Problem starting .bat file from java code on windows 2003

[Ivica Boskovic]

I am trying to start some bat file from java code. On almost the same server (windows 2003 64 bit) which is STAGING environment, everything works fine, but on the Production environment, bat file is simple not started. Anybody has any idea (running out of it)?

Here is the code:


try {
log.info("Calling external command: ");
Process proc = Runtime.getRuntime().exec("cmd /C start D:\\start.bat");
proc.waitFor();
} catch (Exception e) {
log.error("Error:", e);
}

No exception is thrown.

Search for and read the Javaworld article "When Runtime.exec() won't". It will explain why Process.waitFor can (and often will) block.
I had a problem once with an external process blocking, and after reading this article the problem was solved in minutes.

Hi,

It looks like the process did not complete yet?!
Perhaps you'll find an answer here.

Otherwise, you should also share with us the content of batch file ...

It is executed, since when I put something like
log.info("...");

at the end, it is executed. I saw cmd in the list of windows processes.

It is always the same, no metter of the content of the bat file,
for example xcopy....

on staging environment works, on production no...
