Excute unix script from java.

Hi need to excute unix script from java application.
My code is:
public class Test
public static void main(String args[])
try{
p = Runtime.getRuntime().exec("./qfe0"); //qfe0 is the name of the script.
p.waitFor();
catch(Exception e)
e.printStackTrace();
My problem is that using the waitFor() statement stuck the the script. if i don't use the waitFor() it works good but then i don't know when the script is finished.
Any idea?

The problem is likely to be that you script is either waiting for input or has filled the stdout buffer and you are not emptying it. Search this forum for this as its been answered many times before.

Problem calling two perl modules from java in seperate threads(JVM CRASHES)

Dear Friends,
I have one severe problem regarding calling perl modules from java
I had to call two perl modules simultaneously (i.e.) from two threads,,, but jvm crashes when one of the perl calls is exiting earlier
I am unable to spot out why ....
For calling perl from java ...., We are first calling C code from java using JNI and then Perl code from C
All works fine if we call only one perl call at a time.... If we call them in a synchronized manner the JVM is not crashing .... But we don't want blocking..

what els I have to do.Well, what have you tried?
You need the Oracle JDBC driver jar (ojdbc14.jar) which you can download from Oracle or somewhere I believe....I can't remember where I got it. Anyway, google for the Oracle JDBC driver and you should find it.
You will probably need to read up on JDBC as I can't believe you even did that before you realised you needed a driver to connect. Good luck.

Call an interactive UNIX command from java

Hi,
I want to call a UNIX command from java. When issue the command 'htpasswd -c filename username' on UNIX terminal, it asks for the new password and the then confirmation password again (yeah, unfortunately the htpasswd installed on our system does not allow you proivde the password on the command line. So have to work interactively ). Now, I have written a simple java program RunCommand.java. I am hardcoding the password for the htpasswd command in the file (in the real situation, password will be generated dynamically). I want to issue 'java RunCommand' on the UNIX command line and get back the command prompt without being asked for the password twice. The code is below, but the Outputstream does not work as expected. It always asks for inputs. Any idea? Many thanks.
import java.io.*;
public class RunCommand {
public static void main(String args[]) throws Exception {
String s = null;
try {
String cmd = "htpasswd -c filename username ";
// run a Unix command
Process p = Runtime.getRuntime().exec(cmd);
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
OutputStream stdOut = p.getOutputStream();
String pswd = "mypassword";
while ((s = stdInput.readLine()) != null) {
     s = stdInput.readLine();
     stdOut.write(pswd.getBytes());
     stdOut.flush();
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
stdOut.close();
stdInput.close();
stdError.close();
System.exit(0);
catch (IOException e) {
System.out.println("exceptions caught: ");
e.printStackTrace();
System.exit(-1);

Execute unix commands from Java

Hi,
I have a client application running on windows. This client should connect to a unix server and check for the existence of a file and display the result as "File found/File not found". In order to connect from windows to the unix server, I used the sockets and the connection is successfully established. The second part is to check for the presence of the file in unix server. I searched in google.com and the option I found to execute a unix command from java is the "Runtime.exec()". Runtime.exec is considered as the less effective (not a favorable) one.
Is there any other option available (other than the Runtime) to execute the unix command from java? Can you please let me know.
Thanks a lot
Aishu

So, please let me know how I can execute the above unix commands without Runtime.exec()You have a client and a server.
You want something to run on the server, not the client.
That means that something must in fact being running on the server before the client does anything at all.
For example telnet. Or a J2EE server application.
So is something like that running?
If not then there absolutely no way to do what you want, even with Runtime.exec().
If yes then what you do depends on what is running. So Runtime.exec() would be pointless if a J2EE server was running.

Run a UNIX Script from java

Hi,
how can i run a unix script from java application. This java application is on windows.
How can i do this.
thanks,

Hi,
how can i run a unix script from java application.
This java application is on windows.
So I think it's safe to assume that the target script is on a remote unix server.
Take a look at http://sourceforge.net/projects/sshtools/

How execute Unix script from java?

Can I execute Unix script from java?

Yes. Using ProcessBuilder. And read [When Runtime.exec() wont|http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html]. It's old, but pretty much all of it is still true.

Problem executing Unix script from Java...

Hi there, I'm having trouble executing a unix script from a java program. The script receives multiple parameters and it seems that one of them ( or more ) is not well interpreted. When I run the script directly from a shell, the script executes without any errors. But, when I run the exact same script with the exact same parameters, it does not work.
Here is the command to execute the script with all the parameters that is executed from the shell ( with success ) and also from the java program ( with errors ):
/z/opus/dcap/intfu001.csh 'NODEBUG^NOTKPROF^NOSTACK' opus dcap JACQUES JACQUES '2625781' 'ORA$PIPE$001D00D70001' JOB^DEBUG^SINISIMU^STATPROD^DECTIDANC^81^503^4080^86^87^151^97^98^99 BUT^N^N^SPRI^0^13^24^3^J^05^N^19^19^19 >> /tmp/switcher8.999.null.pgm.test
And here is my portion of code that executes the script:
Runtime wShell = Runtime.getRuntime();
Process wProc = wShell.exec(cmd_unix_final);
wProc.waitFor();
return wProc.exitValue();
Please give me your thoughts on this!
Thanks in advance!

Ok.
Let's proceed surgically, else we'll never solve or overcome anything.
In the last your reply you wrote:
the normal output is what I get when the script runs successfully, the script first prints a few things
and then does stuff that takes at least 2 or 3 secondsWhat do you mean?
-Finally have you got your script correctly executed?
The stuffs you spoke of are really performed?
If this is the case I can't see the prob.
Is your concern only about exitValue() for it doesn't let you distinguish programmatically
the success or failure of the script execution?
Of course you surely already have a routine in your java code to handle
exceptional situations of errors from the script.
And the "normal output" is just what you must parse to detect those errors.
Then who cares about exitValue() in this case?
Don't invoke it, relay on the stdout and stderr of the script.
-Or you get only a deceiving standard output
that let you think the script execution went alright, while instead it didn't.
In this case we have to investigate some other thing.
I can't still exclude that the problem isn't related with the buffer size of the stdout
allocated by the environment to the subprocess. You spoke of few things printed out.
Be explicit. What's the size of the output you get?
And is the "normal output" complete till the very last char
or is it truncated from somewhere on?
Also it's important that you hit a ps command after the java main process terminates
(or simply when waitFor() returns) and see if the script subprocess hung up.
As an alternative approach directly call your pro*C code from Java through JNI, instead of translating it.
1. Exec.java
public class Exec{
     static{
          System.loadLibrary("Exec");

Invoking unix executable from java

How do I capture the RETURN VALUE from the Unix process (executable) invoked from java program

After using Runtime.getRuntime() , and using runtime.exec(ProcessName), You get a Process object you can use waitFor() method of process. After that call process.getInputStream() and encapsulate in DataInputStream then onwards u can use readLine method to get value it is returned.

Problems with running quote server from Java Tutorial

Hello
The problem is this: I try to run QuoteServer from java tutorial (Trail: Deployment
Lesson: Applets, A Simple Network Client Applet) and server compiles but when I try to run it following message shows up:
QuoteServer listening on port: 32769
Exception in thread "QuoteServer" java.lang.NullPointerException
at java.net.DatagramPacket.setData(DatagramPacket.java:244)
at java.net.DatagramPacket.<init>(DatagramPacket.java:62)
at java.net.DatagramPacket.<init>(DatagramPacket.java:78)
at QuoteServerThread.run(QuoteServerThread.java:38)
And then server stops. What's going on?.
Cheers

Line 38 of QuoteServer.java is: packet = new DatagramPacket(buf, 256);
And that's where the problem is because in line 31 is written byte[] buf = null;
And what I get when I run QuoteServer.java with gcj version of java (gives more clues) is:
java QuoteServer
QuoteServer listening on port: 32785
Exception in thread "QuoteServer" java.lang.NullPointerException: Null buffer
at java.net.DatagramPacket.setData(byte[], int, int) (/usr/lib/libgcj.so.6.0.0)
at java.net.DatagramPacket.DatagramPacket(byte[], int, int) (/usr/lib/libgcj.so.6.0.0)

at QuoteServerThread.run() (Unknown Source)
at .GC_start_routine (/usr/lib/libgcj.so.6.0.0)
at .__clone (/lib/libc-2.3.5.so)
So the problem is with this null buffer. What enter in line 31 instead of null?.
What values can byte[] reach except null?. I tried to find byte[] in java API but there is only Byte variable. I get the same output with java 5.0 compiler (but less clues).

Need to access/connect Remote Unix server from Java

Please any one give me a direct solution for connecting a remote Unix server through telnet connection from java application. Thanks in advance..

If I run the below program codes, in the console it is asking to enter username and password in manual but I need to give it automatically.
The highlighted "root" is entered by the user manually using keyboard.
Expected:
I mean the username, password and some action is set to be automatic, so that it should not ask the user to enter the input from keyboard.
