Best practice for displaying calling party ID

I have several different office codes in a CM 4.0. I need to prepend the area code and first two digits to the actual 5 digit extension for outgoing caller ID. I am doing this by setting External Phone Number Mask on each line and telling my route group to use that value. Is this the best way to display caller ID in this situation?

You can do this any way you want. You can check ext. ph number mask and set the mask on each phone. If you dont want to do this (too much work), you can set the prefix at the route pattern or route list level. route list level overrides route pattern level.

"Best practice" for components calling components on different panels.

I'm very new to Swing. I have been learning from tutorials, but these are always relatively simple interfaces , in which every component and container is initialised and added in the constructor of a main JFrame (extension) object.
I would assume that more complex, real-world examples would have JPanels initialise themselves. For example, I am working on a project in which the JFrame holds multiple JPanels. One of these Panels holds a group of JToggleButtons (grouped in a ButtonGroup). The action event for each button involves calling the repaint method of one of the other Panels.
Obviously, if you initialise everything in the JFrame, you can simply have the ActionListener refer to the other JPanel directly, by making the ActionListener a nested class within the JFrame class. However, I would like the JPanels to initialise their own components, including setting the button actions, by using an extension of class JPanel which includes the ActionListeners as nested classes. Therefore the ActionListener has no direct access to JPanel it needs to repaint.
What, then, is considered "best practice" for allowing these components to interact (not simply in this situation, but more generally)? Should I pass a reference to the JPanel that needs to be repainted to the JPanel that contains the ActionListeners? Should I notify the main JFrame that the Action event has fired, and then have that call "repaint"? Or is there a more common or more correct way of doing this?
Similarly, one of the JPanels needs to use a field belonging to the JFrame that holds it. Should I pass a reference to this object to the JPanel, or should I have the JPanel use "getParent()", or some other method?
I realise there are no concrete answers to this query, but I am wondering whether there are accepted practices for achieving this. My instinct is to simply pass a JPanel reference to the JPanel that needs to call repaint, but I am unsure how extensible this would be, how tightly coupled these classes would become.
Any advice anybody could give me would be much appreciated. Sorry the question is so long-winded. :)

Hello,
nice to get feedback.
I've been looking at a few resources on this issue from my last post. In my application I have been using the Observer and Observable classes to implement the MVC pattern suggested by T.PD.(...)
Two issues (not fatal, but annoying) with this are:
-Observable is a class, not an interface; since most of my Observers already extend JPanel (or some such), I have had to create inner classes.
-If an Observer is observing multiple Observables, it will have to determine which Observer called its update() method (by using reference equality or class comparison or whatever). Again, a very minor issue, but something to keep in mind.I don't deem those issues are minor. The second one in particular, is rather annoying in terms of maintenance ("Err, remind me, which widget is calling this "update()" method?").
In addition to that, the Observable/Observer are legacy non-generified classes, that incurr a loosely-typed approach (the subject and context arguments to the update(Observable subject, Object context) methods give hardly any info in themselves, and they generally have to be cast to provide app-specific information.
Note that the "notification model" from AWT and Swing widgets is not Observer-Observable, but merely EventListener . Although we can only guess what reasons made them develop a specific notification model, I deem this essentially stems from those reasons.
The contrasting appraoches are discussed in this article from Bill Venners: The Event Generator Idiom (http://www.artima.com/designtechniques/eventgenP.html).
N.B.: this article is from a previous-millenary series of "Design Techniques" articles that I found very useful when I learned OO design (GUI or not).
One last nail against the Observer/Observable model: these are general classes that can be used regardless of the context (GUI/non-GUI code), so this makes it easier to forget about Swing threading rules when using them (essentially: is the update method called in the EDT or not).
If anybody has any information on the performance or efficiency of using Observable/ObserverI would be very surprised if this had any performance impact. If it had, that would mean that you have either:
- a lot of widgets that are listening to one another (and then the Mediator pattern is almost a must to structure such entangled dependencies). And even then I don't think there could be any impact below a few thousands widgets.
- expensive or long-running computation in the update methods. That's unrelated to the notification model itself.
- a lot of non-GUI components that use the Observer/Observable to communicate among themselves - all the more risk then, to have a GUI update() called outside the EDT, see remark above.
(or whether there are inbuilt equivalents for Swing components)See discussion above.
As far as your remark 2 goes (if one observer observes more than one subjects, the update() method contains branching logic) : this also occurs with the Event Delegation model indeed: for example, it is quite common that people complain that their actionPerformed() method becomes unwieldy when the same class listens for several JButtons.
The usual advice for this is, use anonymous listeners, each of which handles the event from only one source (and generally very close in code to the definition of that source), and that simply translates the "generic" event notification method into a specific method call of a Controller or Mediator .
Best regards.

Best Practice for EJB calls from servlet?

Hi folks
I could not find general rules for making calls to an stateful EJB from the web container (e.g. from a backingBean). In some books they say it is a bad programming style calling them directly from a common servlet. The book says create first an HTTPSession Object and from there call the stateful EJB.
I'm a bit confused because, I'm missing some best practice guide from where to initiate such calls.
Can somebody please point me in the right direction?
Kind Regards
Bruno
Edited by: zajoho on Oct 30, 2008 11:14 PM

Hi Bruno,
The main issue with the combination of stateful session beans and servlets is the servlet threading model.
It is dangerous to store a stateful session bean reference in servlet instance state, since the servlet instance
can be accessed concurrently, yet a stateful session bean reference is intended to be used by only one
client.
As you point out, one alternative is to store the reference in the HttpSession. That associates the reference
with a particular client, which matches the stateful session bean programming model.

Best Practice For Display Description and getting Id from af:selectOneChoice

HI Experts,
I have a table DeptTable with the two attributes. 1) DeptId and 2)DeptName
I want to diplay List of all DeptName in <af:selectOneChoice component. and in backingbean or managedbean I want to get
corresponding DeptId for Selected DeptName in <af:selectOneChoice.
To be precise, IN UI I want to see -
Dept A
Dept B
Dept C
And in bean I want to get-
101
102
103.
If I select DeptA I want to get 101.
Therefore what is the best practice to achieve it.
Regards,

CJ,
I vote for solution 1 as it's just your use case. As you said you what to update the his_status_id and her_status_id through the by selecting a STATUSES.short_txt_descr by a drop down. This is exactly the LOV solution.
ViewLinks are used fro master detail navigation (which you don't do here) and Joining the data make it difficult to update (and you still need a LOV for the drop down box.

Best practice for displaying multiple subpanels?

I have about 20 different subpanels to display controls for different functional groups. What is considered the best way to represent these on the main front panel? For example:
- tab control with a sub-panel on each tab?
- Single subpanel using Insert/Remove methods to display the selected subpanel
(select visible panel with buttons or ring menu?)
- some other way?
Considering from both code development/maintenance point of view and user experience point of view, what do you consider the best way to implement this?
Thanks and Best Regards,

Hello,
It is hard to determine what is best for your specific type of information. In the end, they all do the same thing, but what is the best for your users? What looks the best? Which provides the easiest accessibility? Which do you find to be most intuitite? There are instances where any number of these methods might work for a particular application and would not be as good in another one. This all depends on how you would like to present the information to the user and also the level of accessibility that you would like. If there was only one best way to do this, why even give options?

Best practice for method calling on objects within a collection.

Hi guys
As you may be aware, based on my other thread here. I'm designing a card game in Java. I was hoping for some advice on the best practise on how methods should be called on a custom Object contained within a custom Collection.
I have an instance variable for the Deck class as follows: List<Card> deckWhen creating an instance of the class I use deck = new ArrayList<Card>();So I have a Deck which only holds Card objects. My question is, for the Card methods, should I call them on the Card objects after 'getting' the Cards from the Deck or should I write methods within the Deck class which handles this method calling. Code explanation is as follows:
Deck standardDeck = new Deck();I want to retrieve the suit value of a card within the deck. Is this the best way to do it this way:
standardDeck.getCardAt(50).getSuit();
//getCardAt is a method within the Deck class, getSuit() is a method within the Card classor this way:
standardDeck.getSuitForCardAt(50);
//getSuitForCardAt() is a method within the Deck class. This method calls the getSuit() method within its method body.Cheers for any help guys.
Edited by: Faz_86 on Jul 10, 2010 9:53 AM

Hey Saish
Thanks for the response.
My Card class does indeed override hashCode(), equals() and toString().
The reason I am asking a card from the deck for its Suit is simply because of the rules of the game being played. The game I made is a 'Card Shredding' game where a player attempts to remove as many cards from their hand during each turn. The first to remove all their cards is the winner.
When the game starts, two decks are created. A standard 52 card deck and an empty deck. Then 8 cards are dealt to each player and one card is dealt into the empty deck. The suit and value of the card on the empty deck called the 'shredding deck' dictates which moves are valid during each turn; The played card must match the Suit or the Value of the current card on the 'shredding deck'
For example:
Card on the empty deck = 8 of Spades
The only card from a players hand which can be removed are any Spade or an Eight of any suit.
Going back to the Deck.getSuitOfCardAtIndex(int index) , this method is needed because both the AI player and human player need to have the ability to take a look at the cards which have been added to the 'shredding deck'. Again this is because of the rules of the game. Therefore I need a method to take a look at the Suit and Value for any card in the 'shredding deck'.
Taking all this into account, so far I have the following in my Deck class. Please comment on my design so far. As you can see I've tried to follow the Law Of Demter by creating many little wrapper methods. I understand totally wh getters and setters are bad but I cannot come up with a design solution to achieve what I need to based on the rules of the game without users getters. - Any tips on this would be great.
     public Card dealCard()
          Card cardToDeal = deck.remove(0);
          return cardToDeal;
     public void addCard(Card usedCard) //This method is used to add 'used' cards to the deck.
          deck.add(usedCard);
     public Card getFaceCard() //Returns the current face up playing card
          Card faceCard = deck.get(deck.size()-1);
          return faceCard;
     public int getFaceCardValue()
          int faceCardValue = deck.get(deck.size()-1).getValue();
          return faceCardValue;
     public int getFaceCardSuit()
          int faceCardSuit = deck.get(deck.size()-1).getSuit();
          return faceCardSuit;
     public String getFaceCardName()
          String faceCardName = deck.get(deck.size()-1).toString();
          return faceCardName;
     public Card getCardAt(int position) //Returns the current face up playing card
          Card card = deck.get(position);
          return card;
     public int getFaceCardValueAt(int position)
          int cardValue = deck.get(position).getValue();
          return cardValue;
     public int getFaceCardSuitAt(int position)
          int cardSuit = deck.get(position).getSuit();
          return cardSuit;
     public String getFaceCardNameAt(int position)
          String cardName = deck.get(position).toString();
          return cardName;
     public int getDeckSize() //When recycling cards, the size of the deck is needed to determine the best time to add more cards.
          return deck.size();
     }

Best practice for displaying an image

Hello everybody,
I have an application that displays and animates several
images and I was wondering what was the best way to improve
performance.
Is it better:
- to create a Bitmap object, put it in the display list and
then move it around
- create a Sprite, do a graphics.beginBitmapFill and a
drawRect, and then animate this Sprite.
Using one method or the other doesn't make a big difference
for me, but I was wondering if there is a difference in terms of
performance and memory usage.
Does anyone know ?
Thank you.

I don't think there is currently a way to do this in Catalyst (unless you create multipe text fields). I'd suggest setting it up in Flash Builder.

Best practice for database calls from Java components?

I have a java component that encapsulates some complex database logic. In unit tests, I pass in a jdbc connection.
Is there a way to pass in a database connection from PBL for a database defined as an External Resource in an ALBPM project? That way, I can test it using the "abstract" definition in the project and know that when it is deployed to production it will use the concrete definition. And, I won't have to maintain a separate configuration of the JDBC url.
Is there a better way to do this? Or is it possible?
Thanks,
Todd

Best practice for simply invoking a web service

Best practice for exporting a dps folio so a third party can work on it?

Keen for some thoughts on the best practice for exporting a dps folio, indd files, links and all, so a third party can carry on the work. Is their a better alternative to packaging each individual indd file and sharing the folio through adobe?
I know there have been similar questions here in the past, but the last (that i've found) was updated mid 2011 and I was wondering if their have been any improvements to this seemingly backwards workflow since then.
Thanks in advance!

Nothing better than packaging them and using Dropbox to share. I caution you
on one thing as far as packaging:

Best practices for apps integration with third party systems ?

Hi all
I would like to know if there is any document from oracle or from your own regarding best practices for apps integration with third party systems.
For example, in particular, let's say we need customization in a given module(ex:payables) need to provide data to a third party system, consider following:
outbound interface:
1)should third party system should be given with direct access to oracle database to access a particular payments data information table/view to look for data ?
2) should oracle create a file to third party system, so that it can read and do what it need to do?
inbound:
1) should third party should directly login and insert data into tables which holds response data?
2) again, should third party create file and oralce apps will pick up for further processing?
again, there could be lot of company specific scenarios like it has to be real time or not... etc...
How does companies make sure third party systems are not directly dipping into other systems (oracle apps/others), so that it will follow certain integration best practices.
how does enterprise architectute will play a role in this? can we apply SOA standards? should use request/reply using Tibco etc?
Many oracle apps implementations customizations are more or less directly interacting with third party systems by including code to login into respective third party systems and vice versa.
Let me your know if you have done differently and that would help oracle apps community.
thanks
rrb.

you want to send idoc to third party system (NONSAP).
what kind of system is it? can it handle http requests
or
can it handle webservice?
which version of R/3 you are using?
what is the mechanism the receiving system has, to receive data?

Best practice for integrating oracle atg with external web service

Hi All
What is the best practice for integrating oracle atg with external web service? Is it using integration repository or calling the web service directly from the java class using a WS client?
With Thanks & Regards
Abhishek

Using Integration Repository might cause performance overhead based on the operation you are doing, I have never used Integration Repository for 3rd Party integration therefore I am not able to make any comment on this.
Calling directly as a Java Client is an easy approach and you can use ATG component framework to support that by making the endpoint, security credentials etc as configurable properties.

Best practice for including additional DLLs/data files with plug-in

Hi,
Let's say I'm writing a plug-in which calls code in additional DLLs, and I want to ship these DLLs as part of the plug-in. I'd like to know what is considered "best practice" in terms of whether this is ok (assuming of course that the un-installer is set up to remove them correctly), and if so, where is the best place to put the DLLs.
Is it considered ok at all to ship additional DLLs, or should I try and statically link everything?
If it's ok to ship additional DLLs, should I install them in the same folder as the plug-in DLL (e.g. the .8BF or whatever), in a subfolder of the plug-in folder or somewhere else?
(I have the same question about shipping additional files too, such as data or resource files.)
Thanks

I probably should have posed this question here before I delved into writing Java to get data for reports, but better late than never.
Our ERP is written in COBOL. We have a third party ODBC which allows us to access data using a version of SQL. I have several Java sources compiled in my database that access the data and return something relevant. The Java sources are written in a procedural style rather than taking advantage of object oriented programming with attributes and methods.
OO is a choice not a mandate. Using Java in a procedural way is certainly not ideal but given that it is existing code I would look more into whether is well written procedural code rather than looking at the lack of OO.
Now that I am becoming more comfortable with the Java language, I would greatly appreciate any feedback as to best practices for incorporating Java into my database.
My guess is that it would be helpful to model the ERP "tables" with Java classes that would have attributes, which correspond to the fields, and methods to return the attributes in an appropriate way. Does that sound reasonable? If so, is there a way to automate the task of modeling the tables? If not reasonable, what would you recommend?Normally you create a data model driven by business need. You then implement using whatever means seem expedient in terms of other business constraints to closely model that data model.
It is often the case that there is a strong correlation between data models and tables but certainly in my experience it is rare when there are not other needs driven by the data model (such as how foreign keys and link tables are implemented and used.)

Query Best Practice for Reports

I am new to Apex and I am wondering what is the best practice for store your sql quries for reports. I am a believer of storing all sql behind pacakge functions or procedures. And it looks like the only options for report pages are to use a direct SQL query, or a function that returns a query as a string. Yes the function method counts as putting the code in Oracle but not really. It is still getting compiled and parsed on the Apex side. It would be nice if Apex could handle a cursor but I have read that it doesn't directly. You have to have a function that returns a cursor and then create a pipelined function that calls the cursor function. That is kind of silly. Is there some other way to do this?
Apex 4.2
Oracle 11.2.0.2
Thanks for any input.
Jeff

Hi Jeff,
I'm not necessarily a believer in packaging queries. I'm a little more pragmatic in that I believe it may make sense in environments where you have a client environment that just expects a result set that is then manipulated by the client for the purposes of presentation, pagination etc. Apex has a different architecture in that the client is purely an HTML presentation layer (browser) and the presentation, pagination etc is formulated in the database along with the data using the Oracle web toolkit, which is a set of internal packages that produce HTML. Note that handling and manipulating ref cursors inside PL/SQL is not a joy, they were mainly designed to be passed out to external clients. (Often to shield programmers who don't or won't even try to understand relational concepts)
This means that when you create a report based on a query, the Apex engine will manipulate that base query, depending on the display requirements and pagination requirements of your report, before it submits that query to the database for execution. To get an idea of how this manipulation occurs, you can run your report in debug mode and check the actual query that is submitted to the database. If the query is presented as an already executed ref cursor, then the Apex engine can't execute in the way that it does. As you have already found out, the only way of using packaged queries returning ref cursors is by the use of a pipelined function, so that the Apex engine can treat the result as a normal query.
This is the architecture of Apex, and I suspect that re-engineering the Apex engine to handle ref cursors natively, as opposed to using a pipelining trick, would be a considerable change. I hope this at least helps to explain why ref cursors and Apex don't mix. I personally don't see the purpose of having an abstraction layer of packaged queries below an abstraction layer of an API such as Apex. SQL is a perfectly good API.
