Using Java in windows command prompt

Hi,
I don't know if I have been searching correctly, but I haven't found a solution to my problem through common search engines.
I'm programming in java using vim (accessed through windows command prompt), and I've created classes, everything compiles fine.
However, I wanted to test my classes my creating instances of them (i.e. objects) through the same windows command line (command prompt). I know you can achieve this by using interaction panes through third party programs such as Dr.Java and eclipse, but I was wondering if this can be done using the command line.
Thanks
Jaime

Thanks Paulcw for your quick reply! :D
I'm guessing I didn't word my question properly.
Neither of my classes have a main method in them, so when I am trying to create instances (objects) of them, I would like to as if my command line was the main.
For example:
Class1 c = new Class1(parameters);
c.moveRight();
etc.
I'd like to be able to use my classes methods from the command line, I think what I'm looking for is a batch, but I'm not sure.
Thanks again,
Jaime

Java Code Compilation in Windows Command Prompt

Hi Everyone,
I have been programming in java for quite some time now using an IDE (eclipse). I downloaded the following java file from:
http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/JpegImagesToMovie.html#requirements
and have downloaded the required JMF. The problem is that I want to compile and run this code in Windows Command Prompt; however, I keep receiving errors upon compilation because I do not know how to make jmf.jar be recognized as a library.
Thx.

javac -cp jmf.jar;otherJars file1.java file2.java file3.java...
Run java and javac from the command line for an explanation of their options.

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.

How to execute a scenario from Windows command prompt

Hi,
I have a package which is executing fine from Designer. But the same scenario if I am trying to execute from windows command prompt, then it is giving error.
The package is getting a refresh variable, passing to interface which is creating a file from table, this file is then getting FTP'ed to another server.
I am executing following command -
startscen OB_TAB_TO_FILE_PKG 001 ODICTX "-v=2"
The error is -
A JDK is required to execute Web Services with OracleDI. You are currently using
a JRE.

Hi,
you need to make the necessary changes to the %odi%\bin\odiparams.bat config file, under the "Repository Connection Information" section so that startscen knows how to extract metadata from your repository.
You apparently have left the default settings to the Hypersonic demo repository. Is that the technology your repository is hosted on?

Running eclipse java project on command prompt

Hi all,
I have one simple java project and that is very well running in eclipse. I have added some external JARs to that project. It performs this job- it creates connection to server, and listens to the signals from server.
My question is - how do I run that java project on command prompt?*
I want to run that using ANT or simply I want to make a JAR file so I can execute JAR on command prompt. I created JAR, but it doesn't contain external jar which I added to the project. So I was not able to run that project.
Can you please tell me any of the method - using ANT or by making JAR?
Also can you be little bit more explanatory in reply?
Thanks

I want to make a JAR file so I can execute JAR on command prompt.This is very likely a good way to proceed. It is explained in great detail in Sun's Tutorial in the section on [Packaging Programs in JAR Files|http://java.sun.com/docs/books/tutorial/deployment/jar/index.html].
I created JAR, but it doesn't contain external jar which I added to the project. So I was not able to run that project.Yes - the jar file you create has to know about the classes and other resources in that external jar. Otherwise, at runtime, the program will not be able to get at the stuff it needs. Usually you don't include that other jar (or its contents) in the jar file you are creating. Instead you provide your jar file with a manifest that describes the other jar's location. Details are also in the tutorial.
One thing to note is that Sun's tutorial provides a lot of explanatory, conceptual, material. To that end it keeps the context simple and transparent by describing the steps as they would be carried out by someone working at the command line. The Eclipse documentation and forums might provide a more click-this-drag-that "explanation". If you do follow the method in the Tutorial and get stuck, post a description of the actual commands you used and their outcome.

TDMS Defragment-Through Windows Command Prompt

Dear All,
we need to Defragment the TDMS file by TDMS Defragment.VI via Windows Command Prompt.
Work flow will be as below
1.An Application wil be created to defragment using TDMS Defragment.VI
2. When user stop Main Application (App 1) which records data for long time in tdms ,the Main application (App 1) will call defragmenting Application (App 2) via cmd and should get the file path and start defragmentation and it should pop a message defragmentation completed. and dont want Main Application (App 1) to do anything apart from triggering tdms defragmentation.
Reason is We dont want the Main Application (App 1) to wait for Long time till defragmentation and Since we need to use the Main Application (App 1) for other testing.
So we decided to do this defragmentationin in some other way and display the completion message to user
please provide suggestions

I'd also recommend doing this in one application. If you truely want to do it from a command line you can. LabVIEW built EXEs can support command line switches if you enable it in the build specificaitons. If you do this you'll probably want to support multiple instances, and code it so that it will exit once the conversion is done. But again you can get more information from the result of the defrag (like error) if you do it in the same application.

How java runs in command prompt and why java runs on it

how java runs in command prompt and why java runs on it

command prompt was used before the development of IDEs like RAD,eclipse etc.
its still used for better understanding of the compilation and errors.
type the java file and save the file(source file) in the bin folder of ur jdk environment with extension .java. the source file must be the one that has the main method declared.
in the cmd prompt screen , set the path of bin folder.
eg:C:/program files/jdk(some version)/bin/...
for compilation,type:
javac (source file_name).java and press enter
for running the file:
java source file_name

Log ConsoleHandler + Windows Command Prompt

Having really strange problem:
Program started from Windows Command Prompt.
Logging with ConsoleHandler.
If select something with "Edit->Mark" in this Command Prompt, process stop responding.
Has anybody seen such behavior?

Correction:
Looks like anything writing to stdout/stderr hangs in Windows Command Prompt "mark" mode.
Could not find anything about how it works.

How to get no. of rows of Windows Command Prompt in java

hi all,
can anybody tell me that is there any java utility avalilable throght I can find the how many rows avalilbe on currently executing command prompt, and also how can i clear the content of command prompt (result of 'cls' command).
Currently execting command prompt means from where I have run my java program.
any reference is also welcome.
thanks in advance.

Clearing the screen is trivial, as long as you're OK with making your program specific to Windows only (i.e. you never hope to run it on any other OS ever):
Runtime.getRuntime().exec("cmd /c cls");As to figuring out how many lines your command window's screen buffer has - good luck with that. I'm not familiar enough with the Win32 API to get this info, but you'll have to figure out what that is, and call it via JNI.

I'm happy to clarify more if necessary.
Can anyone help with this?

Bill,
Thank you for the quick answer. I believe you are right in your assumption.
I have been searching but found nothing so far.
I need to be able to run this line "wmic
Product where name='XXX XXX XXX' call uninstall"
in an elevated command prompt to uninstall the program.
I was looking for a VB script or PowerShell to execute it remotely on non domain roaming PCs.
Th3e command can be run remotely against stand-alone workstations but you must supply credentials. Post in the platform forum for you version of Windows for help in using the WMIC utility. WMIC /? will give you all of the command options fro
remote execution. UAC only affects local systems. You cannot use WMIC to remote back to the local system. WMIC does not allow impersonation to the local system.
Most installers will not automatically allow an unattended uninstall. If there is any dialog at all the uninstall will fail and can hang.
I recommend contacting the vendor of the application to get more information.
In all cases you cannot bypass UAC as Bill has noted. I am only noting that, sometimes, in a workgroup, you can use WMIC to remotely uninstall an application.
¯\_(ツ)_/¯

Set Title of Windows Command Prompt Window

I'm running a text-only Java application in a Windows XP Command Prompt window. Is there a way for my application to change the title of the window as it runs?

GaryS wrote:

of cross platform similarities. you can always run your program using a batch file and
set the title in there.

"java.lang.UnsatisfiedLinkError" happen when I use java.exe in command line

When I use Eclipse 3.01 to run the program it has any problem.But If I use the command line "java -classpath D:\Java_prj\Java\NativeMethod\out com.bruce.nativemethod.HelloNative",a error message will appear below:

     at com.bruce.nativemethod.HelloNative.<clinit>(HelloNative.java:21)My HelloNative.dll and HelloNative.class has all been putted in D:\Java_prj\Java\NativeMethod\out\com\bruce\nativemethod.
My all source code is here:

public class HelloNative{
     public static native void greeting();
     //Load the library
     static {

#endif
#endifI thinked the code is not problem.But why I can't not run it use java.exe tool in command line?

Thanks everybody! My problem has been solved.The path "./out/com/bruce/nativemethod/HelloNative" is right because it can run in Eclipse 3.01.I don't agree use the absolute path.If do so,it may not use in another machine. The problem is when I use the "java -classpath D:\Java_prj\Java\NativeMethod com.bruce.nativemethod.HelloNative" in the command line windows,I have putted it the C:\ directory to excute.laterly,I putted the command in the D:\Java_prj\Java\NativeMethod,the result "Hello world!" is appear.

Javac command in windows command prompt

Hi, i would just like to know how i can enable the javac command in the command prompt of windows without being in the java/bin directory...i have tried env. variables and stuff but to no avail, however the java command work.
Thanks Rudy
ps does anyone know any good rmi tutorials which are easy to follow, thanks.

Err, nm, just reread that.
The environment Path is the way to go.
Just add the bin directory to the end of the PATH in the advanced option of my computer. You may need to reboot.
