Error: libjvm.so: cannot open shared object file: No such file or directory

[jonnydungeons]

This happens on Heroku when load up the node-jdbc plugin which depends on this plugin. Full error is this:

Error: libjvm.so: cannot open shared object file: No such file or directory

@J0NNYZER0 How can you solve this problem?

If someone is coming here now, Please try the approach below:

Steps:

1. Find your R location. It will be stored in rsession-ld-library-path in rserver.conf file. Or just by doing which R. The location usually is /usr/lib64/R/lib or /usr/lib64/microsoft-r/3.3/lib64/R/lib
2. Find the libjvm.so file which is usually in the usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server path depending on which jre you're using. Check in $JAVA_HOME environment.
3. Create a symlink using ln -s
sudo ln -s /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/amd64/server/libjvm.so /usr/lib64/microsoft-r/3.3/lib64/R/lib/libjvm.so
4. Restart R server

@J0NNYZER0 What did you do? How did you solve it?

I figured it out.

1. Find where libjvm.so is located. /app/.jdk/jre/lib/amd64/server in my case.
2. Add it to LD_LIBRARY_PATH env var. I'm adding this in starting script.

I'm seeing this problem as well. Locally on OSX, everything is working great. When I move to ubuntu, I'm seeing the 'libjvm.so: cannot open shared object file' error. I've tried setting the follow env variables as well:

export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
export LD_LIBRARY_PATH=/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/server

But no luck. All suggestions appreciated.

This is not a Heroku project.

node Java is not tested with openjdk.
