JNIEXPORT jstring JNICALL Java_playaudio_BeatTrack_myBeatTrack
(JNIEnv *env, jobject obj, jstring wavfile)
{
const char* filename = env->GetStringUTFChars(wavfile,0);
BeatTrack(filename);
env->ReleaseStringUTFChars(wavfile,filename);
return NULL;
}
for my BeatTrack method, I just need the filename, then it can run,
if I comment the BeatTrack(filename);, then no problem, for the java calling,
of course, my BeatTrack(const *char filename) has no problem, cause I have test it,,
but I call this method in java, the error is as follows,
Java VM: Java HotSpot(TM) Client VM (10.0-b19 mixed mode, sharing windows-x86)
# Problematic frame:
# C [beattrack.dll+0x130b]
#
# An error report file with more information is saved as:
# D:\programs\playAudio\hs_err_pid11684.log

# If you would like to submit a bug report, please visit:

# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.
any idea??

Please clarify and help to solve the following problem:
x1 and y1 are planned to run in same server.
X1 is set to run using default port as X1.central
y1 is set to run using port 90 as Y1.central:90/
Problem is if the user specify Y1.central/ without the port # obviously it go to X1 page.
Is there any possibility to redirect the page to Y1 if the user specify Y1.central (without port number) ?
Can we do some config settings in /etc/inet.d file to route
Y1.central to Y1.central:90
Basically client also prefers the URL to be without the port #.
Is there any config need to done in inetd.d. Application will run on solaris platform.

this is not the right place to ask this.
if you're hiring, go to the job forum.
if you want others to write code for you, go to www.rentacoder.com[^]
otherwise, ask a specific and technical question...

Write a Rectangle class.
This class represents Rectangles. Each Rectange has the X and Y coordinates of its center point (as doubles) and its width and height (as double values, too). No other values should be stored! This means no area, no perimeter!
The class should have the following constructors and methods:
1. a constructor that takes X, Y, width, and height as arguments;
2. a constructor that takes only width and height as arguments;
3. a default constructor;
4. a method setCenter that takes X and Y as arguments;
5. a method setWidth that takes a width value;
6. a method setHeight that takes a height value;
7. a method getX that returns the X coordinate;
8. a method getY that returns the Y coordinate;
9. a method getWidth that returns the width value;
10. a method getHeight that returns the height value;
11. a method getArea calculates the area of the rectangle and returns it;
12. a method getPerimeter it calculates the perimeter of the rectangle and returns it;
13. a method toString that creates a String that includes the X, Y center coordinates, width, and height, and returns the string. This method does not use System.out.println() itself. It returns a String value to the caller.
Write an application (RectangleTest.java) to test your Rectangle class.
Your Application should test all the constructors and methods.
I need a submission of Both files: Rectangle.java and RectangleTest.java
please email me at T45russ@aol.com if you can write this program. I have been trying so hard and can't make it work. Thanks to all.

Hi guys, I think I'm going to lose my mind with this, I cant make my chunked transfer manager to work right.
The problem I'm having is that reading the amount of data specified in the chunk-size, I end up having the next chunk size inside the body, so, when I call the next getchunksize, it fails.
The first call to getChunkSize() works great and I get the size value as expected.
The BufferedReader is connected to the sock
<br />
s = new Socket(connectTo, portNum);<br />
sIn = new BufferedReader(new InputStreamReader(s.getInputStream()) );<br />
Thanks a lot guys, I hope any of you understands what's going on...
<br />
private String processChunked(BufferedReader sIn, String newData) throws IOException {<br />
<br />
newData += LINEBREAK;
<br />
int size = 0;<br />
String body = new String();<br />
<br />
size = getChunkSize(sIn);<br />
<br />
while(size > 0) {<br />
<br />
body = getChunkData(sIn, size); <br />
size = getChunkSize(sIn);<br />
<br />
newData += body;<br />
body = "";<br />

For more details and orderliness,here gives items to show what I want a program A could do these:
1.Supervise how much memory the program B consumed.If the program B was running and allocated memory exceeded the speciafied number,then report back to screen.
2.Restrict the priority of accessing the files out of its directory/folder to program B.Avoid running the dangerous code like system("reboot") from programs.
3.Kill the Process B if there includes any code lead to never finish running.e.g while(1){}.Of course,if a legal program run out time will be also killed.
4.How can I capture these above return messages,e.g Runtime error,stack overflow,Memory Limit Exceed.So much information just for users.
Note:This is very similar to a online judge system.
Thanks In Advance.
no cross no crown.

as long as your "judge" doesn't go inspect the binary code directly in the .class file, i don't really think most of your points can be done.
btw: No need to REPOST !!! this is a forum, not a chat, so please be patient

How wud i make an RSS Reader in Java. Provided tht i have to make an interface in Java too by using AWT or swing.... ?

Why would you use java to compile C/C++ ?¡
And for what you want to do (full control over the compilation) you should resort to something like make and predefine each and every step in the process, and calling the makefile in your exec(...)
Don't you also love the code?

I have been tasked with creating a thumbnail page that when a member clicks on the thumbnail it opens the image in a new window with all bars disabled, right clicking disabled, no status bar, no ability to resize, etc. The window should be 350x250. We want to do this without having to create any extra pages beyond the thumbnail page. I have a script already that opens the images in a new window with everything but right clicking disabled/gone. I know most people say don't disable right click, but it is on a secured members only site and we are showing possabilities for our membership to use as the mast heads for their new websites and we don't want them to be able to save the images.
