tomcat with SSL<Invalid keystore format>

Hello everyone~!

Until now for 2days I have a problem with configuring tomcat to serve
SLL so that I can connect jsp page through https://domainame.com:8443/

I'm enumerating what I did.

$JAVA_HOME is JDK path
-------
$JAVA_HOME/bin/keytool -genkey -alias tomcat -keyalg RSA -keystore
$HOME/catest/mystore
-------
$JAVA_HOME/bin/keytool -certreq -alias tomcat -keystore $HOME/catest/
mystore -file tomcat.csr
-------
openssl ca -in tomcat.csr -out tomcat.pem -keyfile $HOME/catest/demoCA/
private/cakey.pem -days 1825
-------
openssl x509 -in tomcat.pem -out tomcat.der -outform DER
-------
keytool -import -alias ca -keystore $HOME/catest/mystore -trustcacerts
-file $HOME/catest/demoCA/cacert.pem
-------
keytool -import -alias cert -keystore $HOME/catest/mystore -file
tomcat.der
-------

And I changed setting of server.xml.Here is connector section in the
server.xml that I set up
----------------------------------------------------------------
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true"
maxThreads="150" scheme="https" secure="true"
SSLEngine="on"
keystoreFile="${user.home}/catest/mystore"
keystorePass="changeit"
clientAuth="false" sslProtocol="TLS" />
----------------------------------------------------------------
Then I stop tomcat and run it again.
Here is the output of the catalina.out and I extracted important
message.

Could you help me about this? I've scrutinized google results. But it
didn't help me.
And information about this problem is poor. You help will be
appreciated.
