Show_url and open_browser

Hi All,
I wanted to know if show_url of class cl_gui_html_viewer serves teh same functionality as open_browser ?
We have all our applications calling open_browser and I am to implement an OSS note that mentions about show_url. Can anyone throw some light on this please ?

Hello,
SHOW_URL will only navigates to the URL specified in the HTML Control.
In case if you want an browser instance to be created you can call the method SHOW_URL_IN_BROWSER, this will create a new instance of browser and navigates to the URL passed. If you close the sapgui session, the browser is also closed. In case if you dont want the browser to be closed when sapgui session is closed use the method DETACH_URL_IN_BROWSER.
Best Regards

DETACH_URL_IN_BROWSER versus SHOW_URL

Goodafternoon,
Can anybody explain me what the differents in the class CL_GUI_HTML_VIEWER is between
the method "DETACH_URL_IN_BROWSER" and method "SHOW_URL with parameter IN_PLACE = ' '".
When i open a url with Show_URL and parameter in_place = ' ' the result is not shown in the browser.
If i open the url with the method detach_url_in-Browser this is working.
tnks.

Hi,
As far as I understand:
The difference is that in the methos
DETACH_URL_IN_BROWSER -
> Internally an SAP 'CALL BROWSER' FM is called that open the usrl in that browser.
SHOW_URL with parameter IN_PLACE = 'X' ---(This is default) should work.
SHOW_URL with parameter IN_PLACE = ' ' means that the methods assumes the URL passed is an absolute URL.
I hope this answers your question.

Saurabh

Few questions about apex + epg and cookie blocked by IE6

Hi,
I would like to ask a few questions about apex and epg.
I have already installed and configured apex 3.2 on oracle 10g (on my localhost - computer name 'chen_rong', ip address -192.168.88.175 ), and enable anonymous access xdb http server.
now,
1. I can access 'http://chen_rong' , 'http://localhost' , 'http://192.168.88.175' without input username / password for realm 'XDB' in IE6;
2. I can access 'http://localhost/apex/apex_admin' , 'http://192.168.88.175/apex/apex_admin' , and I can be redirected into apex administation page after input admin/<my apex admin password> for realm 'APEX' in IE6;
3. I can access 'http://chen_rong/apex/apex_admin' in IE6, but after input admin/password , I can not be redirected into administation page, because the cookie was blocked by IE6.
then, the first question is :
Q1: What is the difference among 'http://chen_rong' , 'http://localhost' , 'http://192.168.88.175' ? I have already include site 'chen_rong' into my trusted stes! why the cookie was blocked by IE6. I have already tried firefox and google browser, both of them were ok for 'chen_rong', no cookie blocked from site 'chen_rong'!
and,
1. I have tried to use the script in attachment to test http authentication and also want to catch the cookie by utl_http .
2. please review the script for me.
3. I did:
SQL> exec show_url('http://localhost/apex/apex_admin/','ADMIN','Passw0rd');
HTTP response status code: 401
HTTP response reason phrase: Unauthorized
Please supplied the required Basic authentication username/password for realm XDB for the Web page.

my second questions is :
Q2: After I entered into realm 'XDB', I still need went into realm'APEX'. how could I change the script show_url to accomplish these two tasks and successfully get the cookie from site.
the show_url script is as following:

I use oracle database enterprise edtion 10.2.0.3. I have already figured out the epg on 10.2.0.3 to support apex 3.2.
And as I described above, the apex site works fine for ip address , and localhost. but the cookie will be blocked by IE6, if I want to access the site by 'http://computername:port/apex/apex_admin'. This problem does not occured in firefox and google browser. Could someone give me answer?

How to Generate and Display SVG Graphics in ABAP

Hi everybody,
I tried to complete the Tutorial "How to Generate and Display SVG Graphics in ABAP, Part 1" by Siarhei Ulasenka (https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/ad83a990-0201-0010-d680-a189f8bc20fa).
Unfortunately when I tried the example to display an SVG Drawing in an ABAP Report I get the error message "Es ist ein Laufzeitfehler aufgetreten, ungültiges Zeichen" (english should be something like "Runtime Error, unkown character"). But it works when I open the svgfile in a new IE Window (parameter in_place from cl_gui_html_viewer->show_url). Also when I open a svg file from the local disc it works fine.
The code:
    CALL METHOD html_control->load_data
      EXPORTING
        url            = 'chart.svg'
        type         = 'image'
        subtype    = 'svg+xml'
      CHANGING
        data_table = lt_svg
      EXCEPTIONS
        OTHERS     = 1.
    CALL METHOD html_control->show_url
      EXPORTING
        url        = 'chart.svg'
        in_place   = 'X'
      EXCEPTIONS
        cntl_error = 1.
Has anyone a solution? Thanks in advance for your help!

Kathrin

Hello Alex,
The Corel SVG viewer has problems loading and displaying the examples (see the list of limitations at their site). Try to use the Adobe viewer instead.

Does SAP ECL viewer has drag and drop functionality...

Hi,
Does ECL viewer has drag and drop functionality for example we can drag and drop file from windows sever to SAP. So that it can be used later on using BDN.
Thanks.

Implement this program, it is a cut/paste solution. Again, you must have the ECL component installed on your SAPgui.

Now drap a PDF file from the left container, and drop in the right side. Slick, right?

Calling BSP from report and return control back ?

Hi All,
      My requirement is as follows :-
1. I am calling a BSP from report using CL_GUI_HTML_VIEWER->show_url. The BSP page is displayed successfully.
2. Then, I perform some operations and want to return some data back to the main program (from where it was called - Report) and continue execution from there
How do I accomplish the second requirement (Control doesnt come back once I close the BSP) ?
Regards,
Ashish

how to generate events from html code in the html control back to your ABAP check out this demo program
SAPHTML_EVENTS_DEMO
say for example, in your case you are showing the BSP in GUI HTML control and on clicking a link you want to pass some data from your link to ABAP program and the ABAP should receive the value and process it and may be comeback to same BSP or go some to some other screen/transaction.
steps to follow:
after creating the html control
register event for call back and call the BSP url.
create object hviewer
             exporting
               parent = mycont.
    myevent-eventid = hviewer->m_id_sapevent.
    myevent-appl_event = 'x'.
    append myevent to myevent_tab.
    call method hviewer->set_registered_events
      exporting
        events = myevent_tab.
    create object evt_receiver.
    set handler evt_receiver->on_sapevent
                for hviewer.
    hviewer->enable_sapsso(
      exporting
        enabled    = 'X'
      exceptions
        cntl_error = 1
        others     = 2
    if sy-subrc <> 0.
    endif.
    call method hviewer->show_url
      exporting
        url = wf_url.
in your BSP the link should look like below
A HREF=SAPEVENT:TAGS?value to be passed to your ABAP> link text </a
when you click this link in bsp then you can then capture the value "TAGS" to know which link was clicked and the value passed after the ?
link is just one option, you can also send whole form data.
this type of link and form will only work when your BSP is invoked within HTML contro. if its invoked from standalone browser these wont work. so you amy want to dynamically show/hide "sapevent" links based on where it runs.
Hope this is clear. if not do getback.

WDA and SAP-GUI-Integration

Hello,
I am testing the integration of an WDA in the SAP-GUI via cl_gui_wdr_viewer and events. it works fine but now i have new challange where i have some problems.
I the new case, the WDA should run on another Server. I call the WDA with the cl_gui_wdr_viewer->show_url( ), thats works fine but in this case there is no cl_wdr_sapgui_integration-instance in the WD available ?!?
Does anybody know the condition for the availability of this instance ?!?
Thx
Thomas

Some seperate Installation requirements are need to Install SAP GUI.........

HTML VIEWER cl_gui_html_viewer and MIME objects - can't display

Hi,
I try to display a dynamic HTML page with some pictures staright fro a ABAP list:
I have the following code snipet:
CALL METHOD html_control - >load_mime_object
     EXPORTING
          object_id = 'ZWN'
          object_url = 'ZWN.GIF'
     EXCEPTIONS
          OTHERS     = 1.
CALL METHOD html_control - >load_data
EXPORTING
     type                 = 'text'
    subtype              = 'html'
IMPORTING
    assigned_url         = v_doc_url
CHANGING
    data_table           = lt_my_html
EXCEPTIONS
    dp_invalid_parameter = 1
    dp_error_general     = 2.
IF sy-subrc EQ 0.
CALL METHOD html_control - >show_url
    EXPORTING
     url      = v_doc_url
      in_place = ' '.
endif.
All objects are checked in via SMW0.
In the HTML Code, I have the pictures this regular way:
....<im g sr c=zwn.gif......
If I have it run like this, the pictures are not displayed.
If I do it the way to leave out the HTML page and display it directly:
CALL Method ....load_mime_object.....
CALL Method....show_url, the picture is displayed.
What am I doing wrong?

Hello Holger,
as the status of this thread is "Answered", I would be very thankful to get your solution.
Does it only work with the in-place-option or did you find something else.
THANK YOU !!!

http://www.sapmaterial.com/tablecontrol_sap.html
Custom Controls
A custom control is an area on a screen. You create them in the Screen Painter, and, like all other screen objects, they have a unique name. You use custom controls to embed controls. A control is a software component on the presentation server, which can be either an ActiveX control or a JavaBean, depending on the SAPgui you are using. They allow you to perform tasks, such as editing texts, locally on the presentation server. The control is driven by the application logic, which still runs on the application server.
The SAP Control Framework
The controls on the presentation server and the ABAP application programs on the application server communicate using the Structure link SAP Control Framework. This is programmed in ABAP Objects, and contains a set of global classes that you can find in the Class Browser under Basis ® Frontend services. These classes encapsulate the communication between the application server and presentation server, which is implemented using Remote Function Call.
All application controls are encapsulated in a global class. You can find the SAP Basis controls in the Class Browser under Basis ® Frontend Services or Basis ® Component Integration. Programs that use controls on a screen work with the methods and events of the global classes that encapsulates them.
Container Controls
Before you can work with a custom control on a screen, you must assign a Structure link SAP Container Control to it. Container controls are instances of special global classes from the SAP Control Framework. The global class for custom controls is called CL_GUI_CUSTOM_CONTAINER. To link a custom control to a container control, pass the custom control name to the CONTAINER_NAME parameter of the container control constructor when you instantiate it.
As well as using custom containers, you can link controls to a screen using a SAP Docking Container. This is encapsulated in the global class CL_GUI_DOCKING_CONTAINER. The SAP Docking Container does not place the control within a screen. Instead, it attaches it to one of the four edges. You can nest containers. For example, you can use the SAP Splitter Container (classes CL_GUI_EASY_SPLITTER_CONTAINER or CL_GUI_SPLITTER_CONTAINER) within other containers. This allows you to split a custom control or docking control into more than one area, allowing you to embed more than one control.

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

}

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,
B.D.

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() {

}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!
