openssl - How can I create a Certificate Service Request (CSR) from and existing public key of a key pair (assume the private key is in a safe spot elsewhere)? - Stack Overflow
http://stackoverflow.com/questions/14617306/how-can-i-create-a-certificate-service-request-csr-from-and-existing-public-keCreating a CSR from an existing private key.
openssl req -key my.key -out my.csr
You don't create it ever from a public key. Better yet, if you have a java keystore file that the private key came from, just export a public key from the java keystore instead. It might save a little grief.
keytool -export -alias mydomain -file mydomain.crt -keystore keystore.jks
