      range_line LIKE LINE OF range_tab.
rspar_line-selname = 'SELCRIT1'.
rspar_line-kind    = 'S'.
rspar_line-sign    = 'I'.
rspar_line-option = 'EQ'.
rspar_line-low     = 'ABAP'.
APPEND rspar_line TO rspar_tab.
range_line-sign   = 'E'.
range_line-option = 'EQ'.
range_line-low    = 'H'.
APPEND range_line TO range_tab.
range_line-sign   = 'E'.
range_line-option = 'EQ'.
range_line-low    = 'K'.
APPEND range_line TO range_tab.
SUBMIT report1 USING SELECTION-SCREEN '1100'
               WITH SELECTION-TABLE rspar_tab
               WITH selcrit2 BETWEEN 'H' AND 'K'
               WITH selcrit2 IN range_tab
               AND RETURN.

How to call one .SWF from another?

How do I call one .SWF from another. I built a very beefy
base .SWF, and want to add music overlay, and an intro slide show
to the exsting Flash animation, but put it in a second .FLA/.SWF
file. How do I call one from the other?
This will be embedded in an HTML file but I assume this is
superfluous to my question.
F.Z.

I think you should open that Another SWF (FLA),
and add some actionscript..
For example, you could create a movie clip, and write
actionscript in the
first keyframe:
loadMovie("
http://www.somewebpage.com/movie.swf",
this);

Hi ken Thanks for replying....
Ya i packed it as a jar (using Export tool in Eclipse3.2)....
I am using SUN AS 9.....
I packed bean1 and bean2 as two different jars in the same domain...
Here is my code...
Bean1:
@Stateless(mappedName="ejb/Second")
public class SecondIMPL implements SecondRemote {
     public FirstRemote obj;
     public String connect() {
          try{

               FirstRemote obj =(FirstRemote)ctx.lookup("ejb/First");
               System.out.println("Client :"+obj.bMethod());
          }catch(Exception e){
               e.printStackTrace();
          return "Check server Log";
}Bean2 :
@Stateless(mappedName="ejb/First")
public class FirstIMPL implements FirstRemote {
     public String bMethod() {
          return "From First Bean";
Client:
public static void main(String[] args) {
          try{
               InitialContext ctx= new InitialContext();
               SecondRemote obj =(SecondRemote)ctx.lookup("ejb/Second");

like
call first procedure ,basing on the return value
i.e if p_poid != 0 then
we need to call second procedure
in the loop.

CALL TRANSACTION 'ME33K from another program

Hi,
I ma trying to CALL TRANSACTION 'ME33K from another program, but it is not working. The transactions is opening, but it is not opening with the contract number (ls_ekpo-ebeln) i am passing.
ls_ekpo-ebeln does have a valued when CALL TRANSACTION 'ME33K is called.
In debug, I noticed the "value" is blank when step into CALL TRANSACTION 'ME33K .
   WHEN 'EBELN'. "Contract
      l_field = 'EVRTN'.
     IF ls_ekpo-ebeln <> ''.
        GET PARAMETER ID 'VRT' FIELD l_field. "EVRTN.
       SET PARAMETER ID 'VRT' FIELD ls_ekpo-ebeln.
       CALL TRANSACTION 'ME33K AND SKIP FIRST SCREEN.
        SET PARAMETER ID 'VRT' FIELD ls_ekpo-ebeln.
      ENDIF.
Any help or suggestions would be great.
Thanks,
Naing

Dear Naing,
I execute the same code
IF ls_ekpo IS INITIAL.
GET PARAMETER ID 'VRT' FIELD LS_EKPO.
SET PARAMETER ID 'VRT' FIELD ls_ekpo.
CALL TRANSACTION 'ME33K' AND SKIP FIRST SCREEN.
SET PARAMETER ID 'VRT' FIELD ls_ekpo.
ENDIF.
And it is working.
Try to do de simple sintax.
A program with one pararmeter to introduce the contract number.
The set parameter for this parameter and the call transaction.
I´m waiting your comments.
Regards.
Antonio.

How to call a servlet from another servlet

hi everybody,
i have a problem, i have to call one servlet from another one.
Everything works on my pc, but when i install the application on the customer's server i got an error about an Uknown URL followed by the name of the machine.
Wjat i do is the folloqing :
String urlString = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+"/"+servletName;
URL url = new URL(urlString);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
the variable servletName is the name of the servlet i have to call.
Is there another way to call the servlet ?
All the servlet are installed in the same server.
Any suggestion ?
Cheers.
Stefano

Sweep is correct about requestDispatcher being another approach for inter-servlet delegation; the only issue that i recall with this approach is that it defaults the method of the destination servlet to the one it was called from...for example, calling servlet2 from within servlet1.post() resulted in the dispatcher attempting to utilize servlet2.post() - i believe that i searched for a parameterize solution to no avail :( (ended up handling the request by placing a "fake" doPost() in servlet2 that simply called servlet2.doGet())
however, if your application is functioning correctly on your pc/webserver then the problem may be external to servlet communication (e.g. client webserver's ports not configured or blocked, missing runtime classes, etc.)
my suggestion would be to set aside the programmatic concerns for the moment - what is the response if you open a browser on a client's machine and access the URL in question (i.e. http://clientserver:port/stefanoServlet)? If it will not respond to access in this manner then it certainly won't when your application calls for it.
It's possible that there is a coding error but, given the info supplied, i'd start examining the environment, first. Let us know if you have any luck with the test i recommended or not (please provide abundant detail). Or, if you've found the solution then you may want to post back with a quick blub so the next person knows how to escape the trap.

How to call a BSP from another BSP?

Hi All,
I've created a BSP for hiring new employees. I have a situation whereby when the user presses a button a pop window will be displayed listing all the positions in the company. The user selects the correct position, which then populates an input box on the originating page and the pop up window closes.
This pop up window is a page in another bsp which goes off and gets the positions and stores the selection in a cookie.
Now my problem is how do i call this 'get postions' bsp from my originating bsp?
I've tried using the <%@ include file="/sap/bc/bsp/sap/z_hr_org_model"%> but i get the error only page fragments can be included.
So how do i call one bsp from another??
Any help would be much appreciated,
Kind Regards,
Liz.

Look at the below [link|http://****************/Tutorials/BSP/F4Help/Tutorial.htm]
The only difference in your case is, you need to call the popup from different BSP Application.
To do that, just add the full path when you call the document.open..
For example,
document.open("/sap/bc/bsp/sap/z_hr_org_model/main.do", ............)

CallerPrincipal when calling one sessionbean from another

Hi all,
I have a little problem when calling one sessionbean from another sessionbean. The problem is, that in the method, which is called, is used SessionContext's getCallerPrincipal().getName(). This works great from client, but from other sessionbeans getCallerPrincipal() retuns an "ANONYMOUS" principal. How can I set the correct principal (the principal from the first sessionbean)?
Thank you
My env: Glassfish 2.1.1, Netbeans 6.8, Eclipselink 2.0.0, Java 1.6.0.18
My code:
@Stateless
public class ABean implements ASessionRemote{
@Resource
SessionContext ctx;
@Override
public void aMethod(){
String name = ctx.getCallerPrincipal().getName(); // the name is ANONYMOUS, when the call is done from other sessionbean
@Stateless
public class BBean implements BSessionRemote{
@Resource
SessionContext ctx;
@EJB
private ASessionRemote aSessionBean;
@Override
public void bMethod(){
aSessionBean.aMethod();
}

"This works great from client"
What do you mean by this, i.e what sort of client are you using (stand alone app, servlet) ?
what shows up if you printout the caller principal in the calling bean ?
are the two ejbs in the same ear ?
what security meta-information are you using in ejb-jar.xml and sun-ejb-jar.xml, if any ?

How to refer one view from another view?

Hi,
I have 2 views in my Adobe Flash Builder mobile app. I need to refer the first view in my second view.
How to refer one view from another view? Or how to create a reference to a view wherever needed?

I don't need any data from my first view. In a certain flow, I need to make my first view to be invisible.
for eg., My First view is in portrait mode. I change the device to Landscape. In the landscape mode, I want to show a completely different view (second view).
In this case, what happens is, I see my first view in Landscape mode for a second. Then the second view appears. When I change to Landscape mode, only the second view should be seen. I need to make my first view to be completely invisible in the OnOrientationChanging event of
StageOrientationEvent
As stage object and StageOrientationEvent works at application level, I need to know how to refer my first view object in the application level.
private function onOrientationChanging(soe:StageOrientationEvent):void
MyFirstView.Visible = False; ====> don't know how to refer MyFirstView here
Is my question clear now?

How to call one JSFF into another JSFF

Hi,
I am very new to ADf. Could you please tell me how to call one JSFF inside another JSFF. We have a common pop-up written in one JSFF. Is there any best approach to get this pop-up into other JSFF.
Thanks in Advance.

How to call a process from another project

Hi;
How to calling a process from another process in another project? Which activity that i need or web service, direct binding? I use 11g

Hi Tulasi ;
I have wsdl of the process i need to call. Also wsdl address on the server. But CALL activity can't use to service call. CALL activity can use only to reusable process call.
I think, this operation must make on composite.xml. But I have a same problem with this method and it don't work.
I create a base process that looking at below. It's include a direct binding. Is it include a direct binding?
[Base Process|http://d1201.hizliresim.com/t/s/21wqu.png]
Then i create a process that call to base process:
[Caller Process|http://d1201.hizliresim.com/t/s/21wqx.png]
I paste to base process' wsdl address on the server. Then i select port type (BaseProcessPortType) and a warning has occured that you see the picture above. Base Process contain Oracle SOA Composite Type. What's the wrong? It happened for Callback Port Type.
And second question is what's the Address? (under Reference Binding Setails option).
I think, i create the this direct binding correctly, i call to base process into my caller process via service activities.

Calling one script from another

InDesign has a nice mechanism for calling one script from another, so code can be made modular. What about FrameMaker ExtendScript? What methods are people using to call one script from another? Thanks for any suggestions.
Rick Quatro

Hi Trevor,
Note that ExtendScript is Javascript plus FM objects and methods, so you need to stick to Javascript syntax rules. The right way to include another script source is as follows:
#include "scriptname.jsx";
If this works when running the main script from the ESTK, you know it finds the included script. When you then Export the script to Binary (from the File menu of the ESTK), the binary will include the embedded script as well. After this you have a jsxbin file, which you can drop into one of the two available startup folders to make it fire automatically when FM starts. Or you can move it anywhere else and run it via the File > Script > Run command. The main idea here is that when compiling a script into binary format, all include references are resolved and the script contains the complete code. If you run the jsx, the script is interpreted and requires a correct relative reference to any included script.
I hope this clarifies things a little
Ciao
