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

I have jave 7 I'm trying underscore option in String. as String strNum = "1000_000";System.out.println("..abc..." Integer.parseInt(strNum)); but getting error. could you please help in this?

Hi,
There is a new feature added in java 7 on integer, called as underscore '_" and it is working fine
if it is a normal int variable but if it is coming with String jvm throw the error.
if any one of you have java8 installed on your PC can you check this is working on that version.
int a = 1000_000;
String strNum = "1000_000";
// System.out.println("..abc..."+ Integer.parseInt(strNum));
System.out.println("a..."+a);
Thank you,
Shailesh.

what is your actual question here?

SQL>call dbms_java.set_output(....);
but when i test it within the jdeveloper9.0.3,it can't be print,why?

Can't run java apps with System.out.println on any builder.

Hello,
I'm currently using Vista RC2, which is the immediate problem.
Classes with System.out.println won't launch the console window. As I'm a student and practicing on these steps, I do have quite a problem on my hands. I click on run, build succesfull, nothing happens.
I have tried Netbeans and Jcreator, and gave up on trying different builds, as I reckon I'll have to find some other way to counter this; any way to get println messages working in vista?

It is run as a desktop app, and other runs with commands such as JOptionPane do function, only the println windows don't appear at all. So I think JRE is installed and working.
I did notice there was one command for input where I'd be able to enter it at the bottom of Netbeans.
Like just now I clicked build and run for the following code
import java.util.*;
public class FirstProgram
    public static void main(String[] args)
        System.out.println("Hello out there.");
        System.out.println("I will add two numbers for you.");
        System.out.println("Enter two whole numbers on a line:");
        int n1, n2;
        Scanner keyboard = new Scanner(System.in);
        n1=keyboard.nextInt();
        n2=keyboard.nextInt();
        System.out.println("The sum of those two numbers is");
        System.out.println(n1+n2)
}Resulting in a brief flash of "input" in the output window (which is below the coding window) and it dissapears. But this also occurs when I don't include system scanner code.
Using commands in cmd
java -jar "C:\Users\Alegis\Netb\MyApp\dist\MyApp.jar"
Does not yield desired results either. Nothing happens.

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.

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,

How use system.out.println with a Java Swing Applet?

Hi guys,
I was just wondering what can I use to view output on the Java console with a Java Swing Applet?
At the moment I'm using a JTextArea within the Applet for debugging but I want output to appear in the browser java console but system.out.println doesn't work.
I'm viewing the Swing Applet on Netscape 4.7 browser.
Any ideas?

System.out.println()s work fine! I'm guessing that your problem is that you are looking at the wrong console window!
You're using the Java Plug-in, right? On Windows, go to your Control Panel and double click "Java Plug-in". You should find a checkbox option to "Show Java Console" - make sure this is checked. Next time you fire up you JApplet, you should see a Java Console window popup.
Hope this helps!

Hi, i've done all described in the posts, but i
don't know how to call the servlet, using the web
browser, and more, how can i call the servlet frrom
a button action? or hyperlink?
nks for the helpOk, I am not sure what you are trying to do. For these events you can
use the SessionBean. What do you want the servlet to do that the session bean can't?
I use the sessionbean because I don't know how to receive or respond to xmlhttpreq messages directly in my sessionbean. If you just need the standard http req/resp it doesn't seem like a servlet is needed.

Some Questions about Sun Java Studio Creator IDE

I am quiet new to the IDE, but I experienced some
behaviours I do not actually understand.
I hope I can get some help here.
Sun Java Studio Creator Update 9
Each time I change the font size and type using the
"Advanced" option of the IDE the font I changed correctly.
But after closing and restarting the IDE the fonts are set
back to the default undoing my changes.
Is there a way to use code completion for the jsf tags within jsps ?
I know that there are code clips for adding jsf components to the jsp,
but (coming from eclipse ide) I'd appreciate a feature like the code completion for the jsf components. If there is a way by configuring, how can that be acchieved ?
Trying to add a "taglib declaration" to the jsp e.g. "<%@taglib uri="..." prefix="..." I get the warning that the tags of the xml must be welformed.
How can I add those taglib declarations correctly ?
Using the "File System View" after each change made e.g. to a jsp the
tree collapses and I have to navigate to the tree again to find my resources.
Is this common behaviour or to be configured ?
Thx for any support.

Hi,
1. The changes made to the font size and type are indeed getting reset in Creator update 9. However this behaviour is not seen in the latest version of Creator which is Creator 2 EA 2. The final version of this will be available very soon and we encourage you to try the new release which has lot more features and lot of bug fixes. For more details please visit:
http://developers.sun.com/prodtech/javatools/jscreator/ea/jsc2/
The following thread will explain about the tags and how they should be well formed:
http://swforum.sun.com/jive/thread.jspa?forumID=123&threadID=47615
The behaviour of the File System View was encountered in Creator update 9 as you have mentioned. Once again this behaviour was not see in the latest version Creator 2 EA 2.
So we recommend you to try out the latest version.
We appreciate your valuable feedback and thank you for the same.
Cheers

Can't install Java Studio Creator 2!!!

Hello,
First of all I just want to say that I tried a lot to solve this problem myself, I read lots of help and visited lots of website, but couldn't solve this problem !!!!!!!
I downloaden Java Studio Creator 2 and trying to install it, but while installing the installation just stops without saying anything!!
I downloaded it several times now coz I thought the file was corrupt, but it didn't work!!.
I never had the Creator before so the other tips wouldn't work!!!
At the end of all wizard screens when it should install the Creator 2 the installation exits withouts giving any messages and does nothing more!
Could someone please give me some advice on how to slove this problem?
Thanks in advance

You are probably running out of Ram, and maybe even low on hard disk space to. The minimum system requirement is 512 MB of Ram. I am running 768 MB, but even with that I am virtually maxed out with Creator, a database, and the App server running. Those three items are really needed for development, and I have noticed that if I do actually max out the RAM the Appserver will not start and I have to reboot.
I would say for development with creator you really need 1 Gig of Ram, which I will be upgrading to in a couple weeks.

Is there a way to make system.out.println() scroll down as it goes?

I am writing a program where I want to be able to read what's printed out in the console of my IDE through System.out.println() as the program runs/after the program runs. However, right now I run the program, the message prints out, and then when I go to read it the scroll bar is all the way up so I can see only the top of the print-out (the first thing printed out). Is there any way I can get the console to scroll along with the text, kind of like floating boxes you see on various websites for various reasons? In other words, can I get it so that when I look in the console at any given moment of the program running, I am looking at the newest text printed out (the text at the bottom of the "page")? Thank you!

That would be an IDE problem and not a Java one. You could redirect output into a text file so you can read at your leisure and scroll up and down as much as you like.

32-bit JDK 7 System.out.println not working in IDE

Hi folks,
I have a 64-bit Windows 7 OS.
Due to 3rd party library/jar dependencies, i had to install the 32-bit Java JDK 1.7 and Eclipse IDE.
I also installed NetBeans.
So i have a 64-bit OS and am running 32-bit Java JDK/JRE & IDEs.
The problem I am having is that my program's System.out.println("...") statements are not outputting strings to either IDE debug console.
Executing the compiled program from a command line/prompt produces the expected string output.
The basic "Hello, World" program is enough to cause this behaviour to start occurring.
I have not manually / intentionally changed any IDE-specific Debug Console or Windows environment settings.
One caveat: This same environment has worked successfully in the past ?! Yes, this is one of those "..it worked last week & yesterday and today it isn't and i swear i didn't do anything..." issue.
Thoughts ?

Thanks for the reply.
The 64-bit versions of Java & Eclipse were installed first.
When i discovered I had to use the 32-bit versions, i un-installed the 64-bit ones & installed the 32-bits.
Even after that initial un-install 64-bit/install 32-bit process, it was working.
I have also been installing the Windows 7 64-bit OS updates when i am informed of them.
I'm not sure if any of these would affect how the Eclipse / NetBeans IDEs behave.
Behaviour has been inconsistent.
Initially it was always working.
But over the past several days, it has been working less and less.
I don't have any large data structures.
This isn't a large complicated program, couple hundred lines, so i highly doubt that i'm doing anything to the resources, but something has changed.
The main project I am working on takes command line parameters, does some initial processing, produces output using System.out.printlns [SOP] then depending on the parameters, branches into 2 different processing paths, let's call them A & B. Each of these processing paths also use SOPs. When i run the program in the IDE going thru path A, sometimes the initial SOP statements will work and the SOP statements specific to path A will also work. If i immediately change the parameters to go thru path B & re-run it, not even the initial SOP statements before the branching decision work.
I've tried doing System.flush()s too - no affect.
I haven't tried the re-direction option to a file option you mentioned yet.
It always works from a command prompt - that is telling me that the Java SOPs are working properly, correct ?
Inside an Eclipse or NetBeans IDE, SOP output to the debug console is inconsistent.
Running from a command prompt, the SOPs always work.
It'd help to know if this an IDE issue, a Java issue, a Windows 7 issue so i can narrow down where to try and correct the situation.
I have a Windows XP VM set up, i'll try running the program there and see if there's a difference.
Thanks for your reply.
