Use False for waitForEnd then it should be an asynchroneous launch -
at least for me under Windows (should try at home on Linux ;-) ):
<code>public static int runProcess(String commandLine, boolean
waitForEnd, StringBuilder output)
{
int rc = 0;
boolean b = true;
boolean r = true;
Process prc = null;
BufferedReader comeIn = null;
BufferedWriter goOut = null;
Date started = new Date();
try
{
prc = Runtime.getRuntime().exec(commandLine);
}
catch (IOException ex)
{
//Log error
}
if (waitForEnd)
comeIn = new BufferedReader(new InputStreamReader
(prc.getInputStream())); //We expect the OS default encoding here
although recommended to specify format always.
if (output != null && comeIn != null)
{
String s = "";
String ls = getLineSep();
do
{
try
{
s = comeIn.readLine();
if (s != null)
{
output.append(s);
output.append(ls);
}
}
catch (IOException ex)
{
//Log error
b = false;
break;
}
} while (s != null);
try
{
if (comeIn != null) comeIn.close();
}
catch (IOException ex)
{
//Log Error
}
}
if (waitForEnd)
{
while (r)
{
try
{
rc = prc.exitValue();
r = false;
}
catch (IllegalThreadStateException ex)
{
//Process not finished yet
//You can check here if a timeout is reached if
you want - in "started" is the date and time when the process has been
started.
}
}
}
if (!b)
{
//Log error
}
return rc;
}</code>
