I learned that I need to modify the log4j.properties file.
======
log4j.rootLogger=INFO, stdlog
## log4j.rootLogger=INFO, FusekiFileLog
log4j.appender.stdlog=org.apache.log4j.ConsoleAppender
log4j.appender.stdlog.target=System.err
log4j.appender.stdlog.layout=org.apache.log4j.PatternLayout
log4j.appender.stdlog.layout.ConversionPattern=%d{HH:mm:ss} %-5p %-20c{1} ::
%m%n
## # Example for file logging.
log4j.appender.FusekiFileLog=org.apache.log4j.DailyRollingFileAppender
log4j.appender.FusekiFileLog.DatePattern='.'yyyy-MM-dd
log4j.appender.FusekiFileLog.File=fuseki-log
log4j.appender.FusekiFileLog.layout=org.apache.log4j.PatternLayout
log4j.appender.FusekiFileLog.layout.ConversionPattern=%d{HH:mm:ss} %-5p
%-20c{1} :: %m%n
==========
I uncommented the line in Red above. I guess that all log files would be related
to Apache server: So, I ran the Apache server -->
http://50.63.174.75/ . It seems to work. I am not sure it is a right approach
to do it though. Do I need to run log4j.properties using log4j.jar command?
Then, I have stuck, since I don't know where I can see the actual log files.
I am pretty familiar with Tomcat server. Normally, the Tomcat server has a folder called
"logs". But, I am not familiar with log4j in Fuseki.
I know that it is not right place to ask the log4j questions. : (
Sorry for that.
Best,
Soonho

Dear Andy;
I successfully kill the existing application. Then, I restarted it using the
following command:
==========
[root@ip-50-63-174-75 jena]# java -Xmx1200M -jar fuseki-server.jar --update
--mem /ds
13:24:35 INFO Server :: Dataset: in-memory
13:24:36 INFO Server :: Dataset path = /ds
13:24:36 INFO Server :: Fuseki 0.2.5 2012-10-20T17:03:29+0100
13:24:36 INFO Server :: Started 2012/11/01 13:24:36 GMT-07:00 on
port 3030
===========
Then, I try to open the URL --> http://50.63.174.75:3030/
I didn't get any error message,, it keep retrieving.
that is the fuseki log file (using log4j you can send it to a file)
I would like to see any error message from this. But, I can not figure out how
I can see it.
I saw a file including "log4j". But, I don't know how to use it.
Could you kindly explain more on how to generate/see the log file?
Thanks so much! I am desperately looking for your help....
Best,
Soonho

Dear Rob;
Thanks so much for your quick answer.
The easiest way to set up a TDB dataset is actually to start up
Fuseki with a path to an empty directory and using the --update
option to enable updates
I found some document to start up Fuseki with empoty dataset from
http://jena.apache.org/documentation/serving_data/index.html
========
Fuseki Server starting with an empty dataset
fuseki-server --update --mem /ds
runs the server on port 3030 with an in-memory dataset. It can be accessed
via the appropriate protocol at the following URLs:
*SPARQL query: http://localhost:3030/ds/query
*SPARQL update: http://localhost:3030/ds/update
*SPARQL HTTP update: http://localhost:3030/ds/data ========
So I tried to run the server again using the above command.
=============
[root@ip-50-63-174-75 jena]# java -Xmx1200M -jar fuseki-server.jar --update
--mem /ds
11:53:55 INFO Server :: Dataset: in-memory

11:53:56 ERROR Server :: SPARQLServer: Failed to start server:
Address already in use
[root@ip-50-63-174-75 jena]# ^C
It has already exited by this point - control-C is going to the command line.
===============
I got the error message saying " Failed to start server: Address already in
use".
I tried shut it down using "control+c", but it seems not to work.
Do you have any idea of how to fix this problem?
Thanks so much for your answer.
There is another copy running already. Find it and kill it.
Only one process can manage a port at a time.

TDB is a native RDF database not a flat file format so you cannot simply rename
an existing RDF file to create a TDB dataset.
Please see the documentation for TDB
(http://jena.apache.org/documentation/tdb/) to learn how to create a TDB
dataset.
The dataset location in your configuration file should be a path to
directory where your TDB database has been created (or where it should
be created). The easiest way to set up a TDB dataset is actually to
start up Fuseki with a path to an empty directory and using the
--update option to enable updates. Then go to the Control Panel in
the Fuseki web interface and use the Upload File functionality to
import the file into your dataset. This will create a bunch of files
in your directory, once created you can then take a copy of the
directory (when Fuseki is not
running) in order to back it up or move it around as desired.
Hope this helps,
Rob

Dear Andy;
Thanks for your answers and pointing the mailing list archives as well.
What's "ghi.tdb"?
My dataset was stored in the flat file -->
http://data.ifpri.org/lod/ghi.rdf
I have read that Fuseki uses the TDB. So, I created a TDB (ghi.tdb)
file from the ghi.rdf file using the TopBraid Composer and put it
into under the "dataDir" directory.
I am using Jena to retrieve the data from ghi.rdf, but I am a kind of
new on the TDB.
What kind of files should I have to put under "dataDir" directory?
Is the .tdb file not the right format?
It's not clear what you are doing. What operation did you perform?
Visit a URL? Which?
That's a good question. What I would like to do is that I would like
to see the Fuseki main screen, using my dataset "ghi.tdb". That's why
I typed http://50.63.174.75:3030/.
What was the browser action?
What did you get?
I ran the Fuseki server again. The browser just keeps retrieving......
I didn't get any error message.
Did you copy the jar elsewhere or are you running in the unpacked
installation directory.
I am running in the unpacked installation directory.
I am so sorry for asking many questions. However, this email list is
the only channel which I will get answers.
Thanks so much for your support in advance.
Best,
Soonho

Something was wrong since I didn't get the proper response from the
server.
What was the browser action?
What did you get?
http://...:3030/ is a simple plain HTML page from the pages/ directory.
Did you copy the jar elsewhere or are you running in the unpacked
installation directory.
If you copy the jar, and you want the web pages, you need to
Or use --pages on the command line to name another directory.
Is there any log file to check what was wrong?
that is the fuseki log file (using log4j you can send it to a file)
If you find something is wrong, please let me know... It would be a
great help to a newbie like me.
Best,
Soonho
