Windows 7 and Java

Hey,
I have been testing my applications I have written in java since Windows 7 RC's had first started being released.
Finally after installing the retail ultimate edition... the results from Java GUI related stuff is still as it was since Windows 7's first release.
Resizing of JFrame's gives a serious flicker on GUI especially when using substance look and feel, (black background beneath the standard gui)
For example, resizing net beans in xp is perfect, but resizing it in Windows 7 gives a black background and an extremely slow repaint.
I hope this gets resolved soon... is there anything being done or some sort of work around?
thanks!

hii,
nb supported Vista on "http://www.netbeans.org/community/releases/67/relnotes.html#system_requirements",
1/ be sure that's win7 is 1.st service pack for Vista, nothing else, vista core 6.0 and win7 core 6.01,
2/ xp and vista is strict only 32-b,
3/ have you win7 - 32-b, or 64-b
4/ JVM 6 for 32-b or 64-b "http://java.com/en/download/faq/java_win64bit.xml"
5/ check if is JDK and SDK correctly instaled, (JDK 6)
6/ nb correctly runs on win2003 64-b(xp core) or win2008 64-b (vista core), JVM 6, JDK 6, JDK 5,
or
7/ instal that's on xp mode

Utf-8 on Windows and java 1.4.2

There is a problem in running my application on Windows (2000, 2003, etc.) using java 1.4.2_x. The same code is working fine on Linux.
Furhtremore, the same code is working fine with java 1.4.1_x on both OS's
The application is reading an XML file and it is printing some of the values on an HTML page. If the values are in non-latin characters, with java 1.4.2_x running on Windows, they are not presented correctly.
Dejan

Then the application is not handling the XML file's encoding properly. Or else whatever it is that is "printing" (very strange term) the XML on the HTML page is not setting the HTML page's encoding correctly.
Control the encodings in the proper way and the program should work correctly on all platforms.

Compiling for Windows and Java

Hi All
This is a deff newbie question. Basically i have a program that will compile in Windows, but if I try and compile it in Linux (CentOS) then I get 48 errors all related to graphics of constructors.
It was my understanding that Java was meant to be platform independent, or is that just a myth?
Is there any way that i can resolve this, or find a tool that will show me what wont compile under linux and why?

You may be missing some jar(s) in your classpath.

There are none. What kind of problems did you anticipate?

Fonts in Windows and Fonts in Java

Hello,
Say I have in my app:
String string = "\\u09A1";
I want to display this in my app. I can call:
GraphicsEnvironment.getLocalGraphicsEnvironment().getAllFonts();
I can then iterate through these and find out which ones can display this unicode character using,
font.canDisplayUpTo(string);
My question is, are these the fonts that Java can display (from charsets.jar) or the ones installed in Windows?
I would like to be able to get lists for both of these.
Any ideas?
Cheers,
Jim

Thank you. I did read that. I was not talking about drawing text in 'Hello World' alike applets/programs.
I should give an example:
I would like to print 'H' in Tahoma, 72, Bold (Windows format) at (100, 200).
Font sizes:
In Windows font size is 72 pixels.
In Java this is equal to 96 points (72 px * 96 (scr resolution for Toolkit) / 72 (pixels per point).
Real height in Windows and Java will be 64 px.
That's fine. For some fonts this does not work.
Positioning. See example above.
According to the article you refer to in java we should use y-coordinate 200 + 72 (font size) = 272.
In fact we have :
Java text 14 pixels below than expected.
Similar things happen to other parameters Weight, Styles, etc.
I do use AttributedString and TextAttribute classes to render text
Thanks in advance.

Java for PI 7.1 EHP1 in Windows and SQL Server 2008

Hi Gurus
I try to install PI 7.1 EHP1 in Windows and SQL Server 2008. The questions is :
What version of java is the correct for this installation???
And where i can download it??
Thanks and advance!!!

Hi Aaron,
The version for PI 7.1 is 1.5, instead of the 1.4.2 of 7.0/3.0.
Anyway, for VM settings, you should refer to SAP JVM, which
is used for the PI 7.11.
Hope it helps!

String.getBytes (java) o/p different in Windows and Unix

Hi,
I was trying out the following code, which gives me a byte array from a
String object.
byte[] bytArr = null;
bytArr = <String object>.getBytes("UnicodeBigUnmarked");
System.out.println(bytArr.toString());
The output is different in Windows and in Unix. The assumed that the reason could be because Intel architecture is based on little_endian so the difference in output. I changed the code to the following
bytArr = <String object>.getBytes("ISO8859_1");
and then ran the class file by using "java -Dfile.encoding=ISO8859_1" so that the toString can also take the character encoding of ISO8859_1 rather than using the platform dependent one. Still the result is different in Windows and Unix.
What could be the reason for this? How can I correct this ? Any help in this regard is welcome.
cheers
kk

Hi Sabre150,
Thanks for the suggestion, it worked. Both the o/p shows the same if I use System.out.println(Arrays.toString(bytArr));
I am assigning full points to you. Thanks a ton for the help.
To end with I have one more question, the method Arrays.toString is introduced from jdk1.5, so if I want to use jdk 1.4 what should I use instead of Arrays.toString ?
It would be great if I can get this answer.
cheers

How to find cd rom drive in windows and unix platform using java program

Hi,
I am having the requirement of finding the cd rom drive
using java program. I do not know the label and which
one is the cd rom drive. also I want to know how many
cd rom drives are there on my system. I want the solution
for windows and unix platforms.
If have any suggestions please mail to [email protected]
Deepak

Ughhh.. I had the same problem with multi platform file-system detection
First off - Unix.
Do you know for sure you have all your drives mounted?? This could be a big problem because java will not see unmounted drives... So you can scour thru your /etc/fstab to find out which drives are available... or you can mount all and show roots... (Yuck!)... You've got timeouts and all sorts of things to worry about...
I would then shy away from the java.io.File.listRoots() on unix and rely on parsing your fs file. If a user would like to see the medium in the drive. Do a Runtime.exec and mount the drive, then you can grab the filesystem by wrapping it in the java.io.File object. ( NOTE - this will hold well for your NFS mounts as well which might be buried under other FS. So you now have detection for that as well. ) Labels are also noted in this file. Let me know if you don't know the difference between mtab and fstab....
Second - Winders.... Corney but I love saying that.
The listRoots is a good solution. As others have said CD-ROMS will not be writable. Use a combination of getName and getPath to decipher the label and mount point.
Hope this helps!

Perform Hamming window and FFT with Java

Hi all,
I am trying to apply Hamming window on my lengthy sound data soundSample[1000] with window length 100. Then proceed with FFT.
And i found that java does have the package for Hamming window and FFT. As below,
http://code.compartmental.net/minim/javadoc/ddf/minim/analysis/FFT.html
http://marf.sourceforge.net/api/marf/math/Algorithms.Hamming.html
But i hardly find an example that illustrate how to use the package in a java program. So no idea how should i use the method in package.
Please advise and appreciate if reference is provided.
Thank you.

Hi,
I have spent sometimes to study and do the coding for FFT on audio samples.
My project is to study the FFT working by performing the FFT on audio sampled data.
After this is done, then only proceed to extract the pitch value in the audio data.
Below is the coding that i have done by referring to the provided steps:
In my main, i call this method and past the retrieved sampled sound data to this method.
public static void Analyze(int[] soundSample,float sample_rate ) {
        int N = (int)sample_rate/5;
        int Number_Sample = soundSample.length;
        Complex[] fftBuffer = new Complex [2*N];
        Complex[] fftResult = new Complex [2*N];
        Complex [] lastN = new Complex [N];   // The array to save the last N sample
        int delay = 0;
        double delta = 2*Math.PI/(2*N);
        // I have no idea how can i convert my sample array to double so that it will be in the range of [-1,+1]
        while(delay <=soundSample.length){
            //Extract the 2N sample for FFT analysis and convert the data to complex number.
            for (int z=0; z<2*N; z++){
                fftBuffer[z] = new Complex(soundSample[z+delay],0) ;
            for (int i=N-1;i>=N/2; i-- ){
                lastN[N-1-i] = fftBuffer;
for (int z=0; z<2*N; z++){
fftBuffer[z] = fftBuffer[z].times(0.54-0.46*Math.cos(z*delta));
fftResult = FFT1.fft(fftBuffer);
delay = 2*N + delay;
1) I was trying to perform FFT with 2N samples then keep on looping the FFT method until 2N reaches the ends of sampled data.
But the FFT that i am working with is radix 2... It doesn't work with my 2N samples... Please teach me how should i work out FFT regardless the number of sample?
2) The hamming window coefficient i m using is based on http://www.mathworks.com/help/toolbox/signal/hamming.html . I am working on index [0:2N] ..
Is it appropriate?
3) According to your No1 steps, the acceptable frequency resolution is 5Hz. May i know what is this representing? And is it application for most of the FFT application? How can i determine the frequency resolution that i should used in my project?
Sorry for late reply as i was trying to work out the thing..
Hereby attach to your the my coding.. and hopes to have your guidance and tutorial how to extract the pitch for recording audio file with Java.
I have done the pitch extraction with MATLAB.. but Matlab as built-in FFT function...
So i m now get stucked how to perform FFT on audio sound sample regardless the N value of sound sample for FFT buffer.
Many thanks for your former advise... and
Looking forward for your replies again.
Happy New Year 2011 :)

Windows Server 2003 64bit and Java 1.5.0, does it support 64bit processing?

I have search the Sun website, Google etc but I am unable to find a definitive statement as to whether Java 1.5.0 has support for 64 bit processing when run on on Windows Server 2003 64bit?
There appears to be separate 64 bit versions available for down load on the Solaris platform but not on Windows Server 2003 64bit. Is there for a reason for this?
If some one could clarify the situation it would be greatly appreciated.

Get Native Java Window using Java Access Bridge 2.0.1 & Java 1.6 and above

I want to get the native java window (Like Java Monkey Application and Java Ferret Application) using java only, for that I tried different ways/options but unable to get the native java window and perform actions on that.
It would be really great if you could guide me for that. I am still unable to start the Java Access Bridge.
Please let me know the steps to get native java window using Java Access bridge and JDK 1.6.20.
Also Note that, As per your previous suggestion, I tried to search and call initializeAccessBridge() and shutdownAccessBridge(), But unable to succeed it. I did not find such method in Accessbridge.jar.
Please help me out.

Differences on Windows and Linux JVM about java.util.zip package

Hello, there!
I need some help if someone else has already face this problem.
I have a Java server that process the bytes of a SWF File stored in the server and ouptut it to the user through a Servlet. The file was decompressed and re-compressed using the java.util.zip package (Deflater/Inflater).
Everything works fine on Windows Server 2008 server. But now we need to migrate the server to Linux. The problem is that when I test the website now, the file seens to be corrupted.
What really intrigues me is that everything runs normal on Windows Server configuration, when changed to Linux, the final file seens to be corrupeted... what could possible be the cause? Is there any difference between java.util.zip package on Window and Linux JVM?
My Windows Server is:
. Windows Server 2008 (6.0 - x86)
. Apache 2.2.11
. Tomcat 6.0.16.0
. Java JDK 1.6.0_12-b04
My CentOS Server is
. CentOS 5.4 (2.6.18-164.15.1.el5 - i386)
. Apache 2.2.3
. Tomcat 6.0.16.0
. Java JDK 1.6.0_12-b04
Please, if someone could give me a lead, I would appreciate very much!
Thank you all in advance,

Thank you for the answer, but no. The path is correct.That's not what he meant. Zip file/directory entries are supposed to use / as the path separator. It is possible to use \ but such Zip files will only work under Windows. You may have erred here.Ohhh, I had really missunderstood what Ray said. But, I still think that this is not the problem, since the ZIP is a single SWF file generated by Flex SDK 3.4 and compressed in the ZLIB open standard (as in page 13, at [http://www.adobe.com/devnet/swf/pdf/swf_file_format_spec_v9.pdf|http://www.adobe.com/devnet/swf/pdf/swf_file_format_spec_v9.pdf] ). This is how Flash Compiler compress the files.
jschell wrote:
If the above suggestions do not solve the problem...Specify in detail with the exact steps used how you determined that it was corrupted.The reason why I believe the SWF is getting corrupted is that when it is loaded by Flash Player (in the client-side) the Player throws a VerifyError: Error # 1033. The [documentation says (see error 1033)|http://help.adobe.com/en_US/AS3LCR/Flash_10.0/runtimeErrors.html] that this error means that the SWF file is corrupted.
As I said, what intrigues me is that this work perfectly in a Windows Server 2008 server. I just had setup a CentOS server and deployed the application. The client-remains unchanged, so why could the result change?
raychen wrote:
I would remove the side effect you are doing and send the file straight through, with decompress and compress, the servlet. It is more likely that you have a bug in your swf processor than the zip library.
I had already tried it when first coding, in Windows Server 2008, it had not worked.

Executing WINWORD from both Windows and linux using Java

Dear All,
I have a problem when trying to use Runtime class to execute a winword document. My code is as follows.
Runtime r= Runtime.getRuntime();
try{
r.exec("rundll32"+" "+"url.dll,FileProtocolHandler"+" "+"WINWORD"+ " "+"file://C://welkom.doc");
catch(Exception ex){
System.out.println("Unable to open the doc file:"+ex);
When I execute this swing application with the above, the program is unable to open the specific file. And it says "Problem with the short cut, unable to open the file". When I run the program without the file name, it opens a new doc file.
Attn: what I want to do here is I need to open the winword file from both windows and linux. So I cannot use the relative path of the WINWORD.exe file.
Can anyone help me?
Thanks in advance.
Regards,
Bala

If you take a look at the api, there's an exec(String[]) method. This is the one you should use when calling a command with multiple parameters.
so something like...
String[] cmd = new String[] {"rundll32", "url.dll,FileProtocolHandler", "WINWORD", "file://C://welkom.doc"}
r.exec(cmd);
