Hi. I have a problem with sesame soprano backend. It don’t see libjvm.so though openjdk is installed and is in /usr/lib64/jvm/java-1.6.0-openjdk-1.2_b11/jre/lib/amd64. It is necessary to work strigi/nepomuk on kde 4.2.0. Please help.

  1. Find libjvm.so (in my openSUSE 11.0 is in /usr/lib64/jvm/java-1.6.0-openjdk-1.2_b09/jre/lib/amd64/server/ )

  2. Make symbolics link:

ln -s /usr/lib64/jvm/java-1.6.0-openjdk-1.2_b09/jre/lib/amd64/server/libjvm.so /usr/lib64/libjvm.so

And soprano with sesame will be work.

It Works! Thanks.

Dzięki. :slight_smile:

Thanks, this fixed it for me too. Is there a package that is supposed to install /usr/lib/libjvm.so or is it a problem with the soprano-backend-sesame package?

Upon further investigation the library libsoprano_sesame2backend.so has a RUNPATH of /usr/lib/jvm/java/jre/lib/i386/client, so it seems it was compiled on a system without the opensuse java package. However, the opensuse java packages may also take some blame for not linking /usr/lib/jvm to the path of the currently installed jvm.

Rather than linking /usr/lib/libjvm.so I have instead linked /usr/lib/jvm/java/jre -> /etc/alternatives/jre.

Though now I have the problem as follows:-

Apparently this can be fixed by installing the Sun JDK instead of OpenJDK.

If I chmod 777 /usr/lib/jvm/java then run sopranocmd, it works, but it seems to store data there so it is not suitable for multiple users.

yea this command worked for me

ln -s /usr/lib/jvm/java-1.6.0-openjdk-1.6.0/jre/lib/i386/server/libjvm.so
