Which Constructor Is Being Called?

Can someone please tell me which constructor is being called in the example below:
public abstract class SuperClass{
public SuperClass(String a){ /* constructor code */}
public class SubClass extends SuperClass{
public SubClass(String a){super(a);}
public SubClass(String a, String b){super(a); this.b = b;}
If I call SubClass(String a, String b), then does the "super(a)" refer to the SubClass(String a) constructor or the SuperClass(String a) constructor?
Thanks for the help,
Chris

super(a) refers to the superclass this(a) refers to the subclass

Which method is being called?

Hi,
I have the foll. setup:
class A{
func1();
func2(){
func1();
class B extends A{
func1(); // over-ridden
super.func2();
So, when super.func2() is called, and A.func2() is executed, within it does A.func1() get called or does B.func1() get called. If A's method gets called how can I change it to call B's method instead?
Thanks.

Write up a quick test case. You can easily find this out for yourself.

Is there a dialing app which places icons on the screen along with the name being called?

Does anyone know of an app which places a limited number of phone numbers along with the name of the person being called on the screen of the iPhone? Our grandfather is 95 years old, and can not operate the small buttons on most cell phones, and has trouble navigating around the phone to make calls. We just want 3 phone numbers displayed, along with who is being called, so he does not have to navigate to anything except the main screen. Thanks.

Type's constructor function is called as many times as there are attributes

The constructor method for object types is being called multiple times by SQL when using the constructor in an SQL insert statement. For example, if I create an object type called TEST_O, and an object table TEST_OT based on type TEST_O, and then insert into TEST_OT using the constructor:
INSERT INTO TEST_OT VALUES ( TEST_O( TEST_ID_SEQ.nextval, 'Test', USER, SYSDATE ) );
The contructor is actually called 5 times by SQL. Here's a sample type, table, type body, and anonymous PL/SQL procedure that reproduces this error:

Hi
I got surprise issue while testing my Oracle code . Let me explain first the environment detail . Our appliaction built on
Java/J2EE(Weblogic) and backend is Oracle 11g re2 . While calling from java it call thru different user which have been provide
synonym and exectue option for corresponding procdure ,
I created on package EXTRACT_CUSTOMER_INFO_PK which will exract data to text file using UTL_FILE ( direcory , UTL_FILE grant is provided to DB user).
Now this package has been called from rp_execute_procedure_pr -- Here I is the code
CREATE OR REPLACE PROCEDURE RP_EXECUTE_PROCEDURE_PR
i_atlas_job_schedule_fk IN atlas_job_schedule.atlas_job_schedule_pk%TYPE,
i_job_id IN atlas_job.job_id%TYPE,
i_parm_value IN atlas_job_schedule.parm_value%TYPE,
o_status_code OUT NUMBER,
o_status_mesg OUT VARCHAR2
IS
-------Other old code which is not relevent for this issue ----
--------Other old code which is not relevent for this issue ----
----Below code I added ----
ELSIF l_job_id = 'CUST_EXTRACT' THEN
EXTRACT_CUSTOMER_INFO_PK.customer_report ( i_parm_value ,
o_status_code,
o_status_mesg ) ;
-- o_status_code := -99999999;
--o_status_mesg := 'PARTHA PARTHA PARTHAcess terminated!';
ELSE
o_status_code := -20300;
o_status_mesg := 'Job Id : ' || l_job_id || ' NOT found. Process terminated!';
END IF;
update_log_auto
ajs_rec.atlas_job_schedule_pk ,
'Processing End Time (GMT): '
EXCEPTION
WHEN eProcError THEN
o_status_code := SQLCODE;
o_status_mesg := SUBSTR(vMsg ||'-'||SQLERRM, 1, 200);
WHEN OTHERS THEN
o_status_code := -20300;
o_status_mesg := SUBSTR(SQLERRM, 1, 200);
update_log_auto
ajs_rec.atlas_job_schedule_pk ,
'Error : '||SQLERRM||' '
update_log_auto
ajs_rec.atlas_job_schedule_pk,
'Processing End Time (GMT): '
END RP_EXECUTE_PROCEDURE_PR;
Now It compiled sucesfully . And while I did SIT then RP_EXECUTE_PROCEDURE_PR run fine and extracted txt file . But while I called it from Java procedure It gives us error like
Error : ORA-06508: PL/SQL: could not find program unit being called 02-AUG-2012 13:16:51.
As I told RP_EXECUTE_PROCEDURE_PR old proc and used by other proc , So I first suspect issue is newly added code or may be some grant or synonym ( Although it should not be )
so I created public synony amd gave execute grant to my pkg to public .
But it repeat same error .
I did lot of R&D on my pkg but nothing happen . Finally I remane my new pkg RP_EXTRACT_CUSTOMER_INFO_PK and it works fine
I need to know what is the RCA for it . I donot think any dependecy issue as renaming pkg is working fine .
NB my DB user is iATLAS and Javauser is SUDEEP
Thanks in Advance
Debashis Mallick

First of all If i run the main procedure in like below in my Schema it is working fine
begin
-- Call the procedure
rp_execute_procedure_pr(i_atlas_job_schedule_fk => :i_atlas_job_schedule_fk,
i_job_id => :i_job_id,
i_parm_value => :i_parm_value,
o_status_code => :o_status_code,
o_status_mesg => :o_status_mesg);
end;
So thre is no question of parameter .... or Invalid state etc . If it is parameter or Invalid state issue it will give other error.
Here problem is not syntax issue .
let me give u more detail regards this issue
1.. All objects corresponding to procedure all Valid
2.. If I test on the proc on my schema like above code . It works fine
3.rp_execute_procedure_pr is a old procudere which called for differner report generartion based on parameter passing . Also as extract_customer_info_pk called with in rp_execute_procedure_pr So there is no question of synonym or privilage issue for new procedure.
4. Suprising thing is if I rename and recreate package like extract_customer_info_pk _1 or rp_extract_customer_info_pk . Which are exactly same as extract_customer_info_pk and replace those new one with extract_customer_info_pk then it work fine in my java application
I think I make it clear the issue

Finalize() method being called multiple times for same object?

I got a dilly of a pickle here.
Looks like according to the Tomcat output log file that the finalize method of class User is being called MANY more times than is being constructed.
Here is the User class:
package com.db.multi;
import java.io.*;
import com.db.ui.*;
import java.util.*;
* @author DBriscoe
public class User implements Serializable {
    private String userName = null;
    private int score = 0;
    private SocketImage img = null;
    private boolean gflag = false;
    private Calendar timeStamp = Calendar.getInstance();
    private static int counter = 0;
    /** Creates a new instance of User */
    public User() { counter++;
    public User(String userName) {
        this.userName = userName;
        counter++;
    public void setGflag(boolean gflag) {
        this.gflag = gflag;
    public boolean getGflag() {
        return gflag;
    public void setScore(int score) {
        this.score = score;
    public int getScore() {
        return score;
    public void setUserName(String userName) {
        this.userName = userName;
    public String getUserName() {
        return userName;
    public void setImage(SocketImage img) {
        this.img = img;
    public SocketImage getImage() {
        return img;
    public void setTimeStamp(Calendar c) {
        this.timeStamp = c;
    public Calendar getTimeStamp() {
        return this.timeStamp;
    public boolean equals(Object obj) {
        try {
            if (obj instanceof User) {
                User comp = (User)obj;
                return comp.getUserName().equals(userName);
            } else {
                return false;
        } catch (NullPointerException npe) {
            return false;
    public void finalize() {
        if (userName != null && !userName.startsWith("OUTOFDATE"))
            System.out.println("User " + userName + " destroyed. " + counter);
    }As you can see...
Every time a User object is created, a static counter variable is incremented and then when an object is destroyed it appends the current value of that static member to the Tomcat log file (via System.out.println being executed on server side).
Below is the log file from an example run in my webapp.

It really does seem to me like finalize is being called multiple times for the same object.
That number should incremement for every instantiated User, and finalize can only be called once for each User object.
I thought this was impossible?
Any help is appreciated!

Thanks...
I am already thinking of ideas to limit the number of threads.
Unfortunately there are two threads of execution in the servlet handler, one handles requests and the other parses the collection of User objects to check for out of date timestamps, and then eliminates them if they are out of date.
The collection parsing thread is currently a javax.swing.Timer thread (Bad design I know...) so I believe that I can routinely check for timestamps in another way and fix that problem.
Just found out too that Tomcat was throwing me a ConcurrentModificationException as well, which may help explain the slew of mysterious behavior from my servlet!
The Timer thread has to go. I got to think of a better way to routinely weed out User objects from the collection.
Or perhaps, maybe I can attempt to make it thread safe???
Eg. make my User collection volatile?
Any opinions on the best approach are well appreciated.

How to find out which queries are being used ?

We have a number of InfoSet Queries which the users are calling from SQ00. Some of them are very old.
I would like to find out which queries are being used, so we can have the idle queries decommissioned.
How can this be done ?
Best regards,
Peter

Hi,
It's been a while since I've done this but one method is to use ST03N & look for the execution of programs with an AQ* prefix. The general structure is AQZZ/<query user group><query name>.
You could probably get the same info from the audit log but I've not checked that.
Cheers,

Purchase order ME_PROCESS_PO_CUST not being called

Hello,
I've created an implementation of ME_PROCESS_PO_CUST, which is automatically migrated to Enhancement (I'm in Netweaver 2004s).
Then I go to ME21n and the badi is not being called. It is active, I have breakpoints inside the various methods, and I can create a PO from start to finished without opening debug mode.
Is there any problem with ME_PROCESS_PO_CUST in ECC 6.0?

hi,
goto se18 and give definition name and click display button.
if "multiple use" check box is not checked means it is a single use.
that means for the standard badi definition can any number of implementations,
but only one will be in active state others in inactive mode.
u can check all the detail by goingin se18 -> implentation menu->overview
if implementation is active it will glow in yellow color.all other inactive in blue color (description color).if u want u code to execute go to others and press(shiftf8) to make others inactive then come to ur code and make it active ctrlf3.
then it will work.this is for single use.
for multiple use system will predict its sequences. we abaper no need to worry of the sequences.because if it is multiple use all implementation are in active stage .so all the code will work in some sort of order.
thanx

How do I identify which control is being hovered over?

Hello all,
I have a simple feature of my code I am working on. I want to have a detailed help box ( a little more detailed than the tooltip popup option) with instructions I want to print on my screen.
The idea is that when I have an active control, the instructions will print in a small text box to give people guidance on my program.
This works for half of what I want to do.
But in the case of a custom toolbar, I do not have that ability since I cannot click inside of it like a textbox.
I am using the tooltip, but I would like to be able to print a better, more detailed message in my help box.
Ideally what I would like to know if there is a function to be able to get which control is being highlighted or hovered over by panel and control id.
It's no big deal if there isn't one, but now I am curious.

if EVENT_GOT_FOCUS is not suitable for you another possibility could be to use a timer callback, and for every timer tick call GetRelativeMouseState (panel, 0, &x_coordinate, &y_coordinate, NULL, NULL, NULL); this will return the current position of the mouse cursor on the panel. To make use of it, at the beginning of your program you need to obtain the positions of your UI controls, e.g. using GetCtrlBoundingRect ( panel, control, &button.top, &button.left, &button.height, &button.width ). Then you need to check if the mouse is within a bounding box by comparing the mouse coordinate with the control coordinate...
But why are the tooltips not working for you?

Async Interface being called synchronously via Web service/SOAP

Hi,
I have an asynchronous interface to receive data into XI which is being sent to a file system, I can successfully use this interface to send data to XI using the file sender communication channel, and the monitoring shows the same as asynchronous.
The problem is when i want to use the same setup to send data from a .Net client using SOAP/Web service. This time if I go to monitoring I get to see that the call is synchronous..????... which is quite baffeling...
I am not calling the XI webservice in synchronous mode I am calling the BeginInvoke method thus making an async call.
what is it that I have to do to get the interface to behave as async on being called from a webservice?
Thanks

Thanks guys. I do understand that this is a old post. However I cannot find the following information. I too have C# Web App call SAP PI BAPI web service getting [NullReferenceException: Object reference not set to an instance of an object.]

Cannot reference this before supertype constructor has been called

I'm confused. I would like it easier for a user to use a class where one item can be determined from another, but I'm having a problem with the constructors.
First, one constructor that works fine:
    public UndirectedGraph(List nodes, List edges) {
        this(nodes, edges, 100, 100, true, false);
    }which then calls the ultimate constructor that accepts all those other parameters.
The problem is with this one:
    public UndirectedGraph(List nodes) {
        this(nodes, collectEdges(nodes), 100, 100, true, false);
    }collectEdges returns a List of Edges, so technically all should be fine. However, this won't compile, with the message:
UndirectedGraph.java [37:1] cannot reference this before supertype constructor has been called
        this(nodes, collectEdges(nodes));
                           ^
1 error
Errors compiling UndirectedGraph.Is there a workaround for what I'm trying to do? It'd be a lot easier to have this collectEdges() method in this single place than in any class that's using this one.

You HAVE to call the super constructor before you do anything else in the constructor. You can make calls to this but the final constructor to be executed has to make the super call. I am assuming you are subclassing something here because this should not show up as an error if there is a default constuctor. The reson for this is that a subclass is built on top of its parent classes meaning it can access information in them methods in them etc. Even in the constrcutor it can do this so the super class MUST be created before the subclass.

REMOVED_FROM_STAGE Being Called on Instantiation

Hello,
I've got an interesting predicament here. I've got a MovieClip called GameOptions, and within that MovieClip, there's is another MovieClip called DifficultyButtons which subclasses RadioGroup. DifficultyButtons contains a few MovieClips called Easy Medium and Hard which are all subclassing RadioButton. While GameOptions is being added through addChild(), the child clips are all part of GameOptions built in Flash. So this is my structure:
GameOptions
-- DifficultyButtons
-- -- Easy
-- -- Medium
-- -- Hard
Now I have an event listener listening for REMOVED_FROM_STAGE in the RadioGroup and RadioButton classes. For some reason, REMOVED_FROM_STAGE is being called immediately on instantiation. Here's a (stripped down for readability's sake) version of RadioGroup:
package radiobuttons
     import flash.display.MovieClip;
     import flash.events.Event;
     import flash.events.MouseEvent;
     public class RadioGroup extends MovieClip
          public function RadioGroup()
               addEventListener(Event.ADDED_TO_STAGE, addedToStage);
          protected function addedToStage(e:Event):void
               removeEventListener(Event.ADDED_TO_STAGE, addedToStage);
               addEventListener(Event.REMOVED_FROM_STAGE, removedFromStage, false, 0, true);
               addEventListener(MouseEvent.MOUSE_UP, processClick);
          protected function processClick(e:MouseEvent):void
               trace("Click: " + e.target);
          protected function removedFromStage(e:Event):void
               trace("Removed: " + e.target);
               removeEventListener(Event.REMOVED_FROM_STAGE, removedFromStage);
               removeEventListener(MouseEvent.MOUSE_UP, processClick);
So why is it that removedFromStage is being called instantly? The clip is still there on the stage, and if I remove the event listener for REMOVED_FROM_STAGE, everything functions fine.
Also, when removedFromStage is called, it traces "Removed: [object DifficultyButtons]".
Is this because I'm not adding these clips through code, as opposed to how its done now where it's prebuilt in flash? Or is this some weirdness with me sublcassing something directly in the flash library's Export for ActionScript panel?
ps; this has nothing to do with useCapture as I've tried both.
pps; this is happening on both the DifficultyButtons and Easy/Medium/Hard.
Thanks!

So doing some more debugging, DifficultyButtons is the target and currentTarget of the REMOVED_FROM_STAGE event, and the EventPhase for this event is AT_TARGET. So it's definitely this class doing this.
Also, I tried removing the DifficultyButtons from its parent movie clip and adding it through addchild in the parent clip and still am receiving the same problem!\
edit: More trying to figure this out. I removed all references to any additional objects from GameOptions. So now my document class is doing one thing and one thing only: addChild(new GameOptions());
My GameOptions has only this code:
package hud
     import flash.display.MovieClip;
     import flash.events.Event;
     public class GameOptions extends MovieClip
          public function GameOptions()
               addEventListener(Event.ADDED_TO_STAGE, addedToStage);
          protected function addedToStage(e:Event):void
               addEventListener(Event.REMOVED_FROM_STAGE, removedFromStage);
          protected function removedFromStage(e:Event):void
               trace("I'm a game options" + this);
And, as expected, it IS tracing the trace in removedFromStage.
So... am I completely confused by the point of REMOVED_FROM_STAGE??

Recording which articles are being read

I want to create a cloud tag of popular topics
What i need to work out
1. How to record which articles are being read
2. How to display these in a tag cloud
3. Then when a user clicks on a tag - all the articles which
similar
tag are displayed
What i have done so far (how am i going?)
Db called tags
Tables
tag, article title, article url, article description
# each article has a few different tags
e.g
article for preventing std has the following tags
std, sex, safe sex, HIV
# the article itself doesnt exist in the database as i read
this
wasn't good for SEO. so the article itself exists on a static
page.
I have close to 100 medicla articles and add about 4 or 5 a
month
so i would love to get this working to save me time and
effort.
Many thanks

Have been using this code from the pete frei tutorial - cloud
tags -. It is working fine.
In the case of my database, each article has 3 tags
associated.
So there are 3 fields as opposed to 1 from which to count the
tags.
How could I adjust the code to take accountfor this?
Also I am a begineer so if you had the time to provide a
short explanation that would also be great.
<cfquery datasource="cart" name="tags">
SELECT COUNT(tag) AS tagCount, tag
FROM list
GROUP BY tag
</cfquery>
<cfset tagValueArray =
ListToArray(ValueList(tags.tagCount))>
<cfset max = ArrayMax(tagValueArray)>
<cfset min = ArrayMin(tagValueArray)>
<cfset diff = max - min>
<cfset distribution = diff / 3>
<style type="text/css">

</style>
<cfoutput query="tags">
<cfif tags.tagCount EQ min>
<cfset class="smallestTag">
<cfelseif tags.tagCount EQ max>
<cfset class="largestTag">
<cfelseif tags.tagCount GT (min + (distribution*2))>
<cfset class="largeTag">
<cfelseif tags.tagCount GT (min + distribution)>
<cfset class="mediumTag">
<cfelse>
<cfset class="smallTag">
</cfif>
<a href="/tag/#tags.tag#"
class="#class#">#tags.tag#</a>
</cfoutput>

C# Constructor being called multiple times when I run my VI

Hi all,
We are runing LabVIEW 8.51 in the lab and have been using a bodged together C++ DLL which was crude but got the job done. Now looking at rewriting it in C# to make it easier to maintain and support long term.
Ive got the C# DLL appearing in Labview and can happily call my test functions from the VI to prove both the DLL inputs and outputs are working fine (the simple input a number, add 1 and return result type of code).
However, this DLL will end up managing a Serial port connection so the contstructor must only be called once as its responsible for making my .net serial port object. Ive added a text log message in the constructor and have found that just running the VI is causing the constructor to be called at least 5 times a second. There is no user input causing this....just running the VI.
Both VI and C# source is attached.
Any ideas folks? Im a complete newbie at LabVIEW having taken this on from another developer.
The VI is in \Release and this is where the Log file is generated.

Ummmm.. yes, loop. That big thing gray rectangle that surrounds your code. Have you done any LabVIEW tutorials? That isn't even a LabVIEW question, but a basic programming question.
To learn more about LabVIEW it is recommended that you go through the introduction material, tutorial(s), and other material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. There are also several Technical Resources. You can also take the online courses for free.
