I am unable to call a shell script from my java code. Here is my code. Can anyone let me know what I am missing here.
protected boolean shellExecute() throws InterruptedException {
try {
Process p = Runtime.getRuntime().exec("/home/baibhav/try_scripts/javacall.sh");
} catch (IOException e) {
e.printStackTrace();
return false;
}
return true;
}
Try using sh before the script name
Process p = Runtime.getRuntime().exec("sh /home/baibhav/try_scripts/javacall.sh");
If you are getting IO execption, please check your scripts path
If the script has output, you need to get the returned Process' output and read from it the process does not block.
Process p = Runtime.getRuntime().exec("/home/baibhav/try_scripts/javacall.sh");
InputStream scriptStdout = p.getInputStream();
// Read from input stream and proecess it.
// In finally block:
scriptStdout.close();
You didn't say whether you had an exception thrown or whether the system just hanged. If it hanged, that's probably the reason.
Also, consider using ProcessBuilder instead.
Exception?
