Java.lang.Process output stream problem

Hi, I have a program that starts a process (java.lang.Process) using the java.lang.Runtime.exec() and it attemtps to interface with it using the provieded io streams. I have both the output and error streams being handled on their own threads and I have a hashmap of output lines/command pairs that are checked so that when the process outputs certain lines to the console it feed the proper input into the process. My problem is that when I feed the input into the process it dosen't respond to it almost like the user hasn't pressed enter, The process hangs. I have tried using /n /r and permutations thereof but nothing works. The thread does read the lines from the process and does output to the process from what i can gather. Can you help me!
here is some of the code..
public void run() {
try {
     //the process's output
     InputStreamReader isrOutput = new InputStreamReader(inOutput);
     //the process's input(our output)
     PrintWriter pw = new PrintWriter(outInput);
     String line = null;
     while(true){
          if(brOutput.ready()){
               line = "";
               while(brOutput.ready())
     line+=(char)brOutput.read();
               System.out.print(line);
               if(commands.containsKey(line)){
     pw.println((String)commands.get(line));
     System.out.println((String)commands.get(line));;
} catch (IOException ioe) {
          ioe.printStackTrace();
}Thanks

Oops.. i forgot to flush my PrintWriter /blushing......... Thanks

Java.lang.Process input stream waiting until process is complete to print

I have tried to simplify this problem as much as possible. Basically, I have a java.lang.Process which executes a simple C program.
test.c
#include <stdio.h>
#include <unistd.h>
int main()
printf("foo\n");
sleep(2);
printf("bar\n");
...The process has an input stream and error stream handler each on a separate thread. I have tried both buffered and unbuffered (BufferedReader, BufferedInputStream, InputStreamReader...) stream handlers. Both produce the same problem of waiting until the process has exited to receive anything from the process's streams.
The only time this does not happen is when I call fflush(stdout); after each printf(). This can't be a solution because the real application calls a massive C application which would require thousands of fflush()'s to be added. What is causing this to happen? This doesn't happen when the C program is executed from the shell. Is there a way the InputStream can be forced to extract from the stream?

hi.....
I have closed the output stream of the process as you told me to do...
The hitch is that, if my program contains only printf() statements,it works fine
as soon as scanf() statement is encountered within the C code,it is totally neglected,and the output comes as if no scanf() statement existed in the C code.
Consequently the thread doesnt wait for input which was bound for scanf() from the thread
the code...

Get complete output from java.lang.Process

How do I get the complete output from java.lang.Process?
By the time I've started reading from Process.getInputStream() the process has already terminated...

Problem with starting a sqlplus-process via java.lang.Process

Hi,
I want to start a sqlplus-Process from a java-application via java.lang.Process. Works great with XP. On a W2K-Machine, the process is started (I can see it in the Taskmanager), but it doesn't connect to the db - the OS-process hangs, also the java-application which invoked the process.
If I start a sqlplusw.exe-Process instead of sqlplus.exe, it works as well.
Does anybody know what's going wrong ?
I'm using java 1.5.0_11 and Oracle Database 10g Enterprise Edition Release 10.2.0.3.0
Thanks in advance
Jens

java.lang.Process can be used to perform an OS Shell to launch specific tasks. But why are you interested in specifically launching sqlplus from here?

Problwm with java.lang.Process

I am using java.lang.Process to read the output of a command, it works fine with one word commands such as "ls", but a command with a pipe and and arguments returns no output, for example "who | grep root".
Any ideas!

for example "who | grep root".
Any ideas! Probably because you really should have nothing returned. Try to give the output of the first command as an input to the second one but not through a pipe; use java.lang.Process twice.

Is it possible to use the java.lang.ProcessBuilder to execute a Java process pointing it to jvm.dll instead of java.exe? I'm using the JavaFX self contained application packaging and it creates a runtime/jre/bin directory that contains jvm.dll, but not java.exe.I don't get the line of questioning of this thread. If you're using the JavaFX stuff the answer must lie in the JavaFX documentation. It seems to indicate that it generates an executable of its own which will likely wrap the jvm DLL, so you should be invoking the generated executable in ProcessBuilder.

Java.lang.Process.exec()

I have read a article about the "java.lang.Process.exec()" (url:http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html)
Having some questions with the example in it.
The example code:
import java.util.*;
import java.io.*;
public class BadExecJavac
    public static void main(String args[])
        try
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("javac");
            //int exitVal = proc.exitValue();
            int exitVal = proc.waitFor();
            System.out.println("Process exitValue: " + exitVal);
        } catch (Throwable t)
            t.printStackTrace();
}The process can run but never complete.
Why? Just because when invoke the javac.exe without any argument,it will product a set of usage statements that describe how to run the program and the meaning of all the available program options.So the process is in deadlock.
The question is, when i change the exec("javac") to exec("javac a.java"), in which the "a.java" is not exist, so the jvm should product error:
error: cannot read: a.java
1 error
But after i changed the code and run the class, at this time the process can run and complete.
The two codes both product some statements,but why the first one never complete,but the second did. Why?

import java.util.*;
import java.io.*;
public class A
    public static void main(String args[])
        try
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("javac");
            InputStream is = proc.getErrorStream();
            int i=0;
            while ((i = is.read()) != -1)
                System.out.print((char)i);
            // int exitVal = proc.exitValue();
            // int exitVal = proc.waitFor();
            // System.out.println("Process exitValue: " + exitVal);
        } catch (Throwable t)
            t.printStackTrace();
}usng this modification, i could see some error messages.
because exec(cmd) executes the command in a separate process, it will not display the results on the current console. If you want see the results, you should use getInputStream() and getErrorStream().
good luch ^^

Exception in thread "main" java.lang.Error: Unresolved compilation problem

The reason (as others have pointed out) is, that some paths through your method don't return a value.
I'll re-write your code in the code-style that I usually use, because then it might be easier for you to see the problem:
public boolean find(MusbachJ_Person person,BstNode node)
     if(node.intData.compareTo(person)==0) {
          return true;
     if( node.leftNode != null ) {
          find(person,node.leftNode );
     if( node.rightNode != null ) {
          find( person, node.rightNode);
     else {
          return false;
}There are two prolbems. I'll spell out the first and let the other one for you to find:
1.) you don't do anything with the return-values of the find-methods you are calling. What do you want to do with them?
2.) What do you return if the current node is not the one that you want and you've got a right node?

[java.lang.Process] Howto simulate ENTER ?

Hi there!
I need to control an interactive command-line tool from java (smbclient) and for this task I use Process with getOutputStream().
However I want to send commands to the native-program like: Process.getOutputStream.write("exit\n".getBytes()) but it simply does not work :-(
I think the native programs does not recognize the "\n" as <ENTER> .
Any ideas howto solve this problem?
Thanks you in advance, Clemens Eisserer

Well, thanks for the tips!
Since I am running Unix '\n' shoulb we enough, but thanks for remembering me g
Well, I actually forgot to flush the output-Stream. Nobody is perfect ;-)

Java Input and Output streams

I have maybe simple question, but I can`t really understand how to figure out this problem.
I have 2 applications(one on mobile phone J2ME, one on computer J2SE). They commuinicate with Input and Output Streams. Everything is ok, but all communication is in sequence, for example,
from mobile phone:
out.writeUTF("GETIMAGE")
getImage();
form computer:
reply = in.readUTF();
if(reply.equals("GETIMAGE")) sendimage()
But I need to include one simple thing in my applications - when phone rings there is function in MIDlet - pauseApp() and i need to send some signal to Computer when it happens. But how can i catch this signal in J2SE, because mayble phone rings when computer is sending byte array? and then suddnely it receives command "RINGING"....?
Please explain how to correcly solve such problem?
Thanks,
Ervins

Eh?
TCP/IP is not a multiplexed protocol. And why would you need threads or polling to decipher a record-oriented input stream?
Just send your images in packets with a type byte (1=command, 2=image, &c) and a packet length word. At the receiver:
int type = dataInputStream.read();
int length = dataInputStream.readInt();
byte[] buffer = new byte[length];
int count, read = 0;
while ((count = dataInputStream.read(buffer,count,buffer.length)) > 0)
read += count;
// At this point we either have:
// type == -1 || count = -1 => EOF
// or count > 0, type >= 0, and buffer contains the entire packet.
switch (type)
case -1:
// EOF, not shown
break;
case COMMAND: // assuming a manifest constant somewhere
// process incoming command
break;
case IMAGE:
// process or continue to process incoming image
break;
}No threads, no polling, and nuthin' up my sleeve.

You are passing the entire command as one String and the string is being interpreted as the name of the program and no arguments.
See the Javadocs for ProcessBuilder. It has an example that shows how to pass the cmd, and each argument as separate Strings.
Get the Javadoc example working first and then substitute your command and arguments.
Starting a new process which uses the default working directory and environment is easy:
Process p = new ProcessBuilder("myCommand", "myArg").start();
Here is an example that starts a process with a modified working directory and environment:
ProcessBuilder pb = new ProcessBuilder("myCommand", "myArg1", "myArg2");
Map<String, String> env = pb.environment();
env.put("VAR1", "myValue");
env.remove("OTHERVAR");
env.put("VAR2", env.get("VAR1") + "suffix");
pb.directory(new File("myDir"));
Process p = pb.start();

About java.lang.Process class?

hi, i am executing one batch file (it contains 2 executable statements) through java.lang.Runtime class exec method like this..Process p1=r.exec("cmd /K start .\\Skeletons\\reports\\FormatFiles\\"+strDTab+".bat");.. i want to get the output of this process is it success, failure or suspect?. how to use the waitFor() method of Process class in this situation?. and also the execution of the batch program will give some status (if fail it will throw some exception), i want to catch the status. depending on the status i will decide proceed to further statements or not?..

You use waitFor() by calling it on the process you get back from the exec()
If you want examples use google to find them.

          }catch (SQLException sqle) {
            System.out.println("JDBC error:" + sqle.getMessage());
            sqle.printStackTrace();
          return conn;
      }then on every function I call it like
private int getFound(String UNumber) throws Exception {
        Connection conn = null;
        CallableStatement calstat=null;
        ResultSet rs = null;
        try {
            conn = pool.getConnection();
            calstat = (CallableStatement) conn.prepareCall("{call DuplicatePost(?)}");
            calstat.setString(1, UNumber);
            rs = calstat.executeQuery();
            tarCount = 0;
            while (rs.next()) {
                tarCount++;
        } catch (SQLException se) {
            System.out.println("JDBC error:" + se.getMessage());
            se.printStackTrace();
        } catch (Exception e) {
            System.out.println("other error:" + e.getMessage());
            e.printStackTrace();
        } finally {
            try {
                if (rs != null) {
                    rs.close();
                if (calstat != null) {
                    calstat.close();
            } catch (SQLException e) {
                e.printStackTrace();
        } //end finally
        return tarCount;
    }// end function
}// end
