Createing CertificateChain without Key value at KeyStore

In addition here's my codes,

-

// The certificate files, to be added to keystore

FileInputStream certFile1 = new FileInputStream("root.cer");

FileInputStream certFile2 = new FileInputStream("cacert.cer");

FileInputStream certFile3 = new FileInputStream("userCert1.cer");

CertificateFactory cf = CertificateFactory.getInstance("X.509");

Certificate[] cert_arry = new Certificate[3];

// Read the 3 certificates into memory

cert_arry[0] = cf.generateCertificate(certFile1);

cert_arry[1] = cf.generateCertificate(certFile2);

cert_arry[2] = cf.generateCertificate(certFile3);

// Read the keystore file, type="jks"

KeyStore ks = KeyStore.getInstance("jks");

ks.load(null, null);

// Add certificates hierachy to keystore

ks.setCertificateEntry("ROOTCACERT", cert_arry[0]);

ks.setCertificateEntry("CACERT", cert_arry[1]);

ks.setCertificateEntry("USERCERT", cert_arry[2]);

// I want to do below, but it won't works.

Certificate[] cert_chain = ks.getCertificateChain("USERCERT");

Thanks.

Hi ejp,

Thanks again for your comments,

I fully understand what you are trying to say. I'll brief what I am now trying to do.

At MHP(DVB Data Broadcasting Spec.) has a getSingers api( see articles on that : http://forum.java.sun.com/thread.jspa?threadID=663130&messageID=3888155) for Certificate Chain information.

Data Broadcating Application usually comes with certificate chain information for Signing aplication's contents. And reciever must store that certificate chain for later use.

This is my real purpose, and I hope to use keystore or any other repository to store certificate chain information .

Sincerely.
