OpenJDK

["Gottfried F. Zojer" <go...@gmail.com>]

Hello to everyone,

Not exactly new to Jena/Fuseki but yesterday I tried it the first-time  on
a netbook running Ubuntu and was surprised to get a Java error from the
start. The only Java program I was using on this box was jython and it
worked for a long time.
I guess by default Ubuntu is using a not compatible JRE. Hope someone can
advise if this error was seen before

./sparql
Exception in thread "main" java.lang.UnsupportedClassVersionError:
arq/sparql : Unsupported major.minor version 51.0

And if there is any link about supported JRE/JDK s for Jena (
apache-jena-2.12.0 )


Thanks in advance for any feedback

Best regards

Gottfried

You need java 7 for Jena 2.12.0.
