Weird problem with java.awt.Color

I have a Compiled C program that launches a Java program. This java program always throws an UnsatisfiedLinkError when I attempt to construct a new Color object, unless the owner of the C program is one particular user and the group is admin. No other combination works.
Any ideas?

in nt & 2000, each user can have his/her own classpath - i assume that this is the same of unix. have you looked at whether the various users have the appropriate classpath settings?

Problem with java.awt.MouseInfo or java.awt.event.*;

I have a problem with the MouseInfo class. I think.. because in my mousePressed(MouseEvent event) method, I have this:
     public void mousePressed(MouseEvent event) {
          pInfo = mInfo.getPointerInfo();
          point = pInfo.getLocation();
          pointX = point.getX();
          pointY = point.getY();
          System.out.println("pointer is at: (" + (int)pointX + ", " + (int)pointY + ")");
     }I think you all could figure out what this does. I declared the variables at the top and I implemented MouseListener... when I click it doesnt tell me the X and Y coords.
Alright, thanks. Any help appreciated.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MouseExample extends MouseAdapter implements Runnable {
    @Override
    public void mousePressed(MouseEvent event) {
        int x = event.getX();
        int y = event.getY();

Weird problem with java environment

Hi
I have been working on a project using JRE 1.5.0_06. We are developing everything on netBeans platform. Until two days ago everything was going fine when suddenly both the system and the netBeans have begun working weirdly. These are the problems:
1) When I make changes in a java source file and compile it using javac, those changes are not being reflected in the class file. In other words, on running the class file, I'm getting the older version. i can't make a thing out of it. Please help me out as my deadline is approaching. I tried both from inside netbeans and from the command line. The OS i'm using is windows XP. Further, netbeans is showing more strange problems. Even while debugging, it is skipping some lines in the code which have been modified - seems to be the same problem - those lines are not being compiled into the class file. I've been careful to check that I am using the correct class files. Did anybody had this problem before? Is it a bug in JRE or something like that? Do I have to reinstall JRE?
Thank you in advance,
venkat.

thanks....for your prompt reply.. I reinstalled both jre and jdk. But I could understand the problem. We have to compile using the java executable in jdk rather than jre.

Rendering of an 8Bit-tiff with java.awt produces crap

Hi Folks,
i do a downsampling of tiff images. The source tiffs are colored 8 Bit greyscale with a 256 color-table. Now i have 2 possibilities to resample with java.awt:
1. the target-tiff is of 24Bit true color:
BufferedImage objDownsample = new BufferedImage(iTargetWidth, iTargetHeight, BufferedImage.TYPE_INT_RGB);The result is a perfect looking, but oversized tiff with 16 million colors each pixel.
2. the target-tiff is of 8Bit like the source-tiff:
BufferedImage objDownsample = new BufferedImage(iTargetWidth, iTargetHeight, BufferedImage.TYPE_BYTE_INDEXED,(IndexColorModel)image.getColorModel());The result is a small sized tiff image of 8Bit. Problem: it now has visible vertical stripes of two colors (which both composed result the source-color i assume).
Does anybody know what's wrong here and how to retrieve the 8Bit color-image without stripes?
Here comes the whole source:
    private BufferedImage resize(int newHeight, int newWidth, BufferedImage image) {
        int iTargetHeight = newHeight;
        int iTargetWidth = newWidth;
        //Create a BufferedImage that fits
        BufferedImage objDownsample = new BufferedImage(iTargetWidth, iTargetHeight, BufferedImage.TYPE_BYTE_INDEXED,(IndexColorModel)image.getColorModel());
        //A map with all necessary rendering hints to optimize the quality of the image
        Map<java.awt.RenderingHints.Key, java.lang.Object> obj_Map = new HashMap<java.awt.RenderingHints.Key, java.lang.Object>();
        obj_Map.put(RenderingHints.KEY_DITHERING, RenderingHints.VALUE_DITHER_ENABLE);
        obj_Map.put(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        obj_Map.put(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
      // Draw the scaled image
      Graphics2D graphics2D = objDownsample.createGraphics();
        graphics2D.addRenderingHints(obj_Map);
        graphics2D.drawImage(image, 0, 0, iTargetWidth, iTargetHeight, null);
        return objDownsample;
    }Thanks

As far as I can tell, this solution only allows compositing within the component that is currently being painted. What would be nice is if I could add a custom composite to say .. a JLabel, which paints based on the colors of the underlying pixel data (ie. from its parent container). In this way you could make a JLabel that always inverts the color of what's underneath.
Here, painting to the screen using a composite allows me to get the pixels underneath as the destination raster, the pixels in the JLabel as the source raster, and what actually gets painted which is the destination output raster.
If I paint to a BufferedImage instead, the composite's 'destination raster' is the new BufferedImage's default values which are all black. Thus compositing over this would not have the desired effects described above (inverting the underlying image for instance). The missing piece when rendering to the BufferedImage is first copying the underlying screen data into a BufferedImage before painting to it. How do I do that? Something tells me it's very difficult.

Problem with java print

Hi, I'm have problems with java print (g2d). For example i want to print a String "ABC**************************DEF" on paper size 80mm width (invoice paper). I can print all that string with paper A4 size, but with paper size 80mm i have problem with that String, the result is "C*****************D" lost AB and EF.

Weird problem with JApplet

I'm having a weird problem with JApplet. So first I create an Applet with this code
public class japp extends JApplet {
     public void init() {
          Container content=getContentPane();
          JButton jb=new JButton("Hello");
          content.add(jb);
}and with this in the .html file;
<html>
<body>
<APPLET CODE="japp.class" WIDTH="650" HEIGHT="500"></APPLET>
</body>
</html>
And opened it in Firefox, it worked as expected. However, when I change the code in any way, i.e.
public class japp extends JApplet {
     public void init() {
          Container content=getContentPane();
          JButton jb=new JButton("Goodbye");
          content.add(jb);
}and compile it, it still shows the old button that displays "Hello". I've tried deleting the .class file from before and recompiling, that doesn't work. What am I doing wrong?
Thanks.

Reloading the page usually doesn't work. You will need to open the Java Console and clear classloader cache (x). You can also use appletviewer for testing purposes.

Java.awt.Color...........???

Hi.........
Why RGB colors created using a constructor of the class java.awt.Color as given below:
myColor = new Color(r, g, b);
whereas HSB colors are created using a static member function
myColor = Color.getHSBColor(h, s, b);
what is the reason behind it ???
thanks with regards........

There can't be two constructors with the same parameters (float, float, float).

Weird problems with CSS being applied to JSF pages

I have this really weird problem with my CSS rules being applied to my JSF pages. My CSS rules don't get applied unless one of the following two things happen:
- A page is reloaded (by redirecting to itself, or if there were validation errors)
- The previous page in the history had the same relative reference to the same CSS file.
If a page is newly loaded, and the previous page did not have that same CSS reference, the CSS styles will not show up. Also, if the above is true, and the page is reloaded by JSF, the CSS styles show up.
Now, my problem could be solved if I put all JSP files in the same level, but the display of the first page would still be without the CSS style applied.
Is this known behaviour? And if it is, does it have anything to do do with the way JSF handles URLs (always one level back)? Help and input is kindly appreciated!

Dude,
I tried the same
<link rel="stylesheet" href="<h:outputText value="#{facesContext.externalContext.requestContextPath}"/pages/css/default.css" />
and I got the following Jasper exception.... pointers plz ??

Weird problem with role assignment in Portal

Hi,
In our newly installed Portal for eRecruitment Production System we encounter a weird problem with assigning roles to users.
When I open User Administration and search for roles, it displays the Portal roles perfectly.
However, when I search for a user in User Administration and click on it when found, I am unable to find any roles to assign! So I am unable to find any roles, when I want to modify the assigned roles for a particular user, while the roles do exist and can be found on its own. How is this possible? Am I missing something here?
We have installed SPS 15 and use ABAP as user store. We have used reverse proxy and web dispatchers in this case.
Thanks in advance and best regards,
Jan Laros

Early problems with Java on my Macbook.

Hi, I am a former high school computer science student and I'm having problems with Java as I've recently moved from Windows to a Mac. The following is a letter I wrote to my prior computer science teacher but he does not seem to be responding. I think all you need to know is that DrawHouse and JumpingJacks are simple Java programs we made in class that utilize an object called DrawingTool (which is a graphics environment). DrawingTool is contained in gpdraw.jar and also was contained in our class' apcslib.jar. Also, FileInput is a class contained in apcslib.jar.
I basically transferred all my JAR files (apcslib.jar, etc.) from my Windows computer to my Mac. I didn't think anything was wrong or corrupted with them because they're the same JAR files that I used for my Java programs on my Windows comp in high school and when I run those Java programs now, they still work. But for some reason if I try to run, say, DrawHouse or JumpingJacks with those same programs on my Macbook, it gives me the following errors on runtime (it compiles fine).
Exception in thread "main" java.lang.NullPointerException
     at apcslib.DrawingTool.move( DrawingTool.java:456)
     at java.awt.Component.setLocation( Component.java:1705)
     at java.awt.Window.init( Window.java:289)
     at java.awt.Window.<init>( Window.java:318)
     at java.awt.Frame.<init>( Frame.java:419)
     at java.awt.Frame.<init>( Frame.java:384)
     at javax.swing.JFrame.<init>( JFrame.java:150)
     at apcslib.DrawingTool.<init>( DrawingTool.java:45)
     at apcslib.DrawingTool.<init>( DrawingTool.java:106)
     at JumpingJacks.main( JumpingJacks.java:35)
So I thought, maybe I'm not importing the JAR files correctly. But if I import gsdraw.jar or a different apcslib.jar that I downloaded from some random teacher's website on the internet (and that also happens to have DrawingTool in it) then it compiles and runs fine. So I thought, ok, maybe it's a problem with this one particular apcslib.jar that I transferred from my Windows computer. But like I said, DrawHouse and JumpingJacks run fine on my windows comp, and most ridiculous of all, I tried running Tasmania on my Macbook (which uses the FileInput class from your apcslib.jar) and THAT works fine! So to recap, I'm not importing the JAR files wrong and at times there doesn't seem to be anything wrong with the apcslib.jar you gave us and probably not anything wrong with my IDE, seeing that importing of other JAR files works fine (I'm using eclipse and/or xcode, and the same problem occurs with both). Now of course, I could just go ahead and use the apcslib that I downloaded from the internet, but it's very inconvenient since it doesn't match your own apcslib's contents (for example, it doesn't have FileInput). By the way, I've also tried adding the JARS directly to the Java Extensions instead of importing them as external JARS, but that doesn't solve the problem. I've also attached the apcslib.jar in case you think that it's somehow corrupted or something....
Do you have any idea about what could be wrong or where I should go from here?
Thanks for all your help!

Thanks for the reply, but if it is a problem with how
I'm using DrawingTool, then shouldn't it run with
errors on my Windows comp too?Maybe, maybe not. If you're doing something that's correct on one but not the other - using file names for Windows on Linux Mac), for instance.
The same EXACT source
code will compile and run fine on my Windows comp,
but run with errors on my Macbook. And if it's a bug
with DrawingTool, then shouldn't my Windows comp also
encounter the problem and run with errors?No. the DT programmer could have done the same thing, using code that's correct on Windows but not on Linux. Or there could be a difference in the Java versions on the couputers and code that's valid in the later version is failing in the earlier, or vice versa.

Problem with java apps

Hello,
I'm having a weird problem with some java apps that I'm trying to use (netbeans and frostwire). Looks like they aren't recognizing where the mouse pointer is. If I click Frostwire's window close button, it minimizes instead. The same thing is happening with netbeans, where I can't even access the menus with my mouse. I have the latest jdk and xfce4 packages installed.
Any hints on how I can fix this?
Thanks,
Gustavo

Do you use beryl ? it causes (or atleast used to cause) some strange behaviour with Java applications

Weird Problem with X6, help please!

I have got this weird problem with my nokia X6, it's display shows lines and merged colors when turned on. It started happening after I got my Nokia X6 fixed for broken screen, 15 days later after getting it fixed it started showing such display. I figured out somehow to unlock my phone while in such display horror and figured that opening a heavy app like OVI store brings back mobiles display. I don't want to send same people my mobile again. Just want to know what can be done to fix this problem. PLease Help!

Yeah, it was a nokia care center. Anyway I fixed the problem luckily. It just needed some updates. I never thought not updating can cause this problem.

Problem with Java and Windows (Mainly Vista and UAC)

Hi all,
I am having a problem with a program that I've devoloped. The program itself is packaged as a jar and I plan to deploy it across multiple platforms eventually however right now i am only concerned about windows based systems. I have made an installer for a windows baised systems using NSIS to install the software files. I made the installer as I need several java packages to be installed so the program would work (JAI, J3D, JAI ImageIO) and I also require the program to have fileassociations on windows.
I know that this is not what java is about, however the majority of the users will be on windows baised systems so I've decided that OS specific installers is the best option.
During the process I have noticed that there are several key problem with java for this type of application!
The first issue that I have come across is getting file associations to work on java. As a .jar is not an excutable it is not possible to directly associate a filetype with it in java so to overcome this I currently run the program from a .bat files and also the program requires large memory so this also allows me to run the program with -xmx. The batch file that I use is :
<code>
cd PATH TO PROGRAM
start javaw -Dsun.java2d.noddraw=true -Xmn100M -Xms500M -Xmx1000M -jar "PATH TO PROGRAM\program.jar" %1 -vram 134217728
pause;
</code>
Ok so all this appears to work fine and allows windows to have file associations and start the program and thats all works perfectly but this is a non-ideal solution. Has anyone got any advice on improving this?
The next problem that I have appears to be a problem with Vista and UAC (user access control). When a user installs the program and installs the program into the program files directory I found that the program did not work and kept saying that I did not have access to the files in the current directory. This is a problem as I read and write settings files during program execution.
On a Vista system UAC prevents file write operations into the Program Files directory unless the program has requested elevated status even if the user is a full administrator. The probem is that there appears to be no real way to achieve this under java that I'm aware of...
Has anyone else had this probem and has a suitable solution?
Any advice on these issues would realy be appricated.
Regards
Joey

Ok so i've kinda found a solution, its not ideal but its very good. I found this program called Elevate
A link to the site I got it was
http://www.wintellect.com/cs/blogs/jrobbins/archive/2007/03/27/elevate-a-process-at-the-command-line-in-vista.aspx
This program allows you start java with a UAC dialog for high access using
Elevate java -jar myjar.jar
This then allows you to have full access using java... I guess it could be dangerous but it does the job.

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.
