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);
HTH,

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...

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.

The Member Feedback forum is for suggestions and feedback for OTN Developer Services. This forum is not monitored by Oracle support or product teams and so Oracle product and technology related questions will not be answered. We recommend that you post this thread to the Application Server-General forum. The URL is:

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.

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.

ORA-04030: out of process memory when using Java Stored Procedures

Hello,
I have a problem using Java Stored Procedures in Oracle 10g.
My Java application performs http posts to a webservice and the response is parsed in order to populate some DB tables.
There is a scheduled job which calls the Java Stored Procedure every x minutes.
No matter of the 'x minutes' values - after about 160 - 200 calls I get this error:
ORA-04030: out of process memory when trying to allocate 1048620 bytes (joxp heap,f:OldSpace)
ORA-04030: out of process memory when trying to allocate 2097196 bytes (joxp heap,f:OldSpace)
The job stops just while is posting the http request. The weird thing is that almost each time the first http post request I get this error:

Can be a problem with JVM threading under Oracle ?

The server prcess failed to allocate more memory for large objects ( in Oldspace).
If you Google ORA-04030, you will see several recommendations to work around this.
The Java VM in the database already has HttpClient, i don't know why you are loading the Apache HttpClient but this might not be the surce of the problem.

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!!

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

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?

Is it possible to use iFS API within java stored procedure?

question:
is it possible to use the iFS API for file handling
within a java stored procedure (which is invoced by a trigger)?
is there an "elegant" workaround if it is not possible?
problem:
my java code using the iFS API works fine outside
the java stored procedure
but invoked via trigger as java stored procedure
it throws following exception:
IFS-20102: Unable to start service (IfsDefault)
i am using:
oracle 9.0.1
oracle internet file system 9.0.1.1.0
windows 2000
thanks

thanks for your help
i looked through the applications developers guide
the basics behind advanced queueing (as far as i understand) is:
program A inserts a message into the queue - and program B gets message from the queue and processes it
question 1:
but what is the difference between advanced queuing and a queue i create by myself
(simply with a database table) and let application B (which runs in a loop)
check if the queue is filled
or am i missing something important which makes advanced queuing more practicable for my problem?
question 2:
you wrote about advanced queuing support in iFS 9.0.3, but the newest version i found was iFS 9.0.2
did you reffer to the advanced queuing mechanism in general or to a spezial queuing feature in iFS 9.0.3?
thanks

System.out.println not showing up in the console

Thre problem still remains.I'm very sure that the EJB

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?

Using System.out.println() in Scrapbook

I am working through some tutorials on formatting numbers:
http://docs.oracle.com/javase/tutorial/java/data/numberformat.html
I am trying to use scrapbook. I can't seem to get the result I am wanting from System.out.println("Hello world")...I get null. To be specific I am trying to inspect:
int i = 461012;
System.out.format("The value of i is: %d%n", i)In this case I get:
java.io.PrintStream@46b372
Something tells me that System.out.format can't work in a scrapbook. Is there a way without writing a main and running as java?

It seems that the format method returns the PrintStream (allowing you to chain method calls), and the return value is being printed.
You would get the output you're looking for, if you use the String.format() method, since that'll return the formatted String.

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.

Which toString() method does System.out.println() call?

Which toString() method does System.out.println() call? I know that if I did something like System.out.println( new myClass() ) that the toString being called would be that of the myClass class.
My initial thought about this was that System.out.println() is the equivalent of System.out.println( new Object() ) but I remember trying that in a test program and it gave me a myClass@some_hash_code type of message when adding the new Object() part within the System.out.println().
Could someone please tell me which toString the System.out.println() statement calls? Also, it would be great if an elaboration follows :).
Any input woudl be greatly appreciated!
Thanks in advance!

In one method call you pass no parameters in the other method call you pass one parameter. How could you possibly think that they would do the same thing?
Could someone please tell me which toString the System.out.println() statement calls? Also, it would be great if an elaboration follows :).Yes. The toString of the class of the object which you pass to the method. If that class does not have a toString method it uses the toString method it inherits from the parent class. If the parent class does not have a toString method it uses the one inherited and so and so on all the way up to the Object class.

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