Apache Jena installation issues with JENAROOT (on Mac)
Hi all,
I'm having an issue getting Jena up and running on my Mac. I think I have
everything installed right, but I must be missing something. Details below
(and on StackOverflow
<https://stackoverflow.com/questions/49991720/apache-jena-installation-issues-with-jenaroot-on-mac>
).
Any ideas appreciated.
Thanks!
$ sparql --version
Jena: VERSION: 3.7.0 Jena: BUILD_DATE: 2018-04-05T11:04:59+0000 ARQ:
VERSION: 3.7.0 ARQ: BUILD_DATE: 2018-04-05T11:04:59+0000 RIOT: VERSION:
3.7.0 RIOT: BUILD_DATE: 2018-04-05T11:04:59+0000
Here are my current environmental variable settings:
$ echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home
$JENA_HOME
/Users/username/Documents/jena/apachejena370
echo $JENAROOT
/Users/username/Documents/jena/apachejena370
$ echo $CLASSPATH
/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/bin:/Users/username/Documents/jena/apachejena370/lib/*
When I run the code:
$ sudo java Tutorial01
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/jena/rdf/model/ModelFactory
at Tutorial01.main(Tutorial01.java:34)
Caused by: java.lang.ClassNotFoundException:

I've also somehow broken something because javac is no longer working: $
sudo javac Tutorial01.java

You should be adding $JENA_HOME/lib/\* to the CLASSPATH rather than the bin/ subdirectory

This worked!
I ran a slightly tweaked version of Jean-Marcs script:
unset JARS
for f in $JENA_HOME/lib/*.jar
do
JARS=$JARS:$f
export JARS
done
I then added $JARS to my CLASSPATH and everything works great!
Thanks all!

Re: Apache Jena installation issues with JENAROOT (on Mac)

Dear Cumulative,
here is the script I use in Linux to build the classpath :
unset JARS
for f in lib/*.jar
do
JARS=$JARS:$f
done
which gives:
echo $JARS
:lib/collection-0.7.jar:lib/commons-cli-1.4.jar:lib/commons-codec-1.11.jar:lib/commons-csv-1.5.jar:lib/commons-io-2.6.jar:lib/commons-lang3-3.4.jar:lib/httpclient-4.5.3.jar:lib/httpclient-cache-4.5.3.jar:lib/httpcore-4.4.6.jar:lib/jackson-annotations-2.9.0.jar:lib/jackson-core-2.9.0.jar:lib/jackson-databind-2.9.0.jar:lib/jcl-over-slf4j-1.7.25.jar:lib/jena-arq-3.6.0.jar:lib/jena-base-3.6.0.jar:lib/jena-cmds-3.6.0.jar:lib/jena-core-3.6.0.jar:lib/jena-dboe-base-3.6.0.jar:lib/jena-dboe-index-3.6.0.jar:lib/jena-dboe-transaction-3.6.0.jar:lib/jena-dboe-trans-data-3.6.0.jar:lib/jena-iri-3.6.0.jar:lib/jena-rdfconnection-3.6.0.jar:lib/jena-shaded-guava-3.6.0.jar:lib/jena-tdb2-3.6.0.jar:lib/jena-tdb-3.6.0.jar:lib/jsonld-java-0.11.1.jar:lib/libthrift-0.10.0.jar:lib/log4j-1.2.17.jar:lib/slf4j-api-1.7.25.jar:lib/slf4j-log4j12-1.7.25.jar:lib/xercesImpl-2.11.0.jar:lib/xml-apis-1.4.01.jar
Then I can compile or run :
java -cp $JARS riotcmd.riot --help
riot [--time] [--check|--noCheck] [--sink] [--base=IRI] [--out=FORMAT]
[--compress] file ...
Parser control
--sink Parse but throw away output
--syntax=NAME Set syntax (otherwise syntax guessed from file
extension)
--base=URI Set the base URI (does not apply to N-triples
and N-Quads)
--check Addition checking of RDF terms
--strict Run with in strict mode
--validate Same as --sink --check --strict
--rdfs=file Apply some RDFS inference using the vocabulary
in the file
--nocheck Turn off checking of RDF terms
--stop Stop parsing on encountering a bad RDF term
--stop-warnings Stop parsing on encountering a warning
... etc ....
Or you can do this to have the absolute files in CLASSPATH:
unset JARS
for f in $JENA_HOME/lib/*.jar
do
JARS=$JARS:$f
done

Re: Apache Jena installation issues with JENAROOT (on Mac)
Posted by Cumulative Knowledge <kn...@gmail.com>.
Hi Lorenz,
Thank you for the support - I'm still getting oriented.
Based on Andys feedback I added the environmental variable for classpath
with '...\lib\*' to include all the jars in the directory. I've also tried
running it like you mentioned:
javac -cp <THE_CLASSPATH_TO_JENA_LIBS_HERE> Tutorial01.java
I still get the same errors. Maybe I'm misunderstanding the directories,
file paths, and files I need to configure for Jena on a Mac. This could be
a lower level of information than what most first time Jena users need.
Currently all the paths point to the bin and lib directory in the main
folder. The jar files in the lib directory all have names which include
version numbers. Nothing is pointed to the bat directory. I'm running the
file from terminal in the same directory as the file.
Does anything seem weird with this set up? Do I need to rename files in the
lib directory? Should I point to the bat directory or execute those files?
Thank you for your patience!
Louis
More info below.
In Mac I have set JENA_HOME and JENAROOT set to the main directory for
jena:
/Users/username/Documents/jena/apachejena370
I don't know if it makes a difference, but I renamed the directory from:
/Users/username/Documents/jena/apache-jena-3.7.0
When adding JENA_HOME to the PATH I included did so as:
export PATH=$PATH:$JENA_HOME/bin
When adding the classpath I did so with:
export CLASSPATH=$CLASSPATH:$JENA_HOME/bin/\*
