- Ultimate enterprise design pattern for 3 tiered appsSo, I feel I am close here is what I have so far.
Goal: Database driven selection of controls on forms
Goal: Business rules only aware of interfaces
Goal: Presentation layer only aware of interfaces
Database Table Person: Name, BirthDate, Gender, CreateDate, CreatedBy
Value Object:
public class Person {
private String name;
private DateTime birthDate;
private int gender;
private DateTime createDate;
private int createdBy;
}
Business Layer Object:
public interface IPersonModel {
public boolean isTeenager();
public boolean isMale();
public boolean isFemale();
}
Presentation layer Multi Column List control
public interface ITableList {
public int rowCount();
public Object getItemAtRow(int row);
public Object getValueAtRowColumn(int row, int column);
}
public interface ITableItem {
public Object getValueAtColumn(int column);
}
The most complex part is storing in a database table which fields on
the value object will be presented in the multi column list control.
It needs to be user friendly and maintainable.
One time I tried having each value object with a switch statement for a
unique number for each field. So the database contents and source code
are kept in synch e.g. 266 in the database means 'Person CreateDate'
and the value object returns that when implementing ITableItem.
It worked but relies on a code generator to make it all work.
This time around I thought I could keep a script in the database so the
user would pick the first column to be person.getCreateDate(), the
second to be person.getName() etc.
Using reflection I could generate on the fly which attribute will be
displayed in which column.
Anyone think of other options?
The other thing I need to change is it seems an unecessary dependency
for the value object to implement ITableItem - there probably needs to
be another class which does it and depending on the database values
pulls the data from the value object.
The same goes for the value object implementing the business rules.
While probably not too bad if it does, perhaps mapping the values to
something that does might work better.
Apart from the value object I am trying to anything else in all the
code knowing about fields which are only used for CRUD e.g. createDate.
CreateDate may never be used for logic - in my app - ever - so why
pass it around as business objects - better to only have things
implementing interfaces where needed.
What do you think so far?

- JButton layout - equal width with no absurd stretchThank you for taking the time to enlighten me. I have been searching
and trying different things but nothing seems to work for me. All I
want to do is have a column of JButtons to the left of a JScrollPane.
I want the buttons to have equal widths (the widest button at its
minimum text-fitting width, all others stretched to an equal width) and
be only as high as they need to be for their text. The scroll pane can
fill the rest of the width (and height for that matter). Something
like this:
+----------------------------------+
| |
| +--------+ +-------------------+ |
| | A | | | |
| +--------+ | | |
| | ABCDEF | | | |
| +--------+ | JScrollPane | |
| | ABCD | | | |
| +--------+ | | |
| | | |
| +-------------------+ |
| |
+----------------------------------+
I tried box layout, but then the buttons are not equal widths. Border
layout makes the buttons equal widths, but stretches them to be as high
as the scroll pane. Grid layout stretches them both vertically and
horizontally. I think I tried gridbag layout and had the same problem
as grid layout. The type of layout I want for the buttons reminds me of
how a table would layout in an HTML document. I want to avoid using
literal size values because of L&F issues on other platforms. Shrinking
the height of the scroll pane is not an option. Does anyone have any
suggestions?

- mouseClicked vs. mousePressed on Apple vs. WindowsI'm writing a Swing component which must function similarly on Apple
and Windows; and am having trouble with which event to fire off of
(this is effectively a toggle button which would ideally just be
interested in mouseClicked). For a variety of other reasons, I don't
want to make my code act on the mousePressed event.
Originally, our QA person asserted that it was busted because she was
clicking (and moving the mouse > 10 pixels) and it wasn't getting
"toggled" (this was on Windows). I won the battle there by saying
"don't move it 10 pixels; that's a drag, not a click". (after
debugging and figuring out that if you moved the mouse more than
approximately that much, the mouseClicked never came in).
However, she now claims that on Apple (OSX) that the button fails to
toggle if you move the mouse even one pixel while pressing the button.
(i.e. if you are not perfectly still while clicking).
Obviously this would be a different story. I don't have immediate
access to an Apple machine, so was wondering if anybody else had seen
this behavior. When I worked on the AWT on OS/2 at IBM, it was fairly
clear that the mouse events were determined based on native operating
system events (i.e. when Windows says it is a click, we'll say it is a
click). Don't know if that's true now or not, since I haven't seen the
code since Java 1.1.8.

- [encoding]Stupid question regarding encodingI have written a java plugin for an application that reads a file to execute
a series of actions ; when I parse my text file I check for the existence
of the following line "#HEADER" ; it works fine on my equipment ; on
Windows somebody working with the text file encoded in utf-8 told me that
there is problem as the line containing "#HEADER" is not found !
Now I am a little bit puzzled about all this :
(a) when you write java code and compile it what happens to the
string "#HEADER" because it will be used in the following test :
if (line.equals("#HEADER") {...}
where line is read from the text file with encoding as is on the machine
where the class is executed ? in other words you are comparing what to
what ?
(b) when with a Java app you read a text file can you get its encoding
format like utf-8 or ANSI or whatever to decide about some actions to be
taken ?
I think the problem could be easily solved by replacing "#HEADER"
by "_HEADER" but I have to go to the bottom of this to understand what is
going on.
Thanks

- Serial Port CommunicationsI have a java application that I wrote that collects data from a
serial port on a laptop from a data collection device. Program works
well.
My bosses would like certain conditions to draw more attention than
just using the laptop's monitor. They would like two lights and a horn
to be controlled as well.
Tackling the serial input device was pretty easy, but I am not sure
where to start with this request.
1) I only have one serial port on the Laptop, but they want to control
4 devices (horn, light 1, light 2, data collection device). So how
do I handle that?
2) Where would I go to buy the other devices and what device would I
have my java program talk to in order to control them?
Thanks,

- Eclipse 3.3 - external tool arguments issue.
I run the WebSphere command line wsadmin java tool as external tool in
Eclipse. It works fine except where an External tool argument has an
"=" sign as in "-javaoption -Dcom.ibm.ws.management.standalone2=xxxx".
Wsadmin picks up the "-Dcom.ibm.ws.management.standalone2" variable
but not the value. Seems that the Eclipse "arguments" dialog
truncates values after the "=" sign. Is there a way around this.
The arguments are listed below.
-user 1234 -password xyz
-lang jacl -host 11.11.11.11. -port 1111
-javaoption -Dcom.ibm.ws.management.standalone2=xxxx
-wsadmin_classpath C:\WASAdminSBV\WSAdmin\WAS5.1\JACL\proclib.jar
-f ${resource_loc}
The problem does not occur when Wsadmin is run from the command line.

- Advanced Tooltips in JavaHi
I want to implement dynamic interactive tooltips in java so that the
user can expand / collapse them. Also, if there are hyperlinks in the
tooltip text, the user should be able to follow up this link. For the
same purpose, I need to be able to catch any events associated with
tooltips.
I tried to search a lot on how to customize the behavior of tooltips in
Java, however couldn't find any useful information. Does anyone know
about how to proceed about this? Any suggestions / pointers would be
greatly appreciated.
Thanks,

- [OT] Project documentationWell, they _are_ all Java projects... but it's OT, I know. I need to get a
handle on project documentation. Can someone toss out some options for
generating documentation? What is (or could be) behind the numbered
chapter/section/subsection format of the various PDF files (specifications
and manuals) that I download?
I have so far adopted the xml and xsl transform found in many Apache and
Jakarta projects, and that has helped tremendously for HTML documentation,
but I need to be able to hand over a document and say 'this is what I'm
building'.
Thanks,

Symbian is by far the dominant mobile OS worldwide and don't see that
changing soon, although tons of linux phone shipments to china, which
has the largest mobile subscriber base in the world holds hope.
As always, Java ME is the application platform for all these devices.

- JSpinner causes trouble to JB 2005 designer...X-No-Archive: yes
Hi.
I try to build a GUI with the JB 2005 designer (JB 2005
Enterprise-Trial/Fondation version).
Basically it works until I want to add a JSpinner component. Then this
error happens: "null processing BeanInfo class
javax.swing.JSpinnerBeanInfo"
The component is not added. So I add it manually. But the rest of the
GUI components (following the JSpinner member variable) is mixed up
then.
Is there a workaround to this? Thanks.

java-programmer, Socket error Windows getInputStream
Hello,
Java version is 1.5.0_09. I am trying to connect from a Windows
machine to another Windows machine using sockets . Getting a socket
error for the following line. and throws EOFException
Socket s = null;
ObjectInputStream sin = null;
ObjectOutputStream sout = null;
s = new Socket( host, port );
sout = new ObjectOutputStream( s.getOutputStream() );
//write data to socket
sout.writeObject( req );
sout.flush();
InputStream is = s.getInputStream() );
sin = new ObjectInputStream( is ); // This line gives error
If I step into ObjectInputStream, I see:
public ObjectInputStream(InputStream in) throws IOException {
verifySubclass();
bin = new BlockDataInputStream(in);
handles = new HandleTable(10);
vlist = new ValidationList();
enableOverride = false;
readStreamHeader(); // This line gives error
bin.setBlockDataMode(true);
}
However, the same code works when I try to connect from Linux(Red Hat
Enterprise Linux WS release 4 (Nahant Update 5)) to Windows. Turned
off Windows firewall but no luck.
On the Windows Server I am trying to connect to a server agent waiting
on port 2002 that helps me connect to Citrix running on that machine.
The agent runs as a Windows service.
What could be wrong here?

So how do I get around this? I was able to connect until day before
and suddenly I started getting this error.

You might want to use a protocol sniffer to see what the other end is
up to.

The other end, or somebody, send a FIN. No sniffing required really.

- Date ArithmeticArg,
So I know I use the Calendar abstract class. And I am betting that I use
the Add method.
Could I see a example of some date arithmetic, e.g. number of days from
today since 01/01/1964.
Must I work out the differences by year, month, day individually, convert to
a common unit of time, add them, then convert to a displayable unit of time?

- System clock monitoringwe have a java applet game that relies on a thread that ticks at 10n
miliseconds. Our problem is that we use the system clock time to see
the interval of ticks, and if a user manipulates the clock setting,
then we get erronous tick times.
Is there a way we can avoid this, or use the hardware clock , or some
solution where the user inteferenece will not disrupt the game ?

- Accessing the name of the CLASS/JAR file invokedHello,
I am trying to pack all my files into a JAR - this includes CLASS
files and other textual files such as help, std configs, etc.
I would like to be able to extract them from the Java app straight out
of the JAR - and for this I need to know what the name of the JAR file
invoked was (it might have been renamed for X reasons)
Is there any sure way to do this? (the alternative is to have an
external file to contain said data, but I want to know if a way to
have everything self-contained exists, first)
Thanks,

- BPEL Products(Business prcess execution Language 4 webservices)Hi,
I had a few questions about BPEL products
1) Can you let me know the BPEL Servers available in the market. Do
these need to be integrated with J2EE appservers or can they run as is
if all I want to do is integrate a few Java applications and
webservices to the flow.
2) How powerful are Weblogic Integration suite and Websphere MQSeries
Integrator for integrating Webservices using BPEL. Also how easy is it
to develop this kind of flow. Collaxa has a more pure BPEL product
that seems easier for the above task.
Thanks in Advance,

- Is Java really faster than Obj-C ? Should Apple dump Obj-C and go with Java?The old notion that Java on desktops is slow might have to go out the
window if more studies show this:
http://homepage.mac.com/spullara/rants/C1464297901/E775622191/index.html
Again, this points out the fact that there will probably be a
renaissance of Java on desktops as it percolates on Linux and Macs and
Windows desktops. We use Mac OS X iMacs at work and Java apps as
MoneyDance (a personal finance software that runs on all 3 desktops,
although it looks sorta crappy in windows) are very good looking and
extremely fast.
Now, if only IBM's open source eclipse made better looking SWT apps on

- grabbing text from non-edit java windowHow do I get the text (in a java program) from a java window that is not an
edit window (ie, cannot hilight the text with a mouse)? ie, is there
something similar to in functionality to Windows API GetWindowText()?

- imcompatible type when converting a List to arrayI have an ArrayList<Guest> which I want to convert to an Array, but I'm
getting:
init:
deps-jar:
Compiling 2 source files to /home/thufir/JavaProject28/build/classes
/home/thufir/bcit-comp2611-project2/src/a00720398/view/Tabs.java:15:
incompatible types
found : java.lang.Object[]
required: a00720398.data.Guest[]
Guest some_guests[] = FileUtil.getGuests().toArray();
1 error
BUILD FAILED (total time: 6 seconds)
If I change it to:
Object some_guests[] = FileUtil.getGuests().toArray();
then it works fine, but that's rather absurd because I know that the type
is Guest so I don't see why it would have to be an array of Object.
Surely I don't have to cast to Guest?
thanks,

In a platform-portable language, this is unbelievable. You've prevented use
of your product on anything but Windows.

? ummm...It seems that you are dangerous...jijiji
Well, well. Movements, like the rotation, are too fast.If I move a
little the mouse, the scene is moved very fast.
I Can I make it slower?

English...^_^ )
