I wrap my Java Swing application as an exe using Jsmooth but I can see no way to take advantage of Java 6 splash screen option. I have the following manifest file:
Manifest-Version: 1.0
SplashScreen-Image: resources/LOADLOGO.png
Main-Class: se.bookingapp.UI.MainFrame
The splash screen appears if I simply click on the jar file of the application. However, the JSmooth generated exe form of the jar file does not show the splash screen somehow. Does anyone know why?
Yesterday I've finished to develop my java application and I had the same issue. If I double click the .jar file or I execute in a command line splash screen works perfectly, but when I execute the wrapped file it doesn't. Seems just JSmooth doesn't support this feature.
However I made a little trick to have a wrapped .exe and splash screen working at the same time. I made a little application called ApplicationLoader.jar that consists in a single main class that execute java -jar "Application.jar" in a command line. Here is the complete code:
public class ApplicationLoader {
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
/* First I check if the first parameter is not null and it's not an empty string */
if(args[0] != null && !args[0].trim().isEmpty()){
/* Then I use java.util.regex package to validate the parameter is a .jar file */
Pattern pattern = Pattern.compile(".*jar");
Matcher matcher = pattern.matcher(args[0]);
if(matcher.matches()){
/* Finally I define the command line like: java -jar "Application.jar" */
String command = "java -jar \"" + args[0] + "\"";
try {
Runtime r = Runtime.getRuntime();
ProcessBuilder pb = new ProcessBuilder("cmd.exe", "/c", command);
Process p = pb.start();
p.waitFor();
} catch (IOException | InterruptedException ex) {
JOptionPane.showMessageDialog(null, ex.getMessage(), "Error executing: "+command, JOptionPane.ERROR_MESSAGE);
}
} else {
JOptionPane.showMessageDialog(null, "The argument is not a .jar file!!");
}
} else {
JOptionPane.showMessageDialog(null, "There's not a valid argument!");
}
}
}
I have this folder structure for my application:
MyApp
+-- bin
| +-- MyApp.jar
| +-- ApplicationLoader.jar
+-- MyApp.exe
So in JSmoot I changed the classpath to ApplicationLoader.jar and add the relative location to my application in Application Arguments section like this:
And that's it. I know this is not the best option but is a workaround.
However there's a little problem:
Since ApplicationLoader.jar calls a cmd.exe then the wrapped .exe and your application will execute in two different processes.
This implies that if you have to kill .exe process for some reason (unexpected crash or something), your java application still working as a java.exe process. So in that case you must kill MyApp.exe and java.exe processes. Actually if you just kill java.exe process then MyApp.exe process will finish execution by itself.
If you keep this in mind and you can live with that I think this option is quite simple and useful.
I hope this be helpful to anybody looking for a workaround to this issue.
Does it work when you execute the jar file? Open it with WinRar for example, and check if the manifest is into META-INF folder, and LOADLOGO.png is in the right folder too.
After doing that, it should work. It works for me. Nothing wrong in your manifest.

I would like to open TestComplete from java, but I can't do that, because lack of privilege. When I run my code
public static void StartTC() {
try{
Process p = Runtime.getRuntime().exec(new String[] {"C:\\Program Files (x86)\\SmartBear\\TestComplete 11\\Bin\\TestComplete.exe"});
}
catch (IOException e) {
e.printStackTrace();
}
}
the program exits with CreateProcess error=740, and tells me that I need higher privilege for this action.
I know that I could make a .lnk with admin priv. at open properties of the exe, but there could be a right way to do this.
I think you can use File class for setting permissions.
File file = new File("File.c");
//but file permission are OS specific.
file.setExecutable(true);
In linux it will work.
If you are using windows then you can run "icacls" command to give permission to the file.
C:\>icacls "D:\test" /grant John:(OI)(CI)F /T
This command can be used to to give permission in windows.
According do MS documentation:
F = Full Control
CI = Container Inherit - This flag indicates that subordinate containers will inherit this ACE.
OI = Object Inherit - This flag indicates that subordinate files will inherit the ACE.
/T = Apply recursively to existing files and sub-folders. (OI and CI only apply to new files and sub-folders). Credit: comment by #AlexSpence.
You can run above command using Runtime.getRuntime().exec("icacls something here");
I hope I helped you.
You need to disable the Tools | Options... | Engines | General | Enable support for testing Windows Store applications option in TestComplete.
Information on how this can affect working with TestComplete from an external application like in your case can be found in the Requirements for Testing Windows Store Applications help topic.
So I made an executable file with Eclipse but when I double-click it nothing happens. It IS NOT because I've got wrong association for running .jar files (I'm running okey my another jar program just by double-clicking it).
I also tried with command prompt and the console doesn't print anything at all and get back to be "normal".
I think it's something with main class so the thread doesn't last but closes after running (however it looks like the code isn't run because console would print lot of Slick stuff).
So here is the main method:
public static void main(String[] args) {
Shiftjumper shiftjumper = new Shiftjumper("Shiftjumper - behavior prototype");
try {
AppGameContainer gc = new AppGameContainer(shiftjumper);
gc.setDisplayMode(TILE_SIZE*RIGHT_LEFT_TILES, TILE_SIZE*UP_DOWN_TILES, false);
//gc.setTargetFrameRate(60);
gc.start();
} catch (SlickException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
And here the manifest:
Manifest-Version: 1.0
Rsrc-Class-Path: ./ lwjgl.jar slick.jar
Class-Path: .
Rsrc-Main-Class: engine.Shiftjumper
Main-Class: org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader
You need to download a tool known as JarSplice. JarSplice is a very simple GUI based application which packages all libraries and native code into the form of either a .JAR, a .EXE, a.SH or a .APP. Here is a link to the site: http://ninjacave.com/jarsplice
Hope this helps :)
Try running the jar in your terminal or command prompt, if there are any exceptions it will print to the console and you can debug
In my war, I have file exe in WEB-INF\classes\
How can I execute this file in Java code (How can I specify path to this file) ?
command = " ? ";
Process x = p.exec(command);
Te following approach could work:
1) Prepare full path of your executable:
ServletContext context = getContext();
String fullPath = context.getRealPath("/WEB-INF/classes/executable");
2) Execute like you would normally do it:
String[] cmd = { fullPath /*[...] arguments */};
Process p = Runtime.getRuntime().exec(cmd);
p.waitFor();
This is a simplified example; you may also want to read more about ProcessBuilder.
This is bad idea. Imagine simply fact that your .war packege should run on almost any server (".war is platform independend") and your .exe file is compiled just for one architecture.
Better should be execute your .exe as external program just for separate platform independent and platform dependent part. Then in java you can test operating system and on this basis run desired externel programm.
Read this link with similar question.
The best way to do find a file's real location inside a web app is to use the ServletContext.getRealPath (see http://docs.oracle.com/javaee/6/api/javax/servlet/ServletContext.html#getRealPath(java.lang.String))
You can access that object from the session...
I made a little program and it worked fine, but now. First, it mux the xml chapter file in the mkv file, so we get a muxed mkv file. Some day ago I updated java to 1.7.21 and I think this is the problem why it is not working now. It's a little strange, but when I run in netbeans everything is fine, but when I build and I run the .jar file, it is not working. It create the xml file, but not mux in the mkv file (and because not muxed not delete the xml file). Here is the code: (filename=xml file path; mkv=mkv file path)
public void muxing() {
try {
Runtime rt = Runtime.getRuntime();
Process p = rt.exec("c:\\Program Files\\MKVtoolnix\\mkvpropedit.exe --chapters \""+filename+"\" \""+mkv+"\"");
if (p.waitFor()==0) {
File xmlfile=new File(filename);
xmlfile.delete();
}
}
catch(Exception e) {
System.out.println(e.getMessage());
}
}
The program worked with java 1.6 and I think with 1.7.17 too. Win7 32bit. Sorry for my bad English.
Oracle has made breaking changes to Runtime.exec() in Java 7 update 21 (and 6 update 45).
If the program name contains spaces, you need to specify command and arguments in an array:
Process p = Runtime.getRuntime().exec(new String[] {
"C:\\Program Files\\MKVtoolnix\\mkvpropedit.exe",
"--chapters", "\""+filename+"\"", "\""+mkv+"\""});
Another option is to use java.lang.ProcessBuilder:
Process p = new ProcessBuilder("C:\\Program Files\\MKVtoolnix\\mkvpropedit.exe",
"--chapters", "\""+filename+"\"", "\""+mkv+"\"").start();
As stated by Oracle:
Applications that need to launch programs with spaces in the program name should consider using the variants of Runtime.exec that allow the command and arguments to be specified in an array.
Alternatively, the preferred way to create operating systems processes since JDK 5.0 is using java.lang.ProcessBuilder. The ProcessBuilder class has a much more complete API for setting the environment, working directory and redirecting streams for the process.
here i'm trying to launch a java program inside another java program.
after some search in the forum i found some clues but my code launches only .exe file and not .java file why?
import java.io.*;
public class Mana
{
public static void main(String args[])
throws IOException, InterruptedException
{
try
{
Process p=Runtime.getRuntime().exec(" D:\\NetBeansProjects\\GetIPAddress\\dist\\GetIPAddress.jar");
}
catch(IOException e1) {System.out.println(e1);}
}
}
for java file you must run javaw.exe(not java, because java.exe shows new console window) from jre:
Process p=Runtime.getRuntime().exec("javaw -jar D:\\NetBeansProjects\\GetIPAddress\\dist\\GetIPAddress.jar");
If you are ok to use 3rd party library, you can use:
http://code.google.com/p/jlibs/wiki/JavaProcessBuilder
Okay, looks like you have several problems.
First, to call a java program as a jar file, you need to have the jar file. Your question first looked like you already had one (producted by Netbeans). So try this:
java -jar D:\NetBeansProjects\GetIPAddress\dist\GetIPAddress.jar
in a console window (cmd.exe on Windows). If this works, then your call as given by Sergey should work too. If it does not work, then you have to look at how to create this jar file.
