External commad execution using Runtime
hi,
in the following code i have a problem. While I try execute with big query?
1. Runtime run = Runtim.getRuntim();
2. Process p =run.exex("c:\\script.bat");
script.bat contains mysql command line operation for eg:
mysql -u root databasename -e "select * from testTable"; >> c:\\test.txt
the above simple query not make a problem. I got the file test.txt
But when I try to add more colums and n no..of joins and some where conditions. The program executed fine but i didn't get the file test.txt.
Any iead.
1. I used a thirdparty tool for accessing the database.
2. it construct the select quey based on my input, the query contains base table, sub table and all joins where clause, having & group by clauses.
3. Main reason is, i have huge data.

--Hi,
When you are logged in to the OS, can you do an "su" to the "scripts" user using this exact password (passwords are case-sensitive) ?
Also make sure that you have libpam.so located somewhere in $LD_LIBRARY_PATH and that it points to a real file.
external jobs with credentials use jssu, but I don't think permissions on jssu are the problem here (it should be setuid to root).
Hope this helps,
Ravi. -
Execute an external program using Runtime class
How to execute an external java program using Runtime class?
I have used ,
Process p=Runtime.getRuntime().exec("c:/j2sdk1.4.0/bin/helloworld.java ");
But it throws a runtime IOException error:2 or error:123.
Help me with the code. Thanks in advance.Create Runtime Object and attach to system process.Try this code
import java.io.*;
public class ExecuteExternalApp {
public static void main(String args[]) {
try {
Runtime rt = Runtime.getRuntime();
//Process pr = rt.exec("cmd /c dir");
Process pr = rt.exec("c:\\ yamessenger.exe"); //give a valid exe file
BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));
String val=null;
while((val=input.readLine()) != null) {
System.out.println(val);
int exit = pr.waitFor();
System.out.println("Exited with error code "+exit);

It works fine when the swf is opened in IE.
Can anyone please help me in solving the issue.thank you
i have tried to use this.parent.Click_To_Close but it gives compilation error
i checked the tutorial about custom events i think its little complex for me now to understand the typeriter app.
also i cheked the similer thread and tried to test that code myself..i found that the last block of main movie does not works and does not unload the loader2. however all the trace are showing in the output windows that i added to check the code but last trace from the main movie is not showig...
trace("child removed from Main Movie")
so if this can work somehow i will use this method of event dispatch in my application that i am working...
Thank you
-----main movie ---------
var loader1:Loader = new Loader();
var loader2:Loader = new Loader();
loader1.contentLoaderInfo.addEventListener(Event.COMPLETE, assignMovie1Listener);
loader1.load(new URLRequest("movie_1.swf"));
loader2.load(new URLRequest("movie_2.swf"));
addChild(loader1);
addChild(loader2);
function assignMovie1Listener(evt:Event):void {
MovieClip(evt.currentTarget.content).addEventListener("eventTriggered", removeLoader2);
trace("listner is listning..")
function removeLoader2(evt:Event):void {
loader2.unloadAndStop();
removeChild(loader2);
loader2 = null;
trace("child removed from Main Movie")
//------------- movie_1.swf code:
removeMovie2_btn.addEventListener(MouseEvent.CLICK , removeMovie2);
function removeMovie2(event:MouseEvent):void
dispatchEvent(new Event("eventTriggered"));
trace("event triggered form Child Movie-1");
as u can see when i click close button its triggering the trace from movie-1 but its not unloadign the movie2 -
Trying to run external script using Runtime.exec
Hey,
I am trying to use Runtime.exec(cmd, evnp, dir) to execute a fortran program and get back its output, however it seems to always be hanging. Here is my code snippet :
Process process = Runtime.getRuntime().exec(
"./fortranCodeName > inputFile.txt" , null, new File("/home/myRunDir/"));
InputStream stream = new InputStream(process.getInputStream());
InputStream error = new InputStreamr(process.getErrorStream());
BufferedReader stdoutReader = new BufferedReader(new InputStreamReader(stream));
BufferedReader erroutReader = new BufferedReader(new InputStreamReader(error));
System.out.println(stream.available()); //returns 0
System.out.println(error.available()); //returns 0
while (true) {
String line1 = stdoutReader.readLine(); //hangs here
String line2 = erroutReader.readLine();
if (line1 == null) {
break;
System.out.println(line1);
System.out.println(line2);
}I know for a fact that this fortran code prints out stuff when run it in terminal, but I don't know if I have even set up my Runtime.exec statement properly. I think I am clearing out my error and input streams with the whole reader.readLine bit I have above, but I am not sure. If you replace the command with something like "echo helloWorld" or "pwd", it prints out everything properly. I also am fairly confident that I have no environmental variables that are used in the fortran code, as I received it from another computer and haven't set up any in my bash profile.
Any Ideas?Okay, so I implemented the changes from that website (thanks by the way for that link, it helps me understand this a little better). However, my problem is still occuring. Here is my new code:
class StreamThread extends Thread {
InputStream is;
String type;
StreamThread(InputStream is, String type)
this.is = is;
this.type = type;
public void run()
try
InputStreamReader isr = new InputStreamReader(is); //never gets called
BufferedReader br = new BufferedReader(isr);
String line=null;
while ( (line = br.readLine()) != null)
System.out.println(type +">"+ line);
} catch (IOException ioe)
ioe.printStackTrace();
try {
Process process = Runtime.getRuntime().exec(
"./fortranCodeName" , null, new File("/home/myRunDir/"));
StreamThread stream = new StreamThread(process.getInputStream(), "OUTPUT");
StreamThread errorStream = new StreamThread(process.getInputStream(), "ERROR");
stream.start();
errorStream.start();
int exitVal = process.waitFor(); //hangs here
System.out.println("ExitValue: " + exitVal); -

Monitoring a Process using Runtime.exce()
Hi,
In my Program, I'm using the
new BufferedReader(new InputStreamReader(Runtime.getRuntime() .exec("ps -ef | grep xmlfeed").getInputStream()));
The above statement is not returning any inputstream to the BuffredReader.
When I gave the command as "PWD", it's returning the lines as expected.
But it's not working even for "PS" command also.I'm running this in AIX machine.
Any Ideas,Please help....
Edited by: haijdp on Dec 21, 2007 1:11 AMHello! And sorry I didn't reply earlier. I hope the Original Poster will find revisit this thread and it helps him.
From your post I assumed that you were not a student trying to create some homework. That's why I felt free to simply code a solution and submit the code here. But first some remarks:
I don't think that your code can work. Runtime.exec expects an array of type String, where the first element is the command and subsequent elements are a command line option each. I don't think you can use the pipe and call several commands using Runtime.exec, but that's just a kind of guess. YMMV.
Running external Processes in Java is a bit complicated. Basically,
* It's good to run the process in it's own thread. That way the main program can continue without getting stuck.
* To extract stdout and stderr of your target process you must run two threads, one for stderr and one for stdout. Both threads extract the characters of their respective streams in a loop that runs inside the thread. Again, that way we avoid deadlocks, program getting stuck etc.
This explanation is terrible, I know - I think a slice of source code speaks louder than words. I have attached five java files which together make a little process runner which extracts stdout and stderr in a safe manner. To run:
* Cut'n paste them into five text files, one per class.
* Save the each text file as {contained-class-name}.java
* Compile the stuff
* Run RunnerDemo (When I ran it, I got a directory listing printed on the console)
Explanation sounds a bit sloppy, but I did it under the assumption that you are a seasoned java pro, so it should not pose any problems. Since you seem to be a different OS than I (AIX, I run Linux), the command may or may not work. Try other commands. For example, in the RunnerDemo class you could set the cmd field to this:
String [] cmd =
"ps",
"-A",
"-H"
};This would give you a process listing (works on Linux).
By the way, commands are passed as array. See Java documentation for java.lang.Runtime.exec (String []) for explanation of this array.
One problem I see in your command is that the output of ps is piped to some other program. Sorry, I don't know whether my code could achieve this. All it can do is to rum one single command with command line options. But you should be able to adjust the given example, so it supports piping to another program.
If you have any further questions, please don't hesitate to ask!

* Unfortunately, we haven't implemented any facility to stream characters to

How to execute external spawned process using java
Hi,
I am executing PGP from command line using java.
For adding the public key I use Runtime object like this
Runtime rt = Runtime.getRuntime();
Process process = rt.exec("pgp -ka "+"d:/Mangesh/pubkey/sandy.asc "+"C:/PROGRA~1/NETWOR~1/PGPNT/keyrings/pubring.pkr");PGP is executing this but inbetween it asked for confirmation "Do you want to add public key (y/n)"
I am providing data to process this way:
PrintWriter pw = new PrintWriter(new OutputStreamWriter( process.getOutputStream()));
pw.write('y');
pw.flush();But after this their is no execution from PGP and console remains until I closed it.
PGP is waiting for ENTER KEY
How can I provide ENTER KEY from java
This is right method ??? or any other options are available??
I am awaiting for your valuable suggestions .
Regards
Man479On Windows the "enter key" consists of two characters: carriage return and a line feed (\r\n). You may have to send both. If that doesn't work, pgp is not reading the reply through stdin, only through the console, and there's no way to pass the 'y' to it through Java.

IOException File not found - While using Runtime.exec
Hey All,
I have written a Java application which needs to start up another external application. I have executables for that external application for different platforms (Win32, PPC and Linux). When the Java application is started it detects the OS and starts up the right executable according to the OS. The executable loads up fine on Windows without any problems. But in both Linux and Max OS X I get this exception:
java.io.IOException: java.io.IOException: "/home/vilas/Documents/Project/build/CLISP/linux/lisp.run": not found
at java.lang.UNIXProcess.<init>(UNIXProcess.java:143)
at java.lang.Runtime.execInternal(Native Method)

at jplan.communication.lispserver.LispServer.run(LispServer.java:109)
at java.lang.Thread.run(Thread.java:534)lisp.run has all the necessary permissions. If I copy the string (/home/vilas/Documents/Project/build/CLISP/linux/lisp.run) and paste it in a terminal and press enter, the application starts up fine without any problems!! Can you please tell me what could be going wrong?
The following extra information maybe helpfull:
1) I use the exec(String command, String[] envp, File dir) version of exec.
2) The complete format of the command is as follows (one long string):
"/home/vilas/Documents/Project/build/CLISP/linux/lisp.run" -B "/home/vilas/Documents/Project/build/CLISP/linux" -M "/home/vilas/Documents/Project/build/CLISP/linux/lispinit.mem" -i loader.lisp
Thanks in advance for your time and efforts.I found the problem after extensively searing the forums (looking upto page 4 !! of the results). The problem was that I was using quotes to surround the paths in the command. If you copy and paste it in a terminal it will work fine but it does not work with runtime.exec. I am not sure, but I think the reason is that when a terminal is used, some pre-processing of the commands take place before they are passed onto the OS(shell). But while using runtime.exec, that pre-processing is not peformed and therefore some things will not work.
In order to fix the problem, I use quotes only when the OS is windows. In other cases(OS X, Linux) I escape the spaces i.e. replace " " with "\ ".
PS: The executable is a binary compiled from C code. -
External definition and used them as Data Type Templates
hi all
how to Develop external definition and used them as Data Type Templates .
Thank u
SwariHI
External Definitions: If a definition of the message structure exists in wsdl, xsd, dtd formats, we can use it in the integration repository by importing it as an external definition.
External Definations:
An external definition enables you to import a local WSDL, XSD, or DTD file to the Integration Repository and specify which parts of the schema to extract as the description for a message. You can use these extracted message schema as:
Output or input messages in message interfaces
Source or target structures for message mappings
There is a series of standard schema for describing the message structure at runtime. WSDL (Web Service Description Language), XSD (XML Schema Definition Language), or DTDs (Document Type Definitions) are often used to describe message schema. If a description of the message structure already exists in one of the above formats, you can use it in the Integration Repository by importing it as an external definition rather than re-entering it manually using the data type editor.

Question about using Runtime.getRuntime();
hi all
i have a question about using Runtime.getRuntime(). if i use this to get a runtime reference to run an external program, is it considered as starting a new thread inside the thread that starts it?
is it safe to do it in the Session EJB? if not, what can you recommand to do it? thankshi all
i have a question about using Runtime.getRuntime().
if i use this to get a runtime reference to run an
external program, is it considered as starting a new
thread inside the thread that starts it? No. Starting a process, starts a process. Threads have nothing to do with it.
is it safe to do it in the Session EJB? if not, what
can you recommand to do it? thanksSo what? Run another process? If you want to run another process in java then your choices are to use Runtime.exec() or use JNI. And using JNI will probably end up doing exactly the same thing as Runtime.exec().
"Safe" is harder. Typically to correctly use Runtime.exec() you must use threads. And as noted threads ideally should not be used. You can use them but if you do you had better understand why they didn't want you using them in the first place. You had also better be sure that you really want to wait for it to complete.
Other than that Runtime.exec() is safe because it can't crash the VM like other interfaces can (like JNI.) -
Executing external native processes using exec
Hi,
I am running an external process in the normal way (i.e using Runtime.exec to reutrn a process object, using process.waitfor() to wait for return code etc). However, what I need is for the external process to continue running after my java application has exitted. So far I have been unable to do this � it seems the external process is still somehow a child of my Java process.
Does anyone have any idea how to do this, or even if it is possible?
Thanks in advance!If you detach the child process (redirect stdin, out, err) from the starting one it should be no problem. waitfor() is of course not applicable.

Issue using Runtime.exec() to export a DB
hi ,
i'm trying to write a piece of code to export an oracle DB using Runtime.exec(). I searched the forums and came up a with a piece of code , modified it a bit .The issue is the system sometimes hangs while executing the code , it's like the proc.waitFor() never returns. However the execution is error-free if using a command like 'shutdown' instead of 'exp' .
this is my main
public class DBExporter
* @param args
public static void main(String[] args)
try
StreamReaderThread outReaderThread = new StreamReaderThread();
StreamReaderThread errReaderThread = new StreamReaderThread();
//StreamReaderThread ww = new StreamReaderThread();
Runtime rt = Runtime.getRuntime();
outReaderThread.start();
errReaderThread.start();
String command = "exp beta/beta@frsp_dbS file=\"c:/shop.dmp\" full=\"N\" ";
//command = "shutdown -s";
Process proc = rt.exec(command);
outReaderThread.setInputStream(proc.getInputStream());
errReaderThread.setInputStream(proc.getErrorStream());
//ww.setOutputStream(proc.getOutputStream());
System.out.println(proc.waitFor());
proc.getInputStream().close();
proc.getErrorStream().close();
proc.getOutputStream().close();
catch (Exception e)
e.printStackTrace();
}and this is the reader class
import java.io.BufferedWriter;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
*@deprecated
public class StreamReaderThread extends Thread
private BufferedReader br;
private BufferedWriter bw;
private StringBuffer sb;
private String newline;
private String line;
public StreamReaderThread()
br = null;
sb = null;
newline = null;
line = null;
public synchronized String getText()
if( sb == null )
return "";
return sb.toString();
private boolean flag = false;
public synchronized void setInputStream( InputStream is )
br = new BufferedReader(new InputStreamReader(is));
flag = true;
public synchronized void setOutputStream( OutputStream is )
bw = new BufferedWriter(new OutputStreamWriter(is));
flag = true;
public synchronized void run()
int i = 0;
try
while( !flag )
wait();
flag = false;
while( (line = br.readLine()) != null )
try
if( sb == null )
sb = new StringBuffer();
newline = System.getProperty("line.separator");
else
sb.append(newline);
sb.append(line);
catch( Exception e )
e.printStackTrace();
i++;
if( br == null )
break;
catch( IOException ex )
ex.printStackTrace();
catch( InterruptedException ex )
ex.printStackTrace();
}Looks like a bug in StreamReaderThread. I can't see that it ever exits the wait() call since no one is calling notify or notify all.

Using Runtime.exec to execute Java.exe
I am trying to use Runtime.exec to spawn a thread that runs java.exe, but havn't had any luck. I have two versions of code, the first one works (example 1), but I want to eliminate the use of "cmd /c" to keep system independance. The second example (example 2) does not work. Both versions work if invoked from the command line. I'm running Win2000. Any Ideas?
Example 1:
aProcess = aRuntime.exec("cmd /c java.exe
-cp "<MyClassPathHere>" <arg1> <arg2> <arg3> <arg4> <arg5>");
Example 2:
aProcess = aRuntime.exec("java.exe
-cp "MyClassPathHere" <arg1> <arg2> <arg3> <arg4> <arg5>");I think you mix two concepts: "threads" and "processes". A "thread" is a thread of execution inside the VM, but you want to actually start a new VM in a new process, which is an OS level thing, right?
I've tried Idea 2 also, same result: works if
i specify cmd c/, doesn't if I don't.It should work if java.exe is in your path... are you taking care of the standard streams of your process?
