Need Simple Executable program

Hi
I'm not an ABAPer .so, please help me in this task... I want to write an executable program in taht i just call an BAPI (BAPI_COMPANY_GETDETAIL ) and for this BAPI i want to pass the COMPANY ID . and RFC destionation are the input parameters...
because if i execute this BAPI menas.. the output of this BAPI i want to send it to external system.. that configuration is done... only thing is.. how can we pass those RFC destiona and COMPANYID as inputs to the bapi..
if possible please give me the solution
Thanks
Babu

Hi,
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access. Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.
The following standardized BAPIs are provided:
Reading instances of SAP business objects
GetList ( ) With the BAPI GetList you can select a range of object key values, for example, company codes and material numbers.
The BAPI GetList() is a class method.
GetDetail() With the BAPI GetDetail() the details of an instance of a business object type are retrieved and returned to the calling program. The instance is identified via its key. The BAPI GetDetail() is an instance method. BAPIs that can create, change or delete instances of a business object type
The following BAPIs of the same object type have to be programmed so that they can be called several times within one transaction. For example, if, after sales order 1 has been created, a second sales order 2 is created in the same transaction, the second BAPI call must not affect the consistency of the sales order 2. After completing the transaction with a COMMIT WORK, both the orders are saved consistently in the database.
Create( ) and CreateFromData! ( )
The BAPIs Create() and CreateFromData() create an instance of an SAP business object type, for example, a purchase order. These BAPIs are class methods.
Change( )
The BAPI Change() changes an existing instance of an SAP business object type, for example, a purchase order. The BAPI Change () is an instance method.
Delete( ) and Undelete( ) The BAPI Delete() deletes an instance of an SAP business object type from the database or sets a deletion flag.
The BAPI Undelete() removes a deletion flag. These BAPIs are instance methods.
Cancel ( ) Unlike the BAPI Delete(), the BAPI Cancel() cancels an instance of a business object type. The instance to be cancelled remains in the database and an additional instance is created and this is the one that is actually canceled. The Cancel() BAPI is an instance method.
Add<subobject> ( ) and Remove<subobject> ( ) The BAPI Add<subobject> adds a subobject to an existing object inst! ance and the BAPI and Remove<subobject> removes a subobject from an object instance. These BAPIs are instance methods.

Bdc to Bapi
The steps to be followed are :
1. Find out the relevant BAPI (BAPI_SALESORDER_CHANGE for VA02).
for VA01 use BAPI_SALESORDER_CREATEFROMDAT2
2. Create a Z program and call the BAPi (same as a Funtion module call).
2. Now, if you see this BAPi, it has
-> Importing structures.
eg: SALESDOCUMENT: this will take the Sales order header data as input.
-> Tables parameters:
eg: ORDER_ITEM_IN: this will take the line item data as input.
Note :
Only specify fields that should be changed
Select these fields by entering an X in the checkboxes
Enter a U in the UPDATEFLAG field
Always specify key fields when changing the data, including in the checkboxes
The configuration is an exception here. If this needs to be changed, you need to complete it again fully.
Maintain quantities and dates in the schedule line data
Possible UPDATEFLAGS:
U = change
D = delete
I = add
Example
1. Delete the whole order
2. Delete order items
3. Change the order
4. Change the configuration
Notes
1. Minimum entry:
You must enter the order number in the SALESDOCUMENT structure.
You must always enter key fields for changes.
You must always specify the update indicator in the ORDER_HEADER_INX.
2. Commit control:
The BAPI does not run a database Commit, which means that the application must trigger the Commit so that the changes are read to the database. To do this, use the BAPI_TRANSACTION_COMMIT BAPI.
For further details... refer to the Function Module documentation for the BAPi.
Bapi to VB(Visual Basic)
Long back I had used the following flow structure to acheive the same.
Report -> SM59 RFC destination -> COM4ABAP -> VB.exe
my report uses the rfc destination to create a COM session with com4abap. com4abap calls the vb.exe and manages the flow of data between sap and vb exe.
You need to have com4abap.exe
If com4abap is installed you will find it in sapgui installatin directory , C:\Program Files\SAPpc\sapgui\RFCSDK\com4abap.
else refer OSS note 419822 for installation of com4abap
after making the settings in com4abap to point to the vb program and setting up rfc destination in sm59 to point to com4abap session , you can use the following function modules to call the vb code.
for setting up com4abap and rfc destination please refer to the documentation for com4abap.
Invoke NEW DCOM session
call function 'BEGIN_COM_SESSION'
exporting
service_dest = service_dest "(this will be a RFC destination created in SM59)
importing
worker_dest = worker_dest
exceptions
connect_to_dcom_service_failed = 1
connect_to_dcom_worker_failed = 2
others = 3.
call function 'create_com_instance' destination worker_dest
exporting
clsid = g_c_clsid
typelib = g_c_typelib
importing
instid = g_f_oid
exceptions
communication_failure = 1 message g_f_msg
system_failure = 2 message g_f_msg
invalid_instance_id = 3
others = 4.
call function 'com_invoke' destination worker_dest

%return = g_t_pdfdetail1 "t_test
exceptions
communication_failure = 1 message g_f_msg
system_failure = 2 message g_f_msg
invalid_instance_id = 3
others = 4.
then close the com session , using
FM delete_com_instance
FM END_COM_SESSION

Need simple sample program

I need a very SIMPLE application that does the following so I can see the logic/syntax and put it in the program I am writing:
1. Has a GUI
2. has one text field with ActionListener implemented
3. computes the squares of one through ten and sends the results to a text file
4. sends results to a text file whose name is gotten from the text field
For example: I would type "asdf" (without the quoatation marks) in the text field , then press enter/return. The program would then send the results of the math operation to a text file named "asdf."

A simple Java program to be compiled with ojc and executed with java.exe

Hi ,
This thread is relevant to Oracle Java Compiler (file ojc) and jave.exe file.
I have written a simple java program which consists of two simple simple classes and using the JDev's 10.1.3.2 ojc and java files , i'm trying to execute it after the successful compilation....
The problem is that trying to run it... the error :
Exception in thread "main" java.lang.NoClassDefFoundError: EmployeeTest
appears.
How can i solve this problem...????
The program is as follows:
import java.util.*;
import corejava.*;
public class EmployeeTest
{ public static void main(String[] args)
   { Employee[] staff = new Employee[3];
      staff[0] = new Employee("Harry Hacker", 35000,
         new Day(1989,10,1));
      staff[1] = new Employee("Carl Cracker", 75000,
         new Day(1987,12,15));
      staff[2] = new Employee("Tony Tester", 38000,
         new Day(1990,3,15));
      int i;
      for (i = 0; i < 3; i++) staff.raiseSalary(5);
for (i = 0; i < 3; i++) staff[i].print();
class Employee
{ public Employee(String n, double s, Day d)
{ name = n;
salary = s;
hireDay = d;
public void print()
{ System.out.println(name + "...." + salary + "...."
+ hireYear());
public void raiseSalary(double byPercent)
{ salary *= 1 + byPercent / 100;
public int hireYear()
{ return hireDay.getYear();
private String name;
private double salary;
private Day hireDay;
For compilation... i use :
D:\ORACLE_UNZIPPED\JDeveloper_10.1.3.2\jdev\bin\ojc -classpath D:\E-Book\Java\Sun_Java_Book_I\Corejava EmployeeTest.java
For execution , i issue the command:
D:\ORACLE_UNZIPPED\JDeveloper_10.1.3.2\jdk\bin\java EmployeeTest
NOTE:I tried to use the jdk of Oracle database v.2 but the error :
Unable to initialize JVM appeared....
Thanks , a lot
Simon

Hi,
Thanks god....
I found a solution without using Jdev.....
C:\oracle_files\Java\Examples>SET CLASSPATH=.;D:\E-Book\Java\Sun_Java_Book_I\Corejava
C:\oracle_files\Java\Examples>D:\ORACLE_UNZIPPED\JDeveloper_10.1.3.2\jdk\bin\javac EmployeeTest.java
C:\oracle_files\Java\Examples>D:\ORACLE_UNZIPPED\JDeveloper_10.1.3.2\jdk\bin\java EmployeeTest
What does Ant has to do with this?Sorry, under the Ant tree a classpath label is found....I'm very new to Java and JDev...
You need to include the jar file that has the Day method in it inside project properties->libraries.I have not .jar file.. just some .java files under the corejava directory.... By the way , I have inserted the corejava directory to the project pressing the button Add Jar/Directory.... , but the problem insists..
Thanks , a lot

"Assertion failed" error when executing a simple UCI program

I am using a simple UCI program (tt1.c) with Xmath version 7.0.1 on Sloaris 2.8 that performs the followings:
- Start Xmath701
- Sleep 10 Seconds
- Load a sysbuild model
- Stop Xmath
I am calling the uci executable using the following command:

I tracked down the problem and it is a race condition between the many processes being started up. A smaller delay should also solve the problem. Or, maybe do something else before the first 'load'. The 'load' command tries to launch systembuild and causes the race condition.

I need ready code for a simple paint program today

hi all I need ready code for a simple paint program today for me ics projct
plz give me a halp on this give me what you have with you and it is so good if it look like this :
Design a GUI based drawing Java application that works like a simple paint program
1-There should be a number of buttons for choosing different shapes to draw. For example, there should be a button for rectangle. If user presses the rectangle button, then he can draw a rectangle using mouse. Similarly, there should be a button for each shape(rectangle, circle, ellipse, and line etc.
2-The shapes can be filled with different colors.
3-There should be option of moving .
4- There should also be three menus including File, Shape, and Color menu.
i. File menu can have menu items New and Exit. If user selects New, the drawing area will be cleared and all shapes will be erased.
ii. Shape menu will serve the same purpose as of feature 2 described above. It will have menu items for drawing all the different shapes. For example, there will be menu item for rectangle; so user can draw a rectangle by selecting the menu item for rectangle.
iii. Color menu will serve the same purpose as of feature 3 described above. It will have menu items for all the colors which are shown in color buttons. The user can select a color from this menu and then click inside a shape to fill it with the selected color.

Read the Swing tutorial. There are sections on how to use menus and painting and all other kinds of stuff you need to do this homework assignment. Nobody here is going to write the code for you:

Need help on with simple email program

i have been set a task to create a simple email program that has the variables of the sender the recipient the subject the content and a date object representing when the email was sent (this is just to be set to the current system date)
It also needs to include a constructor with four String arguments, i.e the sender, receiver, subject and content. The constructor has to initialise the date of the email then transfer the values of the input parameters to the relevant attributes. If any values of the strings aren'nt given, the string �Unknown� should be set as the value.
I was given a java file to test the one i am to create, but some of the values are not given, if anyone could be of anyhelp or just point me in the right direction then i would be very greatfull, ive posted the code for the test file i have been given below, thanks.
public class SimpleEmailTest {
     public static void main( String[] args ) {
          SimpleEmail email;     // email object to test.
          String whoFrom;          // sender
          String whoTo;          // recipient
          String subject;          // subject matter
          String content;          // text content of email
          static final String notKnown = "Unknown";
          email = new SimpleEmail
(notKnown, notKnown, notKnown, notKnown);
          System.out.println( "SimpleEmail: " +
"\n    From: " + email.getSender() +
"\n      To: " + email.getRecipient() +
"\n Subject: " + email.getSubject() +
"\n    Date: " +
email.getDate().toString() +
"\n Message: \n" + email.getContent() + "\n";
          email.setSender( "Jimmy Testsender");
          email.setRecipient( "Sheena Receiver");
          email.setSubject( "How are you today?");
          email.setContent( "I just wrote an email class!");
          System.out.println( "SimpleEmail: " +
"\n    From: " + email.getSender() +
"\n      To: " + email.getRecipient() +
"\n Subject: " + email.getSubject() +
"\n    Date: " +
email.getDate().toString() +
"\n Message: \n" + email.getContent() + "\n";
     }

Start by writing a class named SimpleEmail, implement a constructor with four arguments in it, and the methods that the test code calls, such as the get...() and set...() methods. The class probably needs four member variables too.
public class SimpleEmail {
    // ... add member variables here
    // constructor
    public SimpleEmail(String whoFrom, String whoTo, String subject, String content) {
        // ... add code to the constructor here
    // ... add get...() and set...() methods here
}

Need to execute tcl script from a Java Program

Hello,
I need to execute a tcl script from a Java Program. But I do not know how to call the tcl Interpreter. Can anybody help me?

Process proc =
rt.exec("C:/SpirentConnect/engines/tcl/8.3.4/windows/s
ctcl.exe C:/Hello.tcl");
But Hello.tcl is not executed.And does that exact string work on the command line?
And what is the return code from running it?

Need Help with Simple Chat Program

Hello Guys,
I'm fairly new to Java and I have a quick question regarding a simple chat program in java. My problem is that I have a simple chat program that runs from its own JFrame etc. Most of you are probably familiar with the code below, i got it from one of my java books. In any case, what I'm attempting to do is integrate this chat pane into a gui that i have created. I attempted to call an instace of the Client class from my gui program so that I can use the textfield and textarea contained in my app, but it will not allow me to do it. Would I need to integrate this code into the code for my Gui class. I have a simple program that contains chat and a game. The code for the Client is listed below.
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import javax.swing.*;
public class Client
extends JPanel {
public static void main(String[] args) throws IOException {
String name = args[0];
String host = args[1];
int port = Integer.parseInt(args[2]);
final Socket s = new Socket(host, port);
final Client c = new Client(name, s);
JFrame f = new JFrame("Client : " + name);
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we) {
c.shutDown();
System.exit(0);
f.setSize(300, 300);
f.setLocation(100, 100);
f.setContentPane(c);
f.setVisible(true);
private String mName;
private JTextArea mOutputArea;
private JTextField mInputField;
private PrintWriter mOut;
public Client(final String name, Socket s)
throws IOException {
mName = name;
createUI();
wireNetwork(s);
wireEvents();
public void shutDown() {
mOut.println("");
mOut.close();
protected void createUI() {
setLayout(new BorderLayout());
mOutputArea = new JTextArea();
mOutputArea.setLineWrap(true);
mOutputArea.setEditable(false);
add(new JScrollPane(mOutputArea), BorderLayout.CENTER);
mInputField = new JTextField(20);
JPanel controls = new JPanel();
controls.add(mInputField);
add(controls, BorderLayout.SOUTH);
mInputField.requestFocus();
protected void wireNetwork(Socket s) throws IOException {
mOut = new PrintWriter(s.getOutputStream(), true);
final String eol = System.getProperty("line.separator");
new Listener(s.getInputStream()) {
public void processLine(String line) {
mOutputArea.append(line + eol);
mOutputArea.setCaretPosition(
mOutputArea.getDocument().getLength());
protected void wireEvents() {
mInputField.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
String line = mInputField.getText();
if (line.length() == 0) return;
mOut.println(mName + " : " + line);
mInputField.setText("");

Thanks for ur help!i have moved BufferedReader outside the loop. I dont think i am getting exception as i can c the output once.What i am trying to do is repeat the process which i m getting once.What my method does is first one sends the packet to multicasting group (UDP) and other method receives the packets and prints.

Executing a simple assembly program using legion

How do I execute a simple assembly program using Legion simulator and view the registers?

I tracked down the problem and it is a race condition between the many processes being started up. A smaller delay should also solve the problem. Or, maybe do something else before the first 'load'. The 'load' command tries to launch systembuild and causes the race condition.

Need to execute a sub-VI continuously, while others are executed on demand.

I'm running into a problem while trying to develop a set of controls for a scanning probe microscope. I have a PID control which governs the height of the probe above the sample (feedback input is through a PCI DAQ card), and which needs to run at all times. I also have a scan control which raster-scans the area of interest as defined in the input. Both of these programs work fine on their own. the problem I am encountering is: due to the nature of the position control equipment, these controls must be consolidated into a single VI (the "device handle" can only be called in one program at a time). The PID needs to execute constantly and in real time, while the scan needs to execute only on command. is there a relatively simple way to call a sub-VI such that it will run continuously at a high priority, while allowing another to be called on demand? Specifically, I need to avoid either sub-VI becoming caught in a "while" or "case" structure and refusing to allow the other to execute.

I suppose I should have included a bit more information in my original post.
I am running under windows XP, the PID updates once per millisecond via analog voltage reading, the instrument can queue commands but there's no current need to do so as the speed with which I need to issue commands is significantly below the USB polling rate.
also, the problem with execution in parallel is that while the VI's are effectively independent, they both need to receive the same device ID from the controlling DLL. Unfortunately, the device ID command can't be called separately in each VI due to hardware restrictions, which is the reason I was looking for some sort of background execution option.
I'm attaching the VI's themselves to make the situation a bit more clear as well.
thanks for your input.

How to restrict rights of executed program

Greetings,
I need to execute JAVA programs (student homework), where there is not guaranteed that one of the submission is some kind of trojan horse, which could potentially e.g. delete some important files on a machine, which executes the code.
Is there any simple way how to restrict rights of executed program?
Or how does e.g. tomcat hosting provider guarantee the security?
Thanks in advance.

Simple OO program question

Hi there,
I would like to start writing some programs for myself now that I know a good part of the syntax of Java to keep learning in an intereseting way.
But I have the problem that I still don't realy own the OO thinking to start a project.
For example; I would like to write - to begin simple - a program that can add notes through a textfield and show the notes in a list or something like that.
Also I would like to be able to save and load my notes list when I close and open the program respectively.
I had thought of the following classes to use:
- Main (for executing the program and calling the gui)
- NotesGui (the actual window and swing components)
- Note (a domain class representing a note with some attributes and methods)
Is this a good idea? Or has somebody a better suggestion to start writing this little program?
Help would be very appreciated ^^
Thanks,
Gert-Jan M.

I am in a similar boat. I am new to Java and OO programming in general. For the record, I am using Java: How to Program as my book. The reason why I mention this will be clear. In my opinion you need to do a few things to get this project started. I myself and trying to think of a project to do in order to increase my skills. My opinion:
In the book I am using, they have an ATM case study where they go through the complete process of creating an application. Their process follows a standard software development life cyle. What I can get from it so far is that the starting point is Requirements gathering. You need to write out in some detail what it is that you want your application to do. This shouldn't necessarily state the how or what technologies will be used. Once they have the requirements defined, they begin identifying potential classes from within the requirements document. I believe there are many ways to do this but in general they select all the nouns in the requirements document and start formulating their list where it makes sense. They also use UML and other tools to create class diagrams, use cases etc that help explain the interaction objects will have with one another. A lot of the upfront work is gathering requirements and desinging much of what you want to do prior to even coding. Since I'm new to this I'm sure other, more experienced developers could expand on this.
My point is that you will want to understand the software development lifecycle and process, and learn more about software design. My personal end goal is to start learning design patterns and software development methodologies once I have a firm understanding of the Java language. Recommended readings could include the Deitel book Java: How to Program, Head First Object Oriented Analysis and Design, Head First Software Development and Head First Design Patterns. The Head First series seems nice because, in a somewhat easy fashion, they help explain software development processes, testing, software design, requirements gathering techniques and more. I think the sooner a developer learns about good design the better. I hope this helps.

I'm not able to run a simple Hello Program in java

I have just now installed jdk 1.3.1_2.
I have set the path and class path.
I'm able to compile the class without any errors but am not able to run the program.
when i say java Hello(after compiling Hello.java), i'm seeing the following error:
Exception in thread "main" java.lang.NoclassDefFoundError:Hello
Thanks in advance in this regard

Hmm..
Okay.. set aside any import or package stuffs.. lets say about a simple HelloWorld program which is called Hello.class. It resides in c:\, which means the full path is c:\Hello.class.
Make sure you got one of your path as c:\jdk1.3\bin(assuming you are using jdk 1.3).
If you are in the same directory as Hello.class, which is c:\>, you can execute the class file by typing:
C:\>java Hello
If you are not in the same directory and you wishes to run the class file, example you are in directory temp now:
C:\Temp>java -cp C:\ Hello
So the cp set will be just c:\. Hope that answers your question somehow.. well... if I never intepret it wrongly.
