For example, I have someFile.jar. I can run it simply using java -jar someFile.jar.
But I want to create some files (for example .deb file) to install this jar to another machine. This machine may not have jre15 which is required for running this jar. So I want to create some executable file that will contain jar and JVM
I tried to use jpackage --name testName --input . --main-jar someFile.jar --linux-shortcut. This command generates `.deb file but it won't create terminal command testName (to run this jar) but it creates a desktop app that I can run as an application but no one terminal command created. So, how can I create a deb file from the jar with embedded JVM to be able to run it as a command from terminal?
Investigate the content of the deb, or investigate the filesystem once the package is installed. Per default you should find it in /opt/. Underneath that you find a bin directory with only one file. That is the one you can invoke from command line.
JPackage also creates a launcher, which resides in /opt//lib/*.desktop. Check that text and you see that the executable is just the file in the bin directory, which means the GUI will run that exact command when the icon is clicked.
Summary:- I need lots of dynamic data for my performance testing and it's not possible to generate those test data from Jmeter itself. Hence, I wrote a Java code which will generate these dynamic test data and will put those data into the excel file. This excel file can be consumed by JMeter script for the performance testing. Every iteration in JMeter needs a new set of test data and that's why I have created a bat file which will trigger the Maven execution(it's just mvn clean test) and will generate the fresh set of test data before each of iteration. Everything is working fine till this point. I just need to run the bat file from JMeter to trigger the test data creation before each iteration and that's the problem which I am facing
Problem:- As mentioned in the link How to run batch file(.bat) from Jmeter and as suggested by user #Dmitry T, I have added the OS sampler with the given parameters(See the screenshot below) but it is not starting the Maven execution. It is hitting the bat file(I put some msg command to check) but somehow it is not starting the execution. I tried the other solution given by the same user about using the Beanshell Sampler and running the command
Runtime.getRuntime().exec("C:/Windows/System32/cmd.exe /c D:/XXXX/XXX/XXXX/GenerateTestData.bat");
This is also not working. Am I missing something here? Please let me know if there is any solution for this? Appreciate any help on this?
The batch file is most likely not designed to work properly with current directory on execution being different to the directory containing the batch file. The current directory can be any directory. Very common are the directories %SystemRoot% (Windows directory) and %SystemRoot%\System32 or %SystemRoot%\SysWOW64 (Windows system directory) as current directory, whereby any directory can be the current directory on running a batch file.
A batch file referencing other files or directories relative to the batch file directory should set the current directory to the batch file directory or reference all directories and files with full batch file path.
The argument 0 of a batch file is always the batch file itself. The help output on running in command prompt window call /? explains how to reference an argument with a modifier. In this case %~dp0 should be used to get full path of the batch file.
So in the batch file can be used at top:
#echo off
cd /D "%~dp0"
The current directory is set with second command line to the directory containing the batch file as long as the batch file is stored on a drive with a drive letter.
There is another method to make the directory of the batch file the current directory which works even with batch file being stored on a network resource and the batch file is executed using its UNC path.
#echo off
setlocal EnableExtensions DisableDelayedExpansion
pushd "%~dp0" || exit /B
rem Other commands accessing files and directories in batch file directory
rem using no path or a path relative to current working directory.
popd
endlocal
The help output on running in a command prompt window pushd /? describes why this code works even with a UNC path on command extensions enabled which is made sure by the second command line which defines together with first command line completely the execution environment for the batch file without depending on configurations outside of the batch file.
Another solution is referencing all files and directories in batch file directory with full path which means with using %~dp0, for example "%~dp0ExcelFile.xlsx".
Note: The path string referenced with %~dp0 always ends with a backslash which is the directory separator on Windows as explained by Microsoft documentation about Naming Files, Paths, and Namespaces. Therefore concatenation of %~dp0 with another string like file/folder name or wildcard pattern should be done always without using an additional backslash for a 100% correct full file/folder/pattern argument string.
In the Command input provide full path to the cmd.exe
Change the Working directory to where your batch file lives
Use just batch file name in the Command Parameters
Something like:
See How to Run External Commands and Programs Locally and Remotely from JMeter article for more details.
Alternatively you can use Maven Exec Plugin to run your custom command before running the JMeter test
IS there any way to start a blank console in Windows platform ?
I'm writing a CLI where i want to open a separate window where user can log in and write their own command. When executing with cmd /c start command, it starts windows standard console.
Is there any other command ???
Assuming you're trying to start a java jar file, use a command like this:
start /d "%~dp0" java -jar "%~dp0\fpa.jar"
%~dp0 expands to the drive letter and path in which the batch file is located. Use that if you want to want to make sure that the PWD when running is the same location as the batch file. Otherwise, juse use
start java -jar "%~dp0\fpa.jar"
This will make sure that the batch file works even if you run it when not in the same directory as the jar file, as long as the jar file is in the same directory as the batch file.
You may need to make sure that java is in your path by having a line like
set path=jre6\bin;%PATH%
Also, you can eliminate the command line windows that comes up (for a GUI program by example) by using javaw instead of java.
You can use batch file in windows which would in turn start application that would accept user input. Something similar to this :
start cmd /c myapp.bat
I have a JAR file named helloworld.jar.
In order to run it, I'm executing the following command in a command-line window:
java -jar helloworld.jar
This works fine, but how do I execute it with double-click instead?
Do I need to install any software?
Easiest route is probably upgrading or re-installing the Java Runtime Environment (JRE).
Or this:
Open the Windows Explorer, from the Tools select 'Folder Options...'
Click the File Types tab, scroll down and select JAR File type.
Press the Advanced button.
In the Edit File Type dialog box, select open in Actions box and click Edit...
Press the Browse button and navigate to the location the Java interpreter javaw.exe.
In the Application used to perform action field, needs to display something similar to C:\Program Files\Java\j2re1.4.2_04\bin\javaw.exe" -jar "%1" % (Note: the part starting with 'javaw' must be exactly like that; the other part of the path name can vary depending on which version of Java you're using) then press the OK buttons until all the dialogs are closed.
Which was stolen from here: http://windowstipoftheday.blogspot.com/2005/10/setting-jar-file-association.html
In Windows Vista or Windows 7, the manual file association editor has been removed.
The easiest way is to run Jarfix, a tiny but powerful freeware tool. Just run it and your Java apps is back... double-clickable again.
If you need to distribute your .jar file and make it runnable at other people's Windows computers,
you can make a simple .bat file like this in the command prompt:
java -jar MyJavaTool.jar
and place the .bat file in the same directory as your .jar file.
If you have a jar file called Example.jar, follow these rules:
Open a notepad.exe
Write : java -jar Example.jar
Save it with the extension .bat
Copy it to the directory which has the .jar file
Double click it to run your .jar file
An interesting side effect of this causes a problem when starting runnable jar files in the command prompt.
If you try (in a command prompt):
jarfile.jar parameter
No joy, because this is being translated to the following (which doesn't work):
javaw.exe -jar jarfile.jar parameter
However, the following command does work:
java.exe -jar jarfile.jar parameter
If you change the association in file manager as described above to:
"C:\Program Files\Java\j2re1.4.2_04\bin\java.exe" -jar "%1" %*
Then you can type:
jarfile.jar parameter
in the command prompt and it will now work!
EDIT:(However you then get a black console window when you run a form based (non console) Java app, so this is not an ideal solution)
If you run these jar files by double clicking them in windows, no parameters will be passed so your Java code needs to handle the stack overflow exception and include a "press a key" function at the end or the window will just disappear.
In order to pass a parameter in windows you have to create a shortcut to the jar file, which includes the parameter in the target line (right click on the shortcut and select properties) you can not add parameters to the jar file icon itself in this way.
There isn't a single, consistent solution here, but you would have the same problem with any other console application.
There is a windows freeware application called "bat to exe" which you can use to create an exe file from a .bat file with the apropriate command line in it. you can also embed the jar file in the exe with this application, and make it clean it up when it has finished running, so this may be a more elegant solution.
First set path on cmd(command prompt):
set path="C:\Program Files\Java\jre6\bin"
then type
java -jar yourProgramname.jar
In Windows XP * you need just 2 shell commands:
C:\>ftype myjarfile="C:\JRE1.6\bin\javaw.exe" -jar "%1" %*
C:\>assoc .jar=myjarfile
obviously using the correct path for the JRE and any name you want instead of myjarfile.
To just check the current settings:
C:\>assoc .jar
C:\>ftype jarfile
this time using the value returned by the first command, if any, instead of jarfile.
* not tested with Windows 7
In regedit, open HKEY_CLASSES_ROOT\Applications\java.exe\shell\open\command
Double click on default on the left and add -jar between the java.exe path and the "%1" argument.
There is way without requiring user to do changes on his PC. Runtime.getRuntime.exec() allows us to start cmd.exe and execute commands inside of it. So, it's possible for java program to run itself in command prompt when user clicks .jar file.
public static void main(String[] args) throws IOException {
if(args.length == 0) {
Process p = Runtime.getRuntime().exec("cmd.exe /c start java -jar " + (new File(NameOfClass.class.getProtectionDomain().getCodeSource().getLocation().getPath())).getAbsolutePath() + " cmd");
} else {
//code to be executed
}
}
Besides all of the other suggestions, there is one other thing you need to consider. Is your helloworld.jar a console program? If it is, then I don't believe you'll be able to make it into a double-clickable jar file. Console programs use the regular cmd.exe shell window for their input and output. Usually the jar "launcher" is bound to javaw.exe which doesn't create a command-shell window.
I´m running Windows 7 x64 and was unable to use any of these fixes.
This one worked for me afterall:
http://thepanz.netsons.org/post/windows7-jar-file-association-broken-with-nokia-ovi
There is an archive which you can download containing a .bat file to run, but check the path of the actual javaw.exe!!!!
You want to check a couple of things; if this is your own jar file, make sure you have defined a Main-class in the manifest. Since we know you can run it from the command line, the other thing to do is create a windows shortcut, and modify the properties (you'll have to look around, I don't have a Windows machine to look at) so that the command it executes on open is the java -jar command you mentioned.
The other thing: if something isn't confused, it should work anyway; check and make sure you have java associated with the .jar extension.
Unfortunatelly, it is not so easy as Microsoft has removed advanced file association dialog in recent Windows editions. - With newer Windows versions you may only specify the application that is going to be used to open .jar file.
Fixing .jar file opening on Windows requires two steps.
Open the Control Panel, and chose "Default Programs -> Set Associations". Find .jar extension (Executable JAR file) there, and pick Java as default program to open this extension. It will probably be listed as "Java Platform(SE)". A faster alternative perhaps is straightforward right-click on a .jar file, and then change associated program by clicking on the "Change..." button.
Now open the regedit, and open the HKEY_CLASSES_ROOT\jarfile\shell\open\command key. Luckilly for us, we may specify parameters there for the (Default) value. On my Windows system it looks like: C:\app\32\jre7\bin\javaw.exe" -jar "%1" %* but in most cases it is the following string: C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*
NOTES:
Do not use java.exe there as it will open the shell window.
The jarfix tool mentioned in this thread most likely does nothing more than the registry modification for you. I prefer manual registry change method, as that implies that system administrator can "push" the registry change to all workstations in the network.
Create .bat file:
start javaw -jar %*
And choose app default to open .jar with this .bat file.
It will close cmd when start your .jar file.
Got the same problem, on Windows 10
The solution:
Check your JAVA_HOME and JAVA_PATH.
https://javatutorial.net/set-java-home-windows-10
Use Jarfix to restore the assiciation between .jar and javaw.exe
https://johann.loefflmann.net/en/software/jarfix/index.html
I had the same problem in Windows 10. I fixed it using righ-click on the "helloworld.jar" and go to properties and click on change button under "Opens with:" and select "Look for another app on this PC". In the "Open with..." dialog box, go to your Java folder location on your PC and open corresponding jdk folder and then open the bin folder and select "javaw.exe" from there. Then next time your "helloworld.jar" will open the normal way.
Usual java location example : "C:\Program Files (x86)\Java\jdk1.8.0_111\bin".
Another way to run jar files with a click/double-click, is to prepend "-jar " to the
file's name. For example, you would rename the file MyJar.jar to -jar MyJar.jar.
You must have the .class files associated with java.exe, of course. This might not work in all cases, but it has worked most times for me.
PreScript: If your prompt appears and disappears immediately, the reason it does so is that your program gets executed and auto shut. Try putting a scanner in the end to terminate and it'll keep your prompt waiting for input before terminating. (Or use delay maybe)
Was in the very same situation, where running .jar from cmd was working fine, but double clicking did nothing.
Solution:
Open any text editor and write the command line:
java -jar Example.jar
Save the file as a .bat file.
Run this bat file to get the needed output.
Taking it one step forward, you can convert this bat file to exe file using a simple GUI tool like Bat To Exe Converter.
Now you can share your .jar as a distribution in .exe file which anyone can use just make sure you keep all the files together. (Especially the .jar and .bat file cause .bat is only a cmd prompt)(How it feels logical)
I am fairly new to development and learning a lot. Please excuse for any mistakes if committed. Suggestions are welcome.
If you use eclipse for making your java files, you can choose to export it as a runnable jar file. I did this with my programs and I can just click on the jar and it will run just like that. This will work on both windows, as well as os x.
Making a start.bat was the only thing that worked for me.
open a text document and enter. java -jar whatever yours is called .jar
save as start.bat in the same folder as the .jar file you want to execute. and then run the. bat
If you need to run the jar file by double clicking on it, you have to create it as a "Runnable JAR". you can do it simply with your IDE.
If you're using eclipse, follow these steps :
To create a new runnable JAR file in the workbench:
1.From the menu bar's File menu, select Export.
2.Expand the Java node and select Runnable JAR file. Click Next.
3.In the Opens the Runnable JAR export wizard Runnable JAR File Specification page, select a 'Java Application' launch configuration to use to create a runnable JAR.
4.In the Export destination field, either type or click Browse to select a location for the JAR file.
5.Select an appropriate library handling strategy.
Optionally, you can also create an ANT script to quickly regenerate a previously created runnable JAR file.
more information can be found on Eclipse help Page: LINK
There are many methods for running .jar file on windows. One of them is using the command prompt.
Steps :
Open command prompt(Run as administrator)
Now write "cd\" command for root directory
Type "java jar filename.jar"
Note: you can also use any third party apps like WinRAR, jarfix, etc.
Steps:
1.) search for Java SE Runtime Environment on Google: https://www.google.com/search?q=Java+SE+Runtime+Environment
2.) install the appropriate version onto your computer
For compiling:
javac -cp ".;./mysql-connector-java-5.0.8.jar;mybatis-3.0.1.jar;ibatis-2.3.0.677.jar" MainStart.java
For running:
java -cp ".;./mysql-connector-java-5.0.8.jar;mybatis-3.0.1.jar;ibatis-2.3.0.677.jar" MainStart
use .bat file:
Put your command in a .bat file. here, your command will be java -jar path\yourJarName.jar.
Something like: java -jar C:\workspace\myApplication.jar
Save it and double click on bat file to run your jar.
Actually, I faced this problem too. I got around it by making a .bat runner for my jar file.
Here is the code:
class FileHandler{
public static File create_CMD_Rnner(){
int exitCode = -1625348952;
try{
File runner = new File(Main.batName);
PrintWriter printer = new PrintWriter(runner);
printer.println("#echo off");
printer.println("title " + Main.applicationTitle);
printer.println("java -jar " + Main.jarName + " " + Main.startCode );
printer.println("PAUSE");
printer.flush();
printer.close();
return runner;
}catch(Exception e){
System.err.println("Coudln't create a runner bat \n exit code: " + exitCode);
System.exit(exitCode);
return null;
}
}
}
Then in Your Main application class do this:
public class Main{
static String jarName = "application.jar";
static String applicationTitle = "java Application";
static String startCode = "javaIsTheBest";
static String batName = "_.bat";
public static void main(String args[]) throws Exception{
if(args.length == 0 || !args[0].equals(startCode)) {
Desktop.getDesktop().open(FilesHandler.create_CMD_Rnner());
System.exit(0);
}else{
//just in case you wanted to hide the bat
deleteRunner();
// Congratulations now you are running in a cmd window ... do whatever you want
//......
System.out.println("i Am Running in CMD");
//......
Thread.sleep(84600);
}
}
public static void deleteRunner(){
File batRunner = new File(batName);
if(batRunner.exists()) batRunner.delete();
}
}
Please Note that
this code (my code) works only with a jar file, not a class file.
the jar file must have the same name as the String "jarName" is the Main class
