run an external program

Hi all, I ask here also if I'm not sure is a Swing problem...but no idea where this question can go...

So : I have a java program that read a .xml file. This xml file is created by another program ( pdftohtml.exe).

now if I use the console( eclipse ) then I can get the .exe run and generate the xml file I need... with this:

Code :

---

	private void convert() {
		try {
			Runtime rt = Runtime.getRuntime();
 
			File my_file = new File(tP);
			my_file.mkdirs();
 
			File my_file2 = new File(tP + "\\pdf2xml.dtd");
			this.fos = new FileOutputStream(my_file2);
			this.osw = new OutputStreamWriter(this.fos);
			build_dtd();
 
			String cmd = "pdftohtml -xml " + sP + " " + tP + "\\data";
 
			Process p = rt.exec(cmd);
			p.waitFor();
		} catch (Exception e) {
			new Warning(e.getMessage(), true);
		}
 
	}

---

Now I have done a GUI and I have build an executable .jar file...
The problem is that now the program doesn't work... it tell me that the .exe file can not be found and so the xml is not generated and so my program is not working...

I hope that the problem is clear and that someone can help me...

Is the .exe file on the OS's path so it can find it? Open a command prompt change to a folder without the .exe file and enter the name of the .exe to see if the OS can find the .exe file.
How is the .exe found when you execute the program from your IDE? Is it in a local folder?

Hi, yes...the .exe file is on the workspace program folder ( but I have also tried to put it in the src/programm/file.exe (where there is also the .java class that use it) and tried to load using : String cmd = pdfXmlConverter.class.getResource("pdftohtml.exe") .getPath()+" -xml " + sP + " " + tP + "\\data"; to locate it...) as before it work when I run the program from eclipse...and doesn't work when packed in runnable .jar and launched...

Hi, I'm really sorry for this stupid question...

the problem was that we need to place the .exe file in the same directory where there is the .jar .

Thank you very much...

See you soon...

The OS will not try to execute a .exe file from inside of a jar file.

For testing try copying the jar file and the .exe file to a empty testing folder and open the jar file to see if it finds the .exe file when it is in the same folder as the jar file.
