Tomcat 7 only requires Java 6
It looks like it is being run with Java6 despite your command line
settings showing Java7.
Are you running tomcat as a service?

Hi Jena team,
Following the installation instructions from
http://jena.apache.org/documentation/serving_data/ the fuseki server
2.0.0 starts from command line and it runs as well on local port 3030.
# cd /opt/apache-jena-fuseki-2.0.0

But *fuseki.war* failed to start on Tomcat 7.0 (see error [1]). An
upgrade to Java to 1.7.0_51 didn't help, the error still occurs.
# java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
# echo $JAVA_HOME
/usr/lib/jvm/java-7-openjdk-amd64/
# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04.5 LTS
Release: 12.04
Codename: precise
It seems no permission issue for Tomcat to read the jar files, for example:
# ls -lrt
/var/lib/tomcat7/webapps/fuseki/WEB-INF/lib/jena-fuseki-core-2.0.0.jar
-rw-r--r-- 1 tomcat7 tomcat7 252125 Mär 8 09:57
/var/lib/tomcat7/webapps/fuseki/WEB-INF/lib/jena-fuseki-core-2.0.0.jar
That's not the WAR file.
Could you provide any advice how to fix this error please?
Thank you in advance,
Sorin
