Facing problem in Java Swing
Hi Sir,
I am using a java GUI Object for taking user name and password (in fields of user name and password) and would like to send the information to a server (in the form of Xml file) on the click of 'Ok' button. The database of registered user is stored on server. If the entered users name or passwords are not correct, the server will send a failure notification to the client (terminal where we typed user name and password). If this is successful, it gives a success notification.
I am doing this using Swings. Also I want all the communication taking place between the server and the client in the form of XML files. being a new to Swings I am facing certain difficulty.
I will appreciate your suggestions and help in this regard.
Thanks and regards,
Sarib

Could you please tell me under which category I should post this query. I could not find JAVA Swing section anywhetre in forum home.Steps
1. Determine what it is that you want the database to do and what you want your code to do. This does NOT involve writing code.
2. Learn JDBC
3. Write JDBC classes that does ONLY the database functionality from 1. If it has GUI (swing) code then it is wrong.
4. Unit test it.
5. Learn Swing
6. Write GUI (swing) code that uses the code from 3.
7. Test it.
There is a forum for JDBC - steps 2,3,4.
There is a forum for Swing - steps 5, 6, 7.

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.

Problem in java swing programming
Hello
I am developing one project. I which i put one main menu from which user choose various options.
One of the option is associating students with the batch.
As user choose this option, it opens one frame in which user get one comobox containing list of batches that are already announced in the system.
As user choose any of these batch number, i want that frame shows the one JLabel control and one JList control shows list of candidates registered for the course for which selected batch has announced.
For that i put one penal in the frame which implements ActionListener interface and registered this panel as the ActionListener of this batch combobox. As user choose any of the batch from this combobox in the actionPerformed method i call repaint method.
In the paintComponent method of panel i add two control one JLabel and one JList .
But my panel or frame does not show these control.
What should i do.
I also want to know i develop projects in JDK1.2 will it runs on JDK1.3 or JDK1.4
Because i was using JDK1.2 but it had deleted and i now i am unable to get that version.Here is some good advice. Take time to download a new version of the SDK, it will help you do things more quickly.
To your problem, I believe it is a matter of switching components within the application. To switch components, you need to use the container.remove(Component c) method, and then use container.add(Component c)Finally you need to validate the container and repaint it to show your newly added component. So in all
container.remove(somecomponent);
container.add(anothercomponent);
container.validate();
container.repaint();Hope this helps one way or the other

Please helpCheck this out :
btnClose.addActionListener(new ActionListener(){

Problem with Java after Software Update to 10.5.7
Hi,
I am facing problem with Java after having run Software upgrades.
Here is the whole story. I recently moved to iMac 10.5.6 from PowerPc 10.4. On this new machine I was having problem running a 3rd party application, which requires JVM. As this application worked well on Tiger, I decided to upgrade JVM on my iMAC using Software Upgrade(was I insane!!). As I like my systems to be updated (as with linux on my personal machine) I clicked "install all". As a result I have the following upgrades run on my machine:
2009-05-20 13:12:01 +0200: Installed "Mac OS X Update Combined" (10.5.7)
2009-05-20 13:12:10 +0200: Installed "Remote Desktop Client Update" (3.2.2)

2009-05-20 13:59:58 +0200: Installed "iTunes" (8.1.1)
But now, simply running $java on the prompt hangs, i.e. it takes no action.

cheersHi man,
In the wake of this java problem I resorted to keep working on my old machine, and today in my spare time I tried to fix this new machine.
So I execute $java on prompt, and then try to check the files it has opened, using lsof -p pid
I see it referring to
/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin/java
isn't this usually the JAVA_HOME
However, executing $/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home/bin/java
hangs!!
but
$/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java
works!!
$ pwd
/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home/bin
$ ./java -version

Linking my Current and CurrentJDK to 1.6 and it works!
However, shall that be the reason!
what is in your /Versions/Current/
I got the following
$ ls /System/Library/Frameworks/JavaVM.framework/Versions/Current

There is no /Home in here, which is usually the case for /1.5 or /1.6
Anyways, things seems to work for the moment. Lets see if I get problem with using Java.

Facing Problem in Deploying EAR for Client Java Proxy.
Hi All,
I am facing problems in deploying EAR in PI/XI server.
The scenario is Client Java Proxy to SAP
. I have followed the the pdf-how to create java proxies in 3.0. Using that I have created the EJB module and it archive.
Finally created the EAR without errors. But while deploying the same in PI server, it throws the following error. Please do help me out in providing any inputs on the same.
Deploy trace is seen below:-

DhanaHi,
Thanks for your input..
I have also opend the EAR as ZIP file and deleted the existing listing libaries
apart from the actual implementing Jar and META-INF folder.
I have tried deploying the Jar for the second time, it is throwing the same error.
What I did is...Once the EAR is created, I went to Resource perspective in NWDS and copied the EAR from the EAR project and used the same for deployment.
Is there is anything else to be modified or deleted before deployement?

Chess: Java Swing problem!! Help need
Hi, I have just learn java swing and now creating a chess game. I have sucessfully create a board and able to display chess pieces on the board. By using JLayeredPane, I am able to use drag and drop for the piece. However, there is a problem which is that I can drop the chess piece off the board and the piece would disappear. I have try to solve this problem by trying to find the location that the chess piece is on, store it somewhere and check if the chess piece have been drop off bound. However, I could not manage to solve it. Also, I am very confuse with all these layer thing.
Any suggestion would be very helpful. Thanks in advanceI wonder if you are biting off a little more than you can chew. This seems like a big project for a beginning coder. Anyway, my suggestions can only be general since we only have general information:
1) Break the big problem down into little pieces. Get the pieces working, then put them together.
2) Make sure your program logic is separate from your GUI.
3) If still having problems, post an SSCCE. See this link to tell you how:
http://homepage1.nifty.com/algafield/sscce.html
4) And as camikr would say (and flounder just said): next time, post this in the Swing forum.
Good luck! -
UI problem when run java swing application on MAC OSX
Hello,
I have problem when i run my java swing application on MAC OSX.
Dialog box is not properly visible in MAC means ita size increses.
its size incresed and and some content or buttons on that dialog are not fully visible.
I can only see partial message or button.
If any one have idea about this problem then give the solution.
Thanks :)
ShwetaI am using following way to create dialog
JOptionPane optionpane = new JOptionPane(new Object[]{lblMsgUp}, JOptionPane.OK_CANCEL_OPTION, JOptionPane.INFORMATION_MESSAGE, null, choices, "Save");
JDialog dialog = optionpane.createDialog(parent, "Save");
dialog.setSize(450, 125);
dialog.setVisible(true); -
Problem in printing a java swing form
Hi,
Could anyone help me on how to set the page margings while I print a java swing form since it is taking a lot of space as margins in the top right top and bottom how do i do that. or is it that java can only print in the printable area or is there any way i can increase the scope of the printable areaI used PrintRequestAttributeSet and set the margins to 0.5 on all four sides by creating an instance of MediaPrintableArea. By default, the margins on all sides comes up as 1.0 inch. Default paper size is LETTER (8.5 x 11).
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(new MediaPrintableArea(0.5f,0.5f,7.5f,10.0f,MediaPrintableArea.INCH);
PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.setPrintable(component);
if(printJob.printDialog(aset))
printJob.print(aset);
hope it helps. -

Thanks,its working now. Actually i was trying example from the below link...
http://java.sun.com/products/jfc/tsc/articles/treetable1/
which suggested to download Swing 1.1 Beta 2.
I am using J2sdk 1.4 version.
For compilation i had to change some of imports
for example
//import com.sun.java.swing.tree.*;

Facing problem while going to catch return result from web-services.
Hi everybody,
I am new to BPEL. I am facing problem while going to catch the attributes of resultsets returning from web-services(QAS). As far as my knowledge, two types of results it should return - XML entities and another is attributes which is coming as the part of XML entitites. I am able to catch the XML entities, but can't catch the attributes under it. Even, I am not able to see whether web-services returning something within that field.
When, I tried to catch the attribute and store to a temporary varilable using the following code:
*<assign name="AssignQASDoGetAddress1">*
*<copy>*
*<from variable="InvokeQAS_DoSearch_OutputVariable"*
part="body"
query="/ns6:QASearchResult/ns6:QAPicklist/ns6:PicklistEntry/@PostcodeRecoded"/>
*<to variable="temp"/>*
*</copy>*
*</assign>*
but, I am facing the following selectionFailure errors after running it:
*"{http://schemasxmlsoap.org/ws/2003/03/business-process/}selectionFailure" has been thrown.*
-<selectionFailure xmlns="http://schemasxmlsoap.org/ws/2003/03/business-process/">
-<part name="summary">
*<summary>*
empty variable/expression result.
xpath variable/expression expression "bpws:getVariableData('InvokeQAS_DoSearch_OutputVariable', 'body', '/ns6:QASearchResult/ns6:QAPicklist/ns6:PicklistEntry/@PostcodeRecoded')" is empty at line 269, when attempting reading/copying it.
Please make sure the variable/expression result "bpws:getVariableData('InvokeQAS_DoSearch_OutputVariable', 'body', '/ns6:QASearchResult/ns6:QAPicklist/ns6:PicklistEntry/@PostcodeRecoded')"is not empty.
*</summary>*
*</part>*
*</selectionFailure>*
Getting this error it seems to me that web-service is returning nothing, but, it returns something as it has been catched using a method called isPostcodeRecoded() Java Code in Oracle ADF. This method has been used as it should return boolean whereas for catching the xml entities using java code we used the method like getPostcode(), getMoniker().
For your information, we are using Jdeveloper as the development tool for building the BPEL process.
Am I doing any syntax error. Please consider it as urgent and provide me asolution.
Thanks in advance.
Chandrachur.Thanks Dave and Marc, for your suggestions. Actually what I found is QAS web-service is returning nothing as attributes when the attributes are set to the default value. For example, following is the part of the wsdl of the result which QAS webservice returns.
<xs:element name="QASearchResult">
- <xs:complexType>

<xs:attribute name="IncompleteAddr" type="xs:boolean" default="false" />
<xs:attribute name="UnresolvableRange" type="xs:boolean" default="false" />
<xs:attribute name="PhantomPrimaryPoint" type="xs:boolean" default="false" />
</xs:complexType>
here the attributes like FullAddress, PostcodeRecodedare , etc. are not being return by the web-service when it is getting the default value false. But, if it gets true then , it is being displayed at the BPEL console.
Do you have any idea how can I catch the attributes and its value even when it gets the default value which is already set. Previously, it was returning(it was not being displayed at the console).
Thanks once again for your valuable suggestions...!!!

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.

I would like to build 'ZOPE' inside Oracle DB as a back-end
Using Flash MX as front-end.
