Pinned topic How to load native libraries?

‏2013-12-12T15:37:18Z |

Hi all,


on WAS Liberty profile, I would like to use a jar file that need a specific dll file. I cannot change the jar file. If I copy the dll file on the java folder it works perfectly, but this solution is not acceptable.

I tried to use the java.library.path in  => doesn't work

I tried to add the <fileset id="testFileset" dir="\temp" includes="**\mylibrary.dll"/>  in the application classloader property => doesn't work

I tried to start a new OSGI bundle containing the dll file as a Liberty feature, with the manifest defining Bundle-NativeCode: /mylibrary.dll; osname=win32; osname=win64; processor=x86; processor=x86_64 => doesn't work.


Any idea?


Thanks in advance.

    For loading from the application you should set  -Djava.library.path=/myPath in the jvm.options file under the server directory (servers/<server_name>/jvm.options). Remember that should refer to a directory name, not the actual dll name.

    Hope this helps,
