using JNI libraries in ubuntu

Im am trying to use a JNI library but unable to locate where the .so files are on my ubuntu machine?

The reason I need to find it is because I suspect Im using an older version and like to replace it with a newer one.

Its more of an ubuntu question rather than jni.

Any help is appreciated.

The answer will differ depending on which library you are looking for.

You will find some in /lib

others in /usr/lib

depending on what you have installed you may also find .so's in /usr/local/lib

and possibly anywhere else in the system (see Duck's answer above for a way to find them all).

For a specific library you have installed from a package, for instance the JNI .so installed by the sun-java6-bin package you use dpkg to query for the package listing and look for where the files are you want.

dpkg -L sun-java6-bin | grep '\.so'

Which will indicate that most of this package is installed under /usr/lib/jvm/java-6-sun-*.

If you aren't sure which package your java was installed with you can search the list of installed packages with:

dpkg -l | grep java

I hope this helps.

find / -name "mylib.so" 2>/dev/null

If the filename is a symbolic link, follow the link to the actual lib.
