How to import a class that is in the database?

Here's the picture: I have a server running on a machine and the client side is a stored procedure located in the database. Instead of writing multiple parameters on the stream, I send a Map of parameters. Therefore, both sides of the server needs to "know" the keys of my parameters in the Map. So I end up declaring constants in both the client and server class.
Is there a way for the server to import the static content of the client class that's in the database? ( Or vice-versa )
Thanks in advance!

Is this a JDBC question?
Meta data solutions mean that you will only find problems at runtime that would be obvious at compile time with a non-metadata solution. Code generation makes production of large numbers of these easy.
But if you want metadata then you create a seperate class in a seperate package which holds the constants. The specifics depend on the implementation but you will typically have one class for each 'type' that is supported.
That package is used by both the server and the client code.
You can of course put other common functionality in the package (like a wrappers for the collections themselves, validation of names, etc.)

How to import a class that have no package

I have .class archive that i need to use in a web aplication on Tomcat. I put the class in the directory: <webapp>/WEB-INF/classes/.
The class doesn�t have a package, so when i tried to import (..page Import=".....") it, tomcat gave me an error because is looking for a package instead of the class.
then i try to use it without the import and tomcat gave another error because it can�t find the class.
Any ideas??
by the way.. I don�t have the source code, I just have the .class archive..
thank you....

Also, I already found that the class had no package. Then you are out of luck.
As of java 1.4 you can no longer import classes that are not in a package. [url http://bugs.sun.com/bugdatabase/view_bug.do;jsessionid=c85f07c1ce8f344d787b7a5146d68:WuuT?bug_id=4361575 ] Full details here
The only solutions I can think of
1 - get the people who originally gave you the class to package it properly.
2 - Decompile it to java code, Change the java code to put it in a package and recompile it. Depending on the complexity of the class this may or may not be a trivial operation.
Good luck,

How To display a table that resides in the database via JFrame.

Hi,
I need to display the contents that present in the table that resides in my database.
Scenario:
Im having Main frame window, in that im having a button, while clicking that button a new JFrame should be opened & it should display all the rows & cols of dat table that resides in my DB.
I have no prob in opening a new JFrame during a button click, but i dont knw how to display table in the table format.
I tried JTable but i dont know how to pass the data into the JTable.
Kindly help me out!!!

JTable relies on a TableModel to deliver data. You have several ways of providing this data:
- Read it into either a Vector of Vectors (list of rows containing list of columns) or an Object[][] and create the JTable while passing the data.
- Create a javax.swing.table.DefaultTableModel, pass it to the JTable as a model, configure it and call addRow() in order to add rows.
- Create a custom table model class; see javax.swing.table.AbstractTableModel for a convenient base class

How to import other class in Flex Builder2?

I use Flex Builder2,I want to import the other class,such as
ascb,like follows:
package {
import flash.display.Sprite;
import ascb.units.Converter;
import ascb.units.Unit;
import flash.events.Event;
public class ApplicationExample extends Sprite {
private var _square:Sprite;
private var _angle:uint;
public function ApplicationExample() {
_square=new Sprite();
_square.graphics.lineStyle(0);
_square.graphics.drawCircle(0,0,2);
addChild(_square);
_angle=0;
addEventListener(Event.ENTER_FRAME,move);
private function move(event:Event):void{
var
converter:Converter=Unit.DEGREE.getConverterTo(Unit.DADIAN);
var angleRadians:Number=converter.convert(_angle);
_square.x=Math.cos(angleRadians)*100+200;
_square.y=Math.sin(angleRadians)*100+200;
_angle++;
ApplicationExample.as is locate in direcotry C:\workspace,and
I put package ascb into directory C:\workspace too,then I run
ApplicationExample.as ,it raise following error:
Description:A file found in a source-path must have an
externally visible definition. If a definition in the file is meant
to be externally visible, please put the definition in a package.
Resource:Converter.as
In Folder:ApplicationExample/ascb/units
Location:line -1
By the way,when I write import ascb.,it should show units,but
it only show util, I guess I may put package ascb into wrong
director,or the ascb don't put the route of Flex Builder2. I don't
know how to do it!
Please give me detail steps to solve above error!
Thanks in advance!

when I put as
import a;
while compiling, it prompt : '.' expected
how to resolve it?
thanksIn J2SDK 1.4, you can only import a class that is in a named package. The compiler is expecting a package_name.class_name;
You do not need to import classes that are in the same package and all classes that do not specify a package name are in the same unnamed package. However you must import classes that are in different packages.

How do I import a file that is on the desktop to iMovie?

How do I import a file that is on the desktop to iMovie?
I had some 8 mm film put onto DVD by yesdvd and now want to import the 3 hours of video into iMovie to edit and create a short story.
I have created a dmg file on my desktop from the DVD but am at a loss as to what's next. There are a bunch of files on the dmg file, including one that says video, which has a bunch of files in it that are video. I assume I need to convert them to a format which iMovie likes. Which one should I use, and which program should I get to do it?
Once I have done that, where should I put the converted files and how do I work with them using iMovie?

You need to convert the VOB files in the TS-Folder of the DVD back to DV which iMovie is designed to handle. For that you need mpegStreamclip:
http://www.squared5.com/svideo/mpeg-streamclip-mac.html
which is free, but you must also have the Apple mpeg2 plugin :
http://www.apple.com/quicktime/mpeg2/
(unless you are running Lion in which case see below))
which is a mere $20.
Another possibility is to use DVDxDV:
http://www.dvdxdv.com/NewFolderLookSite/Products/DVDxDV.overview.htm
which costs $25.
For the benefit of others who may read this thread:
Obviously the foregoing only applies to DVDs you have made yourself, or other home-made DVDs that have been given to you. It will NOT work on copy-protected commercial DVDs, which in any case would be illegal.
And from the TOU of these forums:
Keep within the Law
No material may be submitted that is intended to promote or commit an illegal act.
Do not submit software or descriptions of processes that break or otherwise ‘work around’ digital rights management software or hardware. This includes conversations about ‘ripping’ DVDs or working around FairPlay software used on the iTunes Store.
If you are running Lion:
From the MPEG Streamclip homepage
The installer of the MPEG-2 Playback Component may refuse to install the component in Lion. Apple states the component is unnecessary in Lion, however MPEG Streamclip still needs it.
To install the component in Lion, please download MPEG Streamclip 1.9.3b7 beta above; inside the disk image you will find the Utility MPEG2 Component Lion: use it to install the MPEG-2 Playback Component in Lion. The original installer's disk image (QuickTimeMPEG2.dmg) is required.
The current versions of MPEG Streamclip cannot take advantage of the built-in MPEG-2 functionality of Lion. For MPEG-2 files you still need to install the QuickTime MPEG-2 Playback Component, which is not preinstalled in Lion. You don't have to install QuickTime 7.

How to call a class that extends a frame from a panel ?

How to call a class that extends a frame from a panel ?
I am trying to create an application say "Videoshow"
Videoshow has a panel which in turn consists of 2 components : 1]a textarea( to show the contents of a page) and 2] a mediaclip(to show the video).
Now I have an application "MediaApplication"(to show the videoclip) which extends Frame (Code from Java 2 Unleashed, Chap 21). I want to show this MediaApplication in Component 2 of the above panel. But when I do this, I only see the MediaApplication frame instead of the whole SlideShow.
I want to do something likethis.
VideoShow :
|---------------------------------|-------------------|
| |
| (Comp 1) | (Comp 2)
| TEXTAREA | Video Clip
| |(MediaApp entends Frame)
|---------------------------------|-------------------|
What is the best way to achieve this ? Also which component can I use to show the videoclip ?

im not familiar with the code you mention from Java 2 Unleashed, but your best bet is to read up on Swing a bit - so you get an idea of how Swing containers and components work - then im sure you'll find a solution to your problems. Then if you encounter any difficulties whilst your attempting to do that, post your code in the Swing forum and im sure someone will help you.

Great exercise to document the problem like this. It got me thinking about how an app with modules would be different from an app that does not use modules. Solution: I moved the dummy reference of PersonPhotoView out to the main application file (as opposed to being inside the module) and it worked. I've probably been lucky not to have experienced this problem earlier, because for most other entities I have an instance attached to my model which is linked / compiled with the main application.

IPhone question: Im trying to update applications on my iphone. When I do it I'm as for password from a different Apple ID from what I have in Itunes. How do I change so that both are the same?

All apps are tied to the apple id that it was used to purchase or download the app.
did you use a different id to buy the app?
you can change id, settings - appstore - apple id - log out and log in with correct id.

Thank you.

Should be able to do so from the Users pane (select the user then click the "-" below the list of users. That worked for me with all but one out of five users I deleted. No matter what, their Wiki person page remained, so I hid it from view.
