  • How to Call .XDO file From Java Program

    Hi,
    I have developed a report in using BI Publisher version 10.1.3.
    I created the report and it only created XDO files. If I want to call XDO file from Java program how I can do that.
    What are the APIs available to do that.
    Thanks
    -Ashutosh

    Hi,
    the JavaAPI didn't work with the xdo-Files. But you can create a proxy stub for the Web Service API of BI Publisher which uses the xdo's in the repository.

  • .exe file from java

    Hi all !!!
    Is it possible to run a *.exe file from java.....
    if yes how??
    if no why not??
    regards
    ad

    Yes. It's possible. One of the Runtime.exec() methods are probably what you want:
    http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html
    You can't instantiate a Runtime object, so you'll need to call it up by:
    Runtime.getRuntime()
    For example, if you want to run the Calculator in Windows, try:
    Runtime.getRuntime().exec("calc");

  • Running exe files from java applications

    Hello All,
    Is it possible to run executable files from java applications?
    I need to run an exe file on the client from the server machine, the exe could reside on either the server or any other machine on the LAN. Is it possible to specify the path of where the exe resides, and run it on a client machine?

    HI,
    I tried to launch a MS Word application using runtime.exec but it gives me some problem
    The foll. code to launch a txt file using notepad works.
    Runtime rt = Runtime.getRuntime();
    String[] callAndArgs = {"notepad.exe","C:\\coo7\\wizard.txt"};
    Process child = rt.exec(callAndArgs);
    However, oif I try to launch a MS Word application, it asks for the entire path of WINWORD.exe, (unlike just specifying notepad.exe as the first argument in String[] callAndArgs) and this can vary from one machine to another.. how do I get around this?
    The foll. code snippet works but the complete path of where WINWORD.exe might be installed on any machine, is not fixed:-(
    Runtime rt = Runtime.getRuntime();
    String[] callAndArgs = {"C:\\Program Files\\Office\\Office10\\WINWORD.exe","C:\\coo7\\wizard.doc"};
    Process child = rt.exec(callAndArgs);
    Any idea/suggestions pls..

  • Calling a function in an EXE file from Java Program

    Hi Im having a function which is written in c program.i need to call that function from my java program, if i create a shared library (DLL) for my C code then it works but my requirement is i dont want to create that DLL , like in it would be an executable and my java code should access that function in that C program

    I understand the usage od a DLL but the thing is if i convert the exe to a DLL
    the server doesnt start at all so what i need is that i dont want to change
    that .EXE into a .DLL,let it be an executable. that executable is in running mode
    and through my java program i need to call a function in that EXE file.
    Is ther any way to do it?Nope, but you have another problem: why can't you separate your server program
    into a .dll part and a startup part? Both, when properly linked against each other
    should give you an executable file.
    kind regards,
    Jos

  • Running .EXE file from Java

    Do you know, how run an .exe file, for example Internet Explorer or other program, from Java application?
    It's very important for me.

    Too run external program and pass string arguments see class java doc
    of java.lang.Runtime method exec . You see online or download or
    rename src.jar to s.zip EXTRACT and see
    exec
    public Process exec(String[] cmdarray,
    String[] envp)
    throws IOException
    Executes the specified command and arguments in a separate process with the
    specified environment.
    This is a convenience method. An invocation of the form exec(cmdarray, envp)
    behaves in exactly the same way as the invocation exec(cmdarray, envp,
    null).
    Parameters:
    cmdarray - array containing the command to call and its arguments.
    envp - array of strings, each element of which has environment variable
    settings in the format name=value, or null if the subprocess should inherit
    the environment of the current process.
    Returns:
    A new Process object for managing the subprocess
    Throws:
    SecurityException - If a security manager exists and its checkExec method
    doesn't allow creation of the subprocess
    IOException - If an I/O error occurs
    NullPointerException - If cmdarray is null, or one of the elements of
    cmdarray is null, or one of the elements of envp is null
    IndexOutOfBoundsException - If cmdarray is an empty array (has length 0)
    See Also:
    ProcessBuilder
    getRuntime
    public static Runtime getRuntime()
    Returns the runtime object associated with the current Java application.
    Most of the methods of class Runtime are instance methods and must be
    invoked with respect to the current runtime object.
    Returns:
    the Runtime object associated with the current Java application.
