Java Command Prompt Commands

This is a stoopid question and I've searched the forums, but what is the command in DOS prompt to view your classpath.
When I run java -classpath it gives me all the various options e.g.
java -cp -classpath
but non of these work? whats the craic?
M.

What do you mean by "none of these work"?
Suppose that you have a file HelloWorld.class in the directory C:\MyClasses. If you type:
java -classpath C:\MyClasses HelloWorld
it should run your program without problems.
Are you getting an error message? What's the error message?

Exceptio in thread "main" java.lang.NoClassDefFoundError
in thread main. The Teste.java file is compiled finely using

}So if you have any suggestion, please post it. Thanks!!

Soneca,
You're a complete idiot.
Along with crossposting every question you have you often respond like this in threads. Just a complete jacka$$.
I'll be sure to ignore you in future other than to point out your crossposts when I find them of course.
This previous thread of yours (cross posted as always [in 4 forums!!!]) really is demonstrative of the fundamental deepness of your nitwittery

How to run a command prompt " command " through java code

hi all,
There is a command
"java -jar selenium-server.jar -interactive"
which i am running through command prompt after going to D:\MyFolder\Examples .
i want to execute this command using java code .please help

This has already been answered in your other two threads on this topic - http://forum.java.sun.com/thread.jspa?threadID=5221221&messageID=9898287#9898287 and http://forum.java.sun.com/thread.jspa?threadID=5221223&messageID=9898290#9898290.
For some reason you don't want to read the reference that tells you exactly how to do what you want and how to avoid the pitfalls - http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html .

Runtime.exec() I need to run a command prompt command from java.

the code i have that doesn't seem to work is:
String driveloc = System.getProperty("user.dir").substring( 0, 1 );
        String path = jTextFieldPath.getText();
        String path2 = jTextFieldPath.getText().substring(0, jTextFieldPath.getText().length()-3) + "lst";
        String[] cmd = { "cmd.exe", "/" + driveloc, "ASMtools\\AS11 " + path + " -L >" + path2};
        txt_mf.append( cmd[3] );
        try {
            Process np = Runtime.getRuntime().exec( cmd );
        catch( java.io.IOException ioe) {
            //error
        }jTextFieldPath.getText() contains the path of the file saved by my program.
the line of code i am trying to run is:
AS11 FILE1 -L FILE2this line compiles the asm file and converts it to a lst creating an s19 file in the process. AS11 is an exe that aids the command prompt much like javac.
If you could help me figure this out it would be great.
Thanks in advance,
-Juke

String driveloc =
System.getProperty("user.dir").substring( 0, 1 );
String[] cmd = { "cmd.exe", "/" + driveloc,
"ASMtools\\AS11 " + path + " -L >" + path2};Are you sure you want to invoke cmd.exe with the switch /c or /d or whatever depending on System.getProperty("user.dir") ?
Starts a new instance of the Windows 2000 command interpreter
CMD [A | /U] [Q] [D] [E:ON | /E:OFF] [F:ON | /F:OFF] [V:ON | /V:OFF]
    [[S] [C | /K] string]
/C      Carries out the command specified by string and then terminates
/K      Carries out the command specified by string but remains
/S      Modifies the treatment of string after /C or /K (see below)
/Q      Turns echo off
/D      Disable execution of AutoRun commands from registry (see below)
/A      Causes the output of internal commands to a pipe or file to be ANSI
/U      Causes the output of internal commands to a pipe or file to be
        Unicode
/T:fg   Sets the foreground/background colors (see COLOR /? for more info)
/E:ON   Enable command extensions (see below)
/E:OFF Disable command extensions (see below)
/F:ON   Enable file and directory name completion characters (see below)
/F:OFF Disable file and directory name completion characters (see below)
/V:ON   Enable delayed environment variable expansion using c as the
        delimiter. For example, /V:ON would allow !var! to expand the
        variable var at execution time. The var syntax expands variables
        at input time, which is quite a different thing when inside of a FOR
        loop.
/V:OFF Disable delayed environment expansion.

Command Prompt commands

I know that while I use the command prompt in windows to execute java application, I cannot use the other windows commands such as
ipconfig,
telnet...
etc
Is there anyway where I can use the java commands (javac, java) AND the other regular commands??

The problem is happening because the PATH variable
settings is not proper.
Go to the environment variables in your machine and
append the following to the PATH environment
variable
%SystemRoot%\system32;%SystemRoot%;Save and then open a new command window and try.Yep, you were right.
I did that to the user's path and it worked after I appended it. It works for both now,
thanks.

Problem in executing command prompt commands through application

Hi,
I am facing issue in executing commands through VC++ application.
My application is a dialog based MFC application in VS2008.
I want to execute below commands programmatically.
devenv D:\TestApp\TestApp.sln /rebuild release
devenv D:\TestApp\TestApp.sln /rebuild debug
But I am not able to set the current directory path as "D:\TestApp\" programatically.
Through which API I can execute multiple commands on command prompt programmatically same as we do manually on cmd.
Please Help.
Thanks in Advance.
Thanks & Regards, Mayank Agarwal

Why can you "not able to set the current directory path as "D:\TestApp\" programatically"? Are you forgetting to escape the backslashes?
Why to you need to set the current directory anyway?
What is the problem with executing multiple commands?
As to your basic goal, have you looked at
system()
ShellExecute()
ShelExecuteEx()
CreateProcess()
? Perhaps you should show us what you have tried.

Running command prompt commands in java

I can use:
Process j = Runtime.getRuntime().exec("command";
BufferedReader stdInput = new BufferedReader(new InputStreamReader(j.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(j.getErrorStream()));
to run commands in the command line buf if i make another process..the command will not run...any ideas?

ProcessBuilder can simplify things:
redirectErrorStream
<quote>
If this property is true, then any error output generated by subprocesses subsequently started by this object's start() method will be merged with the standard output, so that both can be read using the Process.getInputStream() method. This makes it easier to correlate error messages with the corresponding output.

Manipulating Windows command prompt through Java

I am wondering if there is any way to manipulate simple Windows command prompt commands like color, cd, dir, cls through a java application. Any help or informative redirection would be much appreciated.

Reading states of usb-6501 kit from command prompt?

Hi all!
I have been planning to use USB-6501 kit as one part of my test bench.
There will be need of checking state of some relays on
tested unit.
I would like to connect 6501 to those relays and read those
states using bare command prompt commands like readDigPort.exe
1. What software in need to install minimum to use writeDigPort.exe or readDigPort.exe commands at command prompt??
Those commands should be included in python script.
2. Is there such Linux commands also included somewhere in installation media/net ?
I am Using Fedora 3 ( Comedi not supporting 6501 ?)
3. I need only easy way to set and read values from 6501 ports which are my possibilities to do it?
Thank you!

Hello,
Here are the answers:
1) You need NI-DAQmx Base driver for Linux. You may find the driver from web:
http://digital.ni.com/softlib.nsf/websearch/930D8687AD03A02C86256F8C00823BDB
Supported platforms and installation instructions can be found from here:
http://zone.ni.com/devzone/conceptd.nsf/webmain/42b73a7b82f0fec786256fb1007227ec
Please read the readme-file before installation.
2 & 3) LabVIEW and C-examples are shipped with the driver. C examples are installed by default to /usr/local/natinst/nidaqmxbase/examples. Use the example as a basic body for your application. NI-DAQmx Base Function reference help can be found from here:

Command prompt to see remote connections

are there any command prompt commands to see which remote servers my apps are connected to? specifically database servers.

You can use:
netstat -ano (this command will show you all connections established, listening, etc.)
or
netstat -ano | findstr /C:"1433" (this command will show you all connections using 1433 port for example).

Is it possible to run a java program without using the command prompt?

Hi,
I was wondering whether it is possible to run a Java program (not an applet) without using a command line in the command prompt?
Basically I want to run a program that will be continually running in the background and hence I don't want to have a command prompt screen loaded up as well - I just want the program to be running in the task bar.
I know how to run the program in the task bar - but I still need to launch the program from the command prompt - is there anyway I can get a program running without having to start it from the command prompt?
Cheers

Or create a desktop shortcut (in Windows) or an application launcher ( in Linux GUI).
