What is J2ME?


J2ME
Java Platform, Micro Edition (Java ME) provides a robust, flexible environment for applications running on mobile and other embedded devices—mobile phones, personal digital assistants (PDAs), TV set-top boxes, and printers. Java ME includes flexible user interfaces, robust security, built-in network protocols, and support for networked and offline applications that can be downloaded dynamically. Applications based on Java ME are portable across many devices, yet leverage each device's native capabilities.

Java Security
Java security technology includes a large set of APIs, tools, and implementations of commonly used security algorithms, mechanisms, and protocols. The Java security APIs span a wide range of areas, including cryptography, public key infrastructure, secure communication, authentication, and access control. Java security technology provides the developer with a comprehensive security framework for writing applications, and also provides the user or administrator with a set of tools to securely manage applications.

How can i connect the data base during my project


That seems fine.

I cant assume your level of confidence in programming, however, following are some simple steps you can follow to achieve (for complex implementations, much more time and details will be needed, i can help u with them as well)

1. Create a database in Access ( i assume u r using Access 2003)
2. Create a System DSN (if aren't clear, how to create then goto administrative tools under control panel and you'll find Data Sources (ODBC), here u need to create System level DSN for Access driver (may be Jet 4.0+)
3. In java, you need to import java core libraries for sql (javax.sql package specially)
4. you are almost done, just google for database code in java, simple code will be around 5-10 lines (just for your reference, search with these keywords, ClassName(""), jdbc:odbc:YourDSN)
5. Open a connection using Connection object
6. Fetch the records (select query) using Recordset object
7. You're done.

thanks

How to play audio clip in java


  • Create an AudioClip object
  • Load .au sound file into AudioClip
  • Play sounds once or loop continuously
  • Stop playback


Here's how the code for these steps looks:
import java.applet.*;
AudioClip ac = getAudioClip(getCodeBase(), soundFile);
ac.play(); //play once
ac.stop(); //stop playing
ac.loop(); //play continuously


It would seem logical to use this same code to play audio clips in a Java application. Unfortunately, if you do that you will get errors from the compiler. Why? Because the AudioClip object and the getAudioClip() method are part of the java.applet package -- and are not part of applications. The good news is we can dive down and make things work ourselves.
The trick to solving this problem is to use some undocumented features that are provided by Sun in its JDK. Taking a peek inside the classes.zip file from the Sun JDK (using any of the various zipfile utilities), we find not only the standard Java packages such as java.applet but also sun.audio. (These are in the directory sun/audio.)
The sun.audio package contains everything we need to be able to play audio clips! Here's the code:
import sun.audio.*; //import the sun.audio package
import java.io.*;
//** add this into your application code as appropriate
// Open an input stream to the audio file.
InputStream in = new FileInputStream(Filename);
// Create an AudioStream object from the input stream.
AudioStream as = new AudioStream(in);
// Use the static class member "player" from class AudioPlayer to play
// clip.
AudioPlayer.player.start(as);
// Similarly, to stop the audio.
AudioPlayer.player.stop(as);


To use a URL as the audio stream source, substitute the following for the input stream and audio stream setup:
AudioStream as = new AudioStream (url.openStream());


Playing the audio stream continuously adds a bit more complexity:
// Create audio stream as discussed previously.
// Create AudioData source.
AudioData data = as.getData();
// Create ContinuousAudioDataStream.
ContinuousAudioDataStream cas = new ContinuousAudioDataStream (data);
// Play audio.
AudioPlayer.player.play (cas);
// Similarly, to stop the audio.
AudioPlayer.player.stop (cas);
