System Exit from JAVA Application

I need to call Oracle Reports from a JAVA application.
Does anyone have experience in this area?
One thing that comes to mind is to make a system exit and call the reports from the command line. Is this possible to be done? How?
Thank you for any help or suggestions.
Tina.

the best way to access the oracle database is via jdbc (see http://java.sun.com/products/jdbc/ ). if, however, you specifically need to run some oracle reporting s/w then you could run it as a separate process from your java application using Runtime.exec() (see http://java.sun.com/j2se/1.3/docs/api/java/lang/Runtime.html#exec(java.lang.String) ) which returns a Process object. you can then read its output with the Process object's getInputStream() method (this gives you an InputStream which is the data piped from the standard output stream of the process).

    SMS API(WMA) is an optional package. It is not a MIDP1.0 or MIDP2.0 api's.
    There are phones which has WMA api with MIDP1.0 support .... Nokia 3650
    Seimens has some phone with their own api's to send sms.Check out seimens site for more info
    BTW, What do you mean buy sending SMS to Server????

    lite configuration.
    1. In $OLITE_HOME\mobile_oc4j\j2ee\mobileserver\applications
    \mobileserver\setup\common\webtogo\webtogo.ora file edited the JAVA_OPTION
    to:
    JAVA_OPTION=-Djava.compiler=NONE -Dfile.encoding=UTF8
    2. In $OLITE_HOME\mobile_oc4j\j2ee\mobileserver\applications

  • How to call webservice from Java application

    Hi XI gurus
    Pls let me know how to call a webservice from Java application.
    I wanted to build synchronous interface from Java Application to SAP using SAP XI
    For example, i need to create Material master from Java application and the return message from SAP, should be seen in Java application
    Regards
    MD

    Hi,
    If your  JAVA Application is Web based application, you can expose it as Webservice.
    JAVA People will pick the data from Dbase using their application and will send the data to XI by using our XI Details like Message Interface and Data type structure and all.
    So we can Use SOAP Adapter or HTTP in XI..
    If you use HTTP for sending the data to XI means there is no need of Adapter also. why because HTTP sits on ABAP Stack and can directly communicate with the XI Integration Server Directly
    If you are dealing with the Webservice and SAP Applications means check this

    Hi,
    i need to kill or remove windows system process like cmd.exe from java code.
    like removing it from end process in task mgr.
    i tried below code but its not removed.
    is there a better way we can do this.
    killing a system process from java code will create any issues?
       public static void main(String[] args) throws Exception {

       p.destroy();
    any suggestions or ideas are really appreciated.
    thanks.

    Hi  jtahlborn, mohan
    yes the process is created from my java code. 
    in my code iam creating a process like below and if it is running for a long i need to kill it from java.
    For that " Runtime.getRuntime().exec("taskkill /F /PID " +  7408); " is working fine.
    7408 is my process id in taskmgr created from java and iam manually passing the PID it to kill it.
    But i need to get the PID from java code.
    Thanks for your suggestions.
    Sample Code:
    public static void main(String args[])
            try {
              Process process = Runtime.getRuntime().exec(new String[]{"cmd.exe","/c","start"});        
              Field f = process.getClass().getDeclaredField( "handle");
              f.setAccessible( true);         
              long procHandle = f.getLong( process);
              System.out.println( "prochandle: " + procHandle );
              //Runtime.getRuntime().exec("taskkill /F /PID " +  procHandle);

  • How to call javascript from java application

    How can we call a function written in javascript from java application (core java not applet)? How will java identify javascript?
    Is there any such options ?

    Try creating a page called launcher.html (for example). That does this:
    <html>
    <head>
    <script language="javascript">
    windowHandle=window.open("http://www.javasoft.com", "", "height=700,width=1000,status=no,scrollbars=yes,resizable=yes,toolbar=no,menubar=no,location=no,top=5,left=5");
    </script>
    </head>
    </html>Now you launch IE (or whatever) with this page using the Runtime class. After x seconds (after the second window has been launched) try killing the process. Hopefully it will kill the original window you opened and not the window you popup (the one without toolbars etc)
    It might kill both windows but I can't be bothered to test it. If it does you'll have to try and find a workaround.
