Depends on how you are running Fuseki? You have set, env, declare and
export.
dick@Dick-M3800:~$ name=a
dick@Dick-M3800:~$ echo ${name}
a
dick@Dick-M3800:~$ declare name=b
dick@Dick-M3800:~$ echo ${name}
b
dick@Dick-M3800:~$ export name=c
dick@Dick-M3800:~$ echo ${name}
c
With export the variable is available in sub shells.

Re: Unsupported major
Dear Dick, You are right. I have Java version 1.6.0_37 and the exception says: "minor version 52.0" Am I right, that Fuseki 1.3 requires Java 8 (that I used previously)? I am afraid that the administrators / or the system itself downgraded the Java version to Java 6, which is the pre set or automatic version. Now I switched to Java 8, and now it works. How can avoid this problem next time? Fuseki takes into consideration the JAVA_HOME system variable? If yes, how and where should I set it? In a starting script of Fuseki?

Dear List Members, I wanted to start Fuseki 1.3.0 for test purposes, but I got an exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/jena/fuseki/FusekiCmd : Unsupported major.
