Integration

Hello,
Recentally I purchased ssl certificate from godaddy, they send me 2 files (mydomain.crt) and (gd_bundle.crt).
now I don't know how to create .pem file just to complete the installation. below the instruction I did.

- keytool -genkey -alias client -keyalg RSA -keysize 2048 -keystore identity.jks -storepass password -keypass password

- keytool -certreq -keyalg RSA -keysize 2048 -alias client -file certreq.csr -keystore identity.jks -storepass password

here when I enter this I get an error ( keytool error: java.io.FileNotFoundException: CertChain.pem (No such file or directory not found). so how to create the CertChain.pem from the files I got from godaddy.
- keytool -import -file CertChain.pem -alias client -keystore identity.jks -storepass password

- keytool -import -file rootCA.cer -alias RootCA -keystore trust.jks -storepass password

Keytool –list –v –keystore <keystore-name> -storepass <keystore-password>
