Supressing the Java command window ???

Hi,
How do I get rid of the command window from where I start my Java Application ?
Even if there is a way what will happen to all the System.out.println() calls in my applicatio ?
Thanks in advance.

You can just not start the Java application from a command window or batch file. The easiest way to do this is to create an executable JAR file which a person (on Windows) can just double-click. Do a search on "executable JAR".

Again...Suppressing the Java Command Window

Hi,
My invoking my java application with "javaw", I'm able to suppress the command window.
None of the System.out.println() is now seen. Thanks for that.
But there is another problem that I see.
In my application, I run some batchfiles using the Runtime.exec
with the "cmd" parameter. This is making a separate command window
pop up from no where.
This pop up is happening for every call I make ? Can this be avoided at all ???
Or should I live with it ??
Many Thanks

You may have to live with that cause cmd runs with its own window. I haven't used this very much but for the little I have done, I can't ever seem to get it to hide, unless you decide to use START to run the activity and then call EXIT in the batch file so it closes as soon as it is done.

Using the "java" command in Java 1.4.1

Hello..
I don't seem to be able to run any application that should run with
the "java" command in Java 1.4.1. Everytime I use "java" I get the "java.lang.NoClassDefinitionError"
Even running this simple program doesn't work:(
package chapter10;
public class test {
public static void main(String args[]) {
System.out.println("Hello WORLD!!");
}//end class
when I run: "java chapter10/test"
I get the following message:
"Exception in thread 'main' java.lang.NoClassDefinitionError: chapter10/test"
And the sam happens to any other class when I try to run it:(
The "javac" command works fine:) but the "java" is giving me a hard time:(
I would appreciate any suggestions or answers to this problem:) THANK U

See if this explanation helps.
Assume that your programs are part of a package named divelog, which is specified by the first line in each source file: package divelog;
Also assume that this directory (C:\javaT\myWork\) is part of the CLASSPATH list of directories.
Also assume that all the source files reside in this directory structure: C:\javaT\myWork\divelog\
Then a statement to compile a source file Named Divelog.java is:
C:\JavaT\myWork\>javac divelog\Divelog.java
Explanation:
Java starts looking for classes in the directory(s) listed in the classpath. In this case, one of the directories should be: C:\JavaT\myWork\ since it contains your divelog package.
Compiling
A class can either be part of a package (ie, no package statement at the top of the class.), or not.
If the class is not part of a package: Its source file needs to be in one of the classpath directories. To compile you use the command: javac SomeFile.java, from within the classpath directory that contains the file.
The class is part of a package (this case): The source file must be in a subdirectory structure that starts in one of the classpath directories. The subdirectory structure must match the package statement.
So, you generate a directory structure C:\javaT\myWork\divelog\ which is the [classpath directory + the package subdirectory structure], and place Divelog.java in it.
Then from the classpath directory (C:\JavaT\myWork\) use the command: javac divelog\Divelog.java
This creates a file, Divelog.class in the divelog directory. (The following is where people tend to get lost.) The correct name now, as far as java is concerned, is the combination of package name and class name: divelog.Divelog (note I omit the .class)
Running
To run a class that's not part of a package: From within the classpath directory that contains the class. use the command: java SomeFile
To run a class that is part of a package: From within the classpath directory (C:\JavaT\myWork\) use the command java divelog.Divelog (Note that this is analogous to the command for a class not in a package, you just use the fully qualified name)

Open a command window and send some keystroke to the opened command window

Hi All,
I am trying to open command prompt and send some key stroke to that command prompt. Here I am using Robot to send keystroke. But the problem is, the keystrokes are not sent to the prompt. I guess I need to activate progamitically the command prompt to accept the keystrokes . Please find the code below ( as I did).
try
String command = "cmd.exe /c start";
Process child = Runtime.getRuntime().exec(command);
Robot robot = new Robot();
Thread.sleep(5000);
String lol = "indranil";
for(int i=0;i<lol.length();i++)
robot.keyPress(lol.charAt(i));
int g = lol.length() - 1;
robot.keyRelease(lol.charAt(g));
catch (Exception e) {}
I guess I am doing some mistake here while sending the keystroke/openning the command prompt. Can anyone please help me how can I open a command window and send some keystroke to the opened command window. I am in fix.
Thanks,
Indranil

The first thing to do is read the API and examples for the Robot class.

I am missing Speakable Items in the Speech commands window

Hi there,
I just realized that I can't command any speakable actions, I have NO commands in place in the speech commands window, and my -/user/library/speech/speakable items folder is empty.
I am administrator and single user of my Mac
I have no idea why it is empty, i suppose it has been like this from the day I have installed OSX, years ago now.
I have tried to install OSX from scratch on a separate partition, and of course, with this new system, the commands are in the proper place and the speech commands works.
However, when I re-import my profile with the SetUp assistant from the original partition, all the commands are lost, since the Speakable items folder is under my personnal home directory, it has just been copied, and left empty by the assistant with all my profile.
Can anyone help me and tell me which items i should copy from/to where to have the speech commands working ????

Same here.
I copied the Speakable Items folder from my old computer, but it still won't work.
I hope you get an answer!
ANSWER! - I had the same problem. Open up your Speech and turn off speakable. Than go to commands select address book click on configure if there is any Name that has (NUL) uncheck it. than go and turn on speakable again. Your commands should be there!
It worked for me! Good Luck!

Error when I execute an application with the java command in a DOS prompt

Hi:
I have a trouble. I edit the most simple program in Java: hello.java
In DOS prompt, I compile the program. The result is the file hello.class
c:\> javac hello.java
However, I try to execute this program with the command java
c:\> java hello
and the DOS prompt send me an error like this: Java.exe has a problem and must be closed.
I press the option "Don't send". After this, the DOS prompt returns empty and it doesnt execute the application:
c:\>
By the way, in an IDE editor like Gel, the file hello.java is compiled and executed correctly without problems.
I edited other simple Java files, I compiled them succesfully and I can't run them in a DOS pormpt. The result is the same dialog box: "Java.exe has a problem and must be closed".
The question is: Why don't these programs run in a DOS prompt?
My Operating System is Microsoft Windows XP and the Java compiler version is: 1.6.0_13
Thanks in advanced.

Where can I set the window dimensions for the "Java Applet window"?

Hi,
When I run a form on the web, the Java Applet is loaded and the form appear in the window. But "base window" have gived dimensions indifferent what dimensions has the window of the form which I run.
So, where can I set the dimensions of the "core window" which is behind the MDI window of the application?
Thanks in advance,
Eugen

Eugen,
in formsweb.cfg you will find parameters "width" and "height". You can set absolute values in pixels or "relative" in percent.
width=800
height=600
or
width=100%
height=100%

The "java" command wont work

Hi,
I have been running my java programs from the console all this while by typing "java " and then the complied class name and everything had been going on fine until this moring when I tried running a prog I'm currently working on and it gave the kind of error message you get when your class file doesnt have a main method in it i.e exception in"main" thread noclassdefintionfound bla bla bla. I tried several other programs that had always been fine and still the same thing. I've also tried installing java still the same thing.
the javac command and java command are both recognized but it is like it no longer reconizes all the class files
pls how can i get my prog to run again
thanks
abiose

Check whether all those files are available in the classpath in your console. Check for the variable CLASSPATH in the system environments and find if it contains the path where all your class files are residing and try it out.

Where is the documentation on the Java command line options.

I know you can get them by running java.exe, but does Sun have a web page with a little more detail?

Googling for
java command line options site:java.sun.com
Found this for 1.4. I imagine you should be able to find something similar for 5.0.

Adding more statements to the sql commands window

Hi, I'm using oracle database express edition10g and I just started using oracle.
And I'm having a problem adding more then one statement inside the sql commands gui window.
I write:
CREATE TABLE "testTable" (
     "field1" VARCHAR2(2),
     "field2" NUMBER(2,0),
     "field3" NUMBER(2,0),
     CONSTRAINT "Test_PK" PRIMARY KEY("field1")
Oracle reports: table created
I write
DROP TABLE testTable;
CREATE TABLE "testTable" (
     "field1" VARCHAR2(2),
     "field2" NUMBER(2,0),
     "field3" NUMBER(2,0),
     CONSTRAINT "Test_PK" PRIMARY KEY("field1")
Oracle reports: ORA-00911: invalid character
I remove the ; char
ORA-00933: SQL command not properly ended
I look in the help files and it sais that ; / and nothing is allowed to end a operation.
I gues ; is a valid char so it's reporting something else?
I tried pasting my code inside wordpad and even retyping it. Mayby I have a hidden char? =>same error.
When I run drop and create seperatly it works.
When I run both sql statements inside sql+ it works
What m I doing wrong?

To run multiple SQL in one shot, you need to save them as SQL batch file,
Save your statements as recreate.sql
DROP TABLE testTable;
CREATE TABLE "testTable" (
"field1" VARCHAR2(2),
"field2" NUMBER(2,0),
"field3" NUMBER(2,0),
CONSTRAINT "Test_PK" PRIMARY KEY("field1")
);Then call it from SQLPlus,
@recreate.sql

You could try upgrading to SQL Developer 3 which is more up to date.
Try running <sqldev>\sqldeveloper\bin\sqldeveloper.exe from a cmd window and see
if there is any more information.
If you type java -version in the same command window what do you get?

NOT displaying the command window when running applications

hi
i'v been seraching all over the web for a way to get rid of the command window (dos shell) that appears when running a java swing based application (or any other). i currently have a batch file that loads all the required libraries into the class path and then calls the application's main class. problem is, the DOS command window stays open. is there any way to have it not display (obviously without losing my program in the process). at the very least can it be minimised automatically (just the dos window)?? though i think getting rid of it all together would be best.
i would really love some help on this... very over seeing that dos window displayed...
any help would be greatly appreciated.... thanks heaps
