问题:

I'd like to call the java keytool during runtime execution providing dynamic arguments. Here's what is working under Windows, but not under Linux (Ubuntu) same Java 1.6.0:

File f = new File("mykey.jks"); StringBuilder command = new StringBuilder(); command.append(System.getProperty("java.home")             + System.getProperty("file.separator") + "bin"             + System.getProperty("file.separator") + "keytool"); command.append(" -genkey"); command.append(" -dname \"cn=foo,ou=bar,o=company,c=CH\""); command.append(" -alias myProduct"); command.append(" -keypass " + "testtest"); command.append(" -keystore " + f.getAbsolutePath()); command.append(" -storepass " + "testtest"); command.append(" -validity " + 3650); final Process pr = Runtime.getRuntime().exec(command.toString());  BufferedReader input = new BufferedReader(new InputStreamReader(     pr.getInputStream()));  String line = null; while ((line = input.readLine()) != null) {     System.out.println(line); }  int exitVal = -1; try {     exitVal = pr.waitFor();     System.out.println("Exited with error code " + exitVal); } catch (InterruptedException e) {     // handle }

The Output under Linux is

keytool error: java.io.IOException: Invalid keyword ""CN"

Running the command in the Linux command line (not starting in java), the code works. What am I doing wrong and how would the String[] look like when using

Runtime.getRuntime().exec(String[])

Thanks in advance!

I recommend using http://docs.oracle.com/javase/6/docs/api/java/lang/Runtime.html#exec(java.lang.String[]) instead

Then you dont have to worry about escaping each argument which you are not doing here

String args [] = {arg1, arg2, "-dname", "dNameArguments"};
