How to give command line arguments

does anyone help me out in how to give command line arguments after run my program
m using netbeans6.0.1

If you want your program to take console input while it's running (as opposed to command line arguments, which are passed once, when you start your program), you can wrap a BufferdInputStream or a Scanner around System.in.

Jay,
Your question isn't very clear, hence Joerg's well meaning but irrelevant advise.
Do you mean:
I've written a simple program in java which echos
it's command-line arguments to back to the console.
Here's my code:
package forums;
public class ArgsEchoer
public static void main(String[] args) {
for (String arg : args) {
System.out.println(arg);
But can't figure out how to compile and run the program.
I'm using winblows shista, and it's cr@p.
Please help me, Thanks in advance.So... where are you at? Have you installed the JDK (java development kit)? Which version? Is your path set? Is your classpath set?

How to add command line arguments to shortcuts in the LV8.5.1 installer

I want to create multiple shortcuts to my LV program, each with different command line arguments.
I can do this manually.
I want the installer to generate these shortcuts.
I can add different shortcuts in de installer build specification, but I cannot add commandline arguments in the shortcuts.
Does anyone know how to do this?
Rindert

Hello Forum,
Does anyone have any better data for this? I would also like to create an installer using Labview Project Explorer tool (Build Specification->Installer), and I have a need to create some shortcuts to some EXE's (VS.NET built, not LV) which need to have some arguments passed. I just verified that LV8.6 still does not seem to offer the option of passing arguments when creating shortcuts. Is this correct? Creating stub EXE's or batch files isn't a good option for my project, so I'd like to have someone confirm if LV installer tool can't create shortcuts w/ arguments before I fire up InstallShield.
Regards!

How to Pass Command line arguments to an exe created in LV8.0

Hi Friends,
I have Created an exe in LV8.0, which accepts the Folder path as input and executes.
I want to call this exe passing the parameter (i.e folder path in my case) from the command line argument. How to pass arguments to the exe ?
Generally we may be having different types of input parameters to a vi like numeric control, string, boolean etc..If we create an exe that needs three input parameters among which one is boolean, other is string and third is a numeric value.
How to pass these different types of input controls to the exe as parameters in command line at the same time?
Thanks and Regards,
SODLB

I don't have any experience with the 8.x application builder, but the 7.x one has a checkbox for passing the arguments to the executable.
As for reading them, there should be an example in the example finder (Help>>Find Examples) which shows how to do this. If you want to pass multiple parameters, I suggest you use a structure similar to NAME=VALUE, so that you can parse each element to find the = and then use a case structure to decide what to do with the parameters. This allows your users to enter or not enter any of the switches.

How to pass command line arguments to Web Start appclient?

Hi,
I would like to pass arguments to appclient, but "javaws" unable to do that.
Do I have to overwrite the JNLP? I use Sun Appserver 9.0, it creates JNLP on the fly!!!
Please help, thanx!
MB

Hi, MB.
If you are talking about the automatic Java Web Start support for launching app clients in GlassFish, you can pass the equivalent of command line arguments using the query string of the URL you use to launch the app client.
Briefly, use
http://host:port/client-path?arg=first-arg&arg=second-arg& ...
specifying the argument values in the order that you want them passed to the client.
The GlassFish server will do the right thing and generates the correct JNLP so your arguments are passed to the app client.
The GlassFish developer's guide http://glassfish.dev.java.net/nonav/javaee5/docs/AS91DG.pdf discusses this and all aspects of the Java Web Start support. You can also take a look at this blog entry http://blogs.sun.com/quinn/entry/command_line_arguments_and_properties that focuses on how to pass arguments.
Since this technique deals with argument passing in the URL, it works no matter how you launch the app client: a URL in a browser, the javaws command, etc.

How to count Command-Line Arguments ?

How do you count Command-Line Arguments ?
For example,
java program argument1 arguement2
I would like to be able to count how many arguements the user inputed
It should result as 2 for the bold line above
Thank you for your help

public static void main(String[] args) {
int numArgs = args.length; // args holds argument1 and argument2
}

How to pass command line arguments to JWS app

Hi,
I want to pass command line arguments to my JWS application. However those arguments are dynamic (eg the username of the user who launched the app) and thus I can not use the argument tag of JNLP file. So what do I need to do in this case?
Thanks.

Well, if it's the username on your server systems you should probably include it in the jnlp: can pass it in the url, write once and remove jnlp href attribute, etc.., etc.. (a quick tour of this forum should suffice).
If it's the OS username you should be able to retrieve it through system properties.
Whatever it is, passing dynamic arguments means launching javaws through a shell or a shell script (bat if running on windows), so you won't be able to launch through autogenerated desktop and menu shortcuts.
Anyway, you have two solutions:
Clean one: associate an extension to your app and write those infos in a file named after that extension.
Dirty one (always seen it work, but there's no warranty): javaws -open whateverParamYouLike yourAppURL.jnlp, will pass to your main method '-open' as args[0] and '+whateverParamYouLike+' as args[1]. I gotta admin I used it, but I had the most peculiar reason (my app needed another instance on a different JRE aware of being a secondary instance at startup time).
Bye.
PS: I'd really love dukes ;-)

Ant: how to get command-line argument?

When using Ant to build Java source files, what is the syntax of obtaining command-line argument in build.xml?

From the documentation:
http://ant.apache.org/manual/running.html#libs
Examples
ant
runs Ant using the build.xml file in the current directory, on the default target.
ant -buildfile test.xml
runs Ant using the test.xml file in the current directory, on the default target.
ant -buildfile test.xml dist
runs Ant using the test.xml file in the current directory, on the target called dist.
ant -buildfile test.xml -Dbuild=build/classes dist
runs Ant using the test.xml file in the current directory, on the target called dist, setting the build property to the value build/classes.
ant -lib /home/ant/extras
runs Ant picking up additional task and support jars from the /home/ant/extras location
steps:
- You define a property (like ${my.prop}) in your build.xml
- You define it in the command line, like
ant -Dmy.prop=chosen_value compile
where "compile" is the target and "-Dmy.prop=chosen_value" defines the value of the property "my.prop" as "chosen_value".

How to validate command line arguments

Hi good programmer.Can anyone help me with this problem.I want want to control my program which accept values from command line,in such a way that when I run it without entering arguments in the command line, it must display message that i must pass argument from command line instead of display the runtime error.
please help...
victor

Then you can check that you have the right number of args and print out a message and exit if you don't
e.g.
if (args.length != 2)
System.out.println("This program needs two arguments");
return;

How do SQR command line arguments work?

Hello,
I am using sqrw version 8.52. I would like to run SQR's for testing purposes from the command line with no user intervention. I found documentation that says I can do something like this:
"C:\Program Files (x86)\PT85206\bin\sqr\ora\BINW\sqrw" nint268.sqr USERNAME/PASSWORD@DATABASE PARAM1 PARAM2 PARAM3 "-zifC:\users\kramej3\pssqr.ini" "-iC:\Program Files\PT85206\bin\sqr\;C:\temp\sqr_run\;"
...where PARAMx is a parameter that is passed to the INPUT statements in the SQR (first PARAM to first INPUT, second to second, etc.) Unfortunately, it doesn't seem to want to work this way - the parameters are not passed to the program. Am I doing this right?
Alternately: is there a version of sqrw that runs as a console application and does not spawn another window to do so? If I could have sqrw run as a console application, I could get around the parameter requirement by spawning sqrw.exe via a Python script and then attaching to the stdin and stdout file handles.
Thanks!
-JK

See peoplebooks on this subject.
I believe it is flags before arguments

How to pass a command line argument to a jsp file...

Hi guys,
I'm writing a jsp file in which I have some java codes. I want to pass some command line arguments to that jsp file. In other words, I have some files located somewhere on my C drive and I want to pass the path to these files to my jsp file. How can it be done? I have never done before.
Any suggestion will be very hepful...
Thanks....

I dont know if I truly understand your problem...
For instance, when you place the url of your jsp you can add, at the end some parameters. For example:
http://myserver/myapp/myjsp.jsp?MyParameter=C:\Temp\JavaTutorial.html
In your JSP, you can place this code on a scriplet to get the value:
String path = request.getParameter("MyParameter");
Hope it helps.

Filenames as Command Line Arguments: How?

i need to create a program that involves taking in a file name as command line argument, reads the file and then displays its contents on the screen. it needs to work with any file with a .txt extension.
The only thing i dont fully understand is how to read the file name as a command line argument e.g.
"java FileReaderApp myfile.txt
----contents of file--------
Thanks in advance
Carl
P.S. I have lready read the various helps, utils etc for java and still dont really understand

Okay, first, it will help if you don't think of "filenames as command line args." The two concepts are totally independent.
Command line args are Strings. What you do with those Strings is up to you. Processing the command line args is the same, regardless of whether they represent file names or the turnons of the last 50 playmates.
The args array below contains the command line args.
public static void main(String[] args) {
// do stuff
} Files are generally referred to using the java.io.File. It takes a String for the file name. It doesn't matter where the String comes from.
Look at FileReader and BufferedReader to actually read the contents of the file.

How to read -Dname=value pair command line arguments

Hi
iam running one program called report.java as given below
compile:
javac report.java
run:
java report -Djava.path=home/arao/jaava1.5/bin
my problem is how to read name and value pair given in command line argument.
System.getProperty("java.path");//not working can anybody help how to read name and value
pair of -D option

If you put that string after the name of the class you are running, then it's a command line parameter. Your main() method can look at args[0] to see it. However it would be better if you just put it before the name of the class, where it's supposed to go if you want it to be treated as a system property.
