Java Security

Hi everybody,

I want to request for a certificate using a PKCS10 File.
I generate this file with this code :

package test;
import sun.security.pkcs.*;
import sun.security.x509.*;
import java.security.*;
import cryptage2.RSACryptor;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
import com.sun.crypto.provider.SunJCE;
import java.io.*;

public class TestPKCS10
{
public static void main(String argv[]){
try{
// provider
SunJCE jce = new SunJCE();
Security.addProvider(new BouncyCastleProvider());
Security.addProvider(jce);
// generate KeyPair
KeyPair pair = RSACryptor.generateKeyPair();
// get Instance of signature with MD5 algorithm
Signature dsa = Signature.getInstance("MD5withRSA");
// get Private Key
PrivateKey priv = pair.getPrivate();
// init Signature with private Key
dsa.initSign(priv);
// sign
byte[] sig = dsa.sign();
// info for X509 are in X500Name Object
X500Name x500name = new X500Name(
"Nicolas LEFEUVRE","IN","InTech","Schifflange","Luxembourg","Luxembourg");
// signer : bind Signature and X500Name
X500Signer signer = new X500Signer(dsa,x500name);
// get public Key
PublicKey publicKey = pair.getPublic();
// create PKCS10 with public key
PKCS10 pk = new PKCS10(publicKey);
// sign and encode the PKCS10
pk.encodeAndSign(signer);
// save in file PKCS10_2
PrintStream out =
new PrintStream(new FileOutputStream("c:/temp/pkcs10_2"));
}
catch(Exception e){e.printStackTrace();}
}
}

The PKCS10 look like this :

-----BEGIN NEW CERTIFICATE REQUEST-----

-----END NEW CERTIFICATE REQUEST-----

I use Microsoft Certificate Server (a service of Microsoft NT2000 server) to generate certificate, I have this message :

�The request subject name is invalid or too long. 0x80094001 (-2146877439)C�

Any idea ?
