Opening an additional console in a Java program

Is it possible to open an additional console to be used similarly to
System.in/out from a Java program?
How?
Thanks for any help!

You can create InputStream(System.in) and PrintStream(System.out/err).

Opening a Word Document with a Java program in Windows

When running a Java program in Windows, is it possible to have a button where when it is clicked it will open a Word document?
If so, is it hard and can someone tell me how to do it??
Thanks

try this instead of Excel.exe you have to use Word.exe
1. Declare your button
               JButton butexlcom = new JButton("Carnet Offre");
               butexlcom.addActionListener( new ButExlCommercial(msgout));
               butexlcom.setBounds(215,510,110,30);
               c.add( butexlcom );
2. run your word document.
class ButExlCommercial implements ActionListener {
     private JTextArea msgout;
     public ButExlCommercial( JTextArea msg) {
     msgout = msg;
     public void actionPerformed( ActionEvent e ) {
          try {
               Runtime.getRuntime().exec("c:\\Program Files\\Microsoft Office\\Office\\Excel.exe NameWordDocument");
          catch(Exception en) {
               msgout.append( "\n*** PROBLEME WORD ***\n" );
}

How to close a open file at OS level using Java program

I want to find a way to close a file connection at operating system (Windows 2000) level so that another program can overwrite the file. Here is the background information:
I need to schedule a job to automatically update certain files. But, when someone is accessing the file, the update will fail until I manually close the file connection at file server ( I have the system administrator privilege). I want to write a Java program that can automatically close the open file like I do manually at file server. This program can be placed on the file server in order to the job.
Does anyone know if there is any way in Java that can do the job?
Thanks

It's up to the application that opened the files to close them. There are utilities you can use to list/kill process on the machine..but you have to ask yourself WHY is this happening in the first place? It's more correct to fix the REAL problem - having your apps shut down properly - than to write a utility to close files.
That said...java alone cannot do this. You would either have to use JNI to get native access to the system or use System.Runtime to call an executable that does the job for you.

Open a file in a running java program via double click

I have already implemented opening my program with the corresponding file after a double click in windows explorer or from the cmd line but how do you open a file into the program if it is already running as MS Word will open a .doc file in the current word instance if you are running it.
Thx,
Jim

Implement some sort of interprocess communication in your program. If you launch an instance, it can check whether another is running and pass a message to it telling it to perform the wished action.

Running Java program created with Eclipse plugin fails to open report

I created a CR 2008 report and using the Eclipse plug-in I created a Java program to drive data through the report and export the resulting reports as pdf files.
This process works just fine if I run the Java program in Eclipse. I copied the code to a server to run the application remote.
The program fails at the point of opening the Crystal Report. This is the error.
D:\src>java EDIInvoice
Current date : 2009928-
Report output name is : D:\src\report\Invoice2009928-45462829.pdf
com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: com/ibm/icu/util/Ca
lendar---- Error code:-2147467259 Error code name:failed
        at com.businessobjects.reports.sdk.JRCCommunicationAdapter.<init>(Unknown Source)
This is the code
public class EDIInvoice {
     private static final String REPORT_NAME = "D:
src
CR8Invoice.rpt";
     public static void launchApplication() {
     try
        FileInputStream in = new FileInputStream("D:
src
ghxInv.txt");
        BufferedReader br = new BufferedReader(new InputStreamReader(in));
        String strLine;
        Calendar cal = new GregorianCalendar();
        int month = cal.get(Calendar.MONTH);
        int year = cal.get(Calendar.YEAR);
        int day = cal.get(Calendar.DAY_OF_MONTH);
        String today = (year + "" + (month + 1) + "" + day + "-");
        System.out.println("Current date : " + today);
// Read the file one line at a time
        while ((strLine = br.readLine()) != null)
            String patternStr = ",";
            String[] fields = strLine.split(patternStr);
            String EXPORT_FILE = "D:
src
report
Invoice" + today + fields[1] + ".pdf";
            String Company = fields[0];
            String Invoice = fields[1];
            String PO_number = fields[2];
                   System.out.println("Report output name is : " + EXPORT_FILE);
     try {
//Open report.
     ReportClientDocument reportClientDoc = new ReportClientDocument();
     reportClientDoc.open(REPORT_NAME, 0);
     System.out.println("Opened the report");
As you can see the first 2 println statements worked fine, but the 3rd one failed. The program was not able to open the report.
Is there a reason the code can not run without Eclipse?

did you copy all the jar files? especially the jrcadapter.jar? please download the following sample and modify it accordingly:

How can I stop running java program in console ?

Hi , my name is Luck , I will explain :
- I have created java script which execute commands from cmd level
- In java script I'm starting *. bat file which retrieve information from system example : hostname > C:\test and then I'd like to load from the file C:\test this host name example : MyComputer
but the problem is that my script execute reading from the file C:\test before any information will be delivered to this file , how can make a system to wait until bat file will finish doing its task , please , if you know the answer post me back , thank you

I have created java script which execute commands
from cmd levelI'd be surprised if you did. You probably wrote a Java program. I never heard of Javascript being run from the console.
- In java script I'm starting *. bat file which
retrieve information from system example :
hostname > C:\test and then I'd like to
load from the file C:\test this host
name example : MyComputer???
but the problem is that my script execute reading
from the file C:\test before any information will be
delivered to this file , how can make a system to
wait until bat file will finish doing its task ,
please , if you know the answer post me back , thank
youWhat are you talking about? This isn't Java, this isn't Javascript, I have no idea what it is. It's already difficult to understand your problem description.

Opening Default TextEditor Independent of OS through Java Program

Hi All,
I need a small help, I have a requirement in my program. I need to open default Text Editor of OS through Java Program independent of OS.Now i am using java 5.0. Is this facility available in java 5.0 API or I have to use any third party API is required, if yes then please suggest�
I apologize for my poor English...
Thanks in Advance�
RamaDevi B.

The concept of a default text editor is not OS-independent. Linux doesn't have one. (Yes, a shell can have one via the EDITOR environment variable, but you can invoke a jar from a window manager's desktop without running a shell. Nor does mailcap really count, because that defines a text viewer rather than a text editor). As far as I'm aware, OS X doesn't have one. In fact, Windows is the only OS which I know to have one.

Help--How can I open only one java program at one time?

How can I open only one java program(same program) in Windows at one time?

In Java 1.5, you can use the JVM's own monitoring APIs to examine what other JVMs are running on the system, and what applications they're running.
It's general and powerful, but complex. The socket/file/whatever approach is cleaner, and probably more suited to your usage.
Don't bother trying to use the Windows task manager for this sort of thing. You have to write messy native code, and it isn't reliable after all that anyway.

How to compile and run java program at command console

can anyone tell me how to compile and run a java program at command console? I have installed JRE 1.3.1, and also have installed JBuilder 5 if it helps.

BufferedReader console = new BufferedReader( new InputStreamReader( System.in ) );
String s = console.readLine();
System.out.println("Hello : "+ s+" !" );

Opening a URL from a Java Program

Hi all,
Can I open Internet Explorer and invoke a URL from a Java Program. If it can be done, could someone please give a code for that.
Thanks in advance.

Did you try it like "start \"http://java.sun.com\""
or maybe
"start 'http://java.sun.com'"I've no idea whether that will work, but it would be the first thing I'd try.
