Java Object References

Is there any way to find out whether any java object has any active reference or not, means is it referenced till now or ready for gc. If it possible then can we get the information that from where is it referenced?

Are you trying to write a garbage collector?
The basic problem here is if you're analyzing an object to see if it's being linked to, that means that you must have an active link (unless you're outside of the application)

Java object reference index..

Hi All,
I have two doubts, it will be great if I could be suggested any thing on these.
1. Is it a good idea to create an java object in the memory, may be 1-2 Mb in size and keep it in the server for a long period? The reason is the server restart may be once in 50-60 days.
2. If the component objects(child objects... you can think of the whole object as a XML file structure), of the above mentioned object, are having a unique attribute id (type String), can I genereate an index on this attribute that will give me the reference of the object, so that I do not have to traverse the entire object to get an child object having a unique id.
Can you suggest any algorithm (number of child objects / items in the index will be 80000 - 100000) like binary indexing or hash function etc..
where in I will search the index with an unique ID (String type) and get a Object reference.
TIA
Ayusman

1. Is it a good idea to ...Based on the information you gave, it is impossible to access whether it is a good idea or bad idea. If your computer has infinite CPU and infinite memory, then it wouldn't matter if you kept 1-2 MB in memory. It comes down to 1) how much time would it take to load that information from disk 2) how much time is the end user / process that depends on the information willing to wait 3) what other resources would be competing for that memory 4) how often would that memory be accessed, in other words, what is the gain / loss of not having it in memory vs the gain / loss of having it in memory.
2. If the component objects(child objects... A hashtable would provide one possible solution. If your tree structure is likely to grow into 10s or 100s of MBs, then you may want to use a database. XML in my opinion is more of a transitional state of storing information (e.g. when the information needs to be transfered). I don't think storing a XML tree in memory is a good idea because it may not lend well to writing code to gather information.

Is down casting possible in Java objects(reference variables)?

I hope, Java up casting and down casting is possible in Java primitive variables like int float and so on.
My doubt is,Does in object of Java(reference variables) support down casting?

After spending time and effort doing that, if you still have questions, indicate clearly what you read and what part you didn't understand. The way you're doing it is NOT an effective way to learn, and it's a waste of everyone's time.

How to reference multiple instances of the same Java object from PL/SQL?

Dear all,
I'm experimenting with calling Java from PL/SQL.
My simple attempts work, which is calling public static [java] methods through PL/SQL wrappers from SQL (and PL/SQL). (See my example code below).
However it is the limitation of the public static methods that puzzels me.
I would like to do the following:
- from PL/SQL (in essence it needs to become a forms app) create one or more objects in the java realm
- from PL/SQL alter properties of a java object
- from PL/SQL call methods on a java object
However I fail to see how I can create multiple instances of an object and reference one particular object in the java realm through public static methods.
My current solution is the singleton pattern: of said java object I have only 1 copy, so I do not need to know a reference to it.
I can just assume that there will only ever be 1 of said object.
But I should be able to make more then 1 instance of an object.
To make it more specific:
- suppose I have the object car in the java realm
- from PL/SQL I want to create a car in the java realm
- from PL/SQL I need to give it license plates
- I need to start the engine of a scpecific car
However if I want more then 1 car then I need to be able to refrence them. How is this done?
Somehow I need to be able to execute the following in PL/SQL:
DECLARE
vMyCar_Porsche CAR;
vMyCar_Fiat CAR;
BEGIN
vMyCar_Porsche = new CAR();
vMyCar_Fiat = new CAR();
vMyCar_Porsche.setLicensePlates('FAST');
vMyCar_Porsche.startEngine();
vMyCar_Fiat.killEngine();
END;
Thanks in advance.
Best Regards,
Ruben
My current example code is the following:
JAVA:
===
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED CODAROUL."RMG/BO/RMG_OBJECT" as package RMG.BO;
public class RMG_OBJECT {
private static RMG_OBJECT instance = new RMGOBJECT();

private RMG_OBJECT(){
this.rmgObjectNaam = "NonDetermined";
public static String GET_RMGOBJECT_NAAM () {
String toestand = null;
if (_instance == null) {toestand = "DOES NOT EXIST";} else { toestand = "EXISTS";};
System.out.println("instance : " + toestand);
System.out.println("object name is : " + _instance.rmgObjectNaam);
return _instance.rmgObjectNaam;
public static Integer SET_RMGOBJECT_NAAM (String IN)
try
_instance.rmgObjectNaam = IN;
return 1;
catch (Exception e)//catch
System.out.println("Other Exception: " + e.toString());
e.printStackTrace();
return 5;
} //catch
PL/SQL Wrapper:
==========
CREATE OR REPLACE FUNCTION CODAROUL.SET_RMGOBJECT_NAAM(NAAM IN VARCHAR2) return NUMBER AS
LANGUAGE JAVA NAME 'RMG.BO.RMG_OBJECT.SET_RMGOBJECT_NAAM (java.lang.String) return java.lang.Integer';
Calling from SQL:
==========
CALL dbms_java.set_output(2000);
select CODAROUL.GET_RMGOBJECT_NAAM() from dual;

You can do this by manually creating a new iterator binding in your binding tab.
So instead of dragging the VO directly to the page, go to the binding tab, add a new executable iterator binding, and point to that one from your ELs in the page itself.

Why Java provides Object cloning even if there is Object reference variable

In both cases original value get changed. What is the difference between these (clonable interface & Object reference variable)

Cloneable is a way to make a copy of an object, so that you now have two objects, usually with the same state. Assigning the value in one reference variable to another variable (I can only assume that's what you're talking about, as your question is not clear at all) does not create another object.

"An error has occurred:Object reference not set to an instance of an object."

This error message comes up with a user in InfoView. The user schedules a report, updates parameters, and the report kicks off successfully. But then a few minutes later, this error is received. This occurs sporadically, regardless of the length of time of report or amount of data being retrieved. Sometimes the report runs to completion. Other times this error message occurs.
Has anyone seen this before and have any thoughts?
Thank you.
“An error has occurred:Object reference not set to an instance of an object.”

Are you able to replicate the issue both in Java and .NET InfoView?
For .NET InfoView, sometimes the "An error has occurred: Object reference not set to an instance of an object" error shows up after the .NET Framework is upgraded to 2.0

How to parse XML to Java object... please help really stuck

Thank you for reading this email...
If I have a **DTD** like:
<!ELEMENT person (name, age)>
<!ATTLIST person

</person>
**** Could you help me to write a simple parser to parse my DTD and XML to Java object, and how can I use those objects... sorry if the problem is too basic, I am a beginner and very stuck... I am very confuse with SAXParserFactory, SAXParser, ParserAdapter and DOM has its own Factory and Parser, so confuse...
Thank you for your help, Yo

Hi, Yo,
Thank you very much for your help. And I Wish you are there...I'm. And I plan to stay - It's sunny and warm here in Honolulu and the waves are up :)
A bit more question for dear people:
In the notes, it's mainly focus on JAXB,
1. Is that mean JAXB is most popular parser for
parsing XML into Java object? With me, definitely. There are essentially 3 technologies that allow you to parse XML documents:
1) "Callbacks" (e.g. SAX in JAXP): You write a class that overrides 3 methods that will be called i) whenever the parser encounters a start tag, ii) an end tag, or iii) PCDATA. Drawback: You have to figure out where the heck in the document hierarchy you are when such a callback happens, because the same method is called on EACH start tag and similarly for the end tag and the PCDATA. You have to create the objects and put them into your own data structure - it's very tedious, but you have complete control. (Well, more or less.)
2) "Tree" (e.g. DOM in JAXP, or it's better cousin JDOM): You call a parser that in one swoop creates an entire hierarchy that corresponds to the XML document. You don't get called on each tag as with SAX, you just get the root of the resulting tree. Drawback: All the nodes in the tree have the same type! You probably want to know which tags are in the document, don't you? Well, you'll have to traverse the tree and ask each node: What tag do you represent? And what are your attributes? (You get only strings in response even though your attributes often represent numbers.) Unless you want to display the tree - that's a nice application, you can do it as a tree model for JTree -, or otherwise don't care about the individual tags, DOM is not of much help, because you have to keep track where in the tree you are while you traverse it.
3) Enter JAXB (or Castor, or ...): You give it a grammar of the XML documents you want to parse, or "unmarshall" as the fashion dictates to call it. (Actually the name isn't that bad, because "parsing" focuses on the input text while "unmarshalling" focuses on the objects you get, even though I'd reason that it should be marshalling that converts into objects and unmarshalling that converts objects to something else, and not vice versa but that's just my opinion.) The JAXB compiler creates a bunch of source files each with one (or now more) class(es) (and now interfaces) that correspond to the elements/tags of your grammar. (Now "compiler" is a true jevel of a misnomer, try to explain to students that after they run the "compiler", they still need to compile the sources the "compiler" generated with the real Java compiler!). Ok, you've got these sources compiled. Now you call one single method, unmarshall() and as a result you get the root node of the hierarchy that corresponds to the XML document. Sounds like DOM, but it's much better - the objects in the resulting tree don't have all the same type, but their type depends on the tag they represent. E.g if there is the tag <ball-game> then there will be an object of type myPackage.BallGame in your data structure. It gets better, if there is <score> inside <ball-game> and you have an object ballGame (of type BallGame) that you can simply call ballGame.getScore() and you get an object of type myPackage.Score. In other words, the child tags become properties of the parent object. Even better, the attributes become properties, too, so as far as your program is concerned there is no difference whether the property value was originally a tag or an attribute. On top of that, you can tell in your schema that the property has an int value - or another primitive type (that's like that in 1.0, in the early release you'll have to do it in the additional xjs file). So this is a very natural way to explore the data structure of the XML document. Of course there are drawbacks, but they are minor: daunting complexity and, as a consequence, very steep learning curve, documentation that leaves much to reader's phantasy - read trial and error - (the user's guide is too simplicistic and the examples too primitive, e.g. they don't even tell you how to make a schema where a tag has only attributes) and reference manual that has ~200 pages full of technicalities and you have to look with magnifying glas for the really usefull stuff, huge number of generated classes, some of which you may not need at all (and in 1.0 the number has doubled because each class has an accompanying interface), etc., etc. But overall, all that pales compared to the drastically improved efficiency of the programmer's efforts, i.e. your time. The time you'll spend learning the intricacies is well spent, you'll learn it once and then it will shorten your programming time all the time you use it. It's like C and Java, Java is order of magnitude more complex, but you'd probably never be sorry you gave up C.
Of course the above essay leaves out lots and lots of detail, but I think that it touches the most important points.
A word about JAXB 1.0 vs. Early Release (EA) version. If you have time, definitively learn 1.0, they are quite different and the main advantage is that the schema combines all the info that you had to formulate in the DTD and in the xjs file when using the EA version. I suggested EA was because you had a DTD already, but in retrospect, you better start from scratch with 1.0. The concepts in 1.0 are here to stay and once your surmounted the learning curve, you'll be glad that you don't have to switch concepts.
When parser job is done,
what kind of Java Object we will get? (String,
InputStream or ...)See above, typically it's an object whose type is defined as a class (and interface in 1.0) within the sources that JABX generates. Or it can be a String or one of the primitive types - you tell the "compiler" in the schema (xjs file in EA) what you want!
2. If we want to use JAXB, we have to contain a
XJS-file? Something like:In EA, yes. In 1.0 no - it's all in the schema.
I am very new to XML, is there any simpler way to get
around them? It has already take me 4 days to find a
simple parser which give it XML and DTD, then return
to me Java objects ... I mean if that kind of parser
exists....It'll take you probably magnitude longer that that to get really familiar with JAXB, but believe me it's worth it. You'll save countless days if not weeks once you'll start developing serious software with it. How long did it take you to learn Java and it's main APIs? You'll either invest the time learning how to use the software others have written, or you invest it writing it yourself. I'll take the former any time. But it's only my opinion...

Advantages of using ejb vs java objects for pipeline components?

hi,
one of our applications is a fairly simple application. for simplicity sake, we are considering using java objects (accessing database tables) instead of ejbs for our pipeline components.
before flying with this decision, we'd like to be sure we are not missing something obvious.
please send me any references/pointers you have that summarize what the advantages of one approach (ejb vs java objects) over the other are.
thanks!

Wole, you will get a much better response posting this to

Error : Access not possible using "null" objects reference

Hello.
i am working with a zbapi.
i called a external email program in this bapi,everything is working fine over here.
In webdynpro java they mapped my bapi and starting working from there.
every functionality is working fine but regarding this email stuff it is showing an error as access not possible using null objects reference.
where could be the possible error.
is it in webdynpro or in abap side.

Raghu,
You are right. When it comes from the WD Java, may be you are not passing any value at all. You can trace it by these ways.
1. Check it using SE37, make sure everyhting is fine.
2. Print all the values that you are passing to the RFC in the execute RFC method().
3. using ST05 transaction in R/3, enable RFC and SQL trace, check what is passing in between web dynpro and R/3.
Moreover paste your error message here.
Thanks,
Raj.

Y in java objects are created on heap only and not on stack ??

Hi ,
I need a answer to the question " why all the objects are created on heap only in java and not on stack " ?
In java a object is created when we specify new i.e. for example,
consider the following cases.
1.
Vector v = new Vector();
here object is created and the reference to this object is assigned to variable v. okie.
2.
when i write something like
Vector vec ;
Here i am creating reference variable for Vector. No object is created and no seperate memory is allocated for it. Reference variablesa are stored along with other primitive variables on the java stack.
My question is, in C++ by writing case 2 i can create an object and it is creating this object on stack. So why in java object is not created on stack while i do like this ? Why in java objects are created on heap only ?
If my question is out of interest of this forum i apologize for it. But if somebody can throw some light on it, it would be of great help.
Cheers !!
Dipesh

Hi
I asked this question just to understand how compiler and jvm cud have been designed......i.e. to know the philosophy behind designing language.......
now what i cud surmise is that if objects were to be stored in stack then on calling garbage colllector , it may delete some unused obj and unreferenced object(unreachable object) and this in turn may give rise to non-contagious areas in stack, thus nullifying the garbage collector's objective of freeing the the memory. Again deallocating that intersperse spaces into one free block of space will be bit troublesome task.....
So considering above factor the designer of jvm and java compiler have opted for storing objects on heap rather than stack.....
If u have something to say bout this.......pls go ahead.......
Cheers !!

How to get caller object reference from a method

Hi,
I am working a already existing Java Swing project, now I got a problem, in a method I need to get the caller object reference otherwise, I can't succeed this operation. So please tell me a way how to get the caller object reference from a method. that method would be static or regular method anything will do for me.

Actually we have a huge project which is writen plain JAVA, so in this project the authors written the Database connection package for single database transaction. so now we are using this project source code for JSF application in this web application the DB package has serve based on the dynamic db connection parameters, so if we want to change this package fully means need to solve the dependency problem in hundreds of classes, so my point is if I can access the caller object in the DB package when ever it gets called by any class from any where of the project. So actually I liked Reflection.getcallerclass, the way of implementation perfectly works for me but it is not giving caller object reference, if something gives the caller object then I can get the DB connection parameters then there is no need to pass the parameters in the hierarchy.You can add a parameter (of type Object) to your addition() method
and everywhere you call the addition() method also pass this (which from the POW of the addition() method will be a reference to the calling class instance).
There may be alternative solutions
but none that require less effort.

Line Chart: It is possible to get the object reference from a flash chart

Hi Folks,
hope you feel well ...
I wan't to get the Object Reference from a Chart Flash Object using javascript in the HTML Header of a Apex Page.
It's long time ago with Oracle/Java and so my skills are really shity :-)
The Functionbody works, but the following error occurs: chart.refresh is not a function
It is necessary to CAST it ? with the Class AnyChart.js ?

Obtaining CORBA Object References

I have found two separate references on the Sun site to the different ways in which clients may reference CORBA objects. In each case, three methods are listed, but one item in each list seems to be different from the 'corresponding' item in the other list.
At URL http://java.sun.com/j2se/1.3/docs/guide/idl/jidlInitialization.html, the following list is given:
1. From a string that was specially created from an object reference
2. From another object, such as a naming context
3. From the ORB operation resolve_initial_references()
[Numbers added by me for ease of reference.]
At URL http://java.sun.com/j2se/1.3/docs/guide/idl/jidlUsingCORBA.html, the following list is given:
1. from a factory object. For example, the client could invoke a create method on DocumentFactory
object in order to create a new Document. The DocumentFactory create method would return an
object refererence for Document to the client.
2. from the nameservice. For example, the client could obtain an object reference for the
DocumentFactory by issuing a request on the nameservice.
3. From a string that was specially created from an object reference
Though items 1 and 2 from the first list seem to correspond closely to items 3 and 2 respectively from the second list, item 3 (list 1) and item 1(list 2) do not. Does anybody know how this apparent anomaly can be resolved and which (if either) of these lists is (more?) correct?
Thanks in anticipation.
Jan

There really is not an anomaly here. What you are indicating as an anomaly is really two distinct things.
There are always two steps here:
1. How does your client get the initial object reference to the server object(s). The list 1 comprehensively describes that. Typically the initial object references will be few.
2. Once the initial references are acquired, client can make calls using these initial references to get other object references, during the clients life time. The item 1 in list 2 is a way of doing this.
The list 1 is giving you ALL possible ways of acquiring an object reference for the very FIRST time.
Item 1 in list 2 is actually suggesting a pattern or a way or doing something. For example, if your client wishes to create multiple objects of a certain family, you can use a DocumentFactory on the server side. You would acquire initial reference to the DocumentFactory using one of the ways described in List 1. Once the client has the DocumentFactory reference, it can call create on it to create Document objects on the server side. Also, the create() method will return a reference to the Document object to the client.

Using java objects in coldfusion

I have a java object, that needs to be used in a cfm page.
The java object itself references classes from an external jar
file. I've copied the java object class, and the external jar files
in the web-inf/lib directory of coldfusion.
My java object is:
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;
import org.apache.commons.httpclient.params.HttpMethodParams;
public class TestObj{
public TestObj() {
// TODO Auto-generated constructor stub
public boolean Connect(String url)
boolean connected=true;
HttpClient client = new HttpClient();
GetMethod method = new GetMethod(url);
method.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,
new DefaultHttpMethodRetryHandler(0, false));
try {
// Execute the method.
int statusCode = client.executeMethod(method);
if (statusCode != HttpStatus.SC_OK) {
connected=false;
connected=true;
} catch (Exception e) {
connected=false;
} finally {
// Release the connection.
method.releaseConnection();
return(connected);
I'm accessing the object in the following way within the cfm:
<cfobject action="create" type="Java" class="TestObj"
name="tobj">
<cfset connctd=tobj.Connect("
http://some url...")>
I get an error '500 null' when I load this cfm. When I
comment out the code for httpclient and related objects in TestObj
and reload the page, I don't see an error. This makes me think that
httpclient is not accessible to the java object in the coldfusion
environment even though I've copied the related jar files for
httpclient and the other objects in the web-inf/lib directory.
So my question is: Can a java object, being called from a
coldfusion page, reference other java objects available in jar
files in a coldfusion environment?
Any help on this is greatly appreciated.
Thanks

Yes, my test class is in a jar.
Here's the error I'm seeing in exception.log:
