Invoking "java myClass" using Runtime.Exec from a Java Stored Procedure

Hi All,
This is regarding the use of Runtime.getRunTime().exec, from a java programme (a Java Stored Procedure), to invoke another Java Class in command prompt.
I have read many threads here where people have been successuful in invoking OS calls, like any .exe file or batch file etc, from withing Java using the Runtime object.
Even i have tried a sample java programme from where i can invoke notepad.exe.
But i want to invoke another command prompt and run a java class, basically in this format:
{"cmd.exe","java myClass"}.
When i run my java programme (in command prompt), it doesnt invoke another command prompt...it just stays hanging.
When i run the java programme from my IDE, VisualCafe, it does open up a command prompt, but doesnt get the second command "java myCLass".
Infact on the title of the command prompt (the blue frame), shows the path of the java.exe of the Visual Cafe.
and anyway, it doesnt run my java class, that i have specified inside the programme.
Even if i try to run a JAR file, it still doesnt do anything.
(the JAR file other wise runs fine when i manually invoke it from the command prompt).
Well, my question is, actually i want to do this from a Java Stored Procedure inside oracle 8.1.7.
My feeling is, since the Java Stored Procedure wont be running from the command prompt (i will be actually invoking it through a Oracle trigger), it may be able to invoke the command prompt and run the java class i want. and that java class has to run with the SUn's Java, not Oracle JAva.
Does any one have any idea about it?
Has anyone ever invoked a java class or JAR file in command prompt from another Java Programme?
YOur help will be highly appreciated.
(P:S- Right now, my database is being upgraded, so i havent actually been able to create a Java Stored procedure and test it. But i have tested from a normal java programme running in command prompt and also from Visual Cafe).
Thanks in advance.

Hello Hari,
Thanks for your quick reply.
Can you please elaborate a little more on exactly how you did? may be just copy an dpaste taht part of teh code here?

  • Can we run a java application using Runtime.exec()?

    Can we run a java application using Runtime.exec()?
    If yes what should i use "java" or "javaw", and which way?
    r.exec("java","xyz.class");

    The best way to run the java application would be to dynamiically load it within the same JVM. Look thru the class "ClassLoader" and the "Class", "Method" etc...clases.
    The problem with exec is that it starts another JVM and moreover you dont have the interface where you can throw the Output directly.(indirectly it can be done by openong InputStreams bala blah............). I found this convenient. I am attaching part of my code for easy refernce.

  • 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?

  • Spawn a java process using runtime.exec() method

    Yes your right. It is proc.getInputStream() or proc.getErrorStream(). That is what I get for trying to use my memory instead of looking it up. Though hopefully the OP would have seen the return type of the other methods and figured it out.

  • Start a new java process using Runtime.Exec() seems to ignore the -Xmx

    I am working with a process that requires a minimum of 1.5 GB to run and works better if more is available.
    So I am determining how much memory is available at startup and restarting the jre by calling
    Runtime.exec("java -Dcom.sun.management.jmxremote=true -Xmx1500M -jar XXX.jar")
    which reinvokes the same process with a new max memory size.
    The initial call to the process is
    java -Dcom.sun.management.jmxremote=true -Xmx3500M -jar XXX.jar
    The initial call returns 3262251008 from Runtime.maxmemory()
    When reinvoked through Runtime.exec() as above
    Runtime.maxmemory() still returns 3262251008
    Is there a way to separate the new process from the size specified by the parent process?

    That is strange. Here is a program I wrote which calls itself recursively.
    import java.io.IOException;

  • Problem of executing a process under Linux using Runtime.exec

    Hi, All
    I am having a problem of executing a process under Linux and looking for help.
    I have a simple C program, which just opens a listening port, accept connection request and receive data. What I did is:
    1. I create a script to start this C program
    2. I write a simple java application using Runtime.exec to execute this script
    I can see this C program is started, and it is doing what it supposed to do, opening a listening port, accepting connection request from client and receiving data from client. But if I stop the Java application, then this C program will die when any incoming data or connection request happens. There is nothing wrong with the C program and the script, because if I manually execute this script, everying works fine.
    I am using jre1.4.2_07 and running under Linux fedora 3.0.
    Then I tried similar thing under Windows XP with service pack2, evrything works OK, the C program doesn't die at all.

    Mind reading is not an exact science but I bet that you are not processing either the process stdout or the stderr stream properly. Have you read http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html ?

    ??First of all, you're not even calling the Happy Holiday one. If you want it to do something, you have to invoke it.
    And by the way, in your comments, you mention that in one case, a new process is created. Actually, new processes are created each time you call Runtime.exec.
    Anyway, if you want the output from the processes, you read it using getInputStream from the Process class. In fact, you really should read that stream anyway (read that URL I sent you to find out why).
    If you want to print that output to the screen, then do so as you'd print anything to the screen.
    in notepad HelloWorld.java, I can see it is opened,
    but in Java, not.I have no idea what you're saying here. It's not relevant whether a source code file is opened in Notepad, when running a program.

  • Launching another Swing application from existing one using Runtime.exec()

    Hi,
    I have two separate Swing applications, say A and B. I need to launch B from A using Runtime.exec() - essentially I am launching another VM instance from one VM. I am encountering strange problems - B's main window comes up, but GUI doesn't update; sometimes B comes up and GUI updates, but huge memory leaks happen. All the problems with B go away once A is shut down. It almost looks like both the instances of VM are sharing (or competing for) the event thread. Any comments will be of great help. Thanks.
    note: There is no problem launching B if A is a console java application (i.e. no Swing GUI).

    Do you have to have the second application running in a seperate VM (process)? If not completely neccesary, then you can just invoke the static main() of the second class. If the type of the second class isn't known untill run-time, you can use Reflection to invoke the method.

  • Parameter  to shell script using Runtime.exec(string)

    Hi all, ( Speciall hi to dheeraj tak )
    Briefly : How do i pass an arguement to a non - java executible being called using Runtime.exec.
    In detail : i am using Runtime.exec to call a shell script : The code is as follows:
    String callAndArgs[] = {"/home/tom/jakarta-tomcat-4.1.24/webapps/dash/script.sh"};
    try {
    Runtime rt = Runtime.getRuntime();
    Process child = rt.exec(callAndArgs);
    This works properly & calls the shell script which in turn invokes some other executible (c file).
    $HOME/midi/test/build/bin/<C-EXECUTIBLE>
    Here i am specifying the name (say hello.exe ) . So far so good.
    I want to make this happen dynamiclaly. so i need to pass the name of the executible as a parameter to the script.
    To pass a parameter i hav to change the string to :-
    String callAndArgs[] = {"/home/tom/jakarta-tomcat-4.1.24/webapps/dash/script.sh <C-EXECUTIBLE HERE>"};
    and the script to
    $HOME/midi/test/build/bin/$1 --- where $1 refers to argument 1. (C-EXECUTIBLE AGAIN).
    This is giving an IO - Execption. Plz help
    Code will be very helpful.
    Thanx in advance

    some 1 plz tell me the difference :-
    This is the documentation of Runtime.exec that i found :-
    1> exec
    public Process exec(String command) throws IOException
    Executes the specified string command in a separate process.
    The command argument is parsed into tokens and then executed as a command in a separate process. This method has exactly the same effect as exec(command, null).
    Parameters:
    command - a specified system command
    Complete refernce says : Process (String progName) ----- Executes a program specified by programname as a seperate process.
    2> exec
    public Process exec(String cmdarray[]) throws IOException
    Executes the specified command and arguments in a separate process.
    The command specified by the tokens in cmdarray is executed as a command in a separate process. This has exactly the same effect as exec(cmdarray, null).
    Parameters:
    cmdarray - array containing the command to call and its arguments.
    Complete reference says : Process exec(String comLineArray[]) ---- Executes the command line specified bythe string in comLineArray as a seperate process.
    This means that there is provision 4 command line arguments...

  • Using Runtime.exec to execute a C++ executable

    Hello,
    I would like to know if it possible to execute a C++ executable using Runtime.exec() and wait for it to complete and how do I read back the output file created by the C++ executable into the Java Code?
    TIA.
    RHP

    When I execute the code with Runtime.exec(), and read
    from the Process's inputStream I am ablt to view the
    cout from the C++ code. But the output file that has
    to be created by the C++ code is not created,Then this is maybe an error in the C++ code? Maybe you don't have permissions to create that file where you want to.
    where
    would the output from the C++ code go to when I use a
    ofstream in my C++ code andIf you create the file stream in C++ with an absolute file name then the output goes into that file. If it's a relative file name, then the basis is most likely the current working directory (found in the system property "user.dir" if you used one of Runtime's methods without the File argument, otherwise it's the directory you provide.
    How do I read both streams
    from the Java Code?You create an FileInputStream and - if you want to read character instead of binary data - on top of that an InputStreamReader. You might add a BufferedReader on top of that if you want to read line by line.
    does that answer your questions?

  • Using runtime.exec to zip some files

    Hi,
    I am using runtime.exec to try to automatically zip a bunch of files on a server. However, it does not seem to be working.
    Before I execute the command, I save the zip command in a string. I then print the string to a log file, and then execute the runtime zip command. But nothing happens.
    Yet, when I copy the string from the log, and paste it in a terminal, it properly creates the zip files. So, I know I have the correct command string, it just does not seem to be working within the java application. Also, the command string uses fully qualified directories, so it is not a directory issue.
    I am using ubuntu linux.
    Any ideas?

Within Runtime.exec() any command does not run in a shell and I bet you use wild cards and/or other commands to be interpreted by a shell which will not be interpreted since there is no shell. And, since you don't mention error messages or the return code, I will also bet you don't process the Process stdout , stderr and the return code properly.

    note: There is no problem launching B if A is a console java application (i.e. no Swing GUI).

    I have recently had the same problem, especially with the part where it seems like the two applications are sharing or competing for the same event thread. Sometimes my application B hangs like it is stuck waiting for an event. Sometimes I can get it to unhang by moving the app window around or minimizing it. If it does break free, all the queued events occur in rapid succession. Anybody have any clue what's going on here? It's pretty annoying.
