Execute Schemagen (Jena) from the command line / classpath setting - command-line

Question

I am learning the Jena API and I want to use Schemagen to create the classes that look like in the package com.hp.hpl.jena.vocabulary for my own vocabulary;
I donwloaded Jena at http://www.apache.org/dist/incubator/jena/apache-jena-2.7.0-incubating/. Once downloaded I unzipped it and leave it as it is.
C:\Users\moi\NetBeansProjects\apache-jena-2.7.0-incubating\apache-jena-2.7.0-incubating
is the folder where there is the bat folder, the bin folder, the javadoc-arq folder etc.
I tested Jena in one of my project using all the libraries in C:\Users\moi\NetBeansProjects\apache-jena-2.7.0-incubating\apache-jena-2.7.0-incubating\lib with a relative link, and it works.
To make it simple to use in the command line I moved my file "MyKnowledgeBase.rdf" in the lib folder.
I tried from the lib folder
java jena.schemagen -i "myKnowledgeBase.rdf"
and get this
Exception in thread "main" java.lang.NoClassDefFoundError: jena/schemagen
Caused by: java.lang.ClassNotFoundException: jena.schemagen
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: jena.schemagen. Program will exit.
So I tried to set the classpath :
C:\Users\moi\NetBeansProjects\apache-jena-2.7.0-incubating\apache-jena-2.7.0-incubating\lib>
set CLASSPATH=commons-codec-1.5.jar;httpclient-4.1.2.jar;httpcore-4.1.3.jar;icu4j3.4.4.jar;jena.arq-2.9.0-incubating.jar;jena.core-2.7.0-incubating.jar;jena.iri0.9.0-incubating.jar;log4j-1.2.16.jar;slf4j-api-1.6.4.jar;slf4j-log4j12-1.6.4.jar;xercesImpl-2.10.0.jar; xml-apis-1.4.01.jar;
But I have still the same error. I also tried with
java -cp commons-codec-1.5.jar;httpclient-4.1.2.jar;httpcore-4.1.3.jar;icu4j3.4.4.jar;jena.arq-2.9.0-incubating.jar;jena.core-2.7.0-incubating.jar;jena.iri0.9.0-incubating.jar;log4j-1.2.16.jar;slf4j-api-1.6.4.jar;slf4j-log4j12-1.6.4.jar;xercesImpl-2.10.0.jar; xml-apis-1.4.01.jar; jena.schemagen -i myKnowledgeBase.rdf
when I do
echo %CLASSPATH%
I get what I entered
I tried to use set CLASSPATH with the absolute path for each jar and it doesn't work too.
So now I don't know what to do.
In Jena I found the schemagen.class in the package "jena" from the jena-core-2.7.0-incubating.jar (with netbeans)
With explorer I didn't find the class file.
I already run several projects in the command line doing java -jar so java and the command line is ok
Thank you for your help
Edit :
I removed the space between the argument -classpath and %CLASSPATH% and I get something different \o/ still doesn't work but it's in progress !
"Unrecognized option" and "Could not create the java virtual machine"
Edit2 :
As I was unable to solve this I created a new project with netbeans. I created a copy of schemagen class, put it as the main class, include all the jar as libraries.
and then :
java -jar "C:\Users\moi\NetBeansProjects\MyJena\dist\MyJena.jar" -i "myKnowledgeBase.rdf" -o "C:\Users\moi\NetBeansProjects\apache-jena-2.7.0-incubating\apache-jena-2.7.0-incubating\lib" --ontology

Answer 1

In all recent releases, including Jena 2.7.0, Linux shell and Windows batch scripts are provided for all of the Jena command line tools. These scripts set the CLASSPATH appropriately. Since you seem to be using Windows, you should use bat\schemagen.bat.

Answer 2

I had the same problem.I 'm using Jena 3.10
if anyone having the same problem , the solution for this is using schemagen bat file that located in the bat folder.
I used this command line for generating the vocabulary
C:\Jena\apache-jena-3.10.0\bat\schemagen.bat -i "FileName"
