Unable to Run Jena'a ARQ Command Line Utility
List Members,
I recently download the "apache-jena-2.7.2" distribution, which includes
"jena-arq-2.9.2.jar" under the "bin" directory. Unfortunately, when I run
the ARQ command line utility I receive an error message. For example, when I
execute
arq --data <some valid Turtle file> --query <some valid SPARQL query file>
the command line utility returns the following error:
Error: Could not find or load main class <Apache Jena 2.7.2 distribution
path>\ARQ
I have the following environment, PATH and CLASSPATH variables set, and I
restarted my OS.
Environment
----------------
JENAROOT = "<Apache Jena 2.7.2 distribution path>"
Path
------
.other semicolon-delimited path entries., followed by
<Apache Jena 2.7.2 distribution path>\bat; <Apache Jena 2.7.2 distribution
path>\bin
ClassPath
------------
.other semicolon-delimited path entries., followed by
<Apache Jena 2.7.2 distribution path>\bat; <Apache Jena 2.7.2 distribution
path>\bin
Your feedback is appreciated.
Regards,
Anthony

Rob,
Thanks for the replies. Yes, "cd %JENAROOT% returns the install path.

I didn't think so, but the documentation is ambiguous.

No need in Windows 7. The "PATHEXT" environment variable accounts for a number of common extensions including ".bat", and I suspect most "recent" Windows versions do as well.
Problem solved, and here is why...
For the Windows 7 "PATH" environment variable (not sure on other Windows versions):
1. Do not append this path: "...;%JENAROOT%\bat". For some strange reason, Windows 7 does not recognize user environment variables within system environment variables.
2. So, I replace it with the fully spelled "%JENAROOT%" path as follows. "...; C:\apache-jena-2.7.2\bat". This still does not work. Windows 7 does not allow whitespace characters after the semicolon delimiter. Instead, appending to the PATH variable's value as follows does work:
"...;C:\apache-jena-2.7.2\bat"
3. Given the solution in "2" resolved my earlier problem, I revised the "PATH" variable by replacing the path spelled in "2" with my original apache-jena-2.7.2 path, namely
"...;C:\(placeholder)\Documents\_MyStuff\Semantics\ARQ\ARQ 2.9.2\apache-jena-2.7.2\bat"
This also worked. Of course this makes sense, since Windows allows files names with whitespace characters, and not just Windows 7. Windows 7 install includes a "Program Files (x86)" directory name, and it does not complain when its PATH system environment variable's value contains this directory name.
Regards,
Anthony

The --version is a command line option supported by all the command line scripts (as far as I know) which just prints the version of Jena used by the tool. Essentially running this is just a smoke test to ensure your environment is appropriately set up.
If this works then you can run the commands properly and actually use them, running with --help should show you the usage for a given tool.cd

So I'm not sure what the issue is here, if you can't do a cd %JENAROOT% then JENAROOT is incorrect in some way

There should be no need to change the CLASSPATH and it isn't used by the batch scripts anyway

Are you running the batch files by their full name i.e. type 'arq.bat'
rather than just 'arq'?
While the Linux versions don't have/need file extensions for you to be able to run them the Windows batch scripts typically require the extension to be stated in order to run the commands (though this may vary depending on the version of Windows)

I accounted for the missing assignment operator and for the incorrect
version number when I assigned a value to the JENAROOT environment variable.
My question was more to the full path needed as its value.
Which one? (Understanding "\path\to\" is a placeholder)
set JENAROOT=\path\to\apache-jena-2.7.2
or
set JENAROOT=\path\to\apache-jena-2.7.2\bat\sparql.bat --version
If it is the latter, then why not set it to ...\bat\arq.bat? Also, what is
the purpose of "--version"?

I received the following error message.
"The filename, directory name, or volume label syntax is incorrect."

incorrectly...
I checked multiple times on the path value. In fact I did not type it in; I
copied it from Window Explorer's address line to ensure I had the accurate
path spelling.

As you suggest, I altered the apache-jena-2.7.2 install path such that it
contains no whitespace characters. Accordingly, I set the JENAROOT
environment variable as follows:
set JENAROOT= C:\apache-jena-2.7.2
Additionally, I appended the following path spellings to the PATH and
CLASSPATH environmental variables.
For PATH, I appended "%JENAROOT%\bat".
For CLASSPATH, I appended "%JENAROOT\bin".
When I execute the arq.bat command, I received the following error message:
"'arq' is not recognized as an internal or external command, operable
program or batch file."
Any thoughts?
Thanks.

This error means that your JENAROOT is incorrect in some way, I hit the same
error initially and realized I had just typed the path in wrong
One easy way to diagnose whether it is set correctly is to try the following
command after you've set JENAROOT:
cd %JENAROOT%
If you get "The system cannot find the path specified" then it is set
incorrectly, if it works then JENAROOT is set to a valid path.
However if this works and you still get path errors then the question
becomes does your path contain any spaces?
When I make my path contain spaces I reliably hit this error, it looks like
the scripts don't actually handle paths containing spaces correctly.
I added an issue JENA-286 (https://issues.apache.org/jira/browse/JENA-286)
for this bug and we will make sure this is fixed for the next release.
Apologies for the inconvenience caused, in the meantime the workaround is
either to manually modify the scripts you need as shown in that bug report
or to move your location to a path without spaces in it
Hope this helps,

Let's start with the distribution I downloaded. Here are the links I followed.
On the web page located at http://jena.apache.org/download/index.html, I clicked the http://www.apache.org/dist/jena/ link. This brought me to the "Apache Jena Releases" web page. On that page I selected the "binaries/" hyperlink, which brought me to the "Index of /dist/jena/binaries" (http://www.apache.org/dist/jena/binaries/) web page.
>From that web page I downloaded the "apache-jena-2.7.2.zip" file, last modified on 02 Jul 2012.
Is this the latest, stable release?
If so, the distribution contains the "README" file attached in this response. Since all the text runs together when opening it in NotePad, I instead opened it in WordPad for better readability. An excerpt from that file follows.
<excerpt>
Installing Jena
---------------
To use Jena in your application, ensure all the .jar files in the lib/
directory are on the classpath or available to your web application. Jena
is built and test with these .jar files.
Scripts
-------
The directories bat/ and bin/ provide script wrappers to run Jena command
line tools. The scripts can be copied to a convenient place on the
command path.
To use the Jena tools from the command line you need to set the JENAROOT
environment variable to point to the location where you have
unzipped the Jena distribution:
Windows:
set JENAROOT \path\to\apache-jena-2.7.1
bat\sparql.bat --version
Linux
export JENAROOT=/path/to/apache-jena-2.7.1
bin/sparql --version
</excerpt>
How precisely do you interpret setting up the JENAROOT environment variable in Window. What is stated in the README file is inconsistent with instructions provided at http://jena.apache.org/documentation/tools/:
<quote>
How to set up the CLASSPATH and run Jena command line tools
On Linux / Mac
export JENAROOT=the directory you downloaded Jena to
export PATH=$PATH:$JENAROOT/bin
On Windows
SET JENAROOT=the directory you downloaded Jena to
SET PATH=%PATH%;%JENAROOT%\bat
</quote>
Bottom line: I still receive the same error message
"Error: Could not find or load main class (...)\Documents\_MyStuff\Semantics\ARQ\ARQ"
The path presented in this error message makes no sense.
On my system the apache-jena-2.7.2 distribution install is "(...)\Documents\_MyStuff\Semantics\ARQ\ARQ 2.9.2\apache-jena-2.7.2".
I set the JENAROOT environment variable to "(...)\Documents\_MyStuff\Semantics\ARQ\ARQ 2.9.2\apache-jena-2.7.2C:\Users\Anthony Petosa\Documents\_MyStuff\Semantics\ARQ\ARQ 2.9.2\apache-jena-2.7.2".
I appended the following path to the PATH variable: "%JENAROOT%\bat".
Any thoughts?
Thanks.

Exactly what is this set to?
[[

path>\ARQ
]]
The ARQ part is wrong. There should be no capitalized ARQ - that looks more like an old (when ARQ was distributed separately) path.

Not needed - the classpath is set by the scripts - have a look at arq.bat:
You will see:
[[
set JENA_CP="%JENAROOT%\lib\*;"
]]
and
[[
java %JVM_ARGS% %LOGGING% -cp %JENA_CP% arq.arq %* ]]
You can call the java command directly.

jena.sourceforge.net is out-of-date.
Please use the jena.apache.org site.
If you go to :
http://jena.sourceforge.net/ARQ/Tutorial/
http://jena.sourceforge.net/ARQ/
you get redirected to the Apache Jena site.
The set up for apache-jena is different. See it's README.

No problem, and I appreciate your responses.
In addition to setting the environment, class and classpath variables:
Environment
----------------
JENAROOT = “<Apache Jena 2.7.2 distribution path>”
Path
------
…other semicolon-delimited path entries…, followed by
<Apache Jena 2.7.2 distribution path>\bat; <Apache Jena 2.7.2 distribution path>\bin
ClassPath
------------
…other semicolon-delimited path entries…, followed by
<Apache Jena 2.7.2 distribution path>\bat; <Apache Jena 2.7.2 distribution path>\bin
I also include additional classpath values as prescribed here: http://jena.sourceforge.net/ARQ/Tutorial/query1.html (under the section "Using the Java command line applications directly". Naturally, I added values commensurate with the aforementioned Jena release and rebooted by system for good measure.
I continue to receive the same error message:

Sorry, I wasn't clear. I meant, what happens if you set JENAROOT and use the absolute path to the executable (so as to confirm that the problem isn't with the value of PATH). But since you're getting a Java error and not a shell error, I guess ARQ is running, at least. I was just trying to decrease the number of things that could be the problem. //JT

Sorry, I wasn't clear. I meant, what happens if you set JENAROOT and
use the absolute path to the executable (so as to confirm that the

I assigned the JENAROOT variable an absolute path. I simply used "<Apache Jena 2.7.2 distribution path>\bat" in the post as a shortcut for the actual path.

Will ARQ run if you an absolute path and set just the JENAROOT variable? For instance, I can do the following:
$ JENAROOT=/usr/local/lib/apache-jena-2.7.2/
/usr/local/lib/apache-jena-2.7.2/bin/arq
No query string or query file
(I'm not a Jena developer, but a satisfied user who makes lots of use of the command line utilities and recently switched to 2.7.2.)
