Is there any pure java way to convert .wav to .mp3?

Question

I\'ve struggled a lot with Java but could not combine a working example of Java .wav to .mp3 converter. This converter will be used in a Java applet so it should depend only

See this link on SourceForge http://sourceforge.net/projects/jump3r/files/

Its JAR's only (no source code), but it does work on both PC and Android, but no necessarily as described in the authors posting http://pure-java-mp3-encoder.blogspot.com.au/

I got it to work by just using the jump3r-1.0.3.jar file, as a library, and instantiated mp3.Main then used called mp3.run() e.g. part of my Android code

String[] mp3Args = {"--preset","standard",
            "-q","0",
            "-m","s",
            Environment.getExternalStorageDirectory().getPath()+"/myfile.wav",
            Environment.getExternalStorageDirectory().getPath()+"/myfile.mp3"};
    Main m = new mp3.Main();
    try
    {
        m.run(mp3Args);
    }
    catch(Exception e)
    {
        System.out.println("ERROR processing MP3 " + e);// Some bug in Android seems to cause error BufferedOutputSteam is Closed. But it still seems to work OK.
    }   

I suspect it would be possible to directly call the lame encoder passing buffers of data etc, but as the exact API for this Java version is not documented, it would require some research
