How to Make Tomcat Use Secure HTTP (HTTPS)
Step 1. Generate a self-signed certificate
Use the following UNIX command to create a keystore.
keytool -genkey -alias tomcat -keyalg RSA -keystore server.keystore -keysize 2048 -validity 60
You will be asked to set a passphrase; let's call it MY_PASS.
Copy the newly created server.keystore file to an appropriate location.
Step 2. Update the Tomcat server config
Add the following lines in server.xml. Note that you must customize the keystorefile and keystorePass attribute settings.
To connect to the server using HTTPS, you must specify port 8443 in the URL. For example, like this:
http://localhost:8443/Foo/
