How to pull a subset of CRL list based on DistributionPoint.

Question

Problem: I've been unable to get a list of serial numbers of revoked certificates from LDAP. What I got is a string representation of a binary value, [B@95c083, which looks like a pointer.
Output:
objectclass = cRLDistributionPoint
certificaterevocationlist;binary = [B@95c083
cn = CRL1
Question:
Can anyone please take a look at the code and tell me how to go beyond the "pointer" ([B@95c083), i.e., how to get back from LDAP the CRL list associated with a Distribution Point, using Java?
Code:
import java.security.cert.X509Certificate;
import java.security.cert.X509CRL;
import java.io.DataOutputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.File;
import javax.naming.Context;
import javax.naming.directory.DirContext;
import javax.naming.directory.InitialDirContext;
import javax.naming.directory.Attributes;
import java.util.Hashtable;
public class CheckRevocationListCheck
public void performCRLCheck(Signer signer, X509Certificate signers509Cert)
try
checkCert(signer, signers509Cert);
catch(CryptoException ce)
//throw ce;
System.out.println("failed");
} // end of performCRLCheck
public void checkCert(Signer signer, X509Certificate signers509Cert) throws CryptoException
// create an output file to write results
DataOutputStream dataOutputStream= null;
try
dataOutputStream = new DataOutputStream(new FileOutputStream(new File("D:/xxxxx/ServerUnsign/CRLCheckResults.txt")));
catch(FileNotFoundException fnfe)
System.err.println("No output file created." + fnfe.toString());
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://xxxxxxxxxxx");
try
DirContext ctx = new InitialDirContext(env);
Attributes attrs = ctx.getAttributes("cn=CRL1,o=xxxxx,c=us");
System.out.println("attribute 1 = objectclass: " + attrs.get("objectclass").get());
System.out.println("attribute 2 = certificaterevocationlist: " + attrs.get("certificaterevocationlist;binary").get());
System.out.println("attribute 3 = cn: " + attrs.get("cn").get());
dataOutputStream.writeBytes("Attribute 1 = objectclass = "+ attrs.get("objectclass").get());
dataOutputStream.writeBytes("\n");
dataOutputStream.writeBytes("Attribute 2 = certificaterevocationlist;binary = " + attrs.get("certificaterevocationlist;binary").get());
dataOutputStream.writeBytes("\n");
dataOutputStream.writeBytes("Attribute 3 = cn = " + attrs.get("cn").get());
catch(Exception e)
System.err.println("Failed 1" + e.toString());
} // end of checkCert
} // end of CheckRevocationListCheck

Answer 1

Someone told me that it's a cast problem:
(byte[]) attrs.get("certificaterevocationlist;binary").get());
And I got all the serial numbers I wanted.
Thanks.
