Linux Run time coammnd error in Java.

[dmjpro]

I am trying run a command in Java,which runs in console of Linux properly.
But while I am trying to run in Java then it flushes errors.
What might be the possible reasons?

The command follows..
keytool -genkey -keyalg RSA -dname "CN=DEBASISBHAT TACHARYYA, OU=MS, O=IIT, C=IN" -validity 24 -alias debasis -keypass password -keystore /DATA/keystore/userkey/E84009.jks -storepass password

And the error ..what i m getting is ...
keytool error: java.lang.Runti meException: Usage error, OU=MS, is not a legal command

Please help me.
it's urgent!

Don't mention that it's urgent; it may be urgent to you but it isn't for me nor anyone
else. Can you show a bit of relevant code?

Yeah sorry!!!

[code=java]
String command = "keytool -genkey -dname \"CN=" +
keyStoreInfo.ge tCommon_name() + ", OU=" + keyStoreInfo.ge tOrganizational _unit() +
", O=" + keyStoreInfo.ge tOrganization() + ", C=" + keyStoreInfo.ge tCountry() + "\"" +
" -alias " + keyStoreInfo.ge tAlias() +
" -keypass " + keyStoreInfo.ge tAlias_password () + " -keystore " + keyStoreFilePat h +
" -storepass " + keyStoreInfo.ge tKeyStorePasswo rd() + " -validity " + keyStoreInfo.ge tValidity() +
" -keyalg RSA";

System.out.prin tln("Command : " + command);
isGenerated = runCommand(comm and);
[/code]

This is the runCommand method....
[code=java]
boolean runCommand(Stri ng command) {
boolean isCompleted = false;

try {
Process p = Runtime.getRunt ime().exec(comm and);
p.waitFor();
BufferedReader stdError = new BufferedReader( new InputStreamRead er(p.getErrorSt ream()));
//proc=rt.exec("k eytool -list -keystore keystore -storepass storepass");
BufferedReader stdInput = new BufferedReader( new InputStreamRead er(p.getInputSt ream()));
//proc=rt.exec("k eytool -list -keystore keystore -storepass storepass");
String s = null;

while ((s = stdInput.readLi ne()) != null) {
System.out.prin tln(s);
}
if (stdError == null) {

} else {
while ((s = stdError.readLi ne()) != null) {
System.out.prin tln(s);
}

}
isCompleted = true;
} catch (InterruptedExc eption ex) {
isCompleted = false;
Logger.getLogge r(KeyStoreGener ation.class.get Name()).log(Lev el.SEVERE, null, ex);
} catch (IOException ex) {
isCompleted = false;
Logger.getLogge r(KeyStoreGener ation.class.get Name()).log(Lev el.SEVERE, null, ex);
}
return isCompleted;
}
[/code]

In your runCommand() method, print out that command String and see what it is
actually trying to exec.

I am simply pass the command parameter.
Is there any chance to loose characters?
Why should i check that out as we copy the printed command
[code=java]
System.out.prin tln("Command : " + command);
[/code]
and paste the command to console and it runs properly.
What might be the reasons?

Just to be sure; what did it print? Was it the correct command string?

Josh I solved that problem.
Actually I read this link ...
Runtime.exec() pifalls and came to know the reality.
I used command array instead of using the whole command in a single string.
Thanks for your help Josh.

From what I can see from your posts above you were using a single String for
your command, not an array; so what's up?
