problems running ARQ on Command line
Hi there, I downloaded Jena 4.0 and tried to run arq in the command prompt. To test, I did
> arq --help and it gives me
Error: Could not find or load main class arq.arq
I did try EVERYTHING suggested in the documentation
I never had problems running arq on command line before.
Any suggestions will be greatly appreciated.
Thank you so much.
Regards, Neli.

Something doesn't add up here. Why is the error about 'bin' and not 'arq'?
What OS are you running this on?

If you're on Windows, you should use the .bat scripts, not the shell
scripts (.sh).
I tried with cmd now:
C:\Users\pumba\WebRoot\AtomGraph\jena\apache-jena
λ bat\arq
JENA_HOME not set

No worries. Those things happen quite often - I'm also quite often sure
I did exactly what I had to do, and once I double check after wasting
time on investigating at other possible error sources, I feel dumb.
Glad it works now, have fun!
Cheers.

Hi Lorenz -- just want to thank you for the help -- totally my fault, my settings for JENA_HOME and path variable were inconsistent. Sorry for wasting your time on something I was supposed to catch myself.

that does change everything. Next time please do not mind to mention the
operating system. Indeed, the "/bin/arq --help" as "/bin" is just for

that does change everything. Next time please do not mind to mention the
operating system. Indeed, the "/bin/arq --help" as "/bin" is just for
Linux users.
I do not have Windows, but the question is, did you follow the

No, it has always been the same -- Windows 10. As always, I give instructions to my students how to set up arq on their computers, and all but one student did not have any problems with it. One student had problems installing it on his new PC and after being unable to do so, get it to work on his old PC. I am planning to try to get it installed on my old PC that has no apache jena on it to see what happens. I am using Fuseki as a way around at this point. This is very confusing indeed.
Thank you for any idea that you may have to help me fix this.

I'm confused. Did you change your operating system since you used it
last time? As it was working before, was it MacOS or Linux and now
you're using Windows?

Re: Re: problems running ARQ on Command line

I'm confused. Did you change your operating system since you used it
last time? As it was working before, was it MacOS or Linux and now
you're using Windows?

I have jena Fuseki installed on both computers (work file) and different versions of apache-jena (I need v.3.16 for Pellet). Is there any issue with all these different versions installed simultaneously?

Re: problems running ARQ on Command line
Posted by "Zlatareva, Neli (Computer Science)" <Zl...@ccsu.edu>.
Hi Lorenz, thank you for the quick response.
bin/arq --help does not work (from ...\apache-jena-4.0.0 directory).
The error is
'bin' is not recognized as an internal or external command,
operable program or batch file.
I tried to run
arg --help from the bin directory and it gives me the same error as I was getting initially.
Error: Could not find or load main class arq.arq
Caused by: java.lang.ClassNotFoundException: arq.arq
I tried on a different computer with an older version -- this worked fine before -- but now I am getting exactly the same problem. I have jena Fuseki installed on both computers (work file) and different versions of apache-jena (I need v.3.16 for Pellet). Is there any issue with all these different versions installed simultaneously?
Any suggestions will be hugely appreciated.
Thank you.
Regards. Neli.

I cannot reproduce this:
- downloaded latest Tarball archive
- extracted archive
- changed directory
- called "bin/arq --help"
can you try to call "bin/arq --help" from the Jena base directly please?
If it works, then it's probably a classpath issue with your environment
variables
