I have a dos command which starts an application. I want to start the application as an administrator. How can i do so? Below is the code which i tried.
String arg[]={"C:\\app1.exe", "C:\\app2.exe", "c:\\app3.exe"};
String pwd[]={"123","-x","-sf"};
String outputfile="c:\\output.xml"
String command=arg[0]+pwd[0]+arg[1]+pwd[1]+arg[2]+pwd[3]+output;
Process pr=rt.exec(command);
I tried the same command from command prompt and its working fine. But when i try to run the same from java code, it keeps on running without producing any output.
see runas -command:

I'm new to Java. I already installed Java, JDK and added it to Path, but when I try to run a command (like "java -version") it just flashes a CMD but doesn't show what I want to see. This happens with every command and doesn't even let me run Java code using an IDE. There is no error message, just a CMD flashing every time I try to run something (it also happens when double click the files like "java", "javac", etc).
How do you run these commands? Try running them from an interactive terminal window. Open it by typing windows key + R and then cmd. Then cd into your directory and type your commands there. Alternatively, if your commands are in a .bat file … you may add a pause command at the end.
This is entirely expected as java -version immediately exits after printing the version. This means that if you didn't start it from cmd, PowerShell, or another interactive shell, it opens a window which disappears immediately because the program ended in a fraction of a second.
Start cmd (Command Prompt) or PowerShell (either directly or through Windows Terminal), and run your commands in that interactive shell.
I am trying to execute cmd commands inside a java program using the following code
String command = "clingo F:\\clingo\\food1.lp F:\\clingo\\fooddata.txt"
+ " 0"+" >>F:\\clingo\\foodout.txt";
Process p1 = Runtime.getRuntime().exec(command);
This is executing in java without any exceptions, but the actual command is not running. If the command is run it should create text file foodout.txt in the location mentioned. Nothing is happening.
The actual command is
clingo food1.lp fooddata.txt 0 >>foodout.txt
clingo is a windows executable program. This command works fine when run in command prompt. I want to run this inside java program from click of a button. I have set environment variable for clingo. Clingo and this java project are in the same directory.
Before this i tried below code
String[] command = {"clingo", "food1.lp","fooddata.txt", "0", ">>foodout.txt"};
ProcessBuilder builder = new ProcessBuilder(command);
builder.directory(new File(WorkingDirectoryArea.getText()));
Process process = builder.start();
where Workingdirectoryarea contains the directory location for commands to be run. This code does nothing.
Can someone guide me or provide code sample on how to run the cmd command inside this java program. I am using Netbeans IDE. Thanks.
you said your command works with a command prompt. OK. If you look closely, the command window has a path entry (cmd= echo %PATH%). That's the difference between executing a command in a command window and executing a java process. You have 2 options.
1. Add the path to the process.
2. Add the path to the clingo command (i.e. "f:\path\clingo.exe ...)
Item 1 is especially needed when using dos commands. To add a path environment:
Runtime.getRuntime().exec not finding file in java environment
You are redirecting standard output to a file. This is not part of the command nor a command line parameter. Is the command interpreter that handles this.
You must invoke the command interpreter to run your program like this:
String command = "cmd /c clingo F:\\clingo\\food1.lp F:\\clingo\\fooddata.txt"
+ " 0"+" >>F:\\clingo\\foodout.txt";
Process p1 = Runtime.getRuntime().exec(command);
Note the cmd /cpart which invokes the command interpreter to run your command like you would do on a Windows terminal.
On Linux it would be sh -c or whatever shell you like.
EDIT 1
When running the command, clingo.exe must be in your path or it must be in the default directory for the Java interpreter. If not, you should give the full path to the executable, like this:
String command = "cmd /c F:\\clingo\\clingo F:\\clingo\\food1.lp F:\\clingo\\fooddata.txt"
+ " 0"+" >>F:\\clingo\\foodout.txt";
Try to run
F:\\clingo\\clingo F:\\clingo\\food1.lp F:\\clingo\\fooddata.txt 0 >> F:\\clingo\\foodout.txt
at a Windows prompt and see if it works as expected. If it works it also should work when run from a Java program. Please, replace the clingo path with the right one for your environment.
Your command must be like this: java -jar yourExecuteable.jar yourParameter
In your case: java -jar clingo.jar food1.lp fooddata.txt 0 >>foodout.txt
I'm trying to run a jar file using a bat command with jenkins. and I want to popup the cmd and execute the jar file. but the problem is jenkins execute commands inside its console. Then i inserted "start" command and hoped it'll work coz it creates a separate cmd to run the jar.
here is my bat code
start "window_name" java -jar myjarfile.jar
but when i executing using it jenkins it doesn't create a separate cmd window but it executes the jar file anyhow. it shows this line,
C:\Update>start "window_name" java -jar myjarfile.jar
any idea how to solve this? I want to pop up a black window when executing.
The trick is figuring out in what session you want to start the cmd.exe. On a remote server (which is most often the case with Jenkins), it's not necessary straight forward. Your Remote Desktop Session is not in the same session as someone who is logged in physically at the console.
Bring up Windows Task Manager
Click the Users tab
Note down the ID of the session of the logged in user that you want
Download psexec from Windows Sysinternals
Edited from here downwards
Open elevated command prompt: type cmd into Start's quicksearch, right click cmd.exe, select Run as Administrator.
Type C:\path\to\psexec.exe -accepteula and press enter.
Type C:\path\to\psexec.exe -i 1 cmd and press enter. (If you see a command prompt appear, all is good, close it now)
In Job configuration, configure Execute Windows Batch command step
Write the following:
C:\path\to\psexec.exe -accepteula && C:\path\to\psexec.exe -i 1 cmd /c start C:\full\path\to\java.exe -jar myjarfile.jar
A more detailed explanation is provided in this answer Open Excel on Jenkins CI
Thanks Guys, May be your solutions too will do the trick. Finally what I did is i created a socket program and executed server myself. Then scheduled jenkins to execute the client.(Server in my environment & client in jenkin's environment) When client connects to the server it executes the bat file. Now everything works fine.
The Java code runs the command prompt and passes parameters to it, and then executes. it works fine in Eclipse IDE, but when I make it as a service (in Windows 7) and run it, it doesn't work. What I want to ask is will this service invoke the command prompt, pass parameters, and run it. Just for reference on line code is given below.
String status = WMI.execute(new String[] {"cmd.exe", "/C", "cscript.exe", vbScriptFilePath, ipAddress, username, password, service}).split(WMI.CRLF)[0];
This is windows 7. It may have user access control enabled.(why not?).
In that case starting service is only done with process with administrative permissions. The user being administrator is not enough. See this question/answer and comments
Run java application as windows service (using jsl) - get error when installing
I tried open a command prompt using java program, how to execute the some exe file in this command prompt using java code.
Runtime.getRuntime().exec() or using ProcessBuilder.
Now, if you want to open command prompt on windows run pass "cmd.exe" to exec() method. You have to find which command to run for each other OS your application is targeted for.
