Using JavaFX to rewrite GUI layer for Java Desktop Swing application

From the faq's on javafx.com I read the following:
I currently build applications in Java. Can I reuse my Java libraries in JavaFX Script?
Yes. You can leverage the power of Java by using any Java library within a JavaFX application.
This way you can preserve your investment in Java and use JavaFX to build engaging visual experiences.
Can I use JavaFX to develop a user interface for my Java program?
While it's easy to write your application in JavaFX and call into Java where necessary,
the inverse - writing a Java application that calls into JavaFX for the user interface - is not yet true.
We expect this to be addressed in the near future.
* Perhaps I'm missing something, but I do not see the difference between the two questions, but they give completely different answers?
* We have a swing application that we might want to use JavaFX to replace the current Swing user interface, however, we also have alot of business logic / communications code written in
* Java that we aren't going to rewrite.
Could someone tell me why the two questions have different answers?
Thanks. Cheers.

Hi Josh,
I'm facing serious issue trying to invoke a javafx class from my java code. Could you please suggest a way to do it. Even hacks would be ood enough for now.
I have created file Clock.fx. When run individually from my IDE (i'm using NetBeans) it works fine. But when i try to invoke it from a java class in project in throws exception.
public static void main(String[] args) {
ScriptEngineManager manager = new ScriptEngineManager();
JavaFXScriptEngine fxEngine = (JavaFXScriptEngine) manager.getEngineByName("javafx");
System.out.print("created fxEngine");
try {
Object o = fxEngine.eval ("Clock { property: \"Clock\" }");
fxEngine.invokeMethod (o, "create");
} catch (Exception ex) {
ex.printStackTrace();
I get following exception
Exception thrown in JavaFX pretty printing: java.io.FileNotFoundException: \tmp\___FX_SCRIPT___.fxdump from StringInputBuffer (The system cannot find the path specified)
Exception thrown in JavaFX pretty printing: java.io.FileNotFoundException: \tmp\___FX_SCRIPT___.fxdump from StringInputBuffer (The system cannot find the path specified)

Could you please give a solution to it. I would be obliged.

Deployment issues-java desktop database application

hello,
i'm vasant...recently visited an online tutorial for creating java desktop database application
here is the URL [http://www.netbeans.org/kb/docs/java/gui-db.html#running-outside-IDE] ...
everything works fine...when building and executing the application from within the NetBeans IDE..6.7
but as instructed in that tutorial...when I tried to run the .jar file after exiting the netbeans IDE, it didnt run...
infact direction has been given in that tutorial for this in the last section....which says that i've to start Java DB from outside the Netbeans IDE...that's where difficulty arises....
i've no idea how to start Java DB manually...
i'd really appreciate if nybody der could...help me out plz
thanx

nevertheless...i repeat my question...
there's a tutorial at this link...[http://www.netbeans.org/kb/docs/java/gui-db.html]...in it is described how to create a java desktop database applicaiton...
at the end of the tuorial there is a section called: "Building and Deploying the Application"
in that section they have instructed to exit netbeans IDE and try and run the application outside it...which is not happening
the reason they say is that i've to start Java DB from outside of the IDE...that is wat my problem is ..
i dont know how to start Java DB from outside the Netbeans ide...You are not telling us anything.
If I tell you "my automobile doesn't work" how do you know what is wrong. Instead I need to tell you one of the following.
1. The engine didn't start.
2. The wheel fell off.
3. The engine caught fire.
4. When I went to the driveway the car wasn't even there.
When you "run" something then something happens. When I run notepad from a console window if notepad is not in the path then I will get an error about command not found. if it is in the path then the command executes and notepad pops up. Even if I don't see notepad pop up I know that the command seemed to execute from the command window.
The above are examples of describing what you did and what did happen. In detail.
"It doesn't work" provides neither detail about how you ran it nor what did happen when you did attempt to run it.

Set a default Font for a whole Swing application?

Hi,
Is it possible to set "Courier" as the default font for a whole swing application?
I seem to have gotten lost here, could someone give me some pointers please?
Thank You,
-Uday

So it needs to be done right at the beginningYes.
Is there a code sample i can look at for reference and a standard way of doing this.I've seen examples posted in the forum the use the UIManager.getDefaults() method and then iterate through the defaults looking for all properties that end with ".font" and then replace the font as required.

How do I rewrite current code for java 1.3

Basically compile it under Java 1.3 and see what complains. I've done several projects that compile under 1.2, 1.3, and 1.4.

Setting default volume level for Java Desktop

Hello,
I am running Sol 10 11/06 for sparc. How do I permanently set the default volume level for the Java desktop? If I change the volume manually and "save settings" on logoff, the saved setting is not saved after a reboot, after which I have to set it again.
Thank you......

Annoying, isn't it?
Unfortunately the only thing you can do is lower your system volume before opening those pages. The volume could be controlled by the Web page author but most are clueless.

How to open the link in new firefox window for web desktop based application? Or how to open the mail/website/rss link in new firefox window

I am using the firefox 3.6. My problem is that I am using the web desktop and few web desktop based application directly opens link. If I click on rss link than it opens in same window, so no longer access to web desktop. I want to open any kind of link in new window instead of same window. I have tired to change the value of browser.link.open_newwindow, browser.link.open_newwindow.restriction but doesn't work. Also gone through the https://developer.mozilla.org/en/window.open but not sure where to do this in web desktop based application or firefox where we connect the web desktop?
Is there any way to open the link every time in new firefox window?

Hi Joseph,
the HTMLB link object misses the support for onClientClick through the tag lib, see hbj:link without onClientClick ? and OnClientClick Event for Link HTMLB Component for similiar problems and workarounds.
With this workaround, you can call for example an AbstractPortalComponent, implement doOnNodeReady (with an empty doContent method) and return the PDF, settings the content type on the http before etc.
Hope it helps

Tuning GC parameters for a large Swing application

Our Swing application suffers from periodic out-of-memory errors. We have been trying to tune the application with limited sucess.
The problem is full GC is called only when it is close to the maximum memory. As a result when it reaches the max-heap-size values, it takes a long time to complete GC and the application hangs.
My current jnlp settings are as follows:
<j2se version="1.5+" href="http://mydomain/myapp/jre" initial-heap-size="64M"
max-heap-size="384M"
java-vm-args="-verbose:gc -Dsun.java2d.noddraw=true -XX:NewSize=16m -XX:SurvivorRatio=8 -XX:YoungGenerationSizeIncrement=5 -XX:TenuredGenerationSizeIncrement=5 -XX:AdaptiveSizeDecrementScaleFactor=5" />I am looking at ways by which the tenured generation too gets garbage collected peiodically. Is there a way by which I can achieve this?

for first one, try paintImmediately(rectangle) method. for second one, i guess Graphics g = panel.getGraphics();
g.drawRect(....);

IMP:ClassCastException while using File upload UI in Webdynpro for java

Hi All,
I have used a FileUpload UI element in my screen , which is working fine for only the first time we upload a file. If we try to upload any file with out refreshing the application , a ClassCastException is being thrown. Please help me in resolving the issue.
Thanks in advance.
Srikanth

Thank you!!
1. But when i use the File Upload UI and try to use the 'data' property to retrieve the bytes i am getting a null pointer exception meaning the data is not being picked up by the UI even though browsed file has data.
2. How I am I supposed to set the 'Resource' property while downloading a PDF which has UTF-16 text and picture??
Note: I have done the same scenario using WD04 java without any trouble.

Using the Portal Single Sign-On for java applet clients

Hi
We have a task to build a java applet working within a portlet and comunicating to some session EJB(wrapped BC4J) running on the OC4J. The applet is presumably connecting to server via RMI. This connection should be restricted to some groups of portal users.
When a user is entering the applet he is supposed to be already logged into the Portal.
There is a lot of information on building custom secure portlets using only a pure HTML(same as JSP) client whith the help of the Portal Single Sign-On.
But, is it possible to use the Single Sign-On for establishing a secure RMI connection from applet to OC4J without entering a password in the applet once more?
Yuriy

Perhaps you can write a small JSP page or PLSQL
web procedure that will grab user name from
the SSO Server (via SSOSDK/mod_osso)
and invoke the applet with encrypted user name.
The applet will receive the encrypted username
and decrypt it to get the clear user name.
This help to get Single Sign-On.
To make sure that environment is secure, encrypted
user name parameter should have random salt,
user name, and time stamp to prevent replay attack.
Applet must make sure that the encrypted users name
time stamp set by the JSP/PLSQL page has value
within a reasonable time limit like 5 minutes

Gui support for java

hello friends,
i am new to SUN fortran compiler. i have installed it. But what i have heard it has a gui interface to write fortran code and debug it. But i cant find it. is my installation incomplete or i am missing something? Command line compilation is working fine.

There should be a sunstudio command. That will start the IDE (integrated development environment), which has an editor, debugger, and performance analysis tools.

How Get GUI Cycles for a Compute-Bound Application?

Mine's not even quite compute-bound:
o it sleeps for a millisecond in the loop
o it does Thread.yield()
..but still the GUI never seems to get enf cycles for me to hit the stop btn.
I didn't find anything in SwingUtilities.
Thanks,

You're almost certainly doing work on the event dispatch thread.
