Dear users;
Now, I try to learn log4j to see the log file in order to find what happened in
the Fuseki server.
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

It has already exited by this point - control-C is going to the command line.

There is another copy running already. Find it and kill it.
Only one process can manage a port at a time.
