WD4Abap and EP 6.o
Hello,
I'm new to WD4Abap and I have a question: Is it possible to integrate a WD4Abap (WAS 7.0) application into a Enterprise Portal 6.0 with WebDynpro IView for Abap?
Thanks in advance,
Thomas
Thanks for your answers!
I need to integrate the application as WDA IView, because I want to read the user id of the logged in portal user (like described in [this|User ID; thread).
I'll give you more details:
I have a WDA application. The authentication to the SAP system is configured with a service user. So the enduser has no user in the sap system.
Nevertheless I need the information, which user is logged on the portal. In [this|User ID; thread I found a way to do that.
I understood that, this works only with a WDA IView. I think, with URL IView I can't use this.
Does somebody know, if the combination EP 6.0 and WDA application with WDA IView works?
Regards,
Thomas

Possibilities Web Dynpro for ABAP versus JAVA
Hello,
I would like to know whether WebDynpro for ABAP and Java have the same options, abilities and possibilities. e'm I able to produce the same results with WebDynpro for ABAP as Java. I would like to standardize on just one of the two and be sure that it will to limit me later.
Thanks in advance.Hi Maurice,
If you make have to make a choice you have to consider the followings:
- Which release do you have? Java version is available since 6.30/6.40, the ABAP only as of 7.00.
- Performance. If you have your WD4ABAP and backend (eg ERP) in the same system you gain a lot of performance
- Other small difference, that Java version has a much nicer graphical editor, which I miss from the ABAP version
These are, which came to my mind.
Best regards,

Dear all,
I know this is an already discussed topic and I found some useful stuff around this.
But I'm thinking more in the direction where we have restriction in case we go one the other way. What I got so far is that we have to go with Java in case we would like to develop stuff for mobile devices. So Java is a must for mobile devices.
What about ADS (adobe document servces) could this be used from both languages?
HCM (Birth of a child) to change the standard ... Java or ABAP?
many thanksHi Maurice,

Hi,
I'm trying to wrting to the nested node in the context but I can't.
I have the following context:
root
pai (1..n) singleton
filho(1..n) singleton
I'm tryng to do a master/detail application.
The node pai is bound to a table in my view, the node filho is bound to another. My objective is to show the detail (node filho) correct to each line in table master.
I can write to node pai, it works. I wrote to the node filho too, but when I debug, only one element of node child is filled.
If someone could help me, I would be thankfull.
The complete code is here, I put it into the wd_doinit of my view:
data: table_pai type wd_this->elements_pai,
table_pai_linha type wd_this->element_pai,
passo type matnr,
lo_nd_pai type ref to if_wd_context_node,
lo_nd_filho type ref to if_wd_context_node,
lo_el_filho type ref to if_wd_context_element,
table_filho_linha type wd_this->element_filho,
lo_el_pai type ref to if_wd_context_element,
cont type integer.
passo = '123456789012345678'.
do.
table_pai_linha-matnr = passo.
append table_pai_linha to table_pai.
passo = passo + 1.
if passo = '123456789012345683'.
exit.
endif.
enddo.
lo_nd_pai = wd_context->get_child_node( 'PAI ').
lo_nd_pai->bind_table( new_items = table_pai set_initial_elements = abap_false ).
cont = lo_nd_pai->get_element_count( ).
do.
lo_nd_pai->SET_LEAD_SELECTION_index( cont ).
lo_el_pai = lo_nd_pai->get_element( ).
lo_nd_filho = lo_el_pai->get_child_node( wd_this->wdctx_filho ).
lo_el_filho = lo_nd_filho->create_element( ).
lo_nd_pai->get_attribute( exporting name = 'matnr' importing value = passo ).
table_filho_linha-matnr_filho = passo.
lo_el_filho->set_static_attributes(
exporting
static_attributes = table_filho_linha ).
lo_nd_filho->bind_element( new_item = lo_el_filho set_initial_elements = abap_false ).
cont = cont - 1.
if cont = 0.
exit.
endif.
enddo.
thanks,Yogesh,
I read the article.
So, If I set the node "filho" as singleton I can't fill this node with elements for all elements of node "pai".
The elements will be lost. It is that I don't understand, if the elements will be lost, there are no reason to use singleton, I can't imagine when I could use this option.
If I want to fill all the context in one time, I have to set the node as non-singleton.
Is all that I said correct?
sorry for the quantity of questions, but I'm new in WD4Abap and I want to learn very much.
Thanks a lot -
Dynamic table data not transfered to context WD4ABAP
Hello Guys,
Currently I have a urgent problem with Adobe Forms and WD4Abap. We are using AdobeReader 8.1.1 und Designer 7.1. Me problem is:
1) I have an interactive form with dynamic table and simple fields...
2) Data within textfields can be updated, created and deleted
3) Data which is initially transfered to TABLES can be changed!!!
4) BUT, if I add or delete a table row, this is NOT sent back to the WebDynpro context
I am using the buttons out of the WebDynpro Navtiv Library. Furthermore, if I save the PDF on my Harddisk and start in manually (offline) add, change or delete data, the data is updated by checking it with the export data function within Adobe reader (Document->Form->Export Data)
Is anybody able to help me, my ideas are on the end...
Best
CarstenHi Carsten,
Thanks again for your quick response.
I tried using the code you supplied (changing the appopriate fieldnames to suit my form) but unfortunately I am still not able to access the added rows from my WD context.
Could you please clarify a couple of things for me?
1. In the following line, is "button_1a_+" the name of your button that adds new rows?
> Carsten Sallaba wrote:
>
>$record.BEHAVIOR.PARAMETER.value = "button_1a_+";
2. I presume that the following line in the code snippet should trigger the submit event on the WD, however this doesn't seem to be working for me, even after creating an action for the onSubmit event in the WD. Do you have any further info on the changes that need to be made on the WD side?

A problem with Threads and loops.
Hi, I have some code that needs to be constantly running, like while(true)
//code here
}However, the code just checks to see if the user has input anything (and then if the user has, it goes to do some other stuff) so I don't need it constantly running and hogging up 98% of the CPU. So I made my class (which has the method that needs to be looped, call it ClassA) implement Runnable. Then I just added the method which needed to be looped into the public void run()
I have another class which creates an instance of the above class (call it ClassB), and the main(String[] args) is in there.
public static void main(String[] args)
ClassA test = new ClassA();
Thread thread = new Thread(test.getInstanceOfClassA());
thread.start();
while(true)
//I do not know what to put here
try
thread.sleep(100);
catch(InterruptedException iex)
}However, the thread only calls run() once,(duh...) but I can't think of away to get it to run - sleep - run -sleep forever. Can someone help me?Hi, I have some code that needs to be constantly
running, like while(true)
//code here
}However, the code just checks to see if the user has
input anything (and then if the user has, it goes to
do some other stuff) so I don't need it constantly
running and hogging up 98% of the CPU. Where does the user input come from. Are you reading from an InputStream? If so, then your loop will be blocked anyway when reading from the InputStream until data is available. During that time, the loop will not consume processor cycles.
public static void main(String[] args)
ClassA test = new ClassA();
Thread thread = new Thread(test.getInstanceOfClassA());I have never seen this idiom. If ClassA instanceof Runnable, you simply write new Thread(test).
thread.start();
while(true)
//I do not know what to put
do not know what to put here
try
thread.sleep(100);
catch(InterruptedException iex)
}However, the thread only calls run() once,(duh...)Yeah, why would you want to call it more than once given that you have an infinite loop in ClassA.run()?

A problem with Threads and MMapi
I am tring to execute a class based on Game canvas.
The problem begin when I try to Play both a MIDI tone and to run an infinit Thread loop.
The MIDI tone "Stammers".
How to over come the problem?
Thanks in advance
Kobi
See Code example below:
import java.io.IOException;
import java.io.InputStream;
import javax.microedition.lcdui.Graphics;
import javax.microedition.lcdui.Image;
import javax.microedition.lcdui.game.GameCanvas;
import javax.microedition.media.Manager;
import javax.microedition.media.MediaException;
import javax.microedition.media.Player;
public class MainScreenCanvas extends GameCanvas implements Runnable {
private MainMIDlet parent;
private boolean mTrucking = false;
Image imgBackgound = null;
int imgBackgoundX = 0, imgBackgoundY = 0;
Player player;
public MainScreenCanvas(MainMIDlet parent)
super(true);
this.parent = parent;
try
imgBackgound = Image.createImage("/images/area03_bkg0.png");
imgBackgoundX = this.getWidth() - imgBackgound.getWidth();
imgBackgoundY = this.getHeight() - imgBackgound.getHeight();
catch(Exception e)
System.out.println(e.getMessage());
* starts thread
public void start()
mTrucking = true;
Thread t = new Thread(this);
t.start();
* stops thread
public void stop()
mTrucking = false;
public void play()
try
InputStream is = getClass().getResourceAsStream("/sounds/scale.mid");
player = Manager.createPlayer(is, "audio/midi");
player.setLoopCount(-1);
player.prefetch();
player.start();
catch(Exception e)
System.out.println(e.getMessage());
public void run()
Graphics g = getGraphics();
play();
while (true)
tick();
input();
render(g);
* responsible for object movements
private void tick()
* response to key input
private void input()
int keyStates = getKeyStates();
if ((keyStates & LEFT_PRESSED) != 0)
imgBackgoundX++;
if (imgBackgoundX > 0)
imgBackgoundX = 0;
if ((keyStates & RIGHT_PRESSED) != 0)
imgBackgoundX--;
if (imgBackgoundX < this.getWidth() - imgBackgound.getWidth())
imgBackgoundX = this.getWidth() - imgBackgound.getWidth();
* Responsible for the drawing
* @param g
private void render(Graphics g)
g.drawImage(imgBackgound, imgBackgoundX, imgBackgoundY, Graphics.TOP | Graphics.LEFT);
this.flushGraphics();
}You can also try to provide a greater Priority to your player thread so that it gains the CPU time when ever it needs it and don't harm the playback.
However a loop in a Thread and that to an infinite loop is one kind of very bad programming, 'cuz the loop eats up most of your CPU time which in turn adds up more delays of the execution of other tasks (just as in your case it is the playback). By witting codes bit efficiently and planning out the architectural execution flow of the app before start writing the code helps solve these kind of issues.
You can go through [this simple tutorial|http://oreilly.com/catalog/expjava/excerpt/index.html] about Basics of Java and Threads to know more about threads.

N.B. And yes there are more articles and tutorials available but much of them targets the Java SE / EE, but if you want to read them here is [another great one straight from SUN|http://java.sun.com/docs/books/tutorial/essential/concurrency/index.html] .

Problem with Threads and a static variable
I have a problem with the code below. I am yet to make sure that I understand the problem. Correct me if I am wrong please.
Code functionality:
A timer calls SetState every second. It sets the state and sets boolean variable "changed" to true. Then notifies a main process thread to check if the state changed to send a message.
The problem as far I understand is:
Assume the timer Thread calls SetState twice before the main process Thread runs. As a result, "changed" is set to true twice. However, since the main process is blocked twice during the two calls to SetState, when it runs it would have the two SetState timer threads blocked on its synchronized body. It will pass the first one, send the message and set "changed" to false since it was true. Now, it will pass the second thread, but here is the problem, "changed" is already set to false. As a result, it won't send the message even though it is supposed to.
Would you please let me know if my understanding is correct? If so, what would you propose to resolve the problem? Should I call wait some other or should I notify in a different way?
Thanks,
B.D.
Code:
private static volatile boolean bChanged = false;
private static Thread objMainProcess;
protected static void Init(){
objMainProcess = new Thread() {
public void run() {
while( objMainProcess == Thread.currentThread() ) {
GetState();
objMainProcess.setDaemon( true );
objMainProcess.start();
public static void initStatusTimer(){
if(objTimer == null)
objTimer = new javax.swing.Timer( 1000, new java.awt.event.ActionListener(){
public void actionPerformed( java.awt.event.ActionEvent evt){
SetState();
private static void SetState(){
if( objMainProcess == null ) return;
synchronized( objMainProcess ) {
bChanged = true;
try{
objMainProcess.notify();
}catch( IllegalMonitorStateException e ) {}
private static boolean GetState() {
if( objMainProcess == null ) return false;
synchronized( objMainProcess ) {
if( bChanged) {
SendMessage();
bChanged = false;
return true;
try {
objMainProcess.wait();
}catch( InterruptedException e ) {}
return false;
}Thanks DrClap for your reply. Everything you said is right. It is not easy to make them alternate since SetState() could be called from different places where the state could be anything else but a status message. Like a GREETING message for example. It is a handshaking message but not a status message.
Again as you said, There is a reason I can't call sendMessage() inside setState().
The only way I was able to do it is by having a counter of the number of notifies that have been called. Every time notify() is called a counter is incremented. Now instead of just checking if "changed" flag is true, I also check if notify counter is greater than zero. If both true, I send the message. If "changed" flag is false, I check again if the notify counter is greater than zero, I send the message. This way it works, but it is kind of a patch than a good design fix. I am yet to find a good solution.
Thanks,

Problem with Threads and "plase wait..."-Window
Hi everyone,
I have a problem that I'm not able to solve in any way... I have a time-consuming task (a file decryption) which I execute in a separate thread; I've used the SwingWorker class, like suggested by sun-tutorial, and it works right. The problem is that I have to wait that the decryption have finished before continuing with program-execution. Therefore I would like to display a "please wait"-window while the task runs. I've tryed all the possible ways I know but the problem is always the same: the waitWindow is displayed empty, the bounds are painted but the contents no; it's only painted when the decrypt-task has finished. Please help me, I have no more resources....
decrypt-file code:
public class DecryptFile {
private String cryptedFileNameAndPath;
private ByteArrayInputStream resultStream = null;
// need for progress
private int lengthOfTask;
private int current = -1;
private String statMessage;
public DecryptFile(String encZipFileNameAndPath) {
cryptedFileNameAndPath = encZipFileNameAndPath;
//Compute length of task...
// 0 for indeterminate
lengthOfTask = 0;
public ByteArrayInputStream getDecryptedInputStream() {
return this.resultStream;
* Called from ProgressBarDemo to start the task.
public void go() {
current = -1;
final SwingWorker worker = new SwingWorker() {
public Object construct() {
return new ActualTask();
worker.start();
* Called from ProgressBarDemo to find out how much work needs
* to be done.
public int getLengthOfTask() {
return lengthOfTask;
* Called from ProgressBarDemo to find out how much has been done.
public int getCurrent() {
return current;
public void stop() {
current = lengthOfTask;
* Called from ProgressBarDemo to find out if the task has completed.
public boolean done() {
if (current >= lengthOfTask)
return true;
else
return false;
public String getMessage() {
return statMessage;
* The actual long running task. This runs in a SwingWorker thread.
class ActualTask {
ActualTask () {
current = -1;
statMessage = "";
resultStream = AIUtil.getInputStreamFromEncZip(cryptedFileNameAndPath); //here the decryption happens
current = 0;
statMessage = "";
}The code that calls decryption and displays waitWindow
final WaitSplash wS = new WaitSplash("Please wait...");
final DecryptFile cryptedTemplate = new DecryptFile (this.templateFile);
cryptedTemplate.go();
while (! cryptedTemplate.done()) {
try {
wait();
} catch (Exception e) { }
this.templateInputStream = cryptedTemplate.getDecryptedInputStream();
wS.close();Thanks, thanks, thanks in advance!
EdoardoMaybe you can try setting the priority of the long-running thread to be lower? so that the UI will be more responsive...

Problem with threads and graphics
I have a thread that chooses paths for a Travelling salesman problem, it then calls a TSPdraw class and passes it the path, which the class then draws. the problem is when i have two threads it creates two windows but only draws a path in one of them. any ideas where i`m going wrong
Are you using swing components? Swing isn't threadsafe. If you have multiple threads that want to update your UI you need to use the SwingUtilities.invokeLater(...)or invokeAndWait(...). There is a page in the swing tutorial about this at: http://java.sun.com/docs/books/tutorial/uiswing/misc/threads.html

Problem with threads and ProgressMonitor
Dear Friends:
I have a little problem with a thread and a ProgressMonitor. I have a long time process that runs in a thread (the thread is in an separate class). The thread has a ProgressMonitor that works fine and shows the tasks progress.
But I need deactivate the main class(the main class is the user interface) until the thread ends.
I use something like this:
LongTask myTask=new LongTask();
myTask.start();
myTask.join();
Now, the main class waits for the task to end, but the progress monitor don`t works fine: it shows only the dialog but not the progress bar.
What's wrong?Is the dialog a modal dialog? This can block other UI updates.
In general, you should make sure that it isn't modal, and that your workThread has a fairly low priority so that the UI can do its updating -
Problem with threads and/or memory
I'm developing an application where there are 3 threads. One of them sends a request to the other, and if the 2nd can't answer it, it sends it to the 3rd (similar to CPU -> CACHE -> MEMORY). When i run the program with 1000-10.000 requests, no problem occurs. When i run it with 300.000-1.000.000 requests, it sometimes hangs. Is this a problem with the garbage collector, or should it be related to the threads mecanism.
(note: eache thread is in execution using a finite state machine)i had been running the program inside Netbeans.

Edited by: AMARSHI on Jul 10, 2008 7:07 AMThe reference variable itself, takes up the same amount of space, of course, as all references are the same size. Now, the object on the heap is a different story. With null there isn't one, of course (or if there is there is only one for the entire VM), and for the second a String object will be created in the String pool (once again, only one for the entire VM that every = "" assignment will use). But really, what difference does it make? If there is a difference, it is on the order of a few bytes (at max) for the entire VM, and if this is a concern, your probably doing something else greviously wrong. This miniscule difference should not concern you.
Edit: And "nulling" variables to "save" memory is also not something you should be concerned with. Either the variable will go out of scope and the object garbage collected anyway, or it's in constant use and so will not be taking up any extraneous heap space. If one of those is not the case, you are, once again, doing something greviously wrong. -
And/or if statement in rtf templates.
Hi all,

fx. <?if:doc_type='STANDARD'?> OR <?if:doc_type='DEFAULT'?>
How can I do this?
In advance thank you.
Best regards
KennethHi D,
Thank you for your answer.
I have seriously thought about that solution; but I don't think it's a smart way to do it.
If i do it like that, i need to copy the whole table and paste it inside the if statements.
I have two xml elements that I need to make the decisions on. POH_PO_TYPE & CP_RELEASE_NUM.
POH_PO_TYPE can be: STANDARD, RELEASE or BLANKET.
CP_RELEASE_NUM can be: '' or N
If POH_PO_TYPE is RELEASE AND CP_RELEASE_NUM is not ''
OR POH_PO_TYPE is STANDARD
OR POH_PO_TYPE is BLANKET AND CP_RELEASE_NUM is ''
THEN show table (which contains the whole PO).
It shall show the content of the PO in any of these cases.
