Question

I am trying to connect kvm through java using the code present at

https://libvirt.org/java.html

When I try to connect i receive the below error

2016-04-23 21:18:17.960 ERROR 6359 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Handler processing failed; nested exception is java.lang.UnsatisfiedLinkError: Unable to load library 'virt': libvirt.so: cannot open shared object file: No such file or directory] with root cause

I have libvirt installed on ubuntu

 libvirtd --version
libvirtd (libvirt) 1.2.2

And my build.gradle is

dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.libvirt:libvirt:0.5.1')
    compile('net.java.dev.jna:jna:3.3.0')
    testCompile('org.springframework.boot:spring-boot-starter-test') 
}

Has anyone faced similar issue.

Answer 1

since you are on linux this exception is thrown when your application attempts to load a native library like .so .in this case JVM is looking in both the PATH environment variable and the java.library.path system property. .to fix this exception you need to set path for that library u are trying to load. just like you set path for java.
