Hey guys,
Recently I've been working with exec in order to execute several scripts
via Java.
The thing is that I don't clearly understand how they work as I'm trying to
perform asycnhronous tasks and the process seems to keep on blocking
without continuing the execution, so what I did in the meantime is to
create manual Java Thread classes to perform all of them, which isn't
elegant at all.
For example, I'm trying to run Icecast as a background process, and keep on
executing and instantiating more background ones, but it seems that with my
approach it keeps blocking.
private void runIcecast() {
File file = new File("Icecast");
for (File s : file.listFiles()) {
if (s.getName().equals("icecast.bat")) {
DaemonExecutor executor = new DaemonExecutor();
executor.setWorkingDirectory(file);
executor.setExitValue(1);
CommandLine commandLine = new
CommandLine(s.getAbsolutePath());
try {
executor.execute(commandLine);
String line = "icecast -c icecast.xml";
commandLine = CommandLine.parse(line);
executor.execute(commandLine, new
DefaultExecuteResultHandler());
} catch (ExecuteException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
What should I do so a new Thread is created whenever the command is
executed? Or should I just create normal Thread classes as I've been doing
until now?
