please help me

Do you have the partialTriggers set correctly on the 3rd and 4th level tables?
As an alternative, you could write a custom selection listener for table 2 and programmatically ppr the 3rd and 4th tables..

Function calling problem

Hi,
I created a class file and in constructor loading a XML file
and on Load of XML I am calling different function with in the same
class, but it is not executing can you please tell me where is the
problem.
Here is the code given below.
class myClass
private var myXML:XML;
public function myClass()
myXML.load("myXML")
myXML.onLoad = function()
displaText() // This is the function which is not calling
public function displaText()
trace("Welcome")
}

It looks like you've got a scoping issue...
try:
var pointer:myClass=this;
myXML.onLoad=function(success){
if(success){
pointer.displaText();
}else{
// error handling
When you call a function within an onLoad event, that
function is scoped to the object being loaded. If you want to call
a method from another object (in this case from your 'myClass'
class), you need to use a reference to the object that contains the
function.
Don't forget to use the new XML constructor when
instantiating your XML object:
myXML= new XML();
Also... it's a best practices thing... you should capitalize
your class names (MyClass instead of myClass). You'd then likely
use the lower case (myClass) to name an instance of the class.

Stored function call problem

I've been trying out this feature as it was shown in adfdeveloperguide. that is, on page 3-26/27
StoredFunctionCall functionCall = new StoredFunctionCall();
functionCall.setProcedureName("READ_EMPLOYEE");
functionCall.addNamedArgument("EMP_ID");
functionCall.setResult("FUNCTION_RESULT", String);
ReadObjectQuery query = new ReadObjectQuery();
query.setCall(functionCall);
query.addArgument("EMP_ID");
Vector args = new Vector();
args.addElement(new Integer(44));
Employee employee = (Employee) session.executeQuery(query, args);
in my version it is:
StoredFunctionCall fCall = new StoredFunctionCall();
fCall.setProcedureName("f_milos");
fCall.addNamedArgument("x");
fCall.setResult("FUNCTION_RESULT", String.class);
ReadObjectQuery query = new ReadObjectQuery();
query.setCall(fCall);
query.addArgument("x");
Vector args = new Vector();
args.addElement(new Integer(2));
String result = (String) session.executeQuery(query,args);
where f_milos is my stored function. as for the session, I got it in this way
Session session=new SessionFactory("META-INF/sessions.xml", "default").acquireSession();
like it was done in my session bean.
dunno, maybe thats the source of the problem.
now, when I come to executeQuery, following error pops:
javax.faces.el.EvaluationException: Exception [TOPLINK-6029] (Oracle TopLink - 10g Release 3 (10.1.3.0.0) (Build 060118)): oracle.toplink.exceptions.QueryException
Exception Description: A reference class must be provided.
Query: ReadObjectQuery().
help?

Well, previously you were calling getDBTransaction() on an explicit Application Module object, whereas now, you do:
st = getDBTransaction().createCallableStatement("begin ? := "stmt";end;",0);which means that your code must be inside of an application module in order to work. Do you see the difference?
I'll mention that you shouldn't generally be doing DB calls in your ViewController/UserInterface layer - DB code belongs in the model.

Installation problem - urgent, PLEASE help!!

I'm trying to install Java3D and somehow it doesn't seem to be working. I'm not sure whether I should be installing the opengl or the
directx version, but I've tried both with no luck. I'm running Windows
M.E.
I downloaded the JSDK beta 1.4 version (I have previously tried also
with the 1.3 version, this didn't work either), and now have the
jdk1.3.1 as a folder on my C drive ( C:\jdk1.3.1) . Then I downloaded
Java3D from the website, onto C, as an executable file. When I clicked
it, it went through the installation process (not giving me any
options for where to install it, i was just clicking on 'next') and
seemed to complete ok, but I'm trying to test it by running the
helloUniverse demo, and the file isn't even there. There's a Java3D
folder which has been created in Windows, but this just contains a
folder called uninstall_info.
On my Java plug-in control Panel, it is currently set to 'use java
plug-in default'. The other options are to use JRE or JDK, in folders
Program Files\JavaSoft or JDK1.3.1 respectively. I don't know which
one I should be choosing! I think I tried it with the JDK option
before and that didn't work either.
If anyone can please help I'd be really grateful, this is getting
quite urgent!

Hi there!
Well, try installing java3d in the same directory as ur java(which is c:\jdk1.3.1 for u).
If i am not mistaken, java3d, by default, installs in c:\jdk1.2.2 directory.
U also have 2 set the path and classpath in the autoexec.bat to addr to \bin and \lib sub-directories resp.

Tomcat problem urgent please

Hi! All
I just installed jdk1.1.8 and jakarta-tomcat 3.3.2 on windows 2000.
I also set the path, java_home and tomcat_home as required. But when I try to run Tomcat, it says "Starting Tomcat in a new Window", then a new window opens up and closes immediately.
Please advice.
Thank in advance.

Edit the ... I think it's tomcat.bat file, and where it says something like:
call "%TOMCAT_HOME%\bin\tomcat-startup" start %1 %2 %3 %4 %5 %6 %7 %8 %9
Change start to run. This will make it start tomcat in the same window and let you see what the error message is. Most likely it's either a classpath problem, or another application using the port tomcat is trying to use.

Ipod touch restore problem *URGENT PLEASE HELP*

Ok well I just inherited an Ipod touch from my friend who upgraded to a iPhone and it has a lock code, which I don't know. I called up my friend and asked him the code, he didn't know it of course... so i just guessed passwords and it said it was locked, I only have one more try until it locks permanently. So, I tried resetting it and it didn,t work. so i put it in recovery mode and it was gonna be ok, but my problem is I have slow dial-up internet and cannot re-download the software because my internet turns off randomly and it takes about 35 hours straight to download the 280MB, my other problem is that every time the download is disrupted, what itunes has already downloaded deletes itself and I have to start over from zero. I cannot fully download the software and have no access to hi-speed internet, I need a solution please otherwise im sitting here with a $300 piece of junk.

Just bring it over to your friends house and have him reset it for you. Then bring it to your house to put your music on it.
It is as simple as that. Too bad you have dial-up still. I use broadband and it is very fast.

Drawing 2d line chart problem, urgent please!!!

Hello,
can anyone help me with the function GRAPH_MATRIX_2D please,
i couldn't draw a line graph with three data series, i mean with three lines in the graph.
i want to the chart to be drawn as line graph at the beginning, i shouldn't have to change the chart type later,
can anybody send me a sample code that does what i want.
i am expecting your answers,
thanks.

Hi,
have you checked the two reports Matthias mentioned?
After downloading the SAP Chart Designer the general procedure should look like: create your chart settings interactively using the designer. Save these settings as a local XML file. Use this XML in your ABAP application and additionally create a data XML at runtime (the format is described in the pdf of the SAP Chart Designer zip).
Regards, Kai
PS: Please don't use these very outdated function modules graph_matrix* / grstat* in new projects!

Venkat,
You can do that in two ways. Once is to set it in the USER DEFAULTS. Go to SU01 and you can see a tab for DEFAULTS.. There will be a check box for PRINT IMMEDIATELY.
Or you can do that in the SMART Form parameters also. In the OUTPUT_OPTIONS parameters ther is a field TDIMMED. Set that to 'X'. That should print the form immediately.

Session and Refresh problem, Urgent, please help

          Hi, Dear Everyone:
          I have two questions to ask. (Environment: OS: Nt4.0, Server: Weblogic5.1)
          (1). When I use session to store an object in servlet (processed results
          from database) then dispatch to a jsp page to display the results, I got the following

          session.setAttribute("PostTitlePool", temp);
          String url = "/ccproject/subdisplay.jsp";
          RequestDispatcher dis = getServletContext().getRequestDispatcher(url);

               out.print(sq.getTitle());
          %>
          Please tell me what I did wrong or What more do I need to do?
          (2). If I changed to use request.setAttribute in servlet, it works. But I got another
          strange
          result from browser. That is, if I keep on clicking refresh (IE5.5), the same result
          appending
          the previous one on the same page.
          Here is my code in servlet:
          req.setAttribute("PostTitlePool",temp);
          String url = "/ccproject/subdisplay.jsp";
          RequestDispatcher dis = getServletContext().getRequestDispatcher(url);
          dis.forward(req, res);
          Here is my jsp:
          <%@ page import="com.onvoy.CCPro.*" %>
          <%@ page import="java.util.*" %>
          <%
          Vector v = new Vector();
          v = (Vector)request.getAttribute("PostTitlePool");
          Enumeration enum = v.elements();
          SequenceData sq = new SequenceData();
          while(enum.hasMoreElements())
               sq = (SequenceData)enum.nextElement();
               if(sq.getIndicator()==0)
                    out.println(sq.getTitle());
               else
               out.print(sq.getTitle());
          %>
          Please explain it to me why that and how to fix it. I appreciate it very much.


I control this as follows
--> all JSP's don't create session (<@page session="false">)
--> my FrontServlet checks
session=request.getSession(false);
if(session==null)
//invoke method from LoginHandler (Helper Class)
//for check logindata and create session
else
//invoke method from ProtectedResource (Helper Class)
//for check, if user logged on
--> LoginHandler
//method UserAllowed returns true or false
if(!UserAllowed())
//invoke ServiceDispatcher method who displays
//the 'AccessDenied'Page
else
//set loggedIn into the session
session.setAttribute("loggedIn","OK");
//invoke ServiceDispatcher method to display the requested Page
--> ProtectedResource
//check if user logged in
Object o=session.getAttribute("loggedIn");
if(o==null)
//User not logged in
//invoke ServiceDispatcher method to display 'Login' Page
else
//User logged in
//invoke ServiceDispatcher method to display the requested Page
--> URL of the Application
Welcome: http://localhost:8000/APP/login.jsp
submitted FORM sent to FrontServlet
(FORM ACTION="servlet/FrontServlet")
When everything is alright (username/password)
new URL http://localhost:8000/APP/servlet/FrontServlet
and the 'Main' Page is shown
when session is timed out and i refresh page
data is sent again (without asking for username and password)and new
session is created and the 'Main' Page is shown again.
How can i fix this problem
thank you in advance :-)

Hello
Check number range assignment
Check challan update status
In the Challan Update Status report, you can create a remittance challan for various documents: Select the documents that you want to remit the tax on and choose Challan Update. The system takes you to the Create Remittance Challans program, which you then execute. However, you can only process documents for one withholding tax section at a time.
In the Bank Challan Status report, you can enter a bank challan: Select the documents (in this case identified by the internal challan numbers) that you have been sent a bank challan for and choose Bank Challan Update. The system takes you to the Enter Bank Challans program, which you then execute. However, you can only a single internal challan at a time.
In the Certificate Status report, you can print withholding tax certificates: Select the documents that you want to print a certificate for and choose Certificate Printing. The system takes you to the Print Withholding Tax Certificates program. However, you can only process documents for one withholding tax section at a time

Using Call Procedure - Urgent - Please Help

I have a login page asking users to enter id and password. From there I'm calling a jsp page which in turn calls a javabean class. The javabean class will take inputs (id and password) from the login page and pass them into an Oracle store procedure which in turn validates the id and password and returns 4 outputs: name, phone, address and log_status_code.
If log_status_code = success, the procedure will return in a
jsp page with these outputs : name, phone, address
If log_status_code = failure, the procedure will NOT return anything and users will be redirect to an error jsp page.
Could someone help me with an example? Thanks in advance.
