JFC/Swing and java Swing
Are JFC Swing and java Swing both different?
Thanks.
Nope. Swing is Swing.

What is difference between C# Gzip and Java swing GZIPOutputStream?
Hi All,
I have a Java swing tool where i can compress file inputs and we have C# tool.
I am using GZIPOutputStream to compress the stream .
I found the difference between C# and Java Gzip compression while a compressing a file (temp.gif ) -
After Compression of temp.gif file in C# - compressed file size increased
while in java i found a 2% percentage of compression of data.
Could you please tell me , can i achieve same output in Java as compared to C# using GZIPOutputStream ?
Thank a lot in advance.797957 wrote:
Does java provides a better compression than C#?no idea, i don't do c# programming. and, your question is most likely really: "does java default to a higher compression level than c#".
Btw what is faster compression vs. better compression?meaning, does the code spend more time/effort trying to compress the data (slower but better compression) or less time/effort trying to compress the data (faster but worse compression). most compression algorithms allow you to control this tradeoff depending on whether you care more about cpu time or disk/memory space. -
PL/SQL and Java Swing interface
Everybody in this forum knows that Oracle is the best database around
with many functionalities, stability, performance, etc. We also know
that PL/SQL is a great language to manipulate information directly
in the database with many built in functions, OOP capability,
transaction control, among other features. Today an application that
manipulates information, which needs user interface, requires components
to be developed using different technologies and normally running in
different servers or machines. For example, the interface is done using
a dynamic HTML generator like JSP, PHP, PL/SQL Web Toolkit, etc.
This page is executed in an application server like Oracle iAS or
Tomcat, just to name two, which in turn access a database like Oracle to
build the HTML. Also rich clients like Java applets require an intermediate
server to access the database (through servlets for example) although
it is possible to access the database directly but with security issues.
Another problem with this is that complexity increases a lot, many
technologies, skills and places to maintain code which leads to a greater
failure probability. Also, an application is constantly evolving, new
calculations are added, new tables, changed columns. If you have an
application with product code for example and you need to increase its
size, you need to change it in the database, search for all occurrences
of it in the middle-tier code and perhaps adjust interfaces. Normally
there is no direct dependency among the tier components. On another
issue, many application interfaces today are based on HTML which doesn't
have interactive capabilities like rich-client interfaces. Although it
is possible to simulate many GUI widgets with JavaScript and DHTML, it is
far from the interactive level we can accomplish in rich clients like
Java Swing, Flash MX, Win32, etc. HTML is also a "tag-based" language
originally created to publish documents so even small pages require
many bytes to be transmitted, far beyond of what we see on the screen.
Even in fast networks you have a delay time to wait the page to be
loaded. Another issue, the database is in general the central location
for all kinds of data. Most applications relies on it for security,
transaction and availability. My proposal is to use Oracle as the
central location for interface, processing and data. With this approach
we can create not only the data manipulation procedures in the database,
but procedures that also control and manage user interfaces. Having
a Oracle database as the central location for all components has many
advantages:
- Unique point of maintenance, backup and restore
- Integrated database security
- One language for everything, PL/SQL or Java (even both if desired)
- Inherited database cache, transaction and processing optimizations
- Direct access to the database dictionary
- Application runs on Oracle which has support for many platforms.
- Transparent use of parallel processing, clusters and future
background technologies
Regarding the interface, I already created a Java applet renderer
which receives instructions from the database on how to create GUI
objects and how to respond to events. The applet is only 8kb and can
render any Swing or AWT object/event. The communication is done
through HTTP or HTTPS using Oracles's MOD_PLSQL included in the Apache
HTTP server which comes with the database or application server (iAS).
I am also creating a database framework and APIs in PL/SQL to
create and manipulate the client interface. The applet startup is
very fast because it is very small, you don't need to download large
classes with the client interface. Execution is done "on-demand"
according to instructions received from the database. The instructions
are very optimized in terms of network bandwidth and based on preliminary
tests it can be up to 1/10 of a similar HTML screen. Less network usage
means faster response and means that even low speed connections will
have a good performance (a future development can be to use this in
wireless devices like PDAs e even cell phones, just an idea for now).
The applet can also be executed standalone by using Java Web Start.
With this approach no business code, except the interface, is executed
on the client. This means that alterations in the application are
dynamically reflected in the client, no need to "re-download" the
application. Events are transmitted when required only so network
usage is minimized. It is also possible to establish triggering
events to further reduce network usage. Since the protocol used is
HTTP (which is stateless), the database framework I am creating will
be responsible to maintain the state of connections, variables, locks
and session information, so the developer don't need to worry about it.
The framework will have many layers, from communication up to
application so there will be pre-built functions to handle queries,
pagination, lock, mail, log, etc. The final objective is to have a
rich client application integrated into the database with minimum
programming and maintenance requirements, not forgetting customization
capabilities. Below is a very small example of what can de done. A
desktop with two windows, each window with two fields, a button with an
image to switch the values, and events to convert the typed text when
leaving the field or double-clicking it. The "leave" event also has an
optimization to only be triggered when the text changes. I am still
developing the framework and adjusting the renderer but I think that all
technical barriers were transposed by now. The framework is still in
the early stages, my guess is that only 5% is done so far. As a future
development even an IDE can be created so we have a graphical environment
do develop applications. I am willing to share this with the PL/SQL
community and listen to ideas and comments.
Example:
create or replace procedure demo1 (
jre_version in varchar2 := '1.4.2_01',
debug_info in varchar2 := 'false',
compress_buffer in varchar2 := 'false',

end;Is it sound like Oracle Portal?
But you want to save a layer 9iAS.
Basically, that was the WebDB.(Oracle changed the name to Portal when version 3.0)
Over all, I agree with you.

You find examples and code by searching the internet, not by using forums.
Start with The Java Tutorials - it has trails for the bulk of the Java functionality.
See the trail 'How to Write an Undoable Edit Listener'
http://docs.oracle.com/javase/tutorial/uiswing/events/undoableeditlistener.html
You learn by DOING - not by reading. Actually DO the tutorial example and try to understand WHAT it does and HOW it does it.
Then search for other tutorial trails that are of interest. -

Was just wundering if it is possible to query a java jdo database with a swing frontend, and if so if anybody can direct me to any helpful websites.
CheersSure it is possible.
Do you know JDO? Googling for "JDO tutorial" should get you well on your way. Ditto for Swing / Swing tutorial.
Keep the database stuff and the GUI stuff in separate classes. That way you can write quickie command line main() functions to test a database method. Or, as you advance, you may want to learn about jUnit (->google).
There are application architecture issues that are mucho difficult to guess at without more details. Such as if your application is pretty big, you might want to look into some sort of client/server distributed architecture. But for simpler stuff, a single application should be a fine way to start. -
System IP address and Java+Swings
Hi!
I m designing a Network Application in Java. While desiging Front End using swings, i want if the System IP is changed the application should know that. I m sure my code is logically correct and calls
try {
this.systemIP = null;
this.systemIP = InetAddress.getLocalHost().getHostAddress();
catch (Exception ex)
System.out.println (ex.getMessage());
}but its the fault of JVM, i think, it keeps Local System IP unchanged until the application is closed and reload..
What should i do in this scenario...plz guide me!
Regards>
but its the fault of JVM, i think, it keeps Local
System IP unchanged until the application is closed
and reload..
That would be my guess.
What should i do in this scenario...plz guide me!You already answered the question. You restart the application.
You could probably do something using JNI, but whether that works depends on what you are doing with the IP in your java code (although there are some obscure command line options/properties that might make it work.) -
AWT vs SWING vs JAVA 2D vs JFC
Hi,
can you please describe or show me the path to find the difference
among 4. (mentioned in subject line)
The basic difference i know, what i want is how to decide when to use
what?
In my view, awt is used no where these days.
swing and Java 2D (what is this?) are used mostly but which to choose
for my application, how to decide? and What is JFC all about?
sometimes it becomes very confusing.
Can anyone throw some light on these terms.

Problem with java swing button and loop
Problem with java swing button and loop
I�m using VAJ 4.0. and I�m doing normal GUI application. I have next problem.
I have in the same class two jswing buttons named start (ivjGStart) and stop (ivjGStop) and private static int field named Status where initial value is 0. This buttons should work something like this:
When I click on start button it must do next:
Start button must set disenabled and Stop button must set enabled and selected. Field status is set to 1, because this is a condition in next procedure in some loop. And then procedure named IzvajajNeprekinjeno() is invoked.
And when I click on stop button it must do next:
Start button must set enabled and selected and Stop button must set disenabled.
Field status is set to 0.
This works everything fine without loop �do .. while� inside the procedure IzvajajNeprekinjeno(). But when used this loop the start button all the time stay (like) pressed. And this means that a can�t stop my loop.
There is java code, so you can get better picture:
/** start button */
public void gStart_ActionEvents() {
try {
ivjGStart.setEnabled(false);
ivjGStop.setEnabled(true);
ivjGStop.setSelected(true);
getJTextPane1().setText("Program is running ...");
Status = 1;
} catch (Exception e) {}
/** stop button */
public void gStop_ActionEvents() {
try {
ivjGStart.setEnabled(true);
ivjGStart.setSelected(true);
ivjGStop.setEnabled(false);
getJTextPane1().setText("Program is NOT running ...");
Status = 0;
} catch (Exception e) {
/** procedure IzvajajNeprekinjeno() */
public void IzvajajNeprekinjeno() { //RunLoop
try {
int zamik = 2000; //delay
do {
Thread.sleep(zamik);
PreberiDat(); //procedure
} while (Status == 1);
} catch (Exception e) {
So, I'm asking what I have to do, that start button will not all the time stay pressed? Or some other aspect of solving this problem.
Any help will be appreciated.
Best regards,
TomiThis is a multi thread problem. When you start the gui, it is running in one thread. Lets call that GUI_Thread so we know what we are talking about.
Since java is task-based this will happen if you do like this:
1. Button "Start" is pressed. Thread running: GUI_Thread
2. Event gStart_ActionEvents() called. Thread running: GUI_Thread
3. Method IzvajajNeprekinjeno() called. Thread running: GUI_Thread
4. Sleep in method IzvajajNeprekinjeno() on thread GUI_Thread
5. Call PreberiDat(). Thread running: GUI_Thread
6. Check status. If == 1, go tho 4. Thread running: GUI_Thread.
Since the method IzvajajNeprekinjeno() (what does that mean?) and the GUI is running in the same thread and the event that the Start button has thrown isn't done yet, the program will go on in the IzvajajNeprekinjeno() method forever and never let you press the Stop-button.
What you have to do is do put either the GUI in a thread of its own or start a new thread that will do the task of the IzvajajNeprekinjeno() method.

Java Swing/AWT and FX is so old school! Give me HTML and CSS for GUI!
Dear Java,
I am a seasoned programmer and I feel it's time JAVA implements a GUI system where it uses HTML and CSS for the GUI. For the love of god just look at the interfaces you can make using HTML and CSS alone. I am a big fan of Java Swing and the recent GUI designer for FX is quite cool. But they are just not as simple as HTML and CSS. And JavaFX has some interesting requirements for the graphics.
I know it is possible to use JavaFX and implement the WebView/WebDriver and make it load a HTML page, etc... but why go through all the trouble?
Just imagine... if you make Java where it has powerful back-end to do what it does best and the HTML/CSS powered GUI on the front-end. It will make the lives of many developers much much easier.
I am not sure whether a Swing designed GUI will be faster than a HTML designed GUI... but if you look at a traditional browser and how fast it renders HTML/CSS, I am sure if Java had a native Form where it uses HTML and CSS to render the GUI, Java will make the dreams of many programmers a reality.
Make it happen!!!!Check this i solve problem just now using this

Scope and Objectives of making java swing scientific calculator
I am going to write code for java swing scientific calculator..... can any body help me to write scope and objectives of this project.... please please :-(
If this is for school work, then defining the scope is part of the problem. The only advice I will give you is that you only need to implement what the assignment specifies. It is probably intentionally vague so you can bite off way too much and not finish -- failure should teach you something too.
I had just such an assignment in my software engineering class in college -- create a cross compiler from X to Y where X and Y where known instruction sets. That was the entire assignment -- plus the instruction sets for X and Y. My team looked at the allotted time and resources availabe and decided to do a minimal implementation.
We where the only team to complete the assignment and all recieved A's because we accurately implemented the required solution and were able to evaluate the real problem--resource allotment--accurately.
Each other team tried to add "extras" that would "guarantee" them an A grade. In actuallity it was just a lot more work than they could do though and it hurt them in the long run--No matter how good the work was to the point they had at the end of the semester, each student in the other teams only recieved a B or less grade in the class due to failure on that project. Resource allocation and planning--only you can do that for your team/project. -
