Install a Certificate for my webapplication runing on tomcat

its ok I fix it :slight_smile: ! here the steps :
first I installed KeyStore Explorer
I creat a Store myhoststore.jks
I import the pair keys from myhost.ddns.net-chain.pem and myhost.ddns.net-key.pem And import the two certificate ca-myhost.ddns.net-crt.der and myhost.ddns.net-crt.der

in tomcat I edit the server.xml

 Connector port="8443" protocol="HTTP/1.1"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS"
	       keystoreFile="C:\Program Files\myhoststore.jks" 
	       keystorePass="xxxxxxxxxxx" keyAlias="myhostletsecript"
