Distributed Swing Applications??

I'm not sure if this belongs in the swing or the RMI sections, but since I think it has a little more focus with GUI development I posted here - sorry if it is off-topic!! Here is my problem:
I am interested in building a desktop application to house registered java applications on remote machines. I am interested in pulling in developed and existing applications that are to be run remotely, and tieing them together under one central view. The best software analogy I can come up with would be an xserver/xclient relationship between java applications.
The functionalities I need are:
local views of each distributed application, encapsulated inside one large (local) java desktop.
Distributed performance... half of the applications are developed with JNI interfacing and ARE machine dependant.
The ability to stop and restart server applications on-the-fly, in order to patch and update server functionality.
Minimal rearchitecture of existing java applications.
I have been bouncing around ideas, but there are only a few that really seem to stick out.
One solution would involve rearchitecting existing applications to decouple the view and the event handlers. So, my Model-View-Controller has local views and controllers, but remote models to maintain remote state (and computational performance). So then, each event handler should update the GUI correctly, but also update remote state information on my server.
I guess another solution would be to intercept these applications at the X-level and re-assign their graphics contexts inside my java application. I haven't pursued this option yet, because I figured there was a better pure-java solution.
My current test solutions have been implemented utilizing RMI, and I think that is probably the way to go, but I am open to opinions. While rearchitecting these applications to exist within a client/server relationship is allowable, it is not preferred. Thanks for all the help!!

Why don't you just open up like five SSH consoles, or
remote desktop connections, and be done with it?
Ok, do you have motivation for being against
client/server... as you could build a server that
acts as a controller for your swing GUI. The server
would talk to the apps, and coordinate the views in
the swing GUI.I don't want to just use consoles and x-forwarding, because the end result should be a desktop that will be "easy-to-use" for people that are relatively unfamiliar with the application suite.
I agree with the second choice; and think that I'll probably end up going that route. Is another good implementation besides a MVC architecture, that doesn't require me to rearchitect existing apps??
Thanks!

What is the best way to distribute your swing application:

I have developed a application that connects to data base and it containes the functionality to manage the invoices and receipts system, but i am scare to distribute it by building it to jar using the netbeans build option , it runs fine but when i extract the jar file back i m scare that any one can easily decompile it using JAD and get the database credentials , please tell me the best way to distribute the application so that reverse engineering the application will not be possible please tell me that :(

Decompiling is unnecessary. All somebody would have to do would be to sniff the transmissions between your application and your database; the credentials are sent unencrypted.
So the problem is not that somebody could find out the database credentials, the problem is that your database exposes itself to the internet. And if anybody does find the credentials through any method at all, then you've got a problem.
And by the way if you distribute your application with the credentials hard-coded, then that makes it difficult for you to change the password if it does get compromised, because then nobody can use your application any more. This is a bad thing because one of the first things you should do when your system is compromised is to change the access password.
So really the best way to distribute this application would be to write it so that it connects to an application which runs on your server. This server application would communicate with the database, which would make it unnecessary for the database to be visible from the internet. Your Swing application would communicate with the server application via some kind of web service protocol.

The best way to distribue att Swing Application?

How can I do this?
If I give it out in .class format only them with J2SE will be able to run it..
how do you do it?
Tanx for any help!

Hi,
it depends on how you distribute your Swing
application. If you distribute it on CD, then include
a JRE on the CD.
Or you could try to convince or attract your users to
download the latest JRE themselves before the first
usage of your application.
If you distribute your application through the web,
put two buttons on a HTML page, one linking to a JRE
download (with some installation instructions before
the start of the download), the second button being a
JavaWebStart button for your swing application.
Or you could use InstallAnywhere and bundle JRE and
application into an installer.

How to give Common Background color for all JPanels in My Swing application

Hi All,
I am developing a swing application using The Swing Application Framework(SAF)(JSR 296). I this application i have multiple JPanel's embedded in a JTabbedPane. In this way i have three JTabbedPane embedded in a JFrame.
Now is there any way to set a common background color for the all the JPanel's available in the application??
I have tried using UIManager.put("Panel.background",new Color.PINK);. But it did not work.
Also let me know if SAF has some inbuilt method or way to do this.
Your inputs are valuable.
Thanks in Advance,

It is not the fault of NetBeans' GUI builder, JPanels are opaque by default, I mean whether you use Netbeans or not.Thank you!
I stand corrected (which is short for +"I jumped red-eyed on my feet and rushed to create an SSCCE to demonstrate that JPanels are... mmm... oh well, they are opaque by default... ;-[]"+)
NetBeans's definitely innocent then, and indeed using it would be an advantage (ctrl-click all JPanels in a form and edit the common opaque property to false) over manually coding
To handle this it would be better idea to make a subclass of JPanel and override isOpaque() to return false. Then use this 'Trasparent Panel' for all the panels where ever transparency is required.I beg to differ. From a design standpoint, I'd find it terrible (in the pejorative sense of the word) to design a subclass to inconsistently override a getter whereas the standard API already exposes the property (both get and set) for what it's meant: specify whether the panel is opaque.
Leveraging this subclass would mean changing all lines where a would-be-transparent JPanel is currently instantiated, and instantiate the subclass instead.
If you're editing all such lines anyway, you might as well change the explicit new JPanel() for a call to a factory method createTransparentJPanel(); this latter could, at the programmer's discretion, implement transparency whichever way makes the programmer's life easier (subclass if he pleases, although that makes me shudder, or simply call thePanel.setOpaque(false) before returning the panel). That way the "transparency" code is centralized in a single easy to maintain location.
I had to read the code for that latter's UI classes to find out the keys to use (+Panel.background+, Label.foreground, etc.), as I happened to not find this info in an authoritative document - I see that you seem to know thoses keys, may I ask you where you got them from?
One of best utilities I got from this forum, written by camickr makes getting these keys and their values very easy. You can get it from his blog [(->link)|http://tips4java.wordpress.com/2008/10/09/uimanager-defaults/]
Definitely. I bit a pair of knucles off when discovered it monthes after cumbersomely traversing the BasicL&F code...
Still, it is a matter-of-fact approach (and this time I don't mean that to sound pejorative), that works if you can test the result for a given JDK version and L&F, but doesn't guarantee that these keys are there to stand - an observation, but not a specification.
Thanks TBM for highlighting this blog entry, that's the best keys list device I have found so far, but the questions still holds as to what specifies the keys.

How to get mouse wheel action in my swing application?

Hi
In my mouse, i am having mousewheel to support scrolling.With the help of the wheel, i can scroll the pages in IE browser or any other appliction.
In swing application ,i have scroll bar inside a JFrame.I want to have mousewheel action in my swing application to support scrolling.
any idea ???
Thanks

As far as I know,there is no facility for detecting mouse scrolling wheel in JDK 1.3.
Check it in the later releases of JDK.

I used janela to validate the generated jnlp file. It was valid. I also checked the tomcat access log, it showed that the Test-1.0-SNAPSHOT.jar file was accessed correctly (with a 200 return code).
Can anyone help me what was the problem?

Please its a bit urgent...............
Thank you very much in advance

First off, note that this question should have been posted in the Swing section.
GUI events run in a separate thread (the AWT / Event Dispatch Thread) than your program.
You should be invoking AWT/Swing events via SwingUtilities.invokeLater().
If for whatever reason you want to have the program thread wait for the event to process
you can use invokeAndWait().

Problem with "find" mode in adf/swing application

Hi all,
I'm working on ADF Swing application which uses MS SQL Server 2005 (JDeveloper 10g 10.1.3)
I think that my issue might be well-known…sorry if it has been already discussed somewhere else…
I have a problem with the “find” mode for a detail panel in a master-detail form…(To make it clear the “find” mode is switched on when clicking on the special button on a navigation panel).
So this mode works well in a master panel, but it demonstrates strange behavior on a detail panel, i.e. it takes me two attempts to find the necessary child object and it doesn’t switch back in a simple way from this mode to the normal mode….say if we are in the department 10 (Dept is a master form) we can’t simply find KING employee (Emp is a detail form)…is there any workaround for this?
Thanks in advance. Alex.

Problem in Opening HTML Page in Internet Explorer from my Swing Application

Hi,
I am opening a HTML file in Internet Explorer from my swing application.I am using the code given below
private final static String WIN_FLAG = "url.dll,FileProtocolHandler";
private final static String WIN_PATH = "rundll32";
String cmd = WIN_PATH + " " + WIN_FLAG + " " + url;
// url is HTML file Path
Process p = Runtime.getRuntime().exec( cmd );
Here there are two things i need to address ...
1)The HTML file is opening up,but it always opens behind the swing application,that makes me every time to maximize the HTML file after it being opened up.I want to open it in front of the Swing Application.I need to implement "Always On Top" functionality for the html page.
2)Whenever i trigger action to open different HTML page,it opens in new Internet Explorer window.
I need to open it in same IE window.
how to solve out these problems ??? any help would be greatly appreciated .Thanks in advance.
