Nothing that would make it implicitly impossible although running a database on a mobile without qualifying both of those is unlikely to be generally true.
ask.sagaram wrote: any one has a solution
Solution
1. Investigate mobiles
2. Investigate databases on those mobiles
3. Pick a mobile and database (from 1 and 2)
4. Learn how to code database code on a mobile
5. Learn how java networking works and probably networking in general
6. Learn how SMS works.
7. Learn how SMS works on a mobile (which probably goes back to 1.)
8. Write code to do SMS for the mobile.
9. Combine all of the above into an application.

Hi
I have to display a DIB image in java applet through AWT Native interface. I have been able to play a live video using this technology but drawing an image is taking too long especially when the conversion of a DIB image is very difficult.
Any help in this regard would be helpful

I don't know if this might sound silly, but is it possible to interact with hardware(say an audio card in my case) using Java.

Yes, it is possible. However, without a lot more information it's impossible to suggest much more than that. If you have a specific question then please update your post above with the details.
One of these days I'm going to think of a really clever signature.

Yeah, I am sorry, but I have been asked to develop it in Java. I have used C++ before for sound operations using mmioAPIs but this project that I am going to work on contains several modules and one of the module is signal(generated by a digital hardware component) recording and replaying through different channels of a DAC card. Can this be done in Java? Anyway, the GUI of the application software should be written Java. This is must and should. I am new to Java and I use Eclipse IDE.
And I didn't down-vote you. Countered.

As to your main question I have not looked at the links that the other guys have offered but they may answer your query. I have worked on similar projects in the past and found the best solution was to write the low-level stuff in C/C++ and use the Java Native Interface[^] to access it from the Java application.

Thank you, I will look into it and get back.

Sound is a bit of a problem, most of the support has been turned down.
But yes, check this: [Java Sound API[^] @ oracle.com

In worst case you can implement your interaction in C/C++ modules for each supported platform and you can bind your native code to java via native method calls but thats a lot of work especially if you have a lot of different platforms to support. But you can reach any platform specific functionality from java if you are willing to write some platform specific C/C++ for it. In your case I would go with the sound api the guys already linked if its enough to get the job done.

Native methods in Java? I have to learn about them.

You can declare a static or instance method in java and by applying the native keyword on it you indicate for the compiler that you will provide the implementation with native code, and not in java. Then you have to write a DLL (or more DLLs) that exports the native function(s) with the appropriate names. When you java program starts you have to load the needed DLLs with System.LoadLibrary() before you call the native methods. Example: http://www.javaworld.com/javatips/jw-javatip23.html[^]
I would note that you should always try to write as much code in crossplatform java as you can and don't use native methods if you can avoid them because platform dependent stuff defeats the purpose of java.

I have an application where I need to send the values from java applet code to html page. Please help me to send the values from java code to HTML page(may be using javascript)
My java code is,
public class Calc extends Applet
{
public int tot = 0;
public void paint(Graphics g)
{
int M1 = Integer.parseInt(this.getParameter("m1"));
int M2 = Integer.parseInt(this.getParameter("m2"));
int M3 = Integer.parseInt(this.getParameter("m3"));
int M4 = Integer.parseInt(this.getParameter("m4"));
int M5 = Integer.parseInt(this.getParameter("m5"));
int M6 = Integer.parseInt(this.getParameter("m6"));
tot=M1+M2+M3+M4+M5+M6;
this.setParameter("tot",Integer.toString(tot));
g.drawString(Integer.toString(tot), 10, 10);
}
}

I have this very urgent requirement of developing a code that can extract .mp3 from .flv . I have had partial success in extracting raw bytes of mp3 from it . Now why is it that when i use something like
FileOutputStream fout=new FileOutputStream("dude.mp3");
fout.write(buffer,0,len);
assuming that buffer contains all the bytes of extracted mp3 .
Can somebody perhaps give me an alternate approach which does not involve using ffmpeg . I just want to work with bytes (it's a requirement and also no external apis).

Hi all, I'm working on a linux machine and I'd like to show via web services architecture some informations collected via linux shell acting with command like top, or ps.
My aim is to expose via web services informations of some processes that are running on my machine and these informations are available only via shell commands.
Now: how can I do this in Java? Is Java yhe best choice?
Any advice?
Thank you all,
Pietro

1. Learn how to act as a client (in a client/server setup) to get to a web service.
2. Get the information out of the returned web service call.
3. Learn how to code console output.
4. Use 3 to print the information from 2.

You have already asked this in QA
Why is common sense not common?
Never argue with an idiot. They will drag you down to their level where they are an expert.
Sometimes it takes a lot of work to be lazy

to begin with java, if u know c++ is better , but if u don't know c++. u can also learn java. u should first go through java book that is "E.balaguruswamy".
u need jdk1.5/1.7.
internet is the best source to learn self....
