Calling a form from another form?

Hello,
User searches for data by clicking search button. This brings up my canvas C_view related to block B_view.
I put a 'when-mouse-double-click' trigger on my view block B_view.
In that trigger I have a call to a program unit P_CALL_FORM.
My idea is to call a form and pass the values from the record on which the user double clicks.
For now I have the following code in my P_CALL_FORM:
PROCEDURE P_CALL_FORM IS
   L_pl_id   ParamList;
   x         number;
BEGIN
   Open_Form ('lcimpedt',
              ACTIVATE,
              SESSION);
EXCEPTION
   when FORM_TRIGGER_FAILURE then
      raise;
   when OTHERS then
      emessage(SQLERRM);
      raise FORM_TRIGGER_FAILURE;
END;When I double click on any record in the C_view, the called form 'lcimpedt' does not come up. Any suggestions
why the form is not showing up?(that form 'lcimpedt' is in the same directory of the application as my calling form. both of them are 10g forms.)
Thanks,

Andreas,
Thank you for your valuable suggestions.
"If you have a hundred users with each opening two connections you have 200 connections instead of 100. Also, having two connections means that you have two transactions, so one user could lock himself in one forms-application by trying to change the same record in two db-sessions. And, commiting only affects the "active" session. So if the user changes in two sessions he will have to commit two times (Of course, this could also be a positive argument)."
I totally agree with the above.
There are very few users(infact may not be more than 3) to the form that I am working on...so opening multiple connections should not be a problem.
Currently there are some forms in the application with the similar functionality(although in that case....when they try to edit, they are editing completely different information than what is in the calling form). I am trying to mimic the same thing (not that it is the right way of doing things) ...just so that the users get what they are used to. So, switching between windows is something that they are used to...and I think its a non-issue.
The only other thing that I think will be a problem is users potentially locking themselves up. Do you know if using pl/sql tables/collections for this would be a good idea to solve this? Can pl/sql tables/collections be used with forms?
Thanks,
Chiru

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 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);

Calling a method from another file

This is pretty basic stuff but i can't seem to get it right. I am calling a method from another file. The other file IS located in the same folder BUT when i compile i get errors
"cannot find symbol" <===referring to limit and sieve i believe.
The method name is "sieve" the file name is "PrimeSieve2008" and "limit" is the variable in brackets in the real method.
     public static void main (String [] args) {
final int [] PRIMES;
int sieve = PrimeSieve2008.sieve(limit);
     PRIMES = sieve(getValidInt());
          for (int j = 0; j<PRIMES.length; j++) {
               System.out.println("Prime[" + j + "] = " + PRIMES[j]);
Is "int sieve = PrimeSieve2008.sieve(limit)" the wrong way to call a file?
Thanks a million,
Alex

I really am clueless here.in this one you are passing in limit.
in the other one you are getting limit from somewhere outside of main.

Calling a method from another class... that requires variables?

I'm calling a method from another class to change the date (its a date object) in another class.
I keep getting the error 'setDate(int,int,int) in Date cannot be applied to ()'
My code is:
public int changeDate()
cycleDate.setDate();
}I'm guessing I need to pass 3 parameters (day, month, year), but I'm not sure how! I have tried, but then I get errors such as ')' expected?
Any ideas! :D

Any ideas! :Dyou need to post your code if you're getting specific errors like that.
but typically ')' expected means just that, you have too many or not enough parenthesis (or in the wrong place, etc.)
i.e. syntax error

Calling a servlet from another servlet?

Hi
I would like to know that how can I call one Servlet from another Servlet. I have tried getServlet() method of ServletContext but it has been deprecated. I want to call a specific method of the other Servlet, is there any other way?
Thanks

I should have seen it from your previous post :(
Code of Servlet 1:
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws
ServletException, IOException
RequestDispatcher rDispatch = null ;
rDispatch = getServletConfig
().getServletContext().getRequestDispatcher
("/Servlet2") ;
rDispatch.forward(request, response) ;
System.out.println("Back in 1");
I assume Servlets 1and 2 are in same web app and you've mapped your servlet2 to /Servlet2 in your web.xml
make it as
rDispatch = request.getRequestDispatcher("/Servlet2");
rDispatch.forward(request,response);
Nothin's wrong with yer servlet2

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", ............)

Dear Naing,
I execute the same code

GET PARAMETER ID 'VRT' FIELD LS_EKPO.
SET PARAMETER ID 'VRT' FIELD ls_ekpo.
CALL TRANSACTION 'ME33K' AND SKIP FIRST SCREEN.

And it is working.
Try to do de simple sintax.
