I request your feedback on my Swing application - juwo
Hello,
Would you like to test drive an innovative prototype called juwo/NP?
You can give me feedback and help me improve it. You can play a part in bringing out something that IMHO is a useful everyday tool.
To those who help others on this forum, I can send you the demos, and competitive analysis matrix - if you are interested. However, you would have to give me your word that (sorry, I dont know how to put it diplomatically) you will not rip off any new ideas nor forward the links. Also I want to avoid sending demos to competitors so please tell me if you work for one.
Several of you have helped me through my Swing obstacles in developing juwo/NP by answering my queries - philip74, JayDS, camickr, hiwa and others. Thank you.
Unfortunately, progress has slowed.
(see http://juwo-works.blogspot.com/2007/03/i-need-your-advice-startup-failing.html). So I have decided to release it anyway. Basic functionality is complete. However some people say it is not user friendly. Also mouseClicked() fails on JDK 1.6.
What is juwo? (http://juwo.com)
A "Swiss Army knife" piece of software that gives more power to consumers to structure audio, video and text as a bullet list, to more easily index and annotate them, and to share the lists with others. Its benefits extend to multimedia as related to more enriching broadcasts, collaboration and organizing.
thanks,

gives more power to consumersSounds like you're still trying to market it. I think that you can't really interest people (and create a good viral "word of mouth") by keeping everything so closed. I understand that you are afraid of being ripped off by the competition, but if you're always one step ahead of them, it doesn't matter that they copy your old features, as long as you're constantly producing new ones.
I'm looking at the screenshot on the site and what exactly am i seeing? Pixels and lines? It doesn't really make me want to download and try it out. And these days, if one look doesn't stop the casual browsing user, than he's gone.
What i'm trying to say is - don't be afraid to put fully functioning demo on your site and all the best screenshots (in the original resolution) that you have.

Using guitar amp sims live onstage... requesting your feedback
I know this is mainly a recording forum, but I expect a few of you out there are using amp sims live. So I've about a dozen gigs now and it's been OK for the most part. I also use Logic to run backing tracks, and I've been using different amp sim plug-ins on live guitar tracks to test them out and see what works best. For the most part I'm using Guitar Amp Pro, but I'm also trying Amplitube 2 and Guitar Rig 3. In general, I've had comments from FOH audio techs saying that my tones are pretty good, but there's always seems to be a bit of harshness and thinness in the tone that is not apparent in my headphones at home, and if anything I tend to reduce the treble and presence in all my patches, below that of the factory presets anyway.
I mainly play through the monitor systems at gigs, and am looking at different in-ear options, but last weekend I played a venue with limited on-stage monitor capabilities, so I made provisions on my own. I split off the stereo signal coming out of my Firebox interface and went into a little Mackie 1202 mixer, then into a Crest stereo power amp, then into my Vox 4x12 stereo guitar cabinet. You can't run a processed guitar signal back into a regular guitar amp head as this combination sounds like ka-ka, understandably, because the amp sims have already processed what the amp would then process a 2nd time. Anyway, I ran the EQ's on the mixer totally flat, so in effect I was sending the uncolored original sound to the cabinet.
Surprisingly, in this new configuration my tone was actually very good and "amp-like" sounding. My theory is that the 4x12 cabinet, not having a horn or high frequency driver, naturally removed any high end harshness with it's limited frequency response (it's probably about 8Khz bandwidth I'm guessing). I might have expected my tone to be muffled, so either I'm running too much high end in my patches or what, but it's no wonder that a monitor or FOH loudspeaker system with separate high frequency drivers would sound the way they do. My next thoughts are to maybe test running a low pass filter on the output strips in Logic to roll-off frequencies above 8kHz or so, to limit what gets fed out to the monitors and FOH.
Another theory about the thin sound is due to the fact that in an amp sim environment on-stage, there really isn't any air moving speakers like in a true mic'd up guitar cabinet on-stage. In terms of amp sim preferences, I find that Guitar Amp Pro is not as detailed or warm as the others, but it can be tweaked for acceptable higher gain tones and some really nice clean tones. I think in general, Amplitube 2 has the fullest fattest tone in some of their amp models, and while Guitar Rig 3 has some really nice models which sound fine in headphones or studio monitors, they seem to sound the thinnest live of the three sims I've tested.
I know guitar tone is a very personal thing and what sounds good to one person may sound like crud to another, but what generalities and experiences have some of you had? I think we're just on the tip of a revolution in live guitar, what with the new Stomp IO and Rig Kontrol products coming out, just to name a few... Also, how are some of you finding the latency issues that are still hindering this technology to some degree? Many thanks in advance!hey thanks for the responses guys! I usually get notified via email when a reply is posted but that didn't happen for this post (?). Anyway, great advice, but in the meantime I've actually managed to make a dramatic improvement in my onstage tone and it was very simple, and logical too. The first rather embarrassing point is that I tried setting up my tones with different sets of headphones and whoa what a difference. One would expect that different headphones will all sound different (as it is with loudspeakers) but the Yamaha headphones I was previously using removed pretty much every bit of high-end harshness that I was hearing on stage through the monitors, so what I thought was a good sound in reality was NOT. With my new BeyerDynamic earbuds (which I will be using as in-ears onstage soon) I heard pretty much exactly the same harshness that the Yamaha's were masking.
The fix to this was actually pretty simple: in the cabinet simulators of the plug-ins, I simply moved the mic to "off-center" instead of "on centre" where I had the majority of my patches saved as. Other than maybe a little less presence and treble, the tone was instantly 100% better. The funny thing is, from all the live shows I've done I always position the mic off-centre because it sounds better, doh!
I've played 4 shows since and 3 of them were festival style with great quality monitor rigs and my guitar absolutely rocked when on high gain tones, instead of giving my bandmates and the first few rows in the audience a very close shave The tone was very punchy, fat and "amp-like" and I was even getting some controllable feedback from the wedges. The guys in the band and even some FOH engineers commented that I had great tone so I felt alot better about the whole thing. The other show was a club with cheap monitors and while the sound was nowhere as good, it still was not harsh like before.
I admit that my overall tone is maybe still not quite as dynamic as it could be and there's a minimal (but almost unnoticeable) amount of latency, but overall it sounds like a guitar should, and I've heard many players with good quality amp rigs that sound much worse. I'm going to continue with my "ampless" crusade (no hard feelings jnashguitar haha!) and as technology improves I'm confident I'll continue to zero in on that elusive holy grail of guitar tone that every guitarist can attest to. That's the thing with guitarists, we think we have achieved the perfect tone, but after a few months we start looking again, but that's what makes it fun, buying new toys, trying new things. Good tone is everywhere! -
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. -
Hello guys,
I need your help about a question.
In the next days I'll develop a java application (swing application) for a customer.
What I need is to forbid possibility to copy this application on other pc, so I need some license system.
How can I bind installation of application (that is running of jar) on a specific pc and forbid to use it on other pc?
I need to do it without key device, but via software.
What's best solution for this issue?
I would appreciate any help,
Thankssnic.snac wrote:
How exactly is that going to keep a user from using multiple copies on a single subscription?It isn't. And my message is that it isn't worth worrying about this ...
The business "requirement" you have is usually not "how do I prevent my customer from making multiple copies" or "how do I prevent people from copying my application illegaly". Your requirement is (or should be) "how do I make more money with this".
History has tought us that focusing on making the software hard-to-copy is a bad idea because the cost of making a reasonably well-working copy-protection is very high and even those are easily broken (it need only be broken once, then everyone can get a copy).
Now if you make buying the software actually provide some additional value (automated, timely updates; online support; access to a feature-request queue; ...) and keep the price reasonable, then "copying + using only half a product" becomes more "expensive" to the user than "buying and getting the full advantage".
I have to agree, 'though, that in the case of custom-built software for a single client that's not really relevant. I'd agree that you should simply request that they pay enough money so that you don't have to worry about copy protection. Maybe offer them the source if they do, so that they actually get some value out of it (see the theme? providing value for the money helps you get the money). -
Running Multiple Swing Applications
Hi There!
Is it possible to run a Swing program inside another Swing program!
(Example: A Swing animation etc).Thanx for your feedback!
What I mean is, say you have a Swing
e a Swing animation which is a seperate application,
suppose if I wanna use it in another application, how
should I take it (or call it).Like I said: it depends on your design.
What class is the animation component. Is it its own class? Does it extends JFrame, JPanel, JComponent, ... ? -
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,
Nishanth.CIt 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.

Hello everyone,
I need some help regarding a swing application. I am not able to syncronously update the counters and labels that display on my Swing GUI as the application runs in the background.

s.setVisible(true);
}//end of main
}//end of class SwingAbove I have given the skeleton code of my application........ Please tell me how to update the GUI syncronously...
Please its a bit urgent...............
Thank you very much in advance
chaitanyaFirst 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().

Certificate support in Java Swing application
Hi There,
I am new to this Certificate thing and running into issues! Would appreciate for all the help and please ignore for any stupid questions.
Here is my scenario.
1. I do have a client server application and client is a java swing application which connects to a Server application (Using Jetty 4.2.22 as embedded server)
2. Initially, it had a self signed certificate but goal is to support third party certificate (i.e import in the server and then show warning to the client during login)
If somebody has already done this or point me to some example (using Jetty APIs) that would be great help. If not, here is what I am trying to do and some questions.
1. I tried to get some free SSL certificate from the web and imported into the server's KeyStore.
If I do a list from the server using Keystore, this is what it looks like
keytool -list -keystore /tmp/keystore -storepass genview
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 2 entries
self, Dec 3, 2008, PrivateKeyEntry,
Certificate fingerprint (MD5): 0D:58:E8:77:89:09:F8:2B:37:64:37:D5:03:AD:C9:0B
rapid, Jan 6, 2009, trustedCertEntry,
Certificate fingerprint (MD5): 64:9C:EF:2E:44:FC:C6:8F:52:07:D0:51:73:8F:CB:3
QUESTION 1 : why the third party certificate's entry as "trustedCertEntry"? Is it always like this? Do I need to have only one certificate at a time? (If so, just remove the self signed and have 3rd party one)
My Jetty server comes up but when I connect from Client Swing App, the "getServerCertificates()" method only returns one entry i.e self signed one but not the third party one.
I am using like this
URL url = new URL("https://127.0.0.1:port");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.connect();
Certificate[] certs = conn.getServerCertificates();
Is not this API supposed to return all the server's certificate?
Please guide me or instruct me what to do.
Thanks,

How can I unit test my Swing application?
Hi All,
In my application I came across a situation where I have to automate the unit testing of my application.
Using my application user can able to draw polylines and rectangles on a BufferedImage added to a JFrame.
Can any one please help/suggest me, how to automate the drawing process (this process consists of drawing the polylines with mouse and few action/mouse events)?
your help will be highly helpful to me.
SatyaWhat exactly will that unit test prove? That you can mock the drawing of lines?
Unit test are supposed to test certain parts of your application code - I'd concentrate on unit tests that are actually useful and for example in the future can help to catch regressions.
If anywhere you can get help creating unit tests of this magnitude, I'd look in the unit testing support for Swing applications. Google for "java swing unit test" to see what you can come up with. Probably you'll need to create some plumbing yourself to make custom painting unit-testable; perhaps you could do something with painting to a BufferedImage in stead of to a Swing component for example. -
How to create the digital clock in java swing application ?
I want to create the running digital clock in my java swing application. Can someone throw some light on this how to do this ? Or If someone has done it then can someone pl. paste the code ?
Thanks.hi prah_Rich,
I have created a digital clock you can use. You will most likely have to change some things to use it in another app although that shouldn't be too hard. A least it can give you some ideas on how to create one of your own. There are three classes.One that creates the numbers. a gui class and frame class.

How can I select a smaller font for all components of a Swing application?
The default size of font in Java Look and Feel is 12, how can I change it to 10 globally for my Swing application ?
Thanks for your help.
HelenIt is not very simple because all components don't use the same fonts and if you don't want to subclass the l&f you can do this :
after setting the l&f (in the main for example)
Font f = new Font("dialog", Font.PLAIN, 11);
UIManager.put("MenuItem.font", f);
UIManager.put("Menu.font", f);
UIManager.put("MenuItem.acceleratorFont", new Font("dialog", Font.PLAIN, 10));
UIManager.put("Label.font", f);
UIManager.put("Button.font", f);
UIManager.put("ToggleButton.font", f);
UIManager.put("ToolTip.font", f);
UIManager.put("List.font", f);
UIManager.put("Table.font", f);
UIManager.put("TextField.font", f);
UIManager.put("ComboBox.font", f);
UIManager.put("RadioButton.font", f);
UIManager.put("CheckBox.font", f);
UIManager.put("RadioButtonMenuItem.font", f);
UIManager.put("CheckBoxMenuItem.font", f);
UIManager.put("TableHeader.font", f);
UIManager.put("Spinner.font", f);
UIManager.put("Panel.font", f);etc...

Thanks in Advance.Thanks Luca for your time,
we have deployed application in tomcat and changed the home page of tomcat to our application home page(html page). and url is http://10.1.1.145:8080/
Application home page contain link to jnlp. so whenever user click on link (in home page) then jnlp will execute and launch the swing application.
do you need some more clarification?
below is the home page(html).

Is there any Open source Reporting Toll for using in swing application ?
Is there any reporting system like crystal report or any thing for report generation. Using JTable class it is so time taking job. I have downloaded Eclipse with crystal report embedded, and have created a report but can not integrate the report with JFrame with any menu item action. All the code i got releted to JSP. and few code get that are using
//Crystal Java Reporting Component (JRC) imports.
import com.crystaldecisions.reports.sdk.*;
import com.crystaldecisions.sdk.occa.report.lib.*;
//Java Imports.
import javax.swing.*;
public class JRCViewReport {
private static final String REPORT_NAME = "JRCViewReport.rpt";
public static void launchApplication() {
try {
//Open report.
ReportClientDocument reportClientDoc = new ReportClientDocument();
reportClientDoc.open(REPORT_NAME, 0);
//Launch JFrame that contains the report viewer.
new ReportViewerFrame(reportClientDoc);
catch(ReportSDKException ex) {
System.out.println(ex);
catch(Exception ex) {
System.out.println(ex);
public static void main(String [] args) {
//Event-dispatching thread to run Swing GUI. This is good practice for Swing applications
//to help ensure that events are dispatched in a predicatable order.
//For more information on using this method, refer to the SUN site below for more details:
//http://java.sun.com/products/jfc/tsc/articles/threads/threads1.html
SwingUtilities.invokeLater(new Runnable() {
public void run() {
//Hand-off to worker function to start application.
launchApplication();
}Also there is one file ReportViewerFrame.java
but the error is "*com.crystaldecisions.reports.sdk*" not found
Please help ..........................................................I have already use Jasper Report. Thakns a lot for your suggestion. Now I think i have solved your problem...... View the code.. this code will not open the JasperViewer but from the background it will be printed and after calling the printing function you can save a data in the database ------------------------
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
Connection con = Database.getConnection(); // your database connection
jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, con);
for(int i=0;;i++) { //print all pages
try{
JRPrinterAWT.printPages(jasperPrint,i,i,false);
}catch(Exception e) {
break;
}
