Runtime.exec() then kill parent process, then you lose the System.out

If I do this:
in Proggie 1:
Process proc = Runtime.getRuntime().exec("proggie");
System.exit();in Proggie 2:
System.out.println("some string"); // goes nowhere??How can I redirect Proggie 2 System.out to the console that was used to start Proggie 1?

How can I redirect Proggie 2 System.out to the
console that was used to start Proggie 1?No way with current Java. This is a long and sad story that Java does not have i/o redirection. See for example one of the entries in the bug database:

Executing jar from java code, then kill parent java code

Please suggest if there is any best way around on executing jar from java code then killing parent java code.
a) I have desktop based java application say "Monitor.java" which runs every 5 minutes.
b) How can I START external java application say "execute.jar" from Monitor.java THEN EXIT Monitor.java
I tried various options using "ProcessBuilder" and calling bat file but I need Monitor (parent application to EXIT, immediately after calling child (execute.jar)
Try1) ProcessBuilder builder = new ProcessBuilder("java -jar execute.jar");
Process process = builder.start();
Try2) Runtime r = Runtime.getRuntime();
Process p = null;
p = r.exec(new String[] { "cmd", "/c", "start C:/temp/Test.bat" });

I have a requirement to transfer data from one db to another db from Java Application Layer.Maybe, maye not. We get all sorts of weird "requirements" - which are nothing but thoughts or proposed solutions.
But,
Did the "requirement" mention whether the table existed already or not in the target database? - If not, did it tell you to create it - drop/create it?
Did the "requirement" deliver some explanation to why this copying was neeeded? - Are we talking replication? - Or a one time cloning?
Etc, etc,
Personally I would always argue against a "reuirement" like that. - It just isn't the way to do it. Period.
Regards
Peter
P.S: If you are satisfied with what COPY does, then you could let Java make an OS call and do it from there?

In Exports sales process, how you configure the Duty Draw Back

in my case
we r creating Exports but
duty unavailability of time and time taking process in export processing
we are creating Excise invoice and cenvat is debited .
now we r asking the govt. for the duty draw back for the value already cenvat is debited with proper documents like ARE1 etc.
how to manage this duty back and what r the replications or changes thereafter
thanks in advance

HT1529 I have multiple users on my Mac and I was wondering how you tell the system to retain all the user names so they don't have to enter their email addresses every time ???

I have multiple users on my Mac and I was wondering how you tell the system to retain all the user names so they don't have to enter their email addresses every time ???

Email addresses into what?
Each user should have their own account and password to log in. Each is independent of the other. So for Mail each has their own Mail account if they set one up in Mail.
That's the way it should be set up. Are you using a single account and allowing multiple users to use that one single account? If so then in Mail at least you could set up individual mail accounts. But everything else in the system is shared.

Job also cancelled due to process termination. See the system log

Hi,
You need to check that program in debugging for the Backgournd process.
For doing the debugging of the background process do the following steps.
1)go sm37 and select your job.
2)in the command line just type JDBG (not the /nJDBG OR /oJDBG) and hit enter. it goes to the debuggin mode.
Thanks

How do you manage photos if you lose the computer your iphone was synced with?

how do you manage photos if you lose the computer your iphone was synced with?

Are you talking about photos that were synced to your phone? If so, the photo sync is one-way: Computer to phone. Apple makes no provision to extract these photos from your phone, you'll have to use third-party software to do so. Note: photos synced to your phone were reduced in resolution for display on your phone, there is no way to recover their full resolution.

Runtime.exec() and fork() and Process

So let me see if I understand this correctly, and if I don't please fill me in. If I call the following piece of codeRuntime.getRuntime().exec("chgrp rcsweb " + path+fs+orgName);
Runtime.getRuntime().exec("chmod 660 " + path+fs+orgName);where path is the real path to a file, fs is short for File.spearator and orgName is the name of a file, then in the Unix environment, it will fork off a process.
First, I seem to remember one forum topic that mentioned not forgetting about killing the process returned by exec, so I guess I need to add that to my code.
Second, since I am forking off this process inside of a J2EE container, am I actually forming off the entire container, or just the Servlet where Runtime is called, or what?
Third, how can I prevent the error java.io.IOException: Not enough space
at java.lang.UNIXProcess.forkAndExec(Native Method)
at java.lang.UNIXProcess.<init>(UNIXProcess.java:54)
at java.lang.Runtime.execInternal(Native Method)

at java.lang.Runtime.exec(Runtime.java:413)
at java.lang.Runtime.exec(Runtime.java:356)
at java.lang.Runtime.exec(Runtime.java:320)when I do not have the option of changing my VM size? Is killing the Process (and using waitFor()) going to take care of this issue?
I appreciate your help.

OK, after writing a few test programs, it is indeed clear..on unix (at least on solaris) when calling runtime.exec(..) The ENTIRE VM does indeed get forked. Therefore if your current Memory allocation for you VM is sitting at say 64MB (or you initial memory setting), another 64MB process will be created, even if you doing something as a simple
exec("ls");
I also tried putting runtime.exec call in its own thread hoping that if it was not in the main thread, that only that process would be forked..to no avail..the entire vm is indeed forked everytime...making runtime.exec damn near useless for server side work, and very dangerious..as you can essentialy assume you always need 2x your memory requirements.
If anyone has figured out a workaround...any suggestions greatly appreciated.
Some thoughts on some work-arounds
1. Run 2 VMs (then when native calls are required..send a message to the 'native-calling vm' (insure its memory footprint is very low)
2. Write your exec method via JNI (or does JNI calls also result in a fork of the vm on unix..)
Test code below (threaded version)
import java.util.*;
import java.io.*;

     public void run()
          int loops = 0;
          while (true)

               System.out.println("---- iteration " loops "---");
               makeNativeCall();
     public static void main(String[] args)
          try
               System.out.println("testing on OS: " + System.getProperty("os.name"));
               // Allocate a nice chunk of memory

Problems with Runtime.exec() and certain Unix processes

Certain Unix processes don't behave correctly when run from Java using Runtime.exec(). This can be seen by running /bin/sh and trying to interact with it interactively. The issue appears to be that /bin/sh (and many other Unix tools) are checking the file handles on the spawned process to see if they are associated with a TTY.
Is there any way to associate a process spawned by Runtime.exec() with a terminal or alternatively, is there a JNI library available that would setup the process correctly and still provide access to the input and output streams?
Our objective is to have the flexibility of expect in being able to run and interact with spawned processes. A bug was opened at one point but closed back in 1997 as being a fault in the spawned process, not Java.
Bug ID: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4058689

#include <stdio.h>
void doit() {
int c;
        while((c=getc(stdin)) != EOF) {
                printf("%c",c);
int main() {
        freopen("/dev/tty", "r", stdin);
        doit();
}This program reopens its standard input against /dev/tty and catenates it to stdout. And voila, it takes its standard input from the terminal, even though it was started with stdin against /dev/null..

How can I know if a process is running in the system???

Hello all,
I generate a pdf file with Reports Builder called from Forms Builder.
This pdf is printed in the default printer with the command line "start AcroRd32.exe /p /h path_file", inside host command, which open the Acrobat Reader and prints the document in the default printer.
After the document is printed the document is closed but not the Acrobat Reader program.
I need an instruction to know if the acrord32.exe is running in the system.
Could anyone help me?
Thank you very much for advance,
Jordi

do you use the commandline, because you want to print directly to your default-printer?
then have a look at the orarrp - toolset on otn.
It's a technique, which directly prints via MIME-extensions of your browser. Internally Adobe is used for this direct print, but you only have to install a little program on your client.

Can you listen to System.out ?

Good morning form. Is there a way to listen to System.out?
This could be useful in testing. You could compile a test version of the app and report all Sys out activity then turn it of in production (or not). The point would be to be able to apply this to applications after they were written. (as in not a consideration at the time the app was written).
I know if the app is run from a command line you can pipe the output to a file.
Thanks
ST

STHi, you should use logging instead. E.g. Log4J or java.util.logging

Changing a folder name means you lose the icon?!

that's nuts.
i hate sports so i changed the 'sports and entertainment' to 'entertainment' and i lost the lil' icon on that folder. now it's an empty blank lookign folder. how annoying. did i f it up for good? any ideas on how to get it back short of pressing the 'reset all icons' or something liek that that i saw which leads me to think it will defualt the ENTIRE home screen to how it was when i frist received it?
aargh!

Hi and welcome to the forums!
Was this folder provided by the carrier or a folder you created?
If it's carrier specific changes are it will be recreated when you reregister the phone and resend service books.
Try this:
Go to options advanced options, Host Routing Tables, click to enter. DO NOT click on any listing.
Press menu key, and select register now.
You will get a verification message. Then go to email settings and send service books.
You will get an email per account. Once complete, check all folders to see if it has returned.
Personally I do not use the majority or the vendor apps. I create a folder for all the applications I do not use.
I place all the icon in it, hide the icons, and then hide the folder. This was I get a clean desktop and I don't
accidentally starts an unwanted app. I do the same with all the email icons for accounts. I just use the main message queue.
Let me know if this is what you were asking.
Thanks,
