Things inside jar files and zip files are entries, not files.

Seeking within an entry of a jar file or zip file would be slow,
because it's compressed.  It would be better to extract it to a real
file first.

ZipInputStream is appropriate when you want all the entries one after
the other, not when you want to randomly access entries.  InputStreams
in general aren't intended to support random access.

Is your mail address correct? I sent you a new jar to read all entries.
However, you still need to create the wav files (I believe) to play them.  I
do not play sounds in my java stuff.

Yes, I use it for binary data often.  I tried to email this new sample, but
alas address is invalid.  So, here is a version of the sample that will
recursively read zipped file entries in a jar(zipped) file, one at a time.
However, I believe you will need to create the wav files locally to play them
in java.

Sample code: tZipInJar.java
import java.io.InputStream;
import java.io.IOException;
import java.util.zip.ZipFile;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;

public class tZipInJar
{
    public static void main(String[] args) throws Exception
    {
        ZipFile         jarFile     = new ZipFile("tZipInJar.jar");
        ZipEntry        jarEntry    = jarFile.getEntry("tZipInJar.zip");
        InputStream     jarIs       = jarFile.getInputStream(jarEntry);
        ZipInputStream  zipIs       = new ZipInputStream(jarIs);

        while(true)
        {
            ZipEntry zipEntry = zipIs.getNextEntry();

                        if (null == zipEntry) break;

            int    size   = (int)zipEntry.getSize();
                        byte[] buffer = new byte[size];

                        zipIs.read(buffer,0,size);
                        System.out.println(zipEntry);
                        System.out.println(new String(buffer));

            // zipIs.closeEntry();
        }
        zipIs.close();
        jarFile.close();
    }
}

Now create three text files:

File.one:
This is the contents of file one

File.two:
This is the contents of file two

File.three:
This is the contents of file three

I use the following manifest to create an excutable jar, called tZipInJar.mf)

Manifest-Version: 1.0
Created-By: Joseph Dionne for 1.4.x and higher
Main-Class: tZipInJar

Next, compile the sample code, create tZipInJar.zip containing the three files
File.one, File.two, and File.three

Then create an excutable jar file.

jar cmf tZipInJar.mf tZipInJar.jar tZipInJar.class tZipInJar.zip

Run the jar file.
