System.out.println logged to ?

I am using Oracle 9ias 9.0.3 java edition.
I have deployed a war file successfully using EM.
i HAVE System.out.println statements in my servlets. I was unable to find any documents which tell me where these statements will be logged?
Any one help me.

Go to server properties page of OEM and edit OC4J options under Command Line Options. You will have to specify the OC4J option -out filename to capture the System.out messages. You can also specify the option -err filename to capture all the errors.

Java Beans System.out.println Log file

Helllo,
I have Forms 11.1.2 installed on linux. I developed a java bean and put some System.out.println() statements. The bean itself is working but where do i look for the debug statement logs that i am generating via System.out.println() statements.
Please let me know if you need more information, I will post asap.
thanks in advance,
Prasad.

Prabodh,
thanks, added the following line to the implementation class in java bean:
private final static Logger logger = Logger.getLogger(MyBean.class.getName());
and then in the init() method, i put
logger.info("Prasad .... in init);
Does this automatically goes into weblogic managed server WLS_FORMS (in my case) standard out?
Or do i need to do anything else, i know weblogic comes up with its own diagnostic logging and is famous for supressing other loggers.... just want to run this by you as well.
thanks,
Prasad,

Print System.out.println messages into logs of Weblogic Application Server

Hi,
I use Weblogic Application Server 10.3.6 on Windows 7. The Enterprise Application (J2EE) is deployed into the 'AdminServer' of Weblogic. For debugging purpose, I have added a few System.out.println statements.
I am unable to see the print messages on any of log files available in path 'user_projects > domains > base_domain > servers > AdminServer > logs'. However, I can see them on the 'command' prompt which was used to start the server. How can I get them into one of the log files? What am I missing?
I tried reading other threads on the forum and as per them 'System.out.println' gets logged onto *.out logs which I am unable to find. Only base_domain.log, AdminServer.log, access.log are available in the location.
More Specifics:
Configuration on WLS console 'Home > Servers > AdminServer > Logging'
Log file name: logs/AdminServer.log
Min. Severity to log: Notice (tried with Debug as well)
Advanced Options:
Logging Implementation: JDK
Redirect stdout logging enabled: False (tried both options)
Log file Severity Level: Notice (tried with Debug as well)
Standard Out Severity Level: Notice (tried with Debug as well)
Thanks

Paul,
I just found this on google:
'Generally, developers put a lot of System.out.println statements in their code to perform application debugging. Normally, all standard outputs and error outputs are routed to the console where the OC4J server is started. If you want to capture the standard output and error outputs to files for logging/debugging purposes, then you can use the -out and -err options while starting up the Oc4J server to specify which files to use.'.

System.out.println in which log file

          We are using weblogic 51 server.
          We have System.out.println's in the servlets but don't see
          it in any log file. Which log file would/should
          it go to.


If you are running a shell script (not as as service) you will see it in
          that shell window, if you run it without a console window (service), you
          usually see nothing.
          If you are using a third party tool to run the server as a service (e.g.
          ServiceMill for Win2k/NT) you usually can set files where you would like
          your output to be redirected.
          If you run the server as a service and don't have this option you can do
          it yourself by setting System.setErr / System.setOut, e.g. in a
          startup-class

Where does the logging happens for System.out.println

Hello:
I'm usingNetWeaver 2004sJava SP9 evaluation version. Added some System.out.println to the ejbs. Would like to know where to look for the logging details in this case.
Thanks for your help,
Ravi

Hi,
By default, if the setting has been done, then it appears in defaultTrace as mentioned. For configuration of it, refer to this link.

System.out.println and log file

          I am developing jsp on BEA Weblogic 613 on Solaris.
          What if i run the following statement
          System.out.println("Hello world");
          I understand that Hello World will be printed to the server console. I do not
          have access to this console. Is there any log file or temporary log file it gets
          sent to? If not, is there anyway to redirect output from the console to someplace
          else?
          Thanks!


You can redirect console output for stdout on Solaris like so:
          java weblogic.Server > consoleoutput.txt
          then in a terminal window you can see whats going on with
          tail -f consoleoutput.txt

Where to see the System.out.println statements on soa server.

Hi,
I have generated some proxy classes in my jdeveloper. And I have deployed that project to the admin server on my soa_domain.
Now my java files have some System.out.println statements. I want to see those values.
Can anyone please let me know where I can see those statements on server.
What s the file name where i can see.
do i have to enable some debigging on the server. if yes then for what level i need to enable the log at what level.
Thanks
Anoop

Hi,
System.out.println is not really a good way to debug in weblogic... If you didn't configure where the stdout will go those messages can end up going nowhere...
I suggest you use one of these...
This will go to the soa*diagnostic logs... for example DOMAIN_HOME/servers/soa_server1/soa_server1-diagnostic.log...
import java.util.logging.Level;
import java.util.logging.Logger;
import oracle.fabric.logging.LogFormatter;
    private static final Logger soa_logger = Logger.getLogger("oracle.soa.Logger");
    static {
        LogFormatter.configFormatter(soa_logger);
        soa_logger.log(Level.INFO, message);
        soa_logger.log(Level.INFO, message, t);or
This will go to the server logs... for example DOMAIN_HOME/servers/soa_server1/soa_server1.log...
import weblogic.logging.NonCatalogLogger;
    private static NonCatalogLogger weblogic_logger = new NonCatalogLogger("SomeMeaningfulNameHere");
        weblogic_logger.notice(message);
        weblogic_logger.notice(message, t);Usually info and notice will go to the logs by default, you can try with higher levels (error,warning) as well or you can tweek the server debug level to use lower levels...
Cheers,
Vlad

System.out.println not showing up in the console

Hi,
I've some System.out.println statements in a static block in a Stateless
Session Bean. I could not see these outputs in the Weblogic console. I'm
using Weblogic 5.1 Any one faced this problem before? any help is
appreciated.
Thanks & Regards,

Take a look in the weblogic log files they might be redirecting std out.

Hi Ryan,
Thanks for your reply and sorry for the long silence. I was on vocation.
Thre problem still remains.I'm very sure that the EJB
is deployed by WebLogic as I'm able to call some methods.
and I'm also calling EJB methods from Servlet. But my
System.out.println statments work fine in the Servlet and
not inside EJB (or anyother classes used by EJB).
Any one has faced similar problems? BTW am using WebLogic 5.1
Thanks in advance,

Hello Nithi,
I find it strange that your System.out.println statements are beingexecuted from
within your servlets, but not in your stateless session bean. Are
you
positive
that your EJB is being located and deployed by WebLogic? The statementsin
your
static { } block should be executed as soon as the WebLogic class
loader
finds
the class and loads it into the JVM. I would suggest examining theconsole
and
try to determine if your EJB is in fact being deployed. Are you invokingmethods
on the EJB inside of your servlets? Are you using any logging frameworkfrom within
the EJBs which would redirect output to a file?
Best regards,
Ryan LeCompte

Hi Ryan,
Thanks for your reply. The setting in the weblogic.properties is

weblogic.system.enableConsole=true
So, that tells me that I should see all the System.out.printlns right?
(Pleasecorrect me if I'm wrong). I can see all the System.out.println
from
my
servletand not from the Session Bean (even if the System.out.println

Please let me know your thoughts.

Are you sure that you don't have WebLogic configured to redirect

Linux System.out.println()

I am porting some JSP's from Windows to SUSE Linux. These JSP's call functions that are embedded in JAVA classes, which in turn output error messages with System.out.println() to the console. It appears that in Linux, the bash Konsole doesn't print these errors, so they are invisible.
I suppose that if I wrote JSP's in the future, errors could be printed in the browser, but I would really like to be able to see my errors in bash or which ever shell. Any help would be appreciated.

If you ever intend to use more than one webserver, I would suggest you look towards something like JMS. Messages can be sent to the queue from which you can pick them up and deal with them as necessary in your own time, be that real-time or delayed.
If you think you will never need more than one, why not write a little log file reader? Remember though that the catalina.out file will grow and grow unless you stop Tomcat, rename the old file and restart Tomcat.

System.out.println in SAP J2EE Engine - Config Tool

Hi everybody.
I was having problems with viewing my System.out.println sentences in my NetWeaver's J2EE applications.
It's supposed that I can't see the files because I have to assing a log archive for System.out controller in SAP J2EE Engine - Config Tool.
The problem is that I can't find the place to modify the property of that controller!
I've edited the log-configuration.xml file, but when I restart the server to reload the new configuration, the files I've added to this file, disapear.
Any idea about this???
Any answer is well accpeted.
Thanks,
Alberto.

Nobody knows something about this System.out problem??
Thanks!

System.out.println in Java Studio Creator 2

Where do my debugging messages sent to System.out.println go?
In my other installations of netbeans they went to a window in the IDE but I can't find them with JSC 2.

you can use System.out.println("") to write something in output (which in web applications it is web application log file)
also in creator you can use log("") to write something in output which again is the log file.
you can view the log file by right click on server / view log file

Sustitution of System.out.println in Graphical mode

Dear Sirs:
I am changing my applications to graphical mode. I would like to know what is the command that substitutes System.out.println in graphical mode. Thanks in advance

I am not sure exactly what you mean when you say you are changing your apps to graphical mode,
I assume you will be using Swing?
If you will be using a gui in the place of a command prompt program, you may need to completely redesign your app (I'm not sure I can help you with that).
In a Java applet, and application, you can still use System.out.println. It will print to the console while your app runs. I use it pretty often for simple debugging (Although I use JBuilder and the option for the execution Log, if you are in windows and expect the size of the errors to be large an don't have something like this, you may want to run the output into a file using the IO package).
Hope this helps you,
Dan Hughes
