Is Jdeveloper itself based on adf swing or java swing?

Hi Experts,
Is jdeveloper itself developed on java swing or adf swing?
Also, i need to build a jdev plug-in, if i develop this plugin using adf-swing will it work?

extensions can be added to jdev..
if u r on release 2 use
http://docs.oracle.com/cd/E24382_01/doc.1112/e20067/toc.htm
for release 1

Are JFC Swing and java Swing both different?
Thanks.

Nope. Swing is Swing.

Error deploying Jdeveloper 10.1.3 ADF application on oracleAS 10.1.2

Hi,
i have created an application on Jdeveloper 10.1.3 and when i am trying to deploy it on oracleAS 10.1.2 i get the following error:-
java.rmi.RemoteException deploy failed!: ; nested exception is: oracle.oc4j.admin.internal.DeployerException: Unknown assembly root-tag attribute: xmlns:xsi. deploy failed!: ; nested exception is: oracle.oc4j.admin.internal.DeployerException: Unknown assembly root-tag attribute: xmlns:xs
I searched the forum for a similar kind of error. I got the solution for it.
It mentions about jdk and j2ee versions.I changed my project and jdeveloper libraries and jdk's. But still am getting the same error.
I will post this thread in the jdeveloper forum also.
Please could anyone guide me as to how to approach to this particular scenario.
Thanks in advance.

Helllo,
By default in JDeveloper 10.1.3 ADF application will be based on J2EE 1.4 specification version, where OracleAS 10.1.2 is based on J2EE 1.3.
So J2EE is not compatible in this direction.
Can you migrate your application server to 10.1.3?
If not you will need to create your application based on J2EE 1.3 standards.

How to convert oracle form fmb file to java swing file using Jdeveloper

how to convert oracle form fmb file to java swing file using Jdeveloper.Please explain with detailes steps if possible or please give a link where it is available

There is no automatic way to do this in JDeveloper. I know there are some Oracle Partners offering forms to java conversion, I don't know how much of their tools are automated and done with JDeveloper. With JDeveloper+ADF you basically rewriting the Forms application from scratch (and using ADF is helpful during this process).

IPad 2 and application based on adf rich faces components

Hi,
Seems that the web application based on ADF Rich Faces components (jDeveloper 11.1.1.5.0) don’t operate properly under the latest iPad 2( iOs 4.3.2, wb Safari).
To reproduce, we can try to open oracle demo site - http://jdevadf.oracle.com/adf-richclient-demo/faces/index.jspx. A lot of javaScript errors will appear and the page not open.
The first script error is "Result of expression [[objectDOMWindowConstructor]] is not a constructor", we faced with it in relation to mac os..No matter which web browser and iDeveloper version is used. On the previous iPad (iOs 4.2) there was not this problem.
what does it mean? and how can it be fixed?

See Framework Javascript failing on Safari in iOS 4.3.3
There is no 'official' fix for this since this is a webkit bug on the safari included in iOS 4.3. There is a workaround but it requires a backport patch. You can do it yourself though as I detailed in the link I gave you above.

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',

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.

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,
Tomi

This 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.

Loading large files in Java Swing GUI

Hello Everyone!
I am trying to load large files(more then 70 MB of xml text) in a Java Swing GUI. I tried several approaches,
1)Byte based loading whith a loop similar to
pane.setText("");
             InputStream file_reader = new BufferedInputStream(new FileInputStream
                       (file));
             int BUFFER_SIZE = 4096;
             byte[] buffer = new byte[BUFFER_SIZE];
             int bytesRead;
             String line;
             while ((bytesRead = file_reader.read(buffer, 0, BUFFER_SIZE)) != -1)
                  line = new String(buffer, 0, bytesRead);
                  pane.append(line);
             }But this is gives me unacceptable response times for large files and runs out of Java Heap memory.
2) I read in several places that I could load only small chunks of the file at a time and when the user scrolls upwards or downwards the next/previous chunk is loaded , to achieve this I am guessing extensive manipulation for the ScrollBar in the JScrollPane will be needed or adding an external JScrollBar perhaps? Can anyone provide sample code for that approach? (Putting in mind that I am writting code for an editor so I will be needing to interact via clicks and mouse wheel roatation and keyboard buttons and so on...)
If anyone can help me, post sample code or point me to useful links that deal with this issue or with writting code for editors in general I would be very grateful.
Thank you in advance.

Hi,
I'm replying to your question from another thread.
To handle large files I used the new IO libary. I'm trying to remember off the top of my head but the classes involved were the RandomAccessFile, FileChannel and MappedByteBuffer. The MappedByteBuffer was the best way for me to read and write to the file.
When opening the file I had to scan through the contents of the file using a swing worker thread and progress monitor. Whilst doing this I indexed the file into managable chunks. I also created a cache to further optimise file access.
In all it worked really well and I was suprised by the performance of the new IO libraries. I remember loading 1GB files and whilst having to wait a few seconds to perform the indexing you wouldn't know that the data for the JList was being retrieved from a file whilst the application was running.
Good Luck,
Martin.

be a little more clear..i don't think anyone here understand what you're asking for.
here's my take on your question (guess).
Are you asking for dockable Panel and component?
ie)
you have a create JComponent that is added to a JFrame, etc..
When the user move the mouse over the component, and perform a mouse press, you want to allow the user to move the component to another location (the component is dockable??)
There are severals Dockable panel and compoent out there for free..so i suggest that you would use them ; rather than writing your own.

Help! how can I update JDK from 1.3 to 1.4 for Java Swing correctly?

Urgent! currently I meet one trouble for GUI display, which is developed by Java Swing when I update my JDK1.3 to 1.4. I use JRun as web server and all of the GUI Java Swing code developed based on JDK 1.3 and before I update, all of the GUI display is correct and there are no problem, but after I update to JDK 1.4, I always meet this kind of problem "java.lang NoClassDefFoundError" which is displaye on Java Console and "Exception:java.lang.NullPintException" is displayed on GUI. Sometimes, I need to try two times to display GUI(Jave Swing), then it can work. Could you give me a fever and show me how to fix this problems? which kind of change in JDK Java Swing package?
Thank you much.
Steven

I have recompiled app. by JDK1.4 and I also changed classpath but I can not fix the problem. The strange thing is that I can view the The same GUI(Java Swing) which is installed in another computer using the same JRUN too, but in local computer I can not view the GUI. Do you have some other suggestions? Why Can I view the same GUI instaaled in another computer?
Very Thanks
Steven

Java Swings Vs Flex which is better?

Hi,
I do not know whether this is the right place to post this thread. We are planning to replace Java Swings client with Adobe Flex GUI. So I am in the process of analyzing the performances and advantages of Flex over Java Swings.
So, Can any one kindly let me know whether Flex supports all the features of Java Swings (like components... etc).
Actually my backend server is also Java and the communication between client and server is based on CORBA.
So, considering all these constraints please comment on this.
Regards,
Purush.

Both support object-oriented GUI development. The same core ideas apply to both, so the jump for a developer isn't too intense. Perhaps the largest difference is that Flex has XML layout files which is a nice plus (although many abuse the capability of injecting logic into it as well). JavaFX is the Java-world answer to Flex, so you may want to play around with that first since it will be more familiar.

Draggable buttons in Java Swing

Hi,
I want to develop an application in Java Swing. The application I am going to develop is an application for developing other applications. I want my application to include a button which also acts as a drag and drop UI element. For example, I want my application to include a button for adding a picture. There are 4 buttons of different pictures. If a user wants to add a picture he can either click on one of these buttons and that picture will be added somewhere on the screen or dragging this button and drop it and that picture will be added where he dropped that button.
Could anyone please tell me
1. If I can develop an application which includes Drag and Drop UI element if I develop it in Java Swing
2. If a button (or other UI element) can act as both a button and a drag and drop element if I develop my application in Java Swing
3.
Could you please tell me where I can find some screenshots of applications which has been developed in Java Swing? I am not familiar with this program and I am not that good at programming, so I would like to get some impression of how it might look like.
Thanks in advanced

1. the good thing about Swing is that it is very flexible and with clever programming you can do just about anything. The problem is that depending on your requirements, this could require a great deal of programming that can be very hard to implement such that it works properly on all popular platforms (windows, linux, mac).
2. see 1.
3. Swing applications are "skinnable", you can give them a great number of different appearances. The default is to give the application a system look and feel, so they look pretty much like any other application for that platform. This means that when you run your application on Windows, it will look like a Windows application, if you run it on a Mac it will look like a Mac application, etc.
I am not familiar with this program and I am not that good at programmingThat is quite a problem, because Swing is not the easiest API around. It requires a solid knowledge of Java and Object Oriented Programming in general as the entire API is based heavily on OOP concepts. To get a better idea of Swing, read through the Swing tutorial here:

Is Jdeveloper itself based on adf swing or java swing?
