Java jni for libjingle

[Xiaohu Li]

Hi all,

I have two questions regarding libjingle.

1) Java lib is https://code.google.com/p/libjingle/source/browse/trunk/talk/app/webrtc/java/src/org/webrtc/?r=363 . So is it ONLY for Android?

2) If it is not just for Android, please continue to read this post. I am using Mac OS and wrote a small java application (regular java, not Android) using java lib mentioned above. I can compile it successfully but have runtime linkage error:

***************************************************************************************************************************************

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jingle_peerconnection_so in java.library.path

at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1886)

at java.lang.Runtime.loadLibrary0(Runtime.java:849)

at java.lang.System.loadLibrary(System.java:1088)

at org.webrtc.PeerConnectionFactory.<clinit>(PeerConnectionFactory.java:39)

...

***************************************************************************************************************************************

The question here is that how I can make use of Java library based JNI? How can I resolve this runtime linkage error?

Please advise. Thanks,

Xiaohu

The Java library also works in desktop JVM in linux, e.g. how the unittest is written (PeerConnectionTest.java).  You might find the launcher script we use on linux to be instructive (libjingle_peerconnection_java_unittest.sh), as well as the README that explains how to build/run it.

I suspect you're missing something like

export LD_LIBRARY_PATH=`pwd`

Cheers,

Thank you a lot, Ami.

I managed to run Java class using Libjingle Java library on Ubuntu server 12.04.

I think the error is due to the missing .so file right ?? It is clearly saying that "no jingle_peerconnection_so in java.library.path". So i hope the "so" library file is missing which is the reason of this error .. ??

Please clarify if not.

Hi Xiaohu,

habe you been able to solve your problems with the usage of the native framework in a desktop Java application?

Do you have any tips for me where to start?

Best,

Lars
