How do I get the return value from an executable?

I'm running an external executable from dbms_scheduler but how do I get the exit code from the program run or any screen output?

Hi,
In the additional_info column of schedulerjob_run_details there should be something like
job of type EXECUTABLE failed with exit code: Operation not permitted
"Operation not permitted" is the error code (as translated by the errors header file for that platform).
In releases 10.2 and up there may also be a line in the additional_info
STANDARD_ERROR="Error text here"
This gives the standard error messages output by the application. There is no way to get the standard output of the application.
Hope this helps,
Ravi.

Hi,
What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.

How can i get the all values from the Property file to Hashtable?

how can i get the all values from the Property file to Hashtable?
ok,consider my property file name is pro.PROPERTIES
and it contain
8326=sun developer
4306=sun java developer
3943=java developer
how can i get the all keys & values from the pro.PROPERTIES to hashtable
plz help guys..............

The Properties class is already a subclass of Hashtable. So if you have a Properties object, you already have a Hashtable. So all you need to do is the first part of that:Properties props = new Properties();
InputStream is = new FileInputStream("tivoli.properties");
props.load(is);

Remote Object - not able to get the returned value from java method

     Hi ,
I am developing one sample flex aplication that connects to the java code and displays the returned value from the
java method in flex client. Here I am able to invoke the java method but not able to collect the returned value.
lastResult is giving null . I am able to see the sysout messages in server console.
I am using flex 3.2 and blazeds server and java 1.5
Here is the code what I have written.
<?xml version="1.0" encoding="utf-8"?><mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#FFFFFF" initialize="initApp()">

     public String setName(){          System.
out.println("Name changed in Java");
          return "Name changed in Java";
And I have configured destination in remote-config.xml
<destination id="sro">
   <properties>
    <source>SimpleRemoteObject</source>
    <scope>application</scope>
   </properties>
</destination>
Please help me .

You are not able to get the returned value because if you see the Remote object help you will realise you have to use result="resultfn()" and fault = "faultfn()"
In this you define what you wish to do.
More importantly in the remote object you need to define which method you wish to call using the method class like this
<mx:RemoteObject id="remoteObj" destination="sro" result="r1" fault="f1" >
     <Method name="javaMethodName" result="r2" fault="f2"/>
<mx:RemoteObject>
r2 is the function where you get the result back from java and can use it to send the alert.

How can I get the edited value from the editor in JTable

I have a JTextField added as an editor to a cell in JTable.
I value gets changed when I press enter.
but in actionPerformed of the JTextField when I say
String txtEditorValue = txtEditor.getText();
I am getting the old value. How can I get the edited value? Thanks.

Hi,
I guess, your understanding of how JTable works together with its models is not good enough - for example the method getTableCellEditorComponent(...) of the TableCellEditor interface is used to get the component, that should be used as editing component - its second parameter is a value that should be used to setup the editing component - it is normally not the editing component itself.
JTable uses an underlying TableModel to store the cell values - if you have edited a cell, JTable gets the value of the editing component by itself and stores it in the TableModel using its setValueAt(...) method. To retrieve this data you only need to query the TableModel using row and column of this cell as parameters
say jt is your JTable, and row and column are the row and column of the cell - so to get the value, simply use
Object obj = jt.getModel().getValueAt(row,column);
if you know, that there is a String in this cell use
String str = (String) jt.getModel().getValueAt(row,column);
The editor component is used for the view of the JTable - you only want the data, which is stored in the model - you don't have to deal with the GUI components in this case.

How to get the returned value from Functions with Callable statement?

I was glad to find that stored procedures can be invoke with Java class code by the object of Callable statement like :
String stmt = "BEGIN departments_pkg.do_select(?,?,?); END;";
and getting the output variables by
populateAttribute(DEPARTMENTNAME,st.getString(2),true,false);
But i would like to get values returned from FUNCTION other than stored procedure, how can i achieve it? Thanks a lot!

Here is my code
PROCESS BEFORE OUTPUT.
MODULE STATUS_1202.
MODULE subscreen_find.
CALL SUBSCREEN SUBSEARCH INCLUDING sy-cprog dynnr.
PROCESS AFTER INPUT.
MODULE USER_COMMAND_1202.
CALL SUBSCREEN SUBSEARCH.
MODULE subscreen_find.
case sy-ucomm.
    when 'SELECTED'.             "fcode
      case 'ZSKILL_SEARCH'.     "data element
        when '01'.                       " value range
          dynnr = 0110.
        when '02'.
          dynnr = 0111.
      endcase.
endcase.
ENDMODULE.

How can I get the cursor value from a waveform graph

Is there a way to get the value of cursor position on the waveform graph so mathematical calculations be performed on those values. We can see the value in cursor legend, but can we extract those values for future calculations in the block diagram somehow.

Right-click on the waveform graph icon. Select Create>Property Node>Cursor>Cursor Position. That spits out a a xy cluster for the current cursor position.
If you have more than one cursor, you can either set up a loop and set the Active Cursor property node (right click the property node and select "Change to Write") or you can pull everything you ever wanted to know about every cursor with the Cursor List property node.

How do I get the returned cursor from a stored procedure to an asp.

Sorry if this topic has been answered before but I am new to Oracle and ASP. I have been asked to create some stored procedures and access the results from the ASP. I will be passing one variable in and could be getting upto 200 rows returned.
I have no trouble with the stored procedure but have no clue how to retrieve the data returned by it.

Assuming that the stored procedure has a single argument, an OUT cursor, you should be able to do
SQLExecDirect
{call <stored_proc>() }
SQLFetch
SQLGetData
We'll handle all the 'magic' underneath.

How to return 2 value to a method and how can i get the return value?

hi guys, this is my problem.
private void one(){
two();
private Vector, Vector two(){
return(row, column);
the problem is that I don't know how to call the two() method and return from two() to one().
please help me, i'm very new to programming........
liml

the problem is that I don't know how to call the two()
method and return from two() to one()You can doprivate Vector[] two () {
    return new Vector[] {
        row,
        column
} // as suggested
private void one () {
    Vector[] rowAndColumn = two ();
    Vector row = rowAndColumn[0];
    Vector column = rowAndColumn[1];
}You should consider replacing your Vector with an ArrayList, btw.
Kind regards,

Getter/setter methods -- how do I use the return values

I'm just learning Java, and I haven't been to this site since the end of July, I think. I have a question regarding getter and setter methods. I switched to the book Head First Java after a poster here recommended it. I'm only about a hundred pages into the book, so the code I'm submitting here reflects that. It's the beginnings of a program I'd eventually like to complete that will take the entered information of my CD's and alphabetize them according to whatever criteria I (or any user for that matter) choose. I realize that this is just the very beginning, and I don't expect to have the complete program completed any time soon -- it's my long term goal, but I thought I could take what I'm learning in the book and put it to practical use as I go along (or at lest try to).
Yes I could have this already done it Excel, but where's the fun and challenge in that? :) Here's the code:
// This program allows the user to enter CD information - Artist name, album title, and year of release -- and then organizes it according the the user's choice according to the user's criteria -- either by artist name, then title, then year of release, or by any other order according to the user's choice.
//First, the class CDList is created, along with the necessary variables.
class CDList{
     private String artistName;//only one string for the artist name -- including spaces.
     private String albumTitle;//only one string the title name -- including spaces.
     private int yearOfRelease;
     private String recordLabel;
     public void setArtistName(String artist){
     artistName = artist;
     public void setAlbumTitle(String album){
     albumTitle = album;
     public void setYearOfRelease(int yor){
     yearOfRelease = yor;
     public void setLabel(String label){
     recordLabel = label;
     public String getArtistName(){
     return artistName;
     public String getAlbumTitle(){
     return albumTitle;
     public int getYearOfRelease(){
     return yearOfRelease;
    public String getLabel(){
    return recordLabel;
void printout () {
       System.out.println ("Artist Name: " + getArtistName());
       System.out.println ("Album Title: " + getAlbumTitle());
       System.out.println ("Year of Release: " + getYearOfRelease());
       System.out.println ("Record Label: " + getLabel());
       System.out.println ();
import static java.lang.System.out;
import java.util.Scanner;
class CDListTestDrive {
     public static void main( String[] args ) {
          Scanner s=new Scanner(System.in);
          CDList[] Record = new CDList[4];
          int x=0;
          while (x<4) {
          Record[x]=new CDList();
          out.println ("Artist Name: ");
          String artist = s.nextLine();
          Record[x].setArtistName(artist);
          out.println ("Album Title: ");
          String album = s.nextLine();
          Record[x].setAlbumTitle(album);
          out.println ("Year of Release: ");
          int yor= s.nextInt();
                s.nextLine();
          Record[x].setYearOfRelease(yor);
          out.println ("Record Label: ");
          String label = s.nextLine();
          Record[x].setLabel(label);
          System.out.println();
          x=x+1;//moves to next CDList object;
          x=0;
          while (x<4) {
          Record[x].getArtistName();
          Record[x].getAlbumTitle();
          Record[x].getYearOfRelease();
          Record[x].getLabel();
          Record[x].printout();
          x=x+1;
               out.println("Enter a Record Number: ");
               x=s.nextInt();
               x=x-1;
               Record[x].getArtistName();
            Record[x].getAlbumTitle();
            Record[x].getYearOfRelease();
            Record[x].getLabel();
            Record[x].printout();
     }//end main
}//end class          First, I'd like to ask anyone out there to see if I could have written this any more efficiently, with the understanding that I'm only one hundred pages into the book, and I've only gotten as far as getter and setter methods, instance variables, objects and methods. The scanner feature I got from another book, but I abandoned it in favor of HFJ.
Secondly --
I'm confused about getter and setter methods -- I'd like someone to explain to me what they are used for exactly and the difference between the two. I have a general idea, that getters get a result from the method and setters set or maybe assign a value to variable. I submitted this code on another site, and one of the responders told me I wasn't using the returned values from the getter methods (he also told me about using a constructor method, but I haven't got that far in the book yet.). The program compiles and runs fine, but I can't seem to figure out how I'm not using the returned values from the getter methods. Please help and if you can explain in 'beginners terms,' with any code examples you think are appropriate. It will be greatly appreciated.
By the way, I'm not a professional programmer -- I'm learning Java because of the intellectual exercise and the fun of it. So please keep that in mind as well.

But this is something every new programmer goes through, and I will not spoil the fun. You see, in 3 to 6 months when you have learned much more Java, assuming you stick with it, you will look back at this and be like "what the hell was I thinking" and then realize just haw far you have come. So enjoy that moment and don't spoil it now by asking for what could have been better/ more efficient. If it works it works, just be happy it works.

So please keep that in mind as well.First, if you posted this somewhere else you should link to that post, it is good you at least said you did, but doubleposting is considered very rude because what inevitably happens in many cases is the responses are weighed against each other. So you are basically setting anyone up who responds to the post for a trap that could make them look bad when you double post.
You are setting you getters and setters up right as far as I can tell. Which tells me that I think you grasp that a getter lets another class get the variables data, and a setter lets another class set the data. One thing, be sure to use the full variable name so you should have setRecordLabel() and getRecodLabel() as opposed to setLabel() and getLabel(). Think about what happens if you go back and add a label field to the CDList class, bad things the way you have it currently. Sometimes shortcuts are not your friend.
And yes, you are using the getters all wrong since you are not saving off what they return, frankly I am suprised it compiles. It works because you don't really need to use the getters where you have them since the CDList Record (should be lowercase R by the way) object already knows the data and uses it in the printout() method. Basically what you are doing in lines like:
Record[x].getArtistName();is asking for the ArtistName in Record[x] and then getting the name and just dropping it on the floor. You need to store it in something if you want to keep it, like:
String artistName = Record[x].getArtistName();See how that works?
Hope this helped, keep up the good learning and good luck.

How to Sort by the length of the returned value from a query.

Hi,
I was wondering if it is possible to sort by the length of the returned value from a query?
For example if I want to get a list of people with the name 'Samuel', I would like to short by how short the length of the whole name is.
Sort by length of the name in SQL
Samuel Syda
Samuel Indranaka
Samuel Johnsons
Samuel Longhenderson
Thank you.

Hi,
Sorting is done by an ORDER BY clause at the end of the main query.
In most cases, you can ORDER BY any expression, even f it is not in the SELECT clause. In this case, it sounds like you just need:
ORDER BY LENGTH (name_column)
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Post your query, using an ORDER BY clause like the one above, and point out where that query is producing the wrong results, and explain, using specific examples, how you get the right results from the given data in those places.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).
