Hammer & Screwdriver Question regarding keytool

I first generated jks using
Code:
keytool -genkey -alias keyAlias-keyalg RSA  -keypass changeit  -storepass changeit keystore keystore.jks

Then i generated the csr using
Code:
keytool -certreq -alias $addr  -sigalg SHA256withRSA -keystore $addr.jks -file $addr.csr

Below is how i self sign and generate the .cer from jks
Code:
Export the generated certificate to the server.cer file (or client.cer if you prefer), using the following command format:
     
keytool -export -alias keyAlias-storepass changeit  -file server.cer  -keystore keystore.jks

If you ask me why i need to generate the cer from csr instead of jks then the reason is -sigalg SHA256withRSA does not work with -genkey (jks) so i have to use .csr and then use that csr to generate the self signed .cer

Question:
How can i self sign and generate the .cer from the .csr file instead of the .jks using keytool?

NAME
wanboot_keymgmt - insert and extract keys SYNOPSIS
/usr/lib/inet/wanboot/keymgmt -i -k key_file -s keystore -o type=keytype /usr/lib/inet/wanboot/keymgmt -x -f outfile -s keystore -o type=keytype DESCRIPTION
The keymgmt utility has two purposes: o To take a raw key, stored in key_file, and insert it in the repository specified by keystore. o To extract a key of a specified type from the repository specified by keystore, depositing it in outfile. outfile will be created if it does not already exist. The type of key being added or extracted is specified by keytype and may have one of four values: 3des, aes, rsa, or sha1 (the last used by HMAC SHA-1). When extracting a key, the first key with an OID matching the supplied type is used. ARGUMENTS
The following arguments are supported: -i Used in conjunction with -k to insert a raw key in keystore. -f outfile Used to specify a file to receive an extracted key. -k key_file Used in conjunction with -i to specify the file in which a raw key is stored. This key will be inserted in keystore. -o type=keytype Specifies the type of key being inserted or extracted. Must be one of 3des, aes, rsa, or sha1. -s keystore Specifies a repository in which a key will be inserted or from which a key will be extracted. -x Used in conjunction with -f to extract a key of a specified type and deposit it in outfile.
