Getting System.out statements to be displayed in a text field

Hi,
I'm trying to direct the system.out.println stream to a text field in Swing so that when any system.out.println statemetns are executed the text field will display them as well. I would imagine there has to be some kind of event listener. Any ideas?

How to get System.out msg displayed in logs

Running SJSWSEE6.1 SP5 on Solaris
How do I get the System.out.println messages to display in the Web Server 6.1 error/access log??
Thanks..

Hi,
In your server.xml, check that the properties 'logstderr' and 'logstdout' are set to 'true'. The messages will then appear in the errors log file.
<LOG file="<path to errors file>" loglevel="info" logtoconsole="true"
usesyslog="false" createconsole="false" logstderr="true" logstdout="true" logvsid="false"/>
Also, see docs at http://docs.sun.com/source/817-6248/crsrvrx.html
Hope this helps.

How do I get System.out.format to print out doubles with the same precision

Using the System.out.format, how do I print out the value of a double such that it looks exactly like it does if it were print from a System.out.println.
For example, take the following code:
double d = 12.48564734342343;
System.out.format("d as format: %f\n", d);
System.out.println("d as sout: " + d);Running the code, I get:

d as format: 12.485647
d as sout: 12.48564734342343

The precision of d has been lost.
I could bump up the precision as follows:
double d = 12.48564734342343;
System.out.format("d as format: %.14f\n", d);
System.out.println("d as sout: " + d);That appears to work, I get:

d as format: 12.48564734342343
d as sout: 12.48564734342343

However, that solution fails if d has a different precision, say 12.48. In that case I get:

d as format: 12.48000000000000
d as sout: 12.48

So how do I get System.out.format to print out doubles with the same precision as System.out.println?
Thanks..

Interesting, but this is not what I am looking for...Your original question was "how do I print out the value of a double such that it looks exactly like it does if it were print from a System.out.println", and you've been told how to do that (although the pattern given by sabre may be a bit excessive - you should only need 15 '#'s).The initial phrase from my question was "Using the System.out.format, how do I..".
It's worth remembering that, unlike the Format hierarchy, 'format()' is NOT native to Java. It's a convenience implementation of the 'printf()' and 'sprintf()' methods provided in C, and first appeared in Java 1.5. Those methods were designed to produced fixed-format output; 'println()' was not.Perhaps it is the case that this can't be done.
Furthermore, Double.toString(), which is what is used by println() does not produce the same format in all cases; format("%.14f\n", d) does. TrySystem.out.println(1.8236473845783d);
System.out.println(1823647384.5783d);and you'll see what I mean.I am fine with that. It still displays all the precision.
I am simply looking for a way to quickly print out multiple variables on a sysout while debugging. I want it as syntactically sweet as possible. System.out.println can be a pain when outputting multiple variables like the following:
"System.out.println("a: " + a + "; b:" + b + "; c: " + c);"
For some reason, my fingers always typo the plus key.
I was hoping that System.out.format would be easier,along the lines of:
"System.out.format("a: %f, b: %f, c: %f\n", a, b, c);"
From a syntactical sweetness point of view, it is easier. However, the %f on doubles truncates the precision. I figured there must be a way to get the full precision.
DecimalFormat is syntactically sour for this purpose, as you need to instantiate the DecimalFormat.
fwiw I have enjoyed reading the suggestions in this thread...

How to get data from list of values (LOV) to be displayed in a text field ?

Hi guys,
I am very new to Oracle APEX so please spare me if it is a silly question. How can I get the selected values from a set of list of values (LOV) displayed in a text field (or text area or so) ? Fox example, in my form I create 4 items: STATE, COUNTY, STREET, ZIPCODE and all of them are LOV (list of values). I also create 2 buttons (ADD & REMOVE). Then I create a test field (or text area name SELECTED RECORD). Now here is what I want to do with my form:
When I set the values for all 4 fields, I will click on the ADD button then I want those values be displayed in the text field.
For example, if the selected values are:
STATE = Alabama
COUNTY = Abbeville
STREET= 1 Street
ZIPCODE = 36310
And the ADD button is pressed. Then in the text field I want it displays like this:
Alabama,Abbeville,1 Street,36310
If I choose other values and click ADD again, a new line will be added into the text fields (text area). If I click the REMOVE button, then it will clear those two line in the text field.
Would it be possible to do it? Any help will be greatly appreciated. Thanks in advance.

If you can live with the page being submitted and refreshed, make your ADD button do a submit with a request value of ADD and make your REMOVE button do a submit with a request value of REMOVE.
Then create two computations (one firing with a condition of Request = ADD and the other firing with a condition of Request = REMOVE).
In the ADD one, concatenate the values together into the text area (most likely a PL/SQL computation wiill be what you want). In the REMOVE one, set it to null with a PL/SQL computation.
If you want it done without submitting the page, make the buttons each do a redirect to a URL but instead you will have to write two short javascript functions in the page HTML header to manipulate the field values. Each button would call each javascript function in an onclick event.

Need help displaying data in text field... Help?

i have this code:
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.events.Event;
import com.adobe.serialization.json.JSON;
var loader:URLLoader = new URLLoader(new URLRequest("https://api.twitter.com/1/statuses/user_timeline.json?screen_name=ScottMitchell"));
loader.addEventListener(Event.COMPLETE, loadComplete);
function loadComplete(e:Event):void {
 processData(e.target.data);
function processData(data:String):void {
 var tweets:Array = JSON.decode(data) as Array;
 trace(tweets[0].text);
It works, in the output it tells me the tweets.
but i need it to be displyed on the app, i need to no how to do this, someone pointed me in the direction of using a item renderer extended from sprite?
But really all i need to do is display it in a text field, all i want to do is display the data.
Can anyone help???
I know this is probably simple and i did try to figure this out on my own, but had no luck.
All help is appreciated.
Many thanks in advance.

you can always use an array if there's no pattern to your positions:
var positionA:Array=[ [100,20], [2,222], [55,2], [201,111], [78,23] ];
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.events.Event;
import com.adobe.serialization.json.JSON;
var loader:URLLoader = new URLLoader(new URLRequest("https://api.twitter.com/1/statuses/user_timeline.json?screen_name=ScottMitchell"));
loader.addEventListener(Event.COMPLETE, loadComplete);
function loadComplete(e:Event):void {
 processData(e.target.data);
function processData(data:String):void {
 var tweets:Array = JSON.decode(data) as Array;
for(var i:int=0;i<5;i++){
var tf:TextField=new TextField();
addChild(tf);
tf.multiline=true;
tf.width=300;
tf.text = tweets[i].text;
tf.autoSize="left";
tf.x=positionA[i][0];
tf.y=positionA[i][1];
nextY+=tf.height;

Single or multiple check box values displayed in a text field

My apologies, this may be a duplicate discussion.
I'm using the following script to display the values of check boxes in a text field. I would like the word "and" to separate the values if two check boxes are selected. If more than two boxes are selected I want the values to be separated by a comma and then the last value be separated by "and". Example of two check boxes selected: A and B. Example of two or more: A, B, C, and D. Can this be done?
form1.page1.page1SF.programs::calculate - (JavaScript, client)
//displays the values of check boxes named programCB
var aChkBx = [];
var vChecks = programCB.all;
for (var a=0; a<vChecks.length;a++){
if(!vChecks.item(a).isNull) {
aChkBx.push(vChecks.item(a).rawValue);
this.rawValue = aChkBx.join(", ");

Image not displaying with HTML text field

I am trying to display am image within
flash using CS3.
I have a text field with the following code.
feedback.htmlText = "<img src='Logo_small.png'</img>"
nothing displays. The image and flash document are at the same level, so that is why I am using a relative link. Do I need to use a full (absolute) link to the image?

That's not properly coded html...
feedback.htmlText = "<img src='Logo_small.png' />";
image tags do not have a closing tag and you didn't close the opening tag if they did, so it would still fail.

Not getting System.out.println output in Web Start Log File

I am new to this but I'm running through the examples in Mauro Marinilli's "Java Deployment with JNLP and WebStart" and the install-win and install-win2 examples are not writing properly to a user-specified log file on my desktop (chosen location). I have several versions of j2re/jre installed on my client computer and have started several of the javaws.exe files on my computer to specify that I wish to Show Java Console and Log Output but
1) no Java console pops up when I subsequently run the JNLP from my web server
AND
2) no log file is written
I do see the batch file left in place for install-win2 so I believe that the application is being run (such as it is... lol)...
Any ideas what the problem might be? All reasonable suggestions (i.e. not PEBKAC) welcomed...

How do you make the button to be displayed beside the text field?

I need help on doing this for a company. As of above subject.

In the intern's defense, that documentation isn't what I would call a "quick read." It's virtually >impossible to assimilate all the voodoo in one gulp. And the whole branches, buttons, items and >layout stuff is pretty frustrating. I'm just getting started, and I can sympathize with the tone of >voice. I couldn't disagree more......
In my experience, a prerequisite of learning any computer language or system is reading the associated documentation. If you're the sort of person who likes to just dive into writing code without understanding the fundamental basics of how the language/system works then you're going to encounter lots of problems no matter whether you're using Apex, Java, Perl etc.
Nobody is saying that you should spend days and days reading the documentation as though you were preparing for an exam, however if you don't take the time to learn some of the basic concepts then the only person who is going to suffer is you (and also perhaps the users of your system!).
If you feel the documentation is too big for you to take in in one sitting, then break it into chunks. Set yourself a few little mini-projects to do, with each one using a different piece of functionality (for example reports, branches, collections etc).
The more you put into learning (and using) Apex the more you will get out of it.

Display filename in text field

Hi, A simple question; how can I insert the pdf filename (without the file path) as a read only value in a text field. As this is not available as a Runtime property is there a script for this?
Thanks!
Sam

In the initialize event for the text field, add the following client-side JavaScript:
this.rawValue = event.target.documentFileName;
Note, when you preview the PDF in Designer you will see an odd file name like _13fs18f3v9eeb3qs.pdf. When the PDF is opened in Reader or Acrobat you will see the real file name.

HTML links won't display in Dynamic Text Field

I am loading external text files in dynamic text fields on my
webage. These texts contain html links (<a href="page.html"
target="_blank">Click Here</a> and I have "render as HTML"
on and "selectable" off in my dynamic text field. Also, I am
loading a CSS file. Not only do I not have a hand cursor, but I do
not even have any of the text from that piece of html code down.
What is going on with this? Please respond asap, as I have been
struggling with this for a day now. Here is the Actionscript for
loading the CSS:
var flash_css = new TextField.StyleSheet();
flash_css.load("styles.css");
flash_css.onLoad = function(success:Boolean) {
if (success) {
zloc_txt.styleSheet = flash_css;
} else {
trace("Error loading CSS file.");
var zloc_lv:LoadVars = new LoadVars();
zloc_lv.load("zloc.txt");
zloc_lv.onLoad = function(success:Boolean) {
if (success) {
zloc_txt.text = this.content;
} else {
trace("unable to load text file.");
zloc_txt.html = true;
zloc_txt.editable = false;
_global.styles.TextArea.setStyle("backgroundColor" ,
"transparent");
_global.styles.TextArea.setStyle("border styles" , "solid");
Here is a sample of the text file code:
&content=Northwest Arkansas
Locations
121 Main St.
Russellville, AK 77801
(626) 111-1111 
<html><a href="
http://www.mapquest.com"
target="_blank">Click Here for Driving
Directions</a></html> 
Thanks for the help,
Chuck

The error is here:
zloc_txt.text = this.content;
Even if you rendered the textfield as HTML, you still need to
tell flash that the variable you are inserting is HTML. Therefore
you need to use the htmlText property.
zloc_txt.htmlText = this.content;

How to display a record count in a text field?

I am trying to return a record count of a query and place that count in a text field on my search page in APEX. I have that text field defined under Items on the search page. How do I get a query record count to display in my text field?
Thanks,
John

Hi Dan,
Thank you for your reply and yes I was able to select "Source Type" and "SQL Query". The SQL expression I used was:
SELECT COUNT(ID) FROM master_table;
This worked great to count the total number of records from the master_table. However what I am trying to do is to get a record count each time I complete a search from my search page. I have input fields on this page and a GO button which executes the query. The SQL query is location in one place under Regions/Display Point. My display field on my search page is named P16_COUNT2 and I was trying to make this work inside the main query code. I tryed something like this, COUNT(ID) INTO :P16_COUNT2, to pass the record count each time I execute the GO botton to P16_COUNT2 field. This I could not get to work. Any ideas how to proceed?
Regards,
John

System.out and System.err How to get to show up in log

Does anyone know if there is anyway to get System.out and System.err

Trying to build and debug a JSP project is a complete nightmare when the
remote developers cannot see System.out or System.err messages from helper
classes.

System.out.println - Hello World Example

Hi All
I am using Apache Tomcat and trying t produce a simple output to the browser. Cannot get System.out.println to work. See code and out below:
begin code
<HTML>
<HEAD><TITLE>hello jsp</TITLE></HEAD>
<BODY>
<%@ page language='java' contentType='text/html' %>
<%
String message = "Hello World";
message = message + "\nAFTER";
System.out.println("BEFORE");
%>
<%= (message) %>
</BODY>
</HTML>
END code
--begin browser output
Hello World AFTER
end browser ouput
Would be grateful if someone could explain why the System.out.print statement cannot be seen in the browser output.
many thanks
Naresh

System.out prints to System.out. What that is depends:
In applets, (which the OP was not talking about) it is the Java Console.
In JSP, it's the same as any application by default.
You can change in Java what System.out prints to, but you don't often do this. But in JSP it doesn't print to the browser. JSP is not CGI, which does you the standard out as the destination for written data.

How do you change system.out.println colour?

Hi, I am developing some basic rmi client/server applications, I have an 2D array on a central server being read/written by remote clients. all the development is using system.out. statements at the moment (hopefully being replaced by GUI later) my question is when a client remote calls a read operation, and reads an array location, eg x3, y4 I want to print the location contents in a different colour to indicate the read, at the moment the displayArray() simply has nested for loops to cycle through the array and System.out.println statements to get it to the screen. I wonder is there a simple way to change the colour of system.out type statements? thanks for any help

I could be wrong, but I don't think that is possible. The System.out and other streams are just streams of characters, and doesn't contain any data about the characters. You could possibly get it to work if you knew which terminal the stream was going to and if the terminal had escape commands that could set colors. BBS browsers have that functionality, but I think that would be a hard path to follow.
If you are printing out a lot of data and need some color to aid it's readability, try printing directly to your graphic context:
Graphics g = getGraphics();
g.setColor(Color.white);
g.drawString("Hello",100,100);
