Howto Export key from J2ME keystore

Question

I have generated a keypair with the J2ME WTK Sign MIDLet GUI tool, so the key is in the default WTK keystore (_main.ks). I need to get the key into a J2SE keystore so that I can use the keytool utility to manage the key and a certificate. How can I export the J2ME key so that I can import it into a new keystore? There is no option on the WTK tools and I have not been able to open the J2ME keystore with keytool (i.e., the format is different and I don't know what the default password is). Any help would be much appreciated.

It is sure that you can't export a private key with keytool, only in a java program...
here is a code i found in this forum , not mine, thks for it's owner...
maybe it can inspire u...
@echo off
echo Starting...
set KS=mykeystore
set ALIAS=alias
set PASS=*******
set PKEY_8_c=privatekey.pkcs8
set PKEY_64_c=privatekey.b64
set CERT_64_c=cert.cer
set CERT_12_c=privatecert.cert
java DumpPrivateKey %KS% %PASS% %ALIAS%> %PKEY_8_c%
echo -----BEGIN PRIVATE KEY-----> %PKEY_64_c%
openssl enc -in %PKEY_8_c% -a>> %PKEY_64_c%
echo.-----END PRIVATE KEY----->> %PKEY_64_c%
echo.>> %PKEY_64_c%
with DumpPrivateKey:
import java.io.FileInputStream;
import java.security.KeyStore;
import java.security.Key;
public class DumpPrivateKey {
//param 0:keystore, 1:passwd, 2: alias
        static public void main(String[] args) {
                try {
                        KeyStore ks = KeyStore.getInstance("jks");
                        ks.load(new FileInputStream(args[0]),
                                 args[1].toCharArray());
                        Key key = ks.getKey(args[2],
                                 args[1].toCharArray());
                        System.out.write(key.getEncoded());
                } catch (Exception e) {
                        e.printStackTrace();
}
