system cannot find the file specified up vote 6 down vote favorite 2 I am writing a program in java which would execute winrar and unzip a jar file for me placed in h:\myjar.jar into the folder h:\new. My java code goes something like this import java.io.File; import java.io.IOException; public class MainClass { public static void main(String[] args) { Runtime r=Runtime.getRuntime(); Process p=null; try { java createprocess error=5 access is denied File dir=new File("C:/Program Files/WinRAR"); p=r.exec("winrar x h:\\myjar.jar *.* h:\\new",null,dir); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } When i execute this, i am getting this error java.io.IOException: Cannot run program "winrar" (in directory "C:\Program Files\WinRAR"): CreateProcess error=2, The system cannot find the file specified at java.lang.ProcessBuilder.start(Unknown Source) at java.lang.Runtime.exec(Unknown Source) at java.lang.Runtime.exec(Unknown Source) at MainClass.main(MainClass.java:16) Caused by: java.io.IOException: CreateProcess error=2, The system cannot find the file specified at java.lang.ProcessImpl.create(Native Method) at java.lang.ProcessImpl.

Join them; it only takes a minute: Sign up Can't execute javac or other command line applications in Java using ProcessBuilder http://stackoverflow.com/questions/19621838/createprocess-error-2-the-system-cannot-find-the-file-specified under Windows 7 up vote 0 down vote favorite I'm trying to execute javac from Java using ProcessBuilder but i get no output and nothing happens. I tried reading the input stream (as there is a bug where the process hangs if i don't read it) but still no results. I originally passed all required parameters to javac but it was not working, so i simplified it down to http://stackoverflow.com/questions/4985038/cant-execute-javac-or-other-command-line-applications-in-java-using-processbuil just javac (which should print the help message). i tried running "C:\Windows\System32\cmd.exe /c C:\\"Program Files\"\Java\jdk1.6.0_23\bin\javac.exe" "C:\\"Program Files\"\Java\jdk1.6.0_23\bin\javac.exe" and surrounding the entire path to javac with double quotes but still nothing. I get the error Cannot run program "C:\Windows\System32\cmd.exe /c C:\"Program Files"\Java\jdk1.6.0_23\bin\javac.exe": CreateProcess error=2, The system cannot find the file specified but if i copy the command and run it from the command line it works fine. I am aware of using the JavaCompiler class to compile my files but i would prefer to get this problem fixed first as i can't run any dos application or .bat file from Java. I can run GUI programs like notepad.exe fine though. String[] commands = new String[]{ "C:\\Windows\\System32\\cmd.exe /c C:\\\"Program Files\"\\Java\\jdk1.6.0_23\\bin\\javac.exe" }; logger.log(Level.INFO, "About to run javac with the command below:"); String commandToOutput = ""; for (String command : commands) { commandToOutput += command + " "; } logger.log(Level.INFO, commandToOutput); ProcessBuilder processBuilder = new ProcessBuilder(commands); Process p = processBuilder.start(); Edit 2 String[] commands = new String[]{ "C:\\\"Program Files\"\\Java\\jdk1.6.0_23\\bin\\javac.exe", "-d", "\"" + tempDir + "\"", "-classpath", classpath }; Edit 3 why is it that the second commands array works but the first does not below. //this gives me CreateProcess error=5, Access is denied commands = new String[]{ "C:\\\"Program Files\"\\

(assoc/ftype) up vote 3 down vote favorite 2 Does anyone know why these two statements result in the shown exception? Runtime.getRuntime().exec("assoc .vlan=\"file type description\""); Runtime.getRuntime().exec("ftype \"file type description\"=" + System.getProperty("user.home")+ "\\folder 1\\folder 2\\my executable.exe\" /inject \"%1\""); And Here's the Exception. java.io.IOException: Cannot run program "assoc": CreateProcess java createprocess error=2 error=2, The system cannot find the file specified at java.lang.ProcessBuilder.start(ProcessBuilder.java:1029) at java.lang.Runtime.exec(Runtime.java:615) at java.lang.Runtime.exec(Runtime.java:448) at java.lang.Runtime.exec(Runtime.java:345) All right, I've changed this but still the association is not made whereas the very same command is executable and working under the cmd command prompt. Runtime.getRuntime().exec("cmd.exe /c assoc .vlan=\"file type description\""); Runtime.getRuntime().exec("cmd.exe /c ftype \"file type description\"=\"" + System.getProperty("user.home") + "\\folder 1\\folder 2\\my executable.exe\" /inject \"%1\""); Any complementary suggestion? Thank you! java exec share|improve this question edited Dec 15 '11 at 4:53 asked Dec 15 '11 at 3:51 Sam 90731934 exec("assoc .vlan=\"file type description\""); If that is making a file association, note that Java Web Start is able to add file associations for an app. Further, it can do it on Windows, OS X & *nix. See the demo. of the file services for ..demo and downloadable source. –Andrew Thompson Dec 15 '11 at 4:41 add a comment| 1 Answer 1 active oldest votes up vote 7 down vote accepted As it turns out, assoc and ftype are built-in shell commands and NOT executable files.

Renamed it to cmdx , runs fine. So any program named as cmd does not run at all. The applet jar is signed.

Alka Gupta Greenhorn Posts: 4 posted 4 years ago More information Runtime.getRuntime().exec(new String[] { "C:\\cmd.exe"}); as well as Process p = new ProcessBuilder("C:\\cmd").start(); None of them work, It used to work before with jre 1.6 and now we started certifying 1.7 for our software we this issue. I have read many forums and have asked on Java forum, windows forum and oracle forum but I havent got any answer yet Richard Tookey Bartender Posts: 1166 17 I like... posted 4 years ago I must be missing something . Why do you need to name the executable you are trying to exec() cmd.exe ? Why can't you call it something like fred.exe ? Alka Gupta Greenhorn Posts: 4 posted 4 years ago Runtime.getRuntime().exec(new String[] { "cmd.exe", "/c", udoc.getFilename() }); This is the original code I'm trying to execute and fails on cmd.exe so I broke it to see how can I fix the cmd problem Darryl Burke
