Sep 8, 2014how to put a console on a JFrame or on graphics window. I thought about simply using a JtextField however I don't have access to the readline command since it appears to me that it is only found in a Console Program. So basically I was wondering how to put up a console on JFrame so I can issue commands on it and watch graphical stuff happen on the same screen(minus where the console box is of course).

Command Line And Two Arguments
Sep 14, 2014 i have to run my program from the command line...My code is:
public static void main( String[] args )
{
// check command-line arguments
if ( args.length == 2 )
{
// get command-line arguments
String databaseUserName = args[ 0 ];
String databasePassword = args[ 1 ];
[code]....
Now everything works in Netbeans but running it from the command line, i get an error message ".java uses unchecked and unsafe operations".I have added a bit more code to the code above
for (int i = 0; i < args.length; i++) {
System.out.println("args[" + i + "]: "
+ args[i]);
}
Just not sure how to run it from the command line,
Command Line Program
Feb 8, 2014I have a program that runs in the terminal (I use Ubuntu). It asks the user for a String, does something with it, and terminates.It works in the NetBeans terminal, but not outside of it. Specifically, regardless of what I input, it doesn't continue with the program. I enter something, press enter and it just goes to the next line in the terminal.
Java Code:
Scanner scan=new Scanner(System.in);
System.out.println("Enter the music directory:");
String path=scan.nextLine(); mh_sh_highlight_all('java');
how do I pass in arguments when I run the program (still in Linux)? Is there a way to check if the program was launched from the terminal or not?

Cannot Run Java Program That Is Using External Library From Command Line
Mar 30, 2015I am reading the excellent book Algorithms. The author of this book is using his own libraries.
I have downloaded the libraries (it is a file called stdlib.jar) and I've store it in a directory called ~/Downloads(I am using a macbook pro).
Then I have created a project with IntelliJ Idea 14.1 using the default package (as it is the only way for a program to 'see' these libraries).
The program is running inside the ide, but because of the nature of this book, all the included code must be run from the command line.
The problem is that I cannot run for example the Average class from the command line because the system asks for the external library.
Specifically the error is :
I enter : java -cp . Average
and the Error I get is :
Exception in thread "main" java.lang.NoClassDefFoundError: StdIn
at Average.main(Average.java:11)
Caused by: java.lang.ClassNotFoundException: StdIn
at java.net.URLClassLoader$1.run(URLClassLoader.java:372)

The Average class is the following :
public class Average {
public static void main(String[] args) {
//Average the numbers on StdIn
double sum = 0.0;
int cnt = 0;

JSF :: Building Web Frontend For Command-Line-Based Software
Jun 17, 2014The goal of this software is to provide a web interface which must be able to manage the Quagga routing daemon. For those who don't know Quagga, the only interface it provides the user is its built-in cli. My project must convert web events to commands and vice-versa. how I'm going to maintain quagga's configuration state synchronized with JSF's managed beans. The example below shows the commands one must run on quagga's cli in order to add a BGP neighbor:
neighbor 10.0.0.1 remote-as 65535
neighbor 10.0.0.1 description "Just a Test"
neighbor 10.0.0.1 next-hop-self
neighbor 10.0.0.1 soft-reconfiguration inbound
write memory
In order to represent this piece of information in my project, I was thinking about mapping this to a class:
public class BGPNeighbor {
private String ip_address;
private Integer asn;
private Boolean next_hop_self;
private Boolean inbound_soft_reconfiguration;
}
With this I would parse the information from Quagga's configuration and map this to classes in my software. I think it's a lot easier to do with database-based software, the problem with this project is that it's not completely database oriented. The information must be fetched from the network, parsed, converted to classes and then they would be available to JSF as managed beans. Any alteration to this classes must be converted to quagga cli commands which must be executed through the network again (telnet).
