Running Dos Command using Java

How do i run a particular Dos command using a simple java class?

Process process = Runtime.getRuntime().exec( ... );
Search the forum. There are plenty of examples.

How can I run a dos command from java on windows 98, 95?

The usage of cmd.exe in the java program to run a dos command on windows 98. 95 doesn't work as the equivalent command is command.exe
But using the command.exe in the java program makes my program to hang.

hi,
As u mentioned, u cannot use the cmd.exe in win9x environment as cmd.exe is specific to windows NT, you can use the command.exe without any hitches.
for eg
java.lang.Runtime.getRuntime().exec("start command /K a.bat"); should run the batch file a.bat..
if the problem persists, try posting the snippet of code that you are using.

Run An OS Command Using Java?

I want to write a java class that does some Unix system maintenance. In particular, I want to read some data out of a database and then do some calculations to figure out which files in particular can be tarred and zipped. The database part is already handled (in other words, I can identify the files I want to take action on) but I'm not sure how to run an operating system command (e.g. "tar cvzf myfile file1 file2 file3") using java.

Running MS-DOS commands using Runtime.exec()

Is there any way to run the dos commands like copy and del from our java program? Actually I want to implement a visual console kind of thing and have to transfer the commands to the prompt and get the result string that is to be displayed in a JTextArea?
Please help me. It'll be very nice of you...thanks

I can help you in two ways:
o by telling you to run cmd.exe and pass the rest as parameters.
o by pointing out this is the wrong forum for you equestion.

Running a Batch file Using Java

hi All ,
I am executing a DOS batch file using the Java .
I am using it as
Process P;
Runtime rt = Runtime.getRuntime();
P = rt.exec("C:\\X12TST\\BATCH1.BAT ");
But in case BATCH1.bat have call to some other Batch File Say Bactch2.bat , i am not getting the output of BATCH2.BAT .
My Java Program exits as soon as it enters to the point where BATCH1 is calling BATCH2 using (call BATCH2.bat).
Any help is resolving the problem is highlt appreciated .
Please advise me if you have any alternative to solve the problem .
Thanx in advace

The Runtime.exec() should'nt be used with a .bat or .cmd file since .bat and .cmd are not really executable. I think the expected behaviour you experimentred is a process hang at the last command line of the .bat file.
Insert "echo XXX" or "net send mycomputer XXX" debug messages in your .bat, you'll see the .bat executes until last line. But the last one NEVER terminates, resulting in a hang in the Java thread doing a process.waitFor().
The only workaround (or right use of exec) is to call the cmd.exe (with FULL PATH OF cmd.exe SPECIFIED in the exec() call). An exec() calling C:\WINNT\System32\cmd.exe /C mybatch.bat should return properly, cause cmd.exe is a standard Win32 program that will be launched to interpret mybatch.bat then terminate.
PLEASE UNIX/LINUX USERS : report if the behaviour you get is the same on your plat-form, or if it is -one more- bug in win32 OS. Can you exec() a shell script direcly or do you have to exec() a "bash" or "ksh" or "csh" with you shell script as command line argument ?

Check if a service is running on remote IP using java

Hi all,
hope I'm posting to the right section of the forum anyway I was wondering if anybody would have an idea how I could go about doing the following:
I have added a dialog to our application, when i hit the Launch button is opens up a web browser with a url that gets passed in the code.
The url is the ip address followed by : followed by port number. The web page then displays that web page with login screen for the application running on that IP address.
Before I pass the url above to the code that opens the web page I want to be able to check that a service is running at the IP address and if it's not I dont want to open the web browser with the passed url. The reason I need to do this is that if the service has been unstalled from that IP I dont want to open a web browser.
Would anybody know how I could check if that service is running on that IP address remotely?
Thanks for your help in advance,
Valerie

The only way to determine if a remote service is not running is by waiting for an exception to occur when you're trying to connect to it. You could make your service so that it supports an is-alive request of some sort.

Long running reports using java servlets

Hello,
I'm running into a problem using java servlets to produce database reports and sending them back to the client browser as excel or html. The problem comes into play when the user has submitted two reports then goes to run a third and the browser hangs. I realized now that this is because of the two active connections that the user already has to the app server. Does anyone have any suggestions on how to get around this? I'm trying to now write the report to the server, and provide the browser with a url, but it seams as though the connection isn't totally closed even though I close the response printwriter.... Any suggestions would be greatly appreciated....

Unfortunately I dont have an answer to your question, but:
If the reports are large/long running, should they be generated on demand? You could schedule the reports to be generated every day, month or whenever appropriate, stored on the server and then quickly pulled by the user whenever needed.

Running unix command using java shows error

Hi All,
I am trying to run UNIX move command using Java exec method but its throwing error, unable to rename. Here below is the code i am trying to run to move all files from one directory to another directory. source and destination directory exists.
public class Demo
    public static void main(String args[])
        try
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("mv /home/demo1/* /home/demo2");
            int exitVal = proc.waitFor();
            System.out.println("Process exitValue: " + exitVal);
        } catch (Throwable t)
            t.printStackTrace();
}if i give "mv /home/demo1 /home/demo2" in exec method, its working, with * character its giving problem.
Please help me in resolving the problem.
Thank you

Characters like *, >, &, |, etc. are interpreted by the command shell--that is by the bash, zsh, etc. programs. When you execute a command with ProcessBuilder or Runtime.exec, you're not going through one of those shells, so their interpretation of those characters is not available.
In your code, the character * is being delivered directly to the mv command (which doesn't think * is anything special), as opposed to being turned into a list of files and directories as it would be when it's interpreted by the shell. The mv command doesn't know anything about the * character being special.
If you want to have those shell interpretations, you need to execute the command through a shell. One example is like so, but a) you'll want to read up on the methods in exec() that take arrays of String, and b) you'll want to read up on ProcessBuilder, and c) you'll need to check your shell's man pages to see the exact syntax and arguments.
runtime.exec("/bin/bash -c 'mv x/* y'");

Dos command in java

Hi
I have used google to get an answer for this.
This is the command i have used to run some dos commands in java
Unfortunately it doesn't throws any exceptions but still the directory and the file news.txt is not created.
Process t=objrun.exec("command.com /c dir > c:/news.txt");
Process p=objrun.exec("command.com /c mkdir c:/Prabhath");
Please help me....am using windows xp OS.

Note that the java.util.File has the following methods that might do the job :public File[] listFiles()
public boolean mkdirs()
public boolean createNewFile()

Clearing the DOS Window in Java

hi
I want to clear the dos screen using java.
I saw 2 solutions on the net(given below) , but both did not work. Can someone advise how I can go about doing this ? I'm
working on Windows2000.
Thanks in advance.
Seema
1. char esc = 27; // ESC code
String clear = esc + "[2J" // note case
System.out.print(clear); // Dos screen should be cleared
2. Runtime.getRuntime().exec( "cmd.exe /c cls" ) ;

The escape code approach would only work on DOS windows that are processing ANSI escape sequences. This is something people used to enable all the time back in the pre-Windows days, since it was the only way to do things like clearing screens, setting colours, drawing menus out of text characters, etc. Ansi.sys still exists, at least on Win98 (not sure about NT, 2000, etc.). If you troll through the Microsoft web site or hunt down old books on DOS, you'll be able to find out how to set it up and use it.
