Where to see the System.out.println() messages

I deploy my application in Oracle9ias . I have some System.out.println() statements in java class files.
When I run the application I need to know where I can see those println() statements.

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

Where are all the System.out.printlns sent to?

I have log4j running but when this fails to load I rely on System.out's to see what went wrong. I checked the application log for the application in application-deployments/<application-name>/home_default_island_1 directory but it doesn't record the System.out's.
Regards,
Anthony

Thanks Avi,
However the OC4J Home Page is not always the answer to every question. I don't want to sound ungrateful but OAS has way too much documentation. Granted it has alot of features and operating OAS should not be delegated to a lone developer but I can 't be sifting through documentation looking for a simple answer as "Where do System.out.printlns go to"
I mean simply put OC4J (running inside OAS) has a local log per application application-deployments/<application-name>/home_default_island_1 which I would expect to be the default location for any System.outs to be. Isn't it just logical thinking? I'm not sure exactly what opmn's relationship with OC4J is but from a developer point of view it's a different entity!?!
For now I'm still refining our development processes for an upcoming project so it looks like I'll be ditching developer testing on OAS full install to running a local OC4J standalone - too much time is wasted deploying an app for a start and there is no easy access to the remote console logs. Also the System.outs in standalone are easily visible anyway.
Please understand this is not a formal complaint or grudge but a developers desparate cry to try and get a job done.

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.'.

Where do Java Embedding "System.out.println()" go? Where is Java Console?

Assume I embed a "Java Embedding" object in a BPEL process
and write the following Java code into it:
System.out.println("Hello BPEL");
where does this text go when executed? If I remember it well there must be somewhere an AppServer console.
But where is it exactly ?
Peter

Hi Peter,
The out stream is generally redirect into files in applications servers.
OC4J : $ORACLE_HOME/opmn/logs/<your_group>~<your_home_name>~<your_group>~1.log
WebSphere : $LOG_ROOT/SystemOut.log
JBoss : $SERVER_LOG_ROOT/server.log
Hope this helps.

Want the "System.out.println()" that is within the java stored procedure works?

hello
i write a java stored procedure,and put a line as "System.out.println(...)" within the procedure,after publish it,i can test it within the sqlplus by invoke following command:
SQL>set serveroutput on;
SQL>call dbms_java.set_output(....);
but when i test it within the jdeveloper9.0.3,it can't be print,why?
thank you!

You can try this:
DBMS_OUTPUT.enable(100000);
DBMS_JAVA.set_output(100000);

Where the hell do the system.out.println s go ??

I am using 9ifs 9.0.1 in windows accessing ifsservers through jsps.
I am wondering where will the SOP 's be printed whil accessing the ifsserver through jsps 's.
I guessed it was at the apachev jserv log files. I turned the log on and also checked all the flags - info, debug, etc.
Even then i cudnt fing the SOP 's getting logged ...
Can anyone give a clue...
Thanx,
RaviSankar

Have a look at the $ORACLE_HOME/9ifs/log/Node.log file.
(If you use system.err.println, you will find them in the $ORACLE_HOME/Apache/Apache/logs/error_log.)
Hope this helps,
Bob

Where will the System.out.println write to when using OC4J -9iAS 9.0.3?

Hi:
We are using OC4J 9.0.3 that is bundled into 9iAS 9.0.3 on Windows 2000. We are starting/stopping OC4J using Enterprise Manager Web Site. Is there a way to display java logs (System.out's in the code) somewhere when we access a web application that is deployed on OC4J?
If not, can we start/stop oc4j using console in 9iAS?
When I start it like
C:\9iASHOME\j2ee\home>start java -jar oc4j.jar
even though it looks like Oc4j is started, I get an Internal Server error when I display a page. I can display the same page whenever I start oc4j from Enterprise Web Site.
Thanks!!

Tomcat Java Servlets, how to log System.out.println() messages

I have recently installed a new (x86) Mac OS Xserve, and am porting some Java application Servlets from an existing older Mac OSX server. All the servlets were working (I am connecting via port 9006). I have carefully used the old JDK 1.4 compiler, edited my server.xml (for port 9006) and web.xml files, etc. The Tomcat example servlets work fine, and all my (other) servlets work fine, with one exception, where I get the typically vague "java.io.IOException: Server returned HTTP response code: 500" message.
Trouble is, I cannot get the Java System.out.prinln statements to go to the Tomcat/logs/ log files (they are all there and updating with Tomcat HttpServlet messages), in order to properly debug.
Is there a server.xml value somewhere I can make the change?
On another minor (possibly related) point, does anyone know what the path info ='null' means in the Tomcat access log? e.g.,
StandardContext[/my_servlets]: Mapped to servlet 'myServlet' with servlet path '/myServlet' and path info 'null'
It is the only other suspicious message I get in all the logs.
One other point: my java application that fails uses threads. All the individual classes that use the threads work when run interactively, but as soon as I call them from final Serlet class that extends HttpServlet, I get a null pointer exception. Is there something unique about the Tomcat 4.1 threading that could be causing it?
I want to avoid upgrading to Tomcat 5 at this point, if I can avoid it. My applications are modest in scope, and the last time I upgraded to Tomcat 5, it took me days to get it working properly, and I lost all access to it from the Server Admin application.

I have found a solution: Via the Tomcat Admin web page I set the Context field "Swallow Output" to "true".

Lost System.out.println statements.

Hi
I have few system.out.println in my jsp which i am using in my JSP provider channel. but when I look at the portal server's /var/opt/SUNWam/debug/desktop.debug file, none are there.. I looked at the web server's access and error logs too, but it is not there also.. can somebody tell me how do it get those ?? do we have any other mechanism to put debug logs ?

By default the binary which web server runs is uxwdog which eats up System.out.println output. If you want to see the System.out.println then you need to change the product binary from the start script of the portal server instance.
- Go to <portal-install-dir>/SUNWam/servers/https-<instance-name> and open the start script
- Change the PRODUCT_BIN=uxwdog to PRODUCT_BIN=ns-httpd , save the file
- Run the script ./start to start the portal server
Note : with ns-httpd ON the server will not leave that shell, and in the same window/shell you will be able to see all your System.out.println statements. To close the server you have to kill the server process with "kill -9 pids" command
Alternate way is to use api inside your application or jsp:
<%@page import="com.sun.portal.providers.jsp.JSPProvider, com.sun.portal.providers.*, com.sun.portal.providers.containers.*, com.sun.portal.providers.context.*" %>
<% JSPProvider p=(JSPProvider)pageContext.getAttribute("JSPProvider");
ProviderContext pc = p.getProviderContext(); %>
<%-- after that you can use these lines any where in your jsp --%>
<%
pc.debugError("your error msg");
pc.debugMessage("your msg");
pc.debugWarning("your warning msg");
%>
The perticular mgs will be shwon in /var/opt/SUNWam/debug/desktop.debug file as per your "debugLevel" parameter setting in /etc/opt/SUNWps/desktop/desktopconfig.properties file. By default the debugLevel is set to error so only pc.debugError("error msg") will be shown.

System.out.println and OAS

Hello All,
I have few System.out.println statements in my J2EE application which is running on OAS. I'm not sure where it is writing. I couldn't find anything in the server.log. Really appreciate any ideas.
Thanks

I know this is a couple of months old but it's a useful tip for anyone else having the same problem.
You can't see the System.out.println statements in any logs through the administration web pages of the OAS. You have to go through the filesystem, which is annoying and in my opinion a massive error by Oracle. But never mind.
The filepath is:
%ORACLE_HOME%/opmn/logs/default_group~***~default_group~1.log
replace *** with the name of your oc4j instance

Where does System.out.println go?

Hi Everyone: I know I've seen this topic before, but I'm still having some trouble. I would like to debug my EJBs, and so I've added some System.out.println statements to them. Where does that go? I've looked at the defaultTrace.trc files in the
C:\usr\sap\P48\JC00\j2ee\cluster\server0\log
folder, and haven't found any of the text that I think I am writing. I appreciate any guidance! Ian.

Hi lan,
I was facing the same question earlier, and now I think I have figured out one possible answer. Actually, where the System.out.println goes is up to the Server Admin to config. There is a default SYSTEM.OUT log controller ( under location controller side) pre-defined to cater for all System.out.println(). All the System.out.println() output is considered as INFO type log message. However, this default SYSTEM.OUT controller is not assigned with any real log destination, thus, we cannot find the output anywhere.
If you goes to the log configurator (using Visual Admin), you can locate this SYSTEM.OUT controller , and add in a default (Anonymous) destionation for it . (you need to toggle on the advance edit mode from the top menu , then you can add modify the destination settings of a Controller).
For Anonymous destionation, the println() output will sure go to the defaultTrace.trc (better view it using Log Viewer, instead of viewing it from the log file ).
Or , you can define a separate file (e.g. c:\temp\myStd.log ) as the log destination ..
Last but not the least, you need to set the ForceSingleTraceFile setting from 'YES' to 'NO' , then you can see your "myStd.log".
To change the ForceSingleTraceFile , go to Visual Admin, J2EE server --> Kernel --> LogManager.
Hope you find the above useful.

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

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?

So, that tells me that I should see all the System.out.printlns right?

Please let me know your thoughts.

System.out.println in gui--- question

Hello People.
First of all, I'm new to the forums, so if it doesn't belong here, plese tell me where to post questions like this.
The Problem:
I have a GUI and another class,which contains the Program.
Here's the code of my class:
int Battle(String CharName) {
          System.out.println(CharName + " Is fighting agains a monster");
          while (CharHP > 0 && MonsterHP != 0) {
               MonsterHP = MonsterHP - CharDmg;
               System.out.println("The monster has " + MonsterHP + "Hitpoints left ");
               CharHP = CharHP - MonsterDamage;
               System.out.println(CharName + " has " + CharHP + " Hitpoints left");
          if (MonsterHP == 0) {
               System.out.println(CharName + "Has lost the fight!");
               CharEXP = CharEXP + 20;
               System.out.println("You have gained " + CharEXP + " Exp");
          if (CharHP == 0) {
               System.out.println("You have lost the fight!");
          return CharHP;
     }So what would be the code to print all the "System.out.println's" here into the gui test area?

System.out.println in iPlanet 6.0

Hi..All,
The System.out.println stmt would print out the message when using iPlanet4.x whereas its not doing so when using iPlanet6.0(solaris). What changes/modifications do I have to do to achieve the same.

Add the following line to your magnus.config file and restart the server.
