Help me with a simple CMR - please!!

Hi!
Please Im pretty new to CMR and appreciate if you
could help me answer a simple question.
Database model:
WriterTbl
ID___ Name
1____RodJohnson
2____PankajKumar
BookTbl
FK___Name
1____J2EE-DesignAndDevelopment
1____ProfessionalJSP
2____J2EESecurity
Question:
I ve two CMP entities: WriterBean and BookBean
I ve set the relations between Writer and Books, and
it works as far as a writer only has one book.
That because I set the FK also as a PK to the
BookBean. And when I try to create next book for a
writer it fails with duplicate-exception, logicaly.
Can I solve this without any need of specifing a
primary key for books at all?I dont see how. In your AS you would have had to specify either a primary key or primary class or unknown Object as primary key.
How is CMP handling no-pk entity and is relations
working without any pk?Using s1as l have found out that l if you do not specify a primary key on creation of entity bean, the ejbCreate returns null as the primary key which causes an EJBException.
Why? Cos I think a primary key has to be returned at the same time as the handle to the entity bean is stored in the Context. Why it would not insert the data first then request a primary key l dont know. I must say that this happens when you try to use autoincrement in the primary key column.
Do EJB vendors manage no pk ejbs? what about ejb
restrictions.
Reading the specification literature gives the impression that they do, but practice is another thing entirely.
I ve read that there must be a primary key, but not
necessery a database field - HOW? could you please
explain!
That the theory. When you find the answer to HOW(?), please let us know.

Please this is very urgent and I Thank you very much!!

Help me with a simple function please!

Hi,
I want to pass to a function an error number ( define by me) get the error message associated to this number in another table, and then use this message in raise_application_error...
something like
CREATE FUNCTION GetErrorMsg ("-20000") Return Error_Msg
Begin
Select Error_Msg from Error_table Where Error_Number= "-20000" ( the number sent by my function)
End;
and then
raise_application error (-20000,Error_Msg)
Thanks for any hint...
Pete

It will be like below:
CREATE FUNCTION GetErrorMsg (Perr_No Number) Return Error_Msg
Begin
Select Error_Msg from Error_table Where Error_Number= Perr_No ( the number sent by my function)
End;
and then
raise_application error (-20000,Error_Msg)
Hope this will solve your problem

Can you help me with mouse pressed method please?

hi
can you help me with my problem please, player label doesn't show up in the applet and the draw string method it doesn't draw any strings like X or O for the game I don't know what is the problem maybe it is with MousePressed method which is in Board class.

Put the incremental numbering between several code blocks. Check the log output. You will surely be able to find out till what point ur code is Ok.

I need help with a simple task (PLEASE HELP)

hi, you know how you can make a button and link it to a
different site with the actionscript in this program? well I need
to know of a way like...to make a button and...link it to the next
frame. ok, heres what im trying to make happen...the user presses a
button in the flash program thing and a comment apperars. then they
press it another time and a new one come up...and so on...I could
make like 50 different frames with new comments on them and then
make the button on each frame link to the next frame. is there a
way to do that? if there is I REALLY need your help. please
thanks :)

no need to modify anything - look at the first code:
on (release) {
nextFrame();
that's all you need on the button.
If you want it to happen on click and not release:
on (press) {
nextFrame();

Please help me with a simple flash game problem

I am trying to learn how to make flash games with Adobe flash 5.5. I am doing a tutorial from a book and am stuck.
The game is called concentration and you are suppose to match 2 tiles of the same shape. there are 10 shape tiles
and 1 question mark tile. These tiles are held in an array. 20 tiles are suppose to be displayed 5 to a row with 4 rows
and the question mark is suppose to be up on all 20. My problem is I get a blank screen when I test the movie. I
think the code is good but I beleive I have not uploaded the tiles right. I did upload the 11 tiles to the library and have
those 11 tiles and tile_movieclip in the library. Here is the code:
package {
// importing classes
import flash.display.Sprite;
// end of importing classes
public class Main extends Sprite {
public function Main() {
// variables and constants
const NUMBER_OF_TILES:uint=20;
const TILES_PER_ROW:uint=5;
var tiles:Array=new Array();
var tile:tile_movieclip;
// end of variables and constants
// tiles creation loop
for (var i:uint=0; i<NUMBER_OF_TILES; i++) {
tiles.push(Math.floor(i/2));
trace("My tiles: "+tiles);
// end of tiles creation loop
// shuffling loop
var swap,tmp:uint;
for (i=NUMBER_OF_TILES-1; i>0; i--) {
swap=Math.floor(Math.random()*i);
tmp=tiles[i];
tiles[i]=tiles[swap];
tiles[swap]=tmp;
trace("My shuffled tiles: "+tiles);
// end of shuffling loop
// tile placing loop
for (i=0; i<NUMBER_OF_TILES; i++) {
tile=new tile_movieclip();
addChild(tile);
tile.cardType=tiles[i];
tile.x=5+(tile.width+5)*(i%TILES_PER_ROW);
tile.y=5+(tile.height+5)*(Math.floor(i/TILES_PER_ROW));
tile.gotoAndStop(NUMBER_OF_TILES/2+1);
// end of tile placing loop
Can someone please explain to me what I am suppose to do to make the this work? I beleive the problem is it doesnt know where the tiles are.
Thanks.

To create the tiles, draw 10 distinct shapes in the first 10 frames of your symbol, and
the back of the tile in the 11th frame. You are free to draw them as you want, but I suggest you make them as 90 pixels squares with registration point (starting x and y position) at 0, because these are the properties of the tiles used in this chapter's
examples. At least, they should all be the same size.
It didnt say put in a library. It is saying to draw them in frames of symbol but it didnt walk me through that. Can you guide me through this? I also was looking at how to add the link identifier but it said I need a popup window but I cant see one. I thought that was done
when I went to insert new symbol. It said something about actionscript linkage. I am familliar with perl, java and c++ so I can follow the code so far but I dont have much understanding of the flash interface. I made the 10 shape tiles and the 1 question mark tile
in paint. They are .jpeg images.

Help with a simple question-please

Forgive me if this has been covered already, it seems like such a simple request but I can not find any simple answers...
I am currently using the trial version of acrobat 9.. I am considering buying. I want to create fillable PDF forms(for personal use). When I fill them them out I want to be able to email the filled out form, and save a copy of the filled out form. Can I do this? If yes how?
Basically, i want to take all my personal forms that I now send out via snail mail(some are order forms, some are claim forms that I send to my insurance co, etc...). I want to make them into fillable pdf's so i can fill them out on my computer and then email them to whoever I choose. Can I do this? How?

Do you want them to be filled0in with Reader, or Acrobat? To create a form in the first place, you'll need Acrobat. Once you've added the fields and entered the form data, you just have to save it as a new document. You can then attach the document to an email as you would any other type of file. You can also set up a "submit" type button to partially automate the process of saving and attaching a document to an email.
If you want to create a form that Reader users can fill-in and save, you will have to Reader-enable the document. In Acrobat 9, you do this by opening the document in Acrobat and selecting "Advanced > Extend Features in Adobe Reader...".
Regarding locking the document, you cannot do it securely with Reader, but you can set up the form so that the fields are set to read-only after it is filled-in but before it is saved. This may require a bit of programming in JavaScript, but it's not too complicated.

Please help me with somewhat simple problems

Hi,
I'm being asked to produce a 90 second "movie/commercial" that will be put on youtube. I've used Motion 4 to create using just text and jpg pictures. I've imported these various scenes into Final Cut Pro and have added transitions and edited. When I'm not playing the movie from the timeline, the text and pictures are crystal clear. After rendering, when I play the timeline, all the pictures and text are fuzzy. I thought that once I exported the video, it would look clear...but it doesn't. Can somebody give me some direction on what I need to do so that everything looks clear? It doesn't have to be HD quality...just clear. I don't have a lot of experience with Final Cut as I have been using Adobe Premiere Elements for the last 5 years. Its getting very frustrating.
Thanks
Greg

The white background you are selecting is only a tool to help view the image in the canvas. It does not actually place a background in your sequence. To have a white background, click on the Generator Button ( lower right corner of the Viewer window with an "A" on it) and from the drop down menu, choose Matte > Color. This will load a solid color into the viewer. Click on the Controls tab in the viewer and adjust it to the color you want - in this case white.
Next, on your sequence, if you don't already have an available Video track above your edited clips, then add one by control-clicking on the space above V1 and select Add Track:
This will add another track:
Select your video clips on V1, and move them directly up to V2 by selecting them, then clicking down and dragging the selected clips up to V2 so that V1 becomes empty:
And then edit the color you have in the viewer to V1:
Now you will have a White background behind what ever is on the higher Video Tracks. If you have a long edit, you may need to edit the white color a couple times to make it run the length of the edit.

Help with a simple program please

Hello, I am trying to create a java program that will request a password from the user (just input no gui fancy stuff) and give the user 5 tries to get it right. After the 4th guess, it needs to go from "You have # trials left." to "You have 1 trial left." It needs to become singular.
I have successfully created a program that does this, but it uses 5 if statements and 1 while. I was curious as to if there was a way to make this more "pretty" to look at. Perhaps eliminate some of the ifs. I'm not sure, but some help would be great. Thanks!

Sorry, this is lessakilla. It seems I have two accounts here. I'll look into fixing that. But here is my dilemma still.
Well, I'm looking for a cleaner look. My program works fine and does what I want it to do, but i was wondering if I could somehow eliminate some of the if statements. There is a skeleton of the program below. Thanks in advance!
while count < 3
 if guess.equals(password)
print (correct. welcome)
 print (incorrect, you have (4 - count) trials left.)
++count;
 }Then I have this
if count == 3
 if guess.equals(password)
print (correct. welcome)
print (incorrect, you have (4 - count) trial left.)
++count;
 }Finally I have this
if count == 4
 if guess.equals(password)
print (correct. welcome)
print (incorrect, you lose.)

Can you please help me with this simple (not for me:) issue

Why this doesnt work?
public void spl ()
String a=("moon.sun");
String [] f=a.split(".");
System.out.println(f[0]);
}

The second expression to split() is a regular expression. A period in a regular expression matches all characters, and you're wanting it to just match a period.
To match just the period for your split, you'll need to escape it:String[] f = a.split("\\.");

Can anyone help me with a simple java programm in linux?

i just started learning how to write java code in high school and we had an assignment which required us to write a program that would calculate the amount of kilometers u traveled into miles and vis-versa but we had to give the user a chance to pick which one they had to do and our teacher told us to give them the option using 1 to calculate from kilometers to miles and 2 to calculate miles to kilometers .....
and i got confused so please help

First figure out an algorithm: how would you solve this problem just using pencil and paper. Once you know your equations and steps to take, then translate to Java. Why not give it a try first? You can't break your computer by doing this. Then come back with your code if you are still stuck.
Good luck.galaxyboy25,
This is very good advice. Getting into the habit of working out problems on paper/whiteboard first will save you many a headache later on. I'm relatively new to programming as well (only about 2 years professional experience) but this technique has helped me immensely in my work. In my mind, writing code is easy--figuring out what to write is where the real challenge is.
One other thing. In addition to sketching your problem on paper, it always helps to break a problem into very small, simple, and easily solvable pieces. Then put them together. In doing this you will find that not only will this make your task of problem solving much easier but you also end up writing cleaner and more flexible code.

Help to solve this simple problem- please

Hi !
Is there any method to resolve this problem.
In my db there are 2 tables called Employee and Insurance. There fields as follows.
Employee(empno,name,age,address,phone)
Insurance(empno,insurName,insurCompany)
Now I want to do this.In my HTML form,there are textboxes to input all of these data.
Eg: empno,name,age,address,phone,insurName,insurCompany (All of these enter into 1 form)
Now my problem is, how to save these data into the 2 seperate tables by using PreparedStatement.See am I right?
INSERT INTO Employee,Insurance VALUES (?,?,?,?,?,?,?);
Is it right? I'am confusing about these para's, because how can I tell to insert that first para (empno) into 2 tables.
I using Java2 SDK,JSP,TOMCAT with MySQL db for this.
Please anyone can answer this, help me.

No, you need one INSERT statement for each table.

Could anyone help me with Adobe Application Manager please? I write my approved serial number but can´t go further?

I bought a Student version CS5 back in 2010 for my studies and it worked wonderfully until last week. Now when I try to open any of the Adobe programs, it takes me to Adobe Application Manager and asks for me to provide my serial number. When I write it, it´s approved but it still does not allow me to open any of the Adobe programs. Instead, it asks me again for the serial number. I called support and they confirmed my serial number is correct but they do not deal with CS5 over the phone anymore. Could anyone kindly help me through here please? Many thanks in advance.

When I try to open any Adobe program, "Adobe Creative Suite 5 Design Standard - Adobe Software License Agreement" pops up. I press "Agree" and then it takes me to the next part: "Provide A Serial Number" because my trial had expired. I had never agreed to a trial back when I bought the CS5 package because I had the package, of course. And I have never had any troubles/messages to access my Adobe programs until last week. I called Adobe to confirm my serial number and it is correct but then the person could not help me further because they do not deal with CS5 over the phone, hence asking through here. Once I write the serial number, I get a green tick saying that "This serial number will be used for: Adobe Creative Suite 5 Design Standard". I then press "Complete" and it takes me all the way back to the "Adobe Software License Agreement". It has been this vicious circle over and over. I unistalled it, then installed it again various times using my serial number and ID, I don´t know what else to do and everyone I call they can not help me for some reason. So thank you very much for taking your time in helping me out.

Iphoto has stopped working.Help me with any possible ideas please..

I have a 9.1.3 version of iphoto'11 on macbook pro with Mac OS X 10.6.6. I can get the application to open but it does not upload and keeps showing the circular 'in process' sign on the iphoto page continuously. Please

You might consider updating the app and your OS. The latest version of 10.6 is 10.6.8 and the latest version of iPhoto that will run on that is 9.2.3
Other than that:
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

TD
