Question

How do i set it in the Linux environment?

I keep getting the below error.
I am assuming its because i have to set the -Djava path . in eclipse i set in the arguments in the run configuration.

java.lang.UnsatisfiedLinkError: /opt/apache-tomcat-8.0.33/temp/librocksdbjni1678787310187961141..so: libgflags.so.2: cannot open shared object file: No such file or directory

Answer 1

You need to set the JVM parameter in [path to tomcat]/bin/catalina.sh, in the variable CATALINA_OPTS or JAVA_OPTS.

The value should be a valid Linux path (or paths) containing your libraries.

You can refer to this question: add jvm options in tomcat
