Running ls command from Java stroed procedure no output

Hi ,
I am trying to run ls command from java stored procedure in oracle
Process p = Runtime.getRuntime().exec("ls");
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
// read the output from the command
System.out.println("output of the command run:\n");
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
from java stored procedure in oracle.
i get output of println statments but it does not go into while loop to print from stdInput.
Result of running Java stored procedure is -
output of the command run:
Call completed.
when i run the program on client side it works fine.
Has anybody tried this from java stroed procedure.
Thanks,
Jag

Jag,
Actually, the question of whether it works for me seems to depend on the version of the OS (or Oracle). On RedHat Linux (Oracle 8.1.6) it didn't work at all, but on Solaris (Oracle 9.0.2) it did. Here's the output from that run:
SQL> /
output of the command run:
init.ora
initDBPart9i.DBPSun01.ora
initdw.ora
lkDBPART9I
orapw
orapwDBPart9i
spfileDBPart9i.ora
Done
PL/SQL procedure successfully completed.
But, I did need to change a line of your code to this:
Process p = Runtime.getRuntime().exec("/usr/bin/ls");
your original was:
Process p = Runtime.getRuntime().exec("ls");
You might consider, if possible, use of some of the Java File classes instead of ls, as this might make things more predictable for you. There were some examples in oramag.com a few months ago, but they were pretty simple (you might not need them).
Hope this helps,

Running sqlplus scripts from Java code?

hi
I need to programmatically run sqlplus scripts from Java code on a machine that doesn't have sqlplus installed.
Is there any Java class library available for doing this?

The Ant approach could probably work for me, thanks for the tip.
The setup seems rather complex however, given the simplicity of the task. I would prefer just running a Java based SQL*Plus from in a separate process or doing this via an API that would allow me to run SQL*Plus scripts (parse script, substitute variables, run statements).
Oracle SQL Developer v1.1 appears to include an API that does exactly this.
The ScriptParser, Substitution and SQLPLUS classes in the oracle.dbtools.raptor.scriptrunner package (oracle.sqldeveloper.jar) seem to do just what I need based on my tests.
Can I use these classes for this purpose in my application? Is repackaging allowed?
Does Oracle have any plans for releasing this sort of functionality separately e.g. as part of the Instant Client?

Running ssh command from java and then answering password prompt

Hi,
I have a situation that has not solved yet. I am running ssh command from unix terminal without any problem, and then i enter password.
For example :
[oracle@fuata]:/export/home/oracle> ssh -N [email protected] -L 9901:127.0.0.1:9999
Password:
It is working. I have question that how can i perform this in java? I am thinking that i can run ssh command by using Runtime Class, it is ok. But how can i answer the password? I am a bit confused. Is there any example looks like this?
Thanks for responses.

Thanx. Firstly i insisted to do this without jsch but actually this is harder than jsch. I edit some of code pieces PortForwardingL.java and could run it. It works problem-free. Could you say why you "insisted" on this approach. It can't be for speed+ since jsch is very fast. It can't be for portability+ since jsch is portable but the use of Runtime.exec() requires the installation of ssh software. It can't be because of limitations+ since jsch is a fully featured library. It can't be for security+ since jsch is secure. It can't be for ease of use+ since jsch is much easier to use than ssh with Runtime.exec(). Unless it's a licensing issue, it can't be for commercial+ reasons since jsch is free. The only reason I can think of why one would "insisted" on this approach is if it is for some college project.

How to run system commands from JAVA

Hi Friends,
How to run windows system commands from JAVA
Runtime r=Runtime.getRuntime();
r.exec("dir");
Throwing following Exception
CreateProcess :dir error=2
Thanks in advance
Hamsa

Hi ,
in Windows NT this is not possible, you can use the following :
Runtime r=Runtime.getRuntime();
StringBuffer sbuf = new StringBuffer();
String dir = new String();
java.lang.Process proc = r.exec("cmd /c dir");
InputStream is = proc.getInputStream();
int ch ;
while((ch=is.read() ) != -1)
sbuf.append((char)ch);
is.close();
dir = sbuf.toString();
System.out.println(dir );

Problem while running dos command from java program

Dear friends,
I need to terminate a running jar file from my java program which is running in the windows os.
For that i have an dos command to find process id of java program and kill by using tskill command.
Command to find process id is,
wmic /output:ProcessList.txt process where "name='java.exe'" get commandline,processid
This command gives the ProcessList.txt file and it contains the processid. I have to read this file to find the processid.
when i execute this command in dos prompt, it gives the processid in the ProcessList.txt file. But when i execute the same command in java program it keeps running mode only.
Code to run this command is,
public class KillProcess {
     public static void main(String args[]) {
          KillProcess kProcess = new KillProcess();
          kProcess.getRunningProcess();
          kProcess = new KillProcess();
          kProcess.readProcessFile();
     public void getRunningProcess() {
          String cmd = "wmic /output:ProcessList.txt process where \"name='java.exe'\" get commandline,processid";
          try {
               Runtime run = Runtime.getRuntime();
               Process process = run.exec(cmd);
               int i = process.waitFor();
               String s = null;
               if(i==0) {
                    BufferedReader stdInput = new BufferedReader(new
                           InputStreamReader(process.getInputStream()));
                    while ((s = stdInput.readLine()) != null) {
                     System.out.println("--> "+s);
               } else {
                    BufferedReader stdError = new BufferedReader(new
                           InputStreamReader(process.getErrorStream()));
                    while ((s = stdError.readLine()) != null) {
                     System.out.println("====> "+ s);
               System.out.println("Running process End....");
          } catch(Exception e) {
               e.printStackTrace();
     public String readProcessFile() {
          System.out.println("Read Process File...");
          File file = null;
          FileInputStream fis = null;
          BufferedReader br = null;
          String pixieLoc = "";
          try {
               file = new File("ProcessList.txt");
               if (file.exists() && file.length() > 0) {
                    fis = new FileInputStream(file);
                    br = new BufferedReader(new InputStreamReader(fis, "UTF-16"));
                    String line;
                    while((line = br.readLine()) != null) {
                         System.out.println(line);
               } else {
                    System.out.println("No such file");
          } catch (Exception e) {
               e.printStackTrace();
          return pixieLoc;
}     when i remove the process.waitFor(), then while reading the ProcessList.txt file, it says "No such file".
if i give process.waitFor(), then it's in running mode and program is not completed.
Colud anyone please tell me how to handle this situation?
or Is there anyother way to kill the one running process in windows from java program?
Thanks in advance,

If i execute the same command in dos prompt,
CommandLine
ProcessId

If i modify the command as,
cmd.exe /C wmic process where "name='java.exe'" get commandline,processid > 123.txt
and keeps in running mode only.
If i open the file when program in running mode, no contents in that file.
If i terminte the program and if i open the file, then i find the processid in that file.
Can you help me to solve this issue?

Running .bat files from java code

Dear Forum,
I have seen numerous postings on the web about this question, still I have found no answer that works (for me)
I�m trying to run a simple .bat file from a piece of java code , however it does not work. No error message , but still.
Does anyone have a tip?
best regards
temuj
try{
String cmd = "cmd.exe C:\\mybat.bat";
Runtime.getRuntime().exec(cmd);
catch(IOException e){System.out.println("ERROR: "+e);}Message was edited by:
temujin

"cmd.exe C:\mybat.bat" is being passed to the OS for execution
what happens when in a terminal/dos window you execute letter for letter:
cmd.exe C:\mybat.bat
The output will be identical to what is happening when java makes this call.

sorry for that , but the
Runtime runtime = Runtime.getRuntime();
          Process proc = runtime.exec(new String[]{"cmd.exe","/c","jar"});
          proc.waitFor();
int i = proc.exitValue();
this code was different from first one
and in case of Process if runtime .exec is succesful it is wainting for long time , in this case i want if the runtime.exec is succesful something should be returned

Running DOS command from JAVA

Hi ,
I would appreciate if anyone could tell me how to run DOS command such as "del" using JAVA language .Thank you.

<steps onto soapbox>
Surely for something like 'del' we should be advocating a non-OS specific method so we don't lose sight of Java's cross platform abilities.
If it has to run an OS specific thing fine, but please look for a non OS specific solution first.
