How to get return value from Java runtime.getRuntime.exec?

I'm running shell commands from an Oracle db (11gr2) on aix.
But, I would like to get a return value from a shell comand... like you get with "echo $?"
I use a code like
CREATE OR REPLACE JAVA SOURCE NAMED common."Host" AS
import java.io.*;
public class Host {
  public static int executeCommand(String command) {
    int retval=0;
    try {
        String[] finalCommand;
        finalCommand = new String[3];
        finalCommand[0] = "/bin/sh";
        finalCommand[1] = "-c";
        finalCommand[2] = command;
      final Process pr = Runtime.getRuntime().exec(finalCommand);
      pr.waitFor();
   catch (Exception ex) {
      System.out.println(ex.getLocalizedMessage());
      retval=-1;
    return retval;
/but I do not get a return value... because I don't know how to get return value..

Hi,
Have your tried pr.exitValue() ?
I think you also need a finally block that destroys the subprocess

  • How to get return value from java and read by other application?

    i want to read return value from java and the other application read it.
    for example:
    public class test_return {
        test_return(){
        public int check(){
            return 1;
        public static void main(String args[]){
           new test_return().check();
    }from that class i make as jar file. How to read the return value (1) by other application?
    thx..

    If your installer is requiring some process it invokes to return a particular value on failure, then the installer is seriously broken. There are a bazillion commands your installer could invoke, and any of them could fail, which in turn could invalidate the entire install process, and any of them could return any value on failure. The only value that's consistent (in my experience) is that zero means success and non-zero means failure, with specific non-zero values being different in different programs.
    About the only control you have over the JVM's exit code is that if your main method completes without throwing an exception, the JVM will have an exit code of 0, and if main throws an exception (either explicitly or by not catching one thrown from below), it will be non-zero. I'm not even sure if that's guaranteed, but I would guess that's the case.
    EDIT: I'm kind of full of crap here. If you're writing the Java code, you can call System.exit(whatever). But nonetheless, if your installer requires certain exit codes from any app--java or otherwise--you have a problem.

  • How to get return values from task flow in af:region ?

    Hi!
    I'm working with a taskFlow that is rendered inside a popup using the "popup inside a region pattern" (http://www.oracle.com/technology/products/adf/patterns/popupregionpattern.pdf), but now this taskFlow has an input parameter and a return value definition. So the question is how to get a value returned by this taskFlow thas is called inside a region?
    Any suggestion?
    Thanks in advance!

    Hi,
    write the value to a shared memory scope like session and read it in the regionNavigation listener. If you follow the paper you refer to then the listener determines of the viewId is null, this a return happens. It wuld then look in the memory scope for the return value.
    Another option would be to use an object that you pass as an argument to the task flow you open in the popup. Then you change the object you passed in, which then makes the return information available in teh calling flow. The object you pass in would have to be in a shared scope too

    You need to have either OUTPUT parameters or use RETURN statement to return a value in stored procedures. RETURN can only return integer values whereas OUTPUT parameters can be of any type
    First modify your procedure to define return value or OUTPUT parameter based on requirement
    for details see
    http://www.sqlteam.com/article/stored-procedures-returning-data
    Once that is done in SSIS call sp from Execute SQL Task and in parameter mapping tabe shown above add required parameters and map them to variables created in SSIS and select Direction as Output or Return Value based on what option you used in your
    procedure.

  • How to get return values from region?

    I add a page flow as region into a page. The page flow has a return parameter. How to get the return value in parent page?

    I have been also intrigued by this question.
    There is however a workaround that you can set the values in requestScope.
    We can have a regionNavigationListener on the region and catch the end of taskflow if viewid is null.
    regionNavigationEvent.getNewViewId() == null
    Here we can read the request values and set wherever to be used.

    //need code here for enabling table
    if(s=="mactus") If you don't know how to correctly test for String equality, you will have no chance of getting this to work.
    You need to hit the tutorials. First the basic one, then the Swing one.

    DataItem dataItem = fm.getFocusedControl().getDataItem();
    ImmediateAccess col_code = null;
    String code = null;

    } catch (ColumnNotFoundException ce) {
    return;
    } catch (SQLException se) {
    return;
    JTextField tf = new JtextField();
    tf.setText(code);
    I haven't tested this code.
    I am curious to know, the Object type of the dataItem.If it doesnot happen to be RowsetAccess ..try.. ScrollableRowsetAccess OR ImmediateAccess.
    Your code would change accordingly, depending on the instance.Refer to the product documentation for this.

  • How to get string value from xml in JSF??

    In JSF How to get string value from xml, .ini and properties file. I want to get string value from xml or text to JSF

    Just use the appropriate API's for that. There are enough API's out which can read/parse/write XML, ini and properties files. E.g. JAXP or DOM4J for xml files, INI4J for ini files and Sun's own java.util.Properties for propertiesfiles.
    JSF supports properties files as message bundle and resource bundle so that you can use them for error messages and/or localization.

    Hi Kranthi,
    Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.
