The README contains wrong Java namespace

[pkiraly]

Dear developers,

the README contains an example, how to run the software, i.e.:

mvn exec:java -Dexec.classpathScope=test -Dexec.mainClass="fr.univLille.cristal.shex.commandLine.Validate" -Dexec.args="-s ../../shexTest/schemas/1dotSemi.shex -d file:///home/jdusart/Documents/Shex/workspace/shexTest/validation/Is1_Ip1_Io1.ttl -l http://a.example/S1 -f http://a.example/s1 -a recursive"

According to this, the Java class is fr.univLille.cristal.shex.commandLine.Validate, however in your basic namespace is fr.inria.lille.shexjava.

I have another question: Do you have examples for running the software from the command line without Maven, such as:

java -jar shexjava-core-1.0.jar validate [parameters]

?

I tried this way:

java -cp target/shexjava-core-1.0.jar:[additional jars] \ 
  fr.inria.lille.shexjava.commandLine.Validate \
  -s ../../shexTest/schemas/1dotSemi.shex \
  -d file:////[path to]/validation/Is1_Ip1_Io1.ttl \
  -l http://a.example/S1 -f http://a.example/s1 -a recursive

and what I get:

Error while reading the data file.
Caused by: 
Did not recognise RDF format object Turtle (mimeTypes=text/turtle, application/x-turtle; ext=ttl)
Was unable to the parse data. Aborting.

The namespace changed recently. fr.univLille.cristal.shex is now fr.inria.lille.shexjava.

I don't have example without maven, but it should be really similar. I think there is a problem with the url of the file. You have written file:////[path to]/validation/Is1_Ip1_Io1.ttl and I think there is too many / at the beginning. For the url it is file:// then followed by the absolute path to your file. Can you try that and if it doesn't work can you give me the full URL that you are using?

[pkiraly]

Thanks for the response!

My suggestion is that you should update the README file accordingly.

I got the same response even if I put three '/'-s. The file points to the [git]/shexTest/validation/Is1_Ip1_Io1.ttl file (where [git] is the absolute path of the parent directory of the cloned shexTest project). If I remove the file:// protocol notation I get a different error mesage:

Error while reading the data file.
Caused by: 
no protocol: [git]/shexTest/validation/Is1_Ip1_Io1.ttl
Was unable to the parse data. Aborting.

I have updated the readme.

Can you try running the following command and give me the output?

mvn exec:java -Dexec.classpathScope=test -Dexec.mainClass="fr.inria.lille.shexjava.commandLine.Validate" -Dexec.args="-s ../../shexTest/schemas/1dotSemi.shex -d https://raw.githubusercontent.com/shexSpec/shexTest/master/validation/Is1_Ip1_Io1.ttl -l http://a.example/S1 -f http://a.example/s1 -a recursive"

[pkiraly]

Sure, this is what I get:

Validating graph https://raw.githubusercontent.com/shexSpec/shexTest/master/validation/Is1_Ip1_Io1.ttl against schema ../../shexTest/schemas/1dotSemi.shex.
Typing constructed.
http://a.example/s1 SATISFIES IRI:http://a.example/S1

And also, if I use file:///... notation in this command I received the same output. I received the error when I try to use it without maven, with pure Java. Maybe this part is handled by a Java library which I did not include into the classpath.

[jdusart]

So I guess the next step is to try using the same classpath as maven. After some search, you can print it using the command:

mvn dependency:build-classpath -Dmdep.includeScope=runtime 

Otherwise, the parsing of the data is done by the following code:

import org.eclipse.rdf4j.rio.RDFFormat;
import org.eclipse.rdf4j.rio.Rio;

...

java.net.URL documentUrl = new URL(dataFileName);
InputStream inputStream = documentUrl.openStream();
dataModel  = Rio.parse(inputStream, documentUrl.toString(), RDFFormat.TURTLE);

[jdusart]

So I managed to make it works using the following command lines:

mvn dependency:build-classpath -Dmdep.includeScope=runtime -Dmdep.outputFile=cp.txt
SHEXCP="target/shexjava-core-1.1.jar:"`cat cp.txt`
java -cp $SHEXCP fr.inria.lille.shexjava.commandLine.Validate -s ../../shexTest/schemas/1dotSemi.shex -d https://raw.githubusercontent.com/shexSpec/shexTest/master/validation/Is1_Ip1_Io1.ttl   -l http://a.example/S1 -f http://a.example/s1 -a recursive

This produces the following output:

log4j:WARN No appenders could be found for logger (org.eclipse.rdf4j.rio.RDFParserRegistry).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Do you manage to reproduces it?

[pkiraly]

It works this way. Thanks a lot!

[jdusart]

You are welcome. I am closing this issue if you don't have anything to add?

[pkiraly]

No, I don't have. You can close it.
