Getting rsa key and x509 cert into keystore

I would like to create an RSA key pair and an X509 cert and store both
of them in a JCA/JCE Key Store in Java2 SDK 1_4_2. I intend to use
them in another program to sign and encrypt xml documents.

I have figured out how to generate the RSA key pair using the
java.security package but I can't see any way to use it to create the
X509 cert.

Optionally, I can create the key pair and cert using openssl. Then I
can see how to import the cert from a file but not how to import the
RSA key pair from a file.

Sort of a catch22 here. I must be missing something very basic. Can
someone give me some guidance or point me to the correct place in any
documentation.

Thanks,
Paul

Use the KeyTool that comes as part of the Java SDK (possibly also the
JRE) to create your X.509 cert

I am using JDKPKCS12KeyStore from bouncy Castle
and for me it works fine

http://www.bouncycastle.org/docs/docs1.4/index.html

KeyStore ks = KeyStore.getInstance("PKCS12");
should create it.

Hope it helps
