I am using Java Keystore to generate domain.csr, domain.keystore and domain.cer. I need to secure the domain using SSL for which I need domain.crt and domain.key. How can I get these two? Is there any difference between domain.csr and domain.crt or both are same? What is difference among all extensions like csr, pem, crt, csretc.

When you generate a self signed certificate, you usually obtain a private key (.key) and a certificate (.crt)
How have you generated your domain.* files? May be domain.keystore is the key file you are looking for. Check the content of the file and see if the string ----- BEGIN PRIVATE KEY ----- is present

They are different. .csr is the certificate signing request, and .crt is the certificate signed by the Certification Authority
What is difference among all extensions like csr, pem, crt, csr etc.
From here
.DER = The DER extension is used for binary DER encoded certificates. These files may also bear the CER or the CRT extension.
.PEM = The PEM extension is used for different types of X.509v3 files which contain ASCII (Base64) armored data prefixed with a “—– BEGIN …” line. Common Extensions
.CRT = The CRT extension is used for certificates. The certificates may be encoded as binary DER or as ASCII PEM. The CER and CRT extensions are nearly synonymous.
.CER = alternate form of .crt (Microsoft Convention)
.KEY = The KEY extension is used both for public and private PKCS#8 keys. The keys may be encoded as binary DER or as ASCII PEM.
.CSR = Certificate Signing Request encoded as binary DER or as ASCII PEM. Is used to contain a certificate request to a certificate authority
