framework
without having the bundle which uses LIRC packages installed, I got when I
start this bundle: java.lang.exceptionininitializererror: in the class org.lirc.socket.UnixSocket
and other times I got java.lang.UnsatisfiedLinkError: Can’t load library:
/org/lirc/socket/libjunixsocket.so. but if I have installed this bundle and I
launch again Equinox framework I continue having ava.lang.NoClassDefFoundError:
Could not initialize class org.lirc.socket. UnixSocketImpl.
It is strange because I have tried with a simple example in Java
without OSGI and the LIRC application worked fine.
Any idea?
Thanks

I am aware of the following Bundle-NativeCode
bugs in PDE. You may have stumbled into another one. Please open a bug against
PDE.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=285229
https://bugs.eclipse.org/bugs/show_bug.cgi?id=284784
Another option is to just put the library at the root directory of your bundle.
Equinox will search for it by default without and Bundle-NativeCode header.
(Note this is legacy behavior of Eclipse and not OSGi spec'ed behavior).

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
