This article explains how to execute shell commands from whitin pl/sql using java (in the database).

It is for Oracle8i but should still work. This still looks like a good way to go.

  • How to call OS Commands through PL/SQL ?

    Is there any package to call OS (Solaris) commands from PL/SQL ? I want to do who cammand within PL/SQl Stored Proc and get the output inserted into a table. How can I do this ?

    Why don't you want to use Java? There are certainly alternatives, but without knowing why you don't like the Java solution, it's rather hard to know whether those alternatives make any sense in your environment.
    - You can make an external procedure call to a DLL (or shared library) installed on the server
    - You could use AQ or potentially DBMS_PIPE to communicate with external applications
    - You could use UTL_TCP to interact over the network with a machine
    - You may have other options depending on specifics about the call you're trying to make and the software you have.
    - In 10g, you could use the DBMS_SCHEDULER package to call OS commands

  • How to execute MS DOS command through Java program???

    Dear Sir,
    I want to run a MS-DOS command through my Java program. I have tried "Dir" command but no other command which takes command line args doesn't work at all. Please help.
    import java.io.*;
    class CommandPrompt
         public static void main(String[] args)
              try
                   File file = new File("C:/Temp/Java");
                   String[] cmd = {"command.com","/c","md folder"};
                   String[] envp = {""};
                   Process m;
                   String s = "";
                   m = Runtime.getRuntime().exec(cmd,null,file);
                   BufferedReader buf = new BufferedReader(new InputStreamReader(m.getInputStream()));
                   while ((s = buf.readLine())!=null)
                        System.out.println(s);
              catch (Exception ex)
                   System.out.println("Exception is "+ex);
                   ex.printStackTrace();

    1. This forum is for Swing-related issues only. This question should be posted to the "Java Programming" forum.
    2. Please enclose your sample code in code blocks; it's much easier to read that way. See here for how it's done: http://forum.java.sun.com/faq.jsp#messageformat
    3. Please provide more information, like what error messages you got and what OS you're running. For instance, if you're running WinXP, Win2k or NT4, your command processor should be "cmd.exe", not "command.com". When I made that change, your program worked for me.

  • How to execute dos command in Java program?

    In Perl, it has System(command) to call dos command.
    Does java have this thing?
    or any other way to execute dos command in java program?
    Because i must call javacto compile a file when the user inputed a java file name.

    Look in the Runtime class, it is implemented using the Singleton design pattern so you have to use the static method getRuntime to get its only instance, on that instance you can invoke methods like
    exec(String command) that will execute that command in a dos shell.

    Hi,
    You are running a jsp report through rwservlet. In this case paper layout will be displayed. You have to deploy your jsp as web report to get the web layout. Please refer to the doc below, which describes how to deploy the web report.
    http://download-uk.oracle.com/docs/html/B10314_01/pbr_run.htm#1011901
    To run the jsp report, URL may look like
    http://www.wwt.com/reports/<jsp name>?<parameter list>

  • How to call gnuplot command from java

    Hi there,
    In our course, we are required to develop an GUI for gnuplot. In case you don't know about gnuplot, it's a plotting program and has lots of command. We want to use java and swing, but now we don't know how to call gnuplot command from java, or how to execute a shell command(script) from java.
    By the way, since we need read in files with several columns of data and allow user to select a column, we want to use JTable. Is that reasonable?
    Thanks a lot for any suggestions!
    Jack

    Hi, there:
    Will using JTable add much overhead? I may have to use several JTables and switch among them. I can add scroll bar to or edit JTables, right?
    BTW, do you have experience about gnuplot? Can I find the command tree of gnuplot somewhere? Or do you know a better place to post question about gnuplot? unix/linux group, maybe.
    Thanks,
    Jack
    P.S. Would you guys answer my question after I use up my duke dollars? :- )

  • What is the best way to call SSH commands through Java technologies

    What is the best way to call SSH commands through Java technologies

    I don't think you can specify the password at the prompt using ssh. Plink has the -pw command option for passwords. What I did was except ssh to ask me and write the password programmatically through the outputStream I obtained from my Process object. I looked for "password: ", and then wrote the password with a trailing newline.
    Both plink and ssh will also ask if you trust the host if it is the first time you are connecting to it. So before just writing the password, check if the program wants verification from you: normally supplying "y" or "n". This should only have to happen the first time the client connects. It looks like thisPLINK:
    The server's host key is not cached in the registry. You
    have no guarantee that the server is the computer you
    think it is.
    The server's key fingerprint is:
    1024 f8:43:61:4c:a2:5b:77:be:5b:a7:bb:1f:f7:79:b3:b7
    If you trust this host, enter "y" to add the key to
    PuTTY's cache and carry on connecting.
    If you want to carry on connecting just once, without
    adding the key to the cache, enter "n".
    If you do not trust this host, press Return to abandon the
    connection.
    Store key in cache? (y/n)
    SSH:
    The authenticity of host '127.0.0.1 (127.0.0.1)' can't be established.
    RSA key fingerprint is e1:02:13:c8:52:c2:23:41:9b:5b:58:2c:18:e6:59:af.
    Are you sure you want to continue connecting (yes/no)?What I did was read character by character from the inputStream until I found things of interest ... like "password: ". You only need to search for this in your method which will launch the ssh or plink Process. Once you have verifyed yourself, you can just pass commands to the Process, which is an ssh connection.
    My suggestion is to read() each byte from the Process's inputStream and write it to stdout. Look and see what you need to be looking for so you can interactive with the program correctly. You can't use readLine here becuase when the ssh asks for the password it does not print a newline. I do know for sure, that ssh will simply print, "passowrd: ". Plink will print this as well if the -pw option is not supplied.

    If you do the redirect with javascript, the user cannot resubmit his login when he presses the refresh button. When he does press refresh, he only refreshes the redirect, not the form post that was before it. When he presses back the redirect will also kick him back in stead of going back to the login page. A simple javascript redirect page would look like this:
    <html>
    <body onload="document.location.href='myhtmlpage.htm';">
    </body>
    </html>But that is only if you care about resubmits of course.
