Array of objects as a part of request

Hi,
I have a complex type which is a parameter of my web service's method. Is it guarantied
that the order of object will be the same on client and server side after WLS
does the deseriliazation?
For Example (Array of address objects)
Constructor of Address object takes one value – street name
If Client side:
Address[] list = {new Address(“A street”), new Address(“B street”), new Address(“C
street”)};
Can I assume that
Server side:
addressList[0] == “A street” ;
addressList[1] == “B street” ;
addressList[2] == “C street” ;
Thanks

Hi Lukas,
If you are experiencing an out of order issue with an array after it has
been "transported", then it most likely is a bug. If you have a
reproducer, please provide it to our award winning support group.
Thanks,

Hi Bruce,
thanks for the answer. You answered my question. I was wondering about the order
if there is a chance that order of submited items (array) will be different after
WLS server deseriliazation.
Thanks again,
Lukas

Calling a Procedure which has Array of Objects as arguments (from BPEL)

I wanted to pass multiple records as arguments to a stored procedure from BPEL.
We created stored procedure which takes array of Objects as arguments. I invoked it from BPEL. It was successfully compiled and deployed.

Thread use to find max and min in an array of objects??

Hello everyone,
I need to find the min and max int value in a array of Objects.
This has to be done using threads--like divide the entire array into 10 or so blocks and find the local min and max in each block., Each block is run on a thread and finally comparing them to find the global max and min.How should I do this? I am new to Java programming and in particular to threads.
Thanks for your time and patience in answering this newbie question.
JP

Hi,
if i understand your problem, you have a big array with a lot of int values and you need to create a few arrays with a part of the big one in each, next each in a thread find the max and the min, next return the max and the min of each thread and compare these max and min to obtain the globals max and min?
In that case you can create a class in which is your big array. you create a second class implementing Runnable, in its creator you put the instance of the
first class and 2 int which are the beginning and the ending index. in this class add a method run in this method you create a loop to compare the current value to the max and min values, and you replace if you need to do. In the first class you put the main where you create a few instance of the second class in a thread :
private Thread threadName = new Thread(new SecondClass(this, start, end));
Next you start all these thread:
threadName.start();
At the end of the run method of the second class you have to write your result in the max and min fields of the first class(int type, you have to create it)
Write it only if it's necessary (if the current max is > than the already existing max).
I think it's complete!
Sorry if it's not really easy to understand, I'm french, but you can answer if you have more questions.

Check this out: making a copy of an array of objects

I have an array of objects called Figs of type Figure and I am making a copy of this array called OriginalFigs so later when Figs change, I can use the original values stored in OriginalFigs.
But I found out that when values in Figs change, values in OriginalFigs also change.
I tried to store values in Vector too but even in Vector values are changing.
seems like they both are storing reference to Figs and when Figs change , they(Vector and OriginalFigs) chnage too.
Is there any way to come around this problem?
if u know then plz share with me..........

Hi,
how do you copy them - if you use the method from Object(? was it there, never use this), you will get a shallow copy - that is a new object with the same references in it - not a new object with new objects of the figures in it.
How about providing a methode in your figure-objects which can do a total copy? - This must be easy as so you know how to construct such an object efficiently.
Another way to hold a copy is to write the figures out to a stream temporarily - all objects are serializable and so they can be stored to a stream - but your figures should not have references to other parts of the program in it, because the serialisation-process tries to serialize all references the object has, that is to be serialized. If there is for exampe a link to the main JFrame in it, the serialisation process tries to store your hole program to the stream and this may be impossible - I hat this with parts of a JTree that refuse to be stored to a stream.
Hope, this will help

An array of objects

Hi,
I'm having trouble creating an array of objects to store data I'm reading in from a text file.
I have created a class called mssg, and as I read each line of the textfile in, I've created a method called setMsg that I'm using to populate the mssg object I've created.
This works fine when I use this method on a single instance of a mssg object, but when I try to use the same code on a mssg object that's part of an array, I get an exception (and one that doesn't have any friendly error text)
mssg ms = new mssg(); //this works as expected
mssg msgs[] = new mssg [msgCounter]; //I believe the exception relates to how I'm declaring the array of objects here, but the exception doesn't occur until I try to assign data to an element of the arrayThe lines below are where the problem becomes apparent. The first object 'ms' gets assigned its values as I'd expect, however, the line below that tries to assign values to a mssg object in the msgs array, and I get an exception immediately.
ms.setMsg(currMsg,mDt,mTm,mDir,mData);
msgs[currMsg].setMsg(currMsg,mDt,mTm,mDir,mData);Can anyone tell me what I'm doing wrong in terms of declaring/assigning values to an array of objects?

It's the following error: java.lang.NullPointerException
Full error text if I take my code out of a try/catch loop is:

JSTL - Array of objects?

Hi,
I am using JSTL in a JSP to access data from my MySQL database.
Thus I am looping through doing a foreach:
<c:forEach var="row" items="${rs.rows}">
<c:set var="menuId" value="${row.id}"/>
<c:set var="nextPage" value="${row.homePage}"/>
<c:set var="promptText" value="${row.prompt}"/>
<c:set var="menuType" value="${row.menuType}"/>
</c:forEach>What I would like to do is capture this in an Array of objects.
So that I can iterate through the list numerous times without
having to requery the database each time.
Thus is there a way to create an ArrayList of objects using JSTL?
Or do I need to create the ArrayList outside of JSTL and then pass it
to the JSTL?
Thanks in advance!

You seem to think that iterating through that "rs" thing somehow uses it up, so that you can't iterate through it again. That isn't the case. You can iterate through it as often as you like, as long as it's still accessible.
If your question involved using it in several different requests, then the way to deal with that is to make your "rs" be a session attribute. However you didn't say that. In fact you didn't say much of anything, you just demanded that your unstated reason for doing it wrong should be treated as if it were a good reason. I'm not inclined to look for ugly workarounds when fixing the original error would be a better strategy, so I'm not going to play along with that. If you had a good reason for bad programming then let's hear it. For all we know (remember we know very little) you may just be misunderstanding things.

Storing an array of objects?

Right... I need my table to store a series of product ID's, quantities, and serial numbers. At the moment, I'm using a column for each time, and using a StringTokenizer to retrieve them from strings such as "3;4;2;5". However, I'd like to store all 3 values in one column, so that I can store effectively an array of objects in one column field. Is this in any way possible?
Thanks
Stu

Sorry, perhaps I wasn't clear enough.
The table I am using is designed so that each row
tracks a single technical services job (I'm writing
this for a computer repair/maintenance firm). As such,
I need to track what hardware items are used/sold with
a tech services job.
At the moment I have three columns:
ProductID ProductSerial
ProductQuantity
1;2;3;4; 111;222;333;444;
5;6;7;8
The above three columns & values contain data for 4
separate sales within the job:
ProductID 1, serial 111, quantity 5
ProductID 2, serial 222, quantity 6
ProductID 3, serial 333, quantity 7
ProductID 4, serial 444, quantity 8
To generate the info for the first sale, I take the
first token of all 3 columns, and so on, and then map
them to a two-dimensional array that will look as
follows:
(assume they're all strings for now)
String[][] sales = new String[][]
new String[] { "1", "111", "5" },
new String[] { "2", "222", "6"}
}; This works as I want. However, I suspect there's a way
to condense all three of my current columns into one
column... one that I can't myself fathom, and would
greatly appreciate help for.
-fuzzy- how could I redesign the database to implement
such a thing?
All help appreciated
Stuas pointed out the design is terrible.
here is a proper design that will make your life much easier...
Table - Sale
id- Primary Key
Table - SaleItem
saleid - Foriegn Key from Sale - also part of Primary Key
productid - other part of primary key
productserial
productquantiy
so your data would look like this in these tables...
Sale
id
1
SaleItem
saleid productid productserial productquantity
1 1 111 5
1 2 222 6
1 3 333 7
1 4 444 8
as a side note i think productid is probably a spurious field.. using are using it i think as unique id... wouldn't the serial numbers be unique? I would use just them if they are...
anyway hope this helps.

Accessing data in an array of objects..

I've created the classes
public class Box
int width;
int height;
int depth;
     public Box(int a, int b, int c)
     width = a;
     height = b;
     depth = c;
     public void getWidth()
     System.out.println(width);
     public void getHeight()
     System.out.println(height);
     public void getDepth()
     System.out.println(depth);
}and this collection of boxes...
public class Collecton
     int count = 0;
     Box[] BoxCollection;
     public Collection
     BoxCollection = new Box[50]
     public recbox(int a, int b, int c)
     BoxCollection[count] = new Box(a, b, c)
     count++
     public printBoxes()
     System.out.println("Box Number = " + count);
     System.out.print("Box Width: ");
     BoxCollection[count].getWidth();
     etc...
}Now, I call this in the main code so that after each box is created, the specs of the box is printed back out onto the screen. The calling procedure works
However, only the Box Number part seems to print... the width, height and depth all don't work.
Am I accessing the data stored in the array of objects incorrectly?
Please advise.
Thanks

a b and c come from user inputs via an input/output lib... and you are sure this user input works? Perhaps you're searching in the wrong place: Do a System.out.println(a + ", " + b + ", " + c) just after getting that user input (from console?) and check the values.

Array of objects in class private data and calling overridden VIs on these objects?

Hello
I am developing part of an application using the actor framework and have run into problems.
I have a several actors and will try briefly describe them and their intended functionality. All actors are started by a Controller actor and in the actor core for the controller I have the possibility to do a lot of intiliazation etc.
Logger:
Has a message (Send Log Message) that other actors can use to write to the log. It is supposed to take a string input and a log level (error, warning, debug etc). This message chain sends data to the actor core with a user event.
The Actor Core of Logger is supposed to save the incoming message to a log, but should be able to do it in several different ways (file, database, email or whatever).
Logger Output:
Abstract class that has a dynamic dispatch vi called "Write Output" that all it's children are supposed to overwrite.
Logger Output File
Child of Logger Output and overwrites "Write Output" to save the string to a file on disk.
Problem:
I want to be able to set up the actor core for Logger once and for all but still be able to create new children of "Logger Output" and have them be handled in the Logger actor core.
My idea was to have Logger use an array of objects as private data and initialize this array in the Controller actor core.
In the logger actor core I could then auto index the array and use each element (each Logger Output child) and the abstract "Write Output" vi to get the correct functionality.
HOWEVER, I cannot get this to work properly and I think I have misunderstood something or stared myself blind on this problem. I have tried 3 different methods when it comes to private data for Logger.
1. Labview Object
2. Array of Labview Object
3. Array of Logger Output Object
Of these 3 methods, I can only get the first one to work and that doesn't accomplish what I want in the end (being able to add more classes without changing private data / actor core for Logger).
I have included 3 screenshots that show snippets of 2 of the actor cores and the private data. File names should correspond to my description above.
The screenshot "Logger actor core.png" shows a very fast test of the 3 different methods I described above. Each of the 3 tunnel inputs to the event structure can be wired to the "Reference" input of "To More Specific Class", but only method 1 (Labview Object) works.
If you need additional information / screenshots or whatever please ask.
Thanks in advance

Thanks for the reply and sorry for the confusing OP. It was meant as a quick test and a way to skip making 10+ screenshots .
I updated the actor core for the Controller and Logger to be less confusing (hopefully) and attached 2 screenshots.
I agree with you that it would be a good idea to make a message for the controller that can launch new children of the L" abstract actor, but for these tests I have just launched it the easy way (dragging it to the controller actor core).
Both Logger Output and Logger Output File are actors and in Logger Output there is a dynamic dispatch vi called Write Output that I want to override in all its children.
The problem is when I run the actor core of Logger (see the screenshot) only the abstract version (the one in Logger Output) of Write Output is executed, not the overridden version from Logger Output File.
When I did the same thing with the actor cores looking like the did in my original post, then the correct overridden version got executed when I used the method with one Labview Object in private data (not any array or an array of Logger Output objects).
EDIT: I just tried to have the Logger private data be a single Logger Output object and writing the Logger Output File to that piece of private data in the Controller and the correct Write Output override method gets called now. So apparently I have done something stupid when it comes to creating the array of Logger Output objects and writing them in the controller? The private data is in the Logger actor so I have simply right clicked and chosen "New VI for Data Member Access" and chosen "Write" for "Element of Array of Logger Output Objects".

Forwarding the array of object to servlet class

Hi
i am new to this j2ee.So please cooperate with me.

I think you need to learn the difference between "java" and "javascript"
calling session.setAttribute from a javascript function will not have the effect that you desire.
If you give all radio buttons the same "name", then request.getParameter("radioGroup") should tell you the value of the selected one.

Urgent query about copying array of objects to html item

I have an urgent query about how I can display an array of objects on a html form. The only suitable html item I can see for this is a drop down box. Ideally a combo box would be preferable but I cant find anything like this. Basically the display item needs to contain 3 columns of data and has to display a number of rows. Can anyone tell me how to copy the array of values into a drop down box?

Here is all the code from my jsp. It keeps returning null:

Displaying the contents of an array of objects

Hello All,
My Java teacher gave us a challenge and I'm stumped. The teacher wants us to display the contents of the array in the main menthod. The original code is as follows:
public class TestObjects
     public static void main ( String args[] )
          Thing[] thingArray = { new Thing(4), new Thing(7) };
}I understand that the elements of the array are objects, and each one has a value assigned to it. The following code was my first attempt at a solution:
public class TestObjects
     public static void main ( String args[] )
          Thing[] thingArray = { new Thing(4), new Thing(7) };
                                for ( int i = 0; i < thingArray.length; i++)
                                   System.out.println( thingArray );
}To which I'm given what amounts to garbage output. I learned from reading about that output that its basically displaying the memory location of the array, and the the contents of the array. There was mention of overriding or bypassing a method in System.out.println, but I don't believe that we're that far advanced yet. Any thoughts? I know I have to get at the data fields in the objects of the array, but i'm not having an easy time figuring it out. Thanks very much in advance!

Note that you're trying to print the entire array at every loop iteration. That's probably not what you meant to do.
You probably meant to do something more like
                             System.out.println( thingArray[i] );Also, note that the java.util.Arrays class has a toString method that might be useful.
To which I'm given what amounts to garbage output. It's not garbage. It's the default output to toString() for arrays, which is in fact the toString() defined for java.lang.Object (and inherited by arrays).
I learned from reading about that output that its basically displaying the memory location of the array, and the the contents of the array.It displays a default result that is vaguely related to the memory, but probably shouldn't be thought of us such. Think of it as identifying the type of object, and a value that differentiates it from other objects of the same type.
By the way I assume you mean "+not+ the contents of the array" above. If so, that is correct.
There was mention of overriding or bypassing a method in System.out.println, but I don't believe that we're that far advanced yet. Any thoughts? No, you don't override a method in println; actually methods don't contain other methods directly. You probably do need to override toString in Thing.
I know I have to get at the data fields in the objects of the array, but i'm not having an easy time figuring it out. You can get to the individual objects in the array just by dereferencing it, as I showed you above.
But I suspect that won't be sufficient. Most likely, Thing doesn't have a toString method defined. This means that you'll end up with very similar output, but it will say "Thing" instead of "[Thing" and the numbers to the right of the "@" will be different.
You'll need to override the toString() method in Thing to get the output you want.

Error: Path to object does not exist at Request

Hi experts,
i have a scenario asynchronous/syncrhonous: file to rfc and get back response rfc to other file. I have 3 communication channel: 1 sender file, 1 receiver file, 1 receiver RFC. The communication channel sender file show the follow error:
Attempt to process file failed with com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Path to object does not exist at Request, the whole lookup name is localejbs/AF_Modules/Request/ResponseBean.
I do not understand how modules(AF_Modules/Request/ResponseBean) in adapter works, the documents that I have found I am not much has clarified, could someone please explain and tell me something's error?
very thanks,
regards

Hi,
Check the receiver agreement, you might have configured the file receiver communication channel name instead of the RFC receiver communication channel name.
Also check the module parameters in the sender file CC
Processing sequence:
Module name                                           Module type                               Module key

CallSapAdapter                                       Local Enterprise Bean                       2
AF_Modules/ResponseOnewayBean         Local Enterprise Bean                       3
Module configuration:

3                                            receiverChannel                            <File receiver CC>

How to pass a array of object to oracle procedure using callable

Hi,
I am calling a oracle stored procedure using callable statement which has IN and OUT parameter of same type.
IN and OUT are array of objects. (ie) IN parameter as Array of Objects and OUT parameter as Array of Objects
here are the steps i have done as advised from oracle forum. correct me if i am in wrong direction
ORACLE types and Stored Procedure
CREATE OR REPLACE
TYPE APPS.DEPARTMENT_TYPE AS OBJECT (
DNO NUMBER (10),
NAME VARCHAR2 (50),
LOCATION VARCHAR2 (50)
CREATE OR REPLACE
TYPE APPS.DEPT_ARRAY AS TABLE OF department_type;
CREATE OR REPLACE package body APPS.insert_object
IS
PROCEDURE insert_object_prc (d IN dept_array, d2 OUT dept_array)
IS
BEGIN
d2 := dept_array ();
FOR j IN 1 .. d.COUNT
LOOP
d2.EXTEND;
d2 (j) := department_type (d (j).dno, d (j).name, d(j).location);
END LOOP;
END insert_object_prc;
END insert_object;

You posted this question in the wrong forum section. There is one dedicated to Java that was more appropriate.
Anyway here is a link that describes what you should do.

Property List error: Unexpected character b at line 1 / JSON error: JSON text did not start with array or object and option to allow fragments not set.

Hi,
I have a MBP 13' Late 2011 and Yosemite 10.10.2 (14C1514).
Until yesterday, I was using Garmin ConnectIQ SDK and all was working fine.
Yesterday, I've updated my system with latest security updates and Xcode updates too (Version 6.2 (6C131e)).
Since, I can't launch the ConnectIQ simulator app, I have this message in console :
8/04/2015 15:19:04,103 mds[38]: There was an error parsing the Info.plist for the bundle at URL Info.plist -- file:///Volumes/Leto/connectiq-sdk-mac-1.1.0_2/ios/ConnectIQ.bundle/

I guess it is a normal format but my system seems to be unable to read binary plist ?
I tried some stuff with plutil
plutil -lint Info.plist
Info.plist: Unexpected character b at line 1
Same for convert
plutil -convert xml1 Info.plist
Info.plist: Property List error: Unexpected character b at line 1 / JSON error: JSON text did not start with array or object and option to allow fragments not set.
I also try to download a fresh version of the connectIQ SDK and no changes.
Any idea ?
Thanks

Step by step, how did you arrive at seeing this agreement?
