Design question: RemoteException -- checked or unchecked

I'm working an non-RMI RPC library and a question that has come up is how to deal with RPC-induced failures (networking outages, interface clashes). I'm curious what the RMI experience was with making RemoteException a checked exception. In retrospect, was this the right choice? Or should have it been unchcked? If you prefer the checked exception, is subclassing IOException still considered the correct approach?

I think Sun got it right in both cases myself. The rationale is given at some length in http://research.sun.com/techrep/1994/abstract-29.html.

To Check or Uncheck? That is the Question

In my Itunes music on my computer I have a lot of songs. I noticed that to the left of the song titles there is a check box. Some of my songs are checked and some are not, what does this mean to me? Should they all be checked or unchecked?

If you have the "sync only checked songs and videos" box checked then only the checked songs and videos will be synced.
Otherwise it will sync based on what you told it to sync.

How to change a check box default from checked to unchecked?

Hi All,
I have a form, want to change a check box default from checked to unchecked.
from the layout, doulb click into property of this check box, did not see default setting for the box, where to change a check box default from checked to unchecked?
Thanks.

hello friend,
->go to the property palette of ur check box
->under the functional set the property "check box mapping of other values"=unchecked
so...when u run the form then checkbox will unchecked.
but..at design time u can't see the effect of unchecked..

Time Zone support - checked or unchecked?

I export my iCal claendar to Entourage (for the better printouts) and noticed that some appointments were showing up in the Entourage calendar 1 hour earlier than they should. When I oen up the individual event in Entourage it has the correct time, but in Entourage's daily, weekly or monthly display, it's an hour off.
So I went back to iCal, and checked Time Zone support and made sure that every event had the correct time zone. Then I exported again, and this time Entourage had EVERY event showing at the wrong time. I've looked everywhere, and I cannot find any preference or setting with the wrong time zone checked.
I've posted a note on an Entourage forum, but my question for this forum is as far as this issue is concerned, do you think I'd be better off with iCal's Time Zone Support checked or unchecked?

There's a patch you need to run for Entourage 2004. See http://support.microsoft.com/kb/930402/en-us?spid=1720
This requires download and install of Microsoft Office 2004 for Mac 11.3.3 Update. A link to that download is contained on the page above. Be sure you get 11.3.3, because there are other versions referenced.

How to mass check or uncheck songs to be synchronized?

Holiday songs are a good example of songs some may wish to have on their iPod part of the year. I use the check/uncheck feature to have them loaded on the iPod only when I want them there. By doing this, I don't have to listen to Christmas music when going into shuffle mode. QUESTION: is there a way to mass check or uncheck a group of songs instead of doing each song one at a time? My searching has come up empty on this point.

Hello Meffley,
And welcome to Apple Discussions!
Not sure if there is way to accomplish what you are asking.
However, I can tell you that you can set these Christmas songs to "Skip when shuffling" by enabling this option for these tracks in iTunes. Just highlight all the songs you wish to have skipped when shuffling (to highlight multiple songs at once, hold down the Control key), right->click on them and choose "Get Info" from the Menu. When the window pops up, head over to the Info tab. Make sure there is a tick mark next to "Skip when shuffling." Lastly, sync the updated changes to your iPod.
When you wish to hear these songs in Shuffle Mode, go ahead and remove the tick mark and again sync the updated changes to your iPod.

Workflow design questions: FM vs WF to call FM

Hereu2019s a couple of workflow design questions.
1. We have Workitem 123 that allow user to navigate to a custom transaction TX1. User can make changes in TX1. At save or at user command of TX1, the program will call a FM (FM1) to delete WI 123 and create a new WI to send to a different agent.
Since Workitem 123 is still open and lock, the FM1 cannot delete it immediately, it has to use a DO loop to check if the Workitem 123 is dequeued before performing the WI delete.
Alternative: instead of calling the FM1, the program can raise an event which calls a new workflow, which has 1 step/task/new method which call the FM1. Even with this alternative, the Workitem 123 can still be locked when the new workflowu2019s task/method calls the FM1.
I do not like the alternative, which calls the same FM1 indirectly via a new workflow/step/task/method.
2. When an application object changes, the user exit will call a FMx which is related to workflow. The ABAP developer do not want to call the FMx directly, she wants to raise an event which call a workflow .. step .. task .. method .. FMx indirectly. This way any commit that happens in the FMx will not affect the application objectu2019s COMMIT.
My recommendation is to call the FMx using u2018in Update tasku2019 so that the FMx is only called after the COMMIT of the application object.
Any recommendation?
Amy

Mike,
Yes, in my first design, the TX can 1. raise a terminating event for the existing workitem/workflow and then 2. raise another event to call another workflow. Both 1 and 2 will be in FM1.
Then the design question is: Should the FM1 be called from TX directly or should the TX raise an event to call a new workflow which has 1 step/task, which calls a method in the Business object, and the method calls the FM1?
In my second design question, when an application object changes, the user exit will call a FMx which is related to workflow. The ABAP developer do not want to call the FMx directly, she wants to raise an event which call a workflow, which has 1 step/task, which calls a method, which calls the FMx indirectly. This way any commit that happens in the FMx will not affect the application objectu2019s COMMIT.
My recommendation is either call the FMx using u2018in Update tasku2019 so that the FMx is only called after the COMMIT of the application object or raise an event to call a receiver FM (FMx).
Thanks.

Method design question...and passing object as parameter to webserice

I am new to webservice...one design question
i am writing a webservice to check whether a user is valid user or not. The users are categorized as Member, Admin and Professional. For each user type I have to hit different data source to verify.
I can get this user type as parameter. What is the best approach to define the method?
Having one single method �isValidUser � and all the client web service can always call this method and provide user type or should I define method for each type like isValidMember, isValidAdmin ?
One more thing...in future the requirement may change for professional to have more required field in that case the parameter need to have more attribute. But on client side not much change if I have a single isValidUser method...all they have to do is pass additional values
isValidUser(String username, String usertype, String[] userAttributes){
if usertype == member
call member code
else if usertype = professional
call professional code
else if usertype = admin
call admin code
else
throw error
or
isValidMember(String username, String[] userAttributes){
call member code
One last question, can the parameter be passed as object in web service like USER object.

First of all, here is my code
CREATE OR REPLACE
TYPE USERCONTEXT AS OBJECT
user_login varchar2,
user_id integer,
CONSTRUCTOR FUNCTION USERCONTEXT (
P_LOGIN IN INTEGER
P_ID_ID IN INTEGER
) RETURN SELF AS RESULT
Either your type wont be compiled or this is not the real code..

Dreamweaver design question

Hi all. I'm new to the forum and ha da design question. My site took about 3 weeks to complete and after finishing what I though was a pretty error free website I noticed that dreamwever 8 was coming up with numerous errors that matched http://validator.w3.org's scans. My question is this. Why does dreamwever ( regardless of the release ) allow the designer of the website he/she is creating without pointing out the errors as they go along with simple instructions on how to fx them. As an example My meta tags
<META NAME="keywords" CONTENT="xxxxxxx">
<META NAME="description" CONTENT="xxxxxxxx">
<META NAME="robots" CONTENT="xxxxx">
<META NAME="author" CONTENT="xxxxxx">
<META NAME="copyright" CONTENT="xxxxxx">
all had to be changed over to
<meta name="keywords" xxxxxxxxxxxxx">
<meta name="description" CONTENT="xxxxxxx">
<meta name="robots" CONTENT="xxxxxx">
<meta name="author" CONTENT="xxxxxxxx">
<meta name="copyright" CONTENT="xxxxxxxx">
all because dreamweaver didnt tell me that the <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
didnt fit the original design. Now my site ( if you wish to view the code ) is www.gamblingwhore.com and if you look at the page source you will see that the code has been corrected on dw 8 but still shows more than 30 errors on http://validator.w3.org. Does dreamwevaer not have the basic tool available to fix these errors without such hassle. Its not just my site either, many sites built in dreamwever can be checked with the http://validator.w3.org website only to find more than 20 -100 different errors.
Dream weaver creators need to focus on these errors because they hinder seo and they create alot of extra work
Thank you

The w3c and XHTML have come a ways since the release of Dreamweaver 8 (I used it in late 2004 and 2005).
Dreamweaver 8 will build transitional XHTML files as well as old style single tag HTML. It all depends on the personal preferences of the designer.
Just for kicks, go to say... 20 random websites and see just how many get a green light when you validate them. If its half, you're lucky. This page doesn't even validate;
Dreamweaver has the menu option (at least in CS3 an CS4) under the Commands menu to "Clean Up HTML" or "Clean Up XHTML" depending on what you're building. I make a point of running that command as I build along with Apply Source Formatting.
I also use a local validator program to check my code before putting anything.
That's why they call it WYSIWYG software.
If it did everything perfectly for everyone every single time, good web designers would find themselves out of work.

Design Question: Parent/Child Distribution

Hi,
I have what I think is a straightforward design question. I tried
searching this forum for the answer, but struggled with what keywords
to use in the searches. (I also struggled with what to put on the
subject line for this post!)
Anyhow, here is my question: Given:
public class Pet {...}
public class Dog extends Pet {...}
public class Cat extends Pet {...}
public class Pig extends Pet {...}
Which is the better design?
DESIGN A:
public abstract class PetOwner {
private Pet pet;
PetOwner(Pet pet) {
this.pet = pet;
public Pet getPet() { return this.pet; }
public class DogOwner extends PetOwner {
public DogOwner(Dog dog) {
super(dog);
public class CatOwner extends PetOwner {
public CatOwner(Cat cat) {
super(cat);
public class PigOwner extends PetOwner {
public PigOwner(Pig pig) {
super(pig);
===============================================
or DESIGN B:
public abstract class PetOwner {
PetOwner() {
public class DogOwner extends PetOwner {
private Dog dog;
public DogOwner(Dog dog) {
super();
this.dog = dog;
public class CatOwner extends PetOwner {
private Cat cat;
public CatOwner(Cat cat) {
super();
this.cat = cat;
public class PigOwner extends PetOwner {
private Pig pig;
public PigOwner(Pig pig) {
super();
this.pig = pig;
This is a somewhat contrived example, so don't take it too literally.
My question is where should I put the field that holds a Pet object?
All pet owners own a pet, so should I put it in the parent class
(Design A)? Note the constructors for the child classes (e.g.
DogOwner) are designed so that the correct type of pet is checked
for. Or should each child class hold its own type of pet (Design B)?
If the answer is "it depends" (as I suspect it is), then what are
the questions I should be asking myself in order to decide?
Thanks very much, in advance!!
Chris

Design question about instant download from

Hi All,
Here is a design question for you:
Background:
The application we built is being upgraded from time to time and we send it to our users.
our users use it on a network so there is only one file to upgrade (and being done by the sys admin)
We send them a �patch�; actually, it�s a new version of the application they place it in the relevant folder and continue to work with a new version.
Problems:
1. We send them the patch via email - sometimes it takes a while until they read their email and at they are using an �old version of the system�.
2. Some of them are not computer savvy (when it�s not the sys admin) and we need to guide them as where exactly to place the file (there are 3 files)
Our (conceptual never build yet) Solution:
Build a program just like Norton antivirus (or other) that prompts the user from the task bar (next to the clock) that a new version is available and by
clicking once it will automatically download the file and store it in the correct folder.
Question:
1. Did anyone try anything like this before (or something like) who can tell me about it?
2. Do you think this kind of system will work for us?
3. Does anyone have a better solution?
Thanks
Peter

Java WebStart is the deployment technique suited for your purposes.
The deployment will be done via a webserver running a jnlp servlet (provided).
The applications may either run offline, or check online for automatic updates.
You have several configuration options.
ArgoUML and jEdit are two open source apps delivered this way.
Your app will need to be adapted though.
And your customers need an online browser with installed jvm.

Problem with checkbox checking and unchecking

Hi,
I am using JDeveloper 11.1.2.1.0.In my page i have one tab.In that i am doing inline editing which contains checkbox.When i click check box the date columns which is there should be populated according to system's date.for this to happen i have given partial triggers to those date fields and for checkbox i have given autosubmit to set true.But when i click checkbox there's coming a problem stating,
JBO-29114 ADFContext is not setup to process messages for this exception. Use the exception stack trace and error code to investigate the root cause of this exception.
Root cause error code is JBO-25009. Error message parameters are {0=java.lang.Long, 1=812D80EC6EF14B61BE1F3B6E9572FD09, 2=java.lang.String}

Hi ,
Thanks santosh,Actually when i check or uncheck date columns should be refreshed which is in that table and it should display date when its checked and it should not display date when the checkbox is unchecked.everything is working fine when i run app module but the problem which i have mentioned above is happening when i do the same in pages.
Thanks in advance

Design question: Scheduling a Variable-timeslot Resource

I originally posted this in general java programming, because this seemed like a more high-level design descussion. But now I see some class design questions. Please excuse me if this thread does not belong here (this is my first time using the forum, save answering a couple questions).
Forum,
I am having trouble determining a data structure and applicable algorithm (actually, even more general than the data structure -- the general design to use) for holding a modifiable (but more heavily read/queried than updated), variable-timeslot schedule for a given resource. Here's the situation:
Let's, for explanation purposes, say we're scheduling a school. The school has many resources. A resource is anything that can be reserved for a given event: classroom, gym, basketball, teacher, janitor, etc.
Ok, so maybe the school deal isn't the best example. Let's assume, for the sake of explanation, that classes can be any amount of time in length: 50 minutes, 127 minutes, 4 hours, 3 seconds, etc.
Now, the school has a base operation schedule, e.g. they're open from 8am to 5pm MTWRF and 10am to 2pm on saturday and sunday. Events in the school can only occur during these times, obviously.
Then, each resource has its own base operation schedule, e.g. the gym is open from noon to 5pm MTWRF and noon to 2pm on sat. and sun. The default base operation schedule for any resource is the school which "owns" the resource.
But then there are exceptions to the base operation schedule. The school (and therefore all its resources) are closed on holidays. The gym is closed on the third friday of every month for maintenance, or something like that. There are also exceptions to the available schedule due to reservations. I've implemented reservations as exceptions with a different status code to simplify things a little bit: because the basic idea is that an exception is either an addition to or removal from the scheduleable times of that resource. Each exception (reservation, closed for maintenance, etc) can be an (effectively) unrestricted amount of time.
Ok, enough set up. Somehow I need to be able to "flatten" all this information into a schedule that I can display to the user, query against, and update.
The issue is complicated more by recurring events, but I think I have that handled already and can make a recurring event be transparent from the application point of view. I just need to figure out how to represent this.
This is my current idea, and I don't like it at all:
A TimeSlot object, holding a beginning date and ending date. A data structure that holds list of TimeSlot objects in order by date. I'd probably also hold an index of some sort that maps some constant span of time to a general area in the data structure where times around there can be found, so I avoid O(n) time searching for a given time to find whether or not it is open.
I don't like this idea, because it requires me to call getBeginningDate() and getEndDate() for every single time slot I search.
Anyone have any ideas?

If I am correct, your requirement is to display a schedule, showing the occupancy of a resource (open/closed/used/free and other kind of information) on a time line.
I do not say that your design is incorrect. What I state below is strictly my views and should be treated that way.
I would not go by time-slot, instead, I would go by resource, for instance the gym, the class rooms (identified accordingly), the swimming pool etc. are all resources. Therefore (for the requirements you have specified), I would create a class, lets say "Resource" to represent all the resources. I would recommend two attributes at this stage ("name" & "identifier").
The primary attribute of interest in this case would be a date (starting at 00:00hrs and ending at 24:00hrs.), a span of 24hrs broken to the smallest unit of a minute (seconds really are not very practical here).
I would next encapsulate the availability factor, which represents the concept of availability in a class, for instance "AvailabilityStatus". The recommended attributes would be "date" and "status".
You have mentioned different status, for instance, available, booked, closed, under-maintainance etc. Each of these is a category. Let us say, numbered from 0 to n (where n<128).
The "date" attribute could be a java.util.Date object, representing a date. The "status", is byte array of 1440 elements (one element for each minute of the day). Each element of the byte array is populated by the number designation of the status (i.e, 0,1,2...n etc.), where the numbers represent the status of the minute.
The "Resource" class would carry an attribute of "resourceStatus", an ordered vector of "ResourceStatus" objects.
The object (all the objects) could be populated manually at any time, or the entire process could be automated (that is a separate area).
The problem of representation is over. You could add any number of resources as well as any number of status categories.
This is a simple solution, I do not address the issues of querying this information and rendering the actual schedule, which I believe is straight forward enough.
It is recognized that there are scope for optimizations/design rationalization here, however, this is a simple and effective enough solution.

There are no check or uncheck for the new version of iTunes?

I had just downloaded the new version of iTunes and i miss my old version. I don't see how you can check and uncheck a song to make it not play when your listening. My old version would skip the unchecked music and i miss that option. Is there an option on the new version that i'm not seeing or am i just going to have to delete them when i don't want to hear them?

In iTunes, go "Edit > Preferences". In the general tab, tick the "show list tickboxes" box, and click okay.
Have you got the wee boxes back now?

Why can't my mouse check and uncheck podcasts in iTunes 7.0.1.8?

For some crazy reason I no longer can check or uncheck podcasts with my mouse. I have to use the right-click menu to do this now. Has something changed with iTunes? This is weird.
